Howie review: a proper scheduling assistant that lives in your inbox

Last updated October 2026

Scheduling meetings should not require a back-and-forth chain of twelve emails. And yet, for anyone whose calendar involves coordinating with people outside their own organisation, that is precisely what happens. Howie is an AI scheduling assistant built to sit inside your email and handle the entire coordination process on your behalf. You CC it on a thread, tell it what you need, and it proposes times, follows up with attendees, resolves conflicts, and books the meeting once everyone agrees.

The pitch is straightforward. Howie wants to be the executive assistant that founders, investors, and consultants have always needed but could not justify hiring full-time. It works through email, SMS, and iMessage, speaks in natural language, and handles the tedious logistics of multi-party scheduling with a degree of polish that feels closer to a well-trained human than a chatbot. Whether it delivers on that promise depends on your calendar ecosystem, your volume of external meetings, and your tolerance for a credit-based pricing model that leaves some questions unanswered.

This review covers everything you need to know about Howie in its current state: what it does well, where it falls short, how the pricing works, and who should consider it. We have drawn on publicly available product information, user reports, and competitor comparisons to give a clear picture.

What Howie is

The basics

Howie is an email-native scheduling assistant from 3030 Labs, a Seattle startup. Founded by Austin Petersmith and Dave Newman, the company emerged from a long-standing interest in AI-powered assistants. Petersmith and Newman first worked together at Assembly in 2013 and prototyped an AI assistant as early as 2015, but shelved the idea because the technology was not ready. They returned to it with Howie, launching a private beta that grew to over 1,000 paying customers before the company raised a $6 million seed round led by True Ventures in September 2025.

The core interaction model is simple. You CC Howie on an email thread, and it takes over the scheduling conversation. It reads your message, checks your Google Calendar for availability, proposes times to the other participants (displayed in their time zones), handles replies and counter-proposals, follows up with anyone who has not responded, and creates the calendar event once a time is agreed upon. It can also reschedule existing meetings, add video conferencing links, and audit your calendar for conflicts.

What sets Howie apart from link-based schedulers like Calendly is that the entire process happens within the natural flow of an email conversation. There is no booking page to share, no form to fill out. The people you are scheduling with interact with what appears to be a human assistant, not a tool. For certain professional contexts, particularly in venture capital, consulting, and executive circles, this distinction matters.

Who it's for

Howie is built for people who schedule a high volume of external meetings. The product's core customer base includes startup founders, venture capitalists, journalists, recruiters, and consultants. These are people whose work involves constant coordination with contacts outside their organisation, and who benefit from an assistant that can manage the back-and-forth without requiring their attention.

The common thread among Howie's best users is that they are on Google Workspace, they schedule primarily through email rather than booking links, and they value the impression that a professional assistant is handling their calendar. If you are an engineer who takes three meetings a week, all of them internal, Howie is probably not for you. If you are a founder running fifteen external calls a week across different time zones, it starts to make sense.

Features

Email-based scheduling and rescheduling

The heart of Howie is its email scheduling workflow. You CC Howie on any email thread where a meeting needs to be arranged, and it handles the rest. It reads the context of the conversation, understands what kind of meeting is being discussed, checks your calendar, and proposes available times. When the other party replies with a preference or a counter-proposal, Howie continues the negotiation until a time is locked in.

Rescheduling works in a similar fashion. If plans change, you can ask Howie to find a new time, and it will re-engage the participants with updated availability. The experience for the people on the other end of the thread is indistinguishable from dealing with a human coordinator. Multiple users have noted that Howie's replies read naturally, without the stilted phrasing that plagues many AI-generated emails. The company has invested in making its output feel polished and professional rather than robotic.

Group scheduling and follow-ups

Coordinating a meeting among three or more people is where Howie earns its keep. Group scheduling is notoriously difficult because it requires tracking multiple responses, identifying overlapping availability, and chasing down the person who has not replied. Howie handles all of this automatically. It monitors the thread, waits for stragglers, sends follow-up messages at appropriate intervals, and books the meeting once all parties have confirmed.

The automatic follow-up system deserves particular mention. Howie does not just propose times and wait. It actively follows up with non-respondents, which removes one of the most tedious parts of scheduling from your plate entirely. You can set preferences for how aggressively it follows up, which gives you some control over the cadence without having to manage it yourself.

Plain-language preferences and rules

Howie's preference system is one of its more thoughtful features. Rather than configuring settings through dropdown menus and toggle switches, you write your scheduling rules in plain English. You might tell Howie that pitch meetings should be 30 minutes on Zoom, that you prefer mornings for internal calls, that you need a 15-minute buffer between back-to-back meetings, or that a particular contact is a VIP who should always get your best available slot.

These preferences are stored in an open-ended document that you can update at any time. Howie applies them across all your scheduling threads, which means you set your rules once and the assistant follows them consistently. This approach is more flexible than the rigid configuration panels you find in traditional scheduling software, though it does require you to think through your preferences upfront and articulate them clearly.

Calendar management and conflict resolution

Beyond scheduling individual meetings, Howie offers a suite of calendar management features. It can create and maintain holds on your calendar, add buffer time between meetings, block out focus periods, flag scheduling conflicts, and send you daily briefings about your upcoming agenda. It also handles travel time calculations, reminders, and to-do items tied to your calendar.

Conflict auditing is particularly useful for heavy schedulers. Howie continuously monitors your calendar for overlapping events and alerts you when a conflict arises, rather than waiting for you to notice. For anyone managing a packed calendar with frequent changes, this kind of proactive monitoring saves real time and prevents the occasional double-booking that can damage professional relationships.

Time zone intelligence

Howie handles time zones gracefully. When scheduling with someone in a different time zone, Howie proposes times displayed in the other person's local time. This is a small detail that makes a significant difference in cross-border scheduling. It reduces confusion, eliminates the need for mental arithmetic, and makes the entire interaction feel more considerate.

For people who regularly schedule across multiple time zones, this feature alone can justify the subscription. The number of meetings that fall apart because someone converts a time zone incorrectly is surprisingly high, and having an assistant that handles this automatically removes an entire category of scheduling errors.

White-label and custom branding

Howie offers a white-label option that lets you present the assistant under your own brand. For an additional cost, you can give your Howie instance a custom name and a company-domain email address. Instead of your contacts seeing that "Howie" is scheduling on your behalf, they see what appears to be a named assistant at your company.

This feature is aimed at professionals and firms who want the benefits of an AI scheduler but prefer not to advertise that fact. In industries where personal relationships and the appearance of a dedicated support team matter, white-labelling lets you maintain that impression. It is a niche feature, but for the people who need it, it is difficult to find elsewhere at this price point.

Integrations

Howie connects with a growing list of third-party tools. The confirmed integrations include Zoom for video conferencing, Granola for meeting notes, Notion and Todoist for task management, Linear for project tracking, and PostHog and Stripe for product and billing data. The company's website references "many more" integrations, though the full list is not always clearly documented.

The integration with Zoom is the most immediately useful, as Howie can automatically generate and attach Zoom links to the meetings it creates. The Granola integration is interesting for users who want their scheduling assistant to connect with their meeting notes workflow, creating a more complete record of what was discussed and what needs to happen next.

Booking links

In addition to its email-based scheduling, Howie can handle booking links. It can click and process scheduling links sent by other people, which means you do not need to leave a thread to visit a Calendly or similar page. Howie handles the link on your behalf, selecting an available time that fits your preferences and calendar.

This is a nice complement to the email workflow. While Howie's primary value is in replacing booking links with a more personal interaction, the reality is that many of your contacts will still send you their own scheduling links. Having Howie process those links automatically means you spend less time bouncing between tools.

Pricing

The credit-based model

Howie moved to a credit-based pricing model in 2026, replacing an earlier structure of fixed Basic and Pro plans. The current system offers tiers ranging from $25 per month to $2,500 per month, with each tier providing a pool of shared credits. Credits are shared across your entire workspace, with no per-seat charges, so teams can pool their usage under a single subscription.

The credit tiers scale with a modest volume discount. At the $25 tier, you receive 1,250 credits at a cost of $20 per thousand. At the $2,500 tier, you receive 150,000 credits at roughly $16.67 per thousand. The discount grows gradually as you move up the scale, rewarding heavier usage without creating dramatic price breaks that pressure you into a higher tier than you need.

Tier breakdown

The entry-level tier starts at $25 per month with 1,250 shared credits. New accounts receive $25 in free credits to start, which provides enough room to test the product with a handful of scheduling interactions before committing to a paid plan.

Mid-range tiers at $100 to $500 per month provide 5,000 to 26,500 credits and suit individuals or small teams with moderate to heavy scheduling needs. The per-credit cost drops from $20 per thousand at the low end to roughly $18.87 at the $500 tier.

Higher tiers from $750 to $2,500 per month offer 41,000 to 150,000 credits and are designed for teams or power users who schedule at scale. The per-credit economics improve further, reaching $16.67 per thousand at the top tier.

Enterprise pricing is available on a custom basis, with invoicing, a data processing agreement, service-level agreements, and dedicated onboarding. This tier is aimed at larger organisations with specific compliance or support requirements.

The credit transparency problem

The most significant concern with Howie's pricing is the lack of transparency around credit consumption. Howie does not publish how many credits a typical scheduling interaction, follow-up, daily briefing, or calendar audit consumes. This makes it difficult to forecast your monthly costs or to compare Howie's pricing with alternatives on an apples-to-apples basis.

Without published burn rates, you are essentially trusting that the credits you purchase will cover your needs. The $25 starting credit helps you get a sense of usage before committing, but it would be far better if Howie provided a clear breakdown of credit costs per action. This is the kind of pricing opacity that creates friction for budget-conscious buyers, particularly those in small businesses or early-stage startups who need to track every expense.

White-label add-on

The white-label feature, which includes a custom assistant name and company-domain email, costs an additional $20 per month. This is layered on top of your chosen credit tier. For a solo founder on the $25 plan, adding white-label brings the monthly cost to $45. For a team on a higher tier, the $20 add-on is proportionally negligible.

Pros and cons

What works well

The quality of Howie's email output is its strongest asset. Users consistently report that Howie's messages read like they were written by a competent human assistant. The tone is professional without being stiff, and the scheduling proposals are clear and well-formatted. For anyone whose contacts might look sideways at an obviously automated message, this polish is valuable.

The preference system is flexible and easy to use. Writing your scheduling rules in natural language is more intuitive than navigating a settings panel, and the ability to specify different rules for different types of meetings (pitch calls versus coffee chats versus board meetings) gives you granular control without complexity.

Group scheduling and automatic follow-ups save real time. Coordinating a meeting among multiple busy people is one of the most tedious administrative tasks in professional life. Howie handles it end to end, including the follow-ups, which removes a genuine pain point.

The white-label option is a thoughtful addition for users who want the benefits of AI scheduling without broadcasting it. Few competitors offer this feature, and for professionals in relationship-driven industries, it is a meaningful differentiator.

Time zone handling is seamless. Proposing times in the recipient's local time zone is a small touch that prevents real problems. It reflects the kind of attention to detail that characterises a well-designed product.

Where it falls short

The absence of Microsoft 365 and Outlook support is a significant limitation. Howie works only with Google Calendar and requires a Google sign-in. If your organisation runs on Microsoft's ecosystem, or if you manage calendars across both platforms, Howie is simply not an option. This is the product's single largest gap, and it has been a top user request since launch.

Credit consumption is opaque. As discussed in the pricing section, Howie does not publish how many credits individual actions consume. This makes budgeting difficult and creates a trust gap that the company should address.

The hybrid human review model raises questions. Howie has historically used a team of former executive assistants to review and verify AI-generated scheduling actions. While this approach improves accuracy, it introduces potential privacy concerns. If human reviewers are reading parts of your email threads, that is worth understanding before you sign up. Howie displays SOC 2 Type II and ADA CASA compliance badges, which provides some assurance, but the company could be more transparent about the current state of human involvement in its workflow.

Speed can be an issue. Because of the review layer, Howie's responses are not always instant. The company's own FAQ once acknowledged that the product was "not that fast," attributing delays to the human verification process. For scheduling conversations where a quick reply matters, this lag can be noticeable.

The product is narrowly focused on scheduling. Howie does not handle inbox triage, general email drafting, task management beyond calendar-related items, or multi-step automations across other applications. If you want a single AI assistant that manages your entire workflow, you will need to pair Howie with other tools or look at broader platforms like Lindy.

There is no free trial beyond the initial credits. The $25 in starting credits gives you a taste of the product, but it is not a proper free trial. Once the credits are used, you must commit to a paid plan. There are no prorated refunds if you cancel mid-cycle, though access continues until the end of your billing period.

Who Howie is best for

Howie is an excellent fit for Google Workspace users who schedule a high volume of external meetings. If you are a founder taking pitch meetings, an investor coordinating with portfolio companies, a recruiter managing candidate interviews, or a consultant juggling client calls across time zones, Howie addresses a real and recurring pain point. The email-native approach means your contacts never need to learn a new tool or visit a booking page, which reduces friction on both sides of the interaction.

Teams that want a shared scheduling resource without per-seat pricing will appreciate the credit pool model. A small firm can put everyone on a single plan and share the credits, which is more economical than paying per user for each person who needs occasional scheduling help.

Professionals who value polish and presentation will find Howie's natural-sounding emails and optional white-labelling particularly appealing. In contexts where the appearance of a personal assistant matters, whether for client perception or personal brand, Howie delivers a more refined experience than most AI scheduling tools.

Who should look elsewhere

Microsoft 365 and Outlook users have no path forward with Howie. This is not a limitation you can work around. If your calendar lives in Outlook, Howie cannot access it, and you should look at alternatives like Carly, Clara, or Calendly's Callie, all of which support Microsoft's calendar ecosystem.

People who want a single AI assistant for scheduling, email, and tasks will find Howie too narrow. Platforms like Lindy bundle scheduling with inbox management, task automation, and integrations across a wider range of applications. If you want one tool to handle everything, Howie is not that tool.

Budget-conscious users who need predictable costs may find the credit model frustrating. Without clear documentation on credit consumption per action, it is difficult to know whether the $25 tier will cover your needs for a month or run out in a week. If cost predictability is important, a flat-rate tool with clearly defined usage limits may be a better fit.

Users who prioritise speed above all else should be aware that Howie's accuracy-first approach, potentially involving human review, can introduce delays. If you need instant responses in your scheduling threads, a simpler automated tool may serve you better.

Anyone concerned about data privacy in email threads should carefully review Howie's current policies regarding human review of scheduling conversations. The hybrid model, while good for accuracy, means that parts of your email threads may be read by people outside your organisation. If that is a dealbreaker, look for a fully automated alternative.

Frequently asked questions

What is Howie?

Howie is an AI-powered scheduling assistant that lives in your email inbox. You CC it on email threads, and it handles the entire scheduling process: proposing available times, following up with participants, resolving conflicts, and creating calendar events once a time is agreed upon.

How does Howie work?

You add Howie to an email thread by CCing its email address. Howie reads the conversation context, checks your Google Calendar for availability, and proposes times to the other participants. It handles replies, counter-proposals, and follow-ups automatically, booking the meeting once everyone confirms.

Does Howie work with Outlook?

No. Howie currently works only with Google Calendar and requires a Google account to sign up. Microsoft 365 and Outlook are not supported. This has been one of the most requested features since launch, but there is no confirmed timeline for when Outlook support will arrive.

How much does Howie cost?

Howie uses a credit-based pricing model with tiers ranging from $25 per month (1,250 credits) to $2,500 per month (150,000 credits). Enterprise pricing is available on a custom basis. New accounts receive $25 in free credits. The white-label feature costs an additional $20 per month.

What are Howie credits?

Credits are Howie's unit of consumption. They are shared across your workspace, with no per-seat charges. Each action Howie performs (scheduling, following up, calendar audits) consumes credits. However, Howie does not currently publish how many credits specific actions consume, which makes it difficult to forecast monthly costs.

Is there a free trial?

There is no traditional free trial. New accounts receive $25 in free credits, which allows you to test the product with a limited number of scheduling interactions. Once those credits are used, you must subscribe to a paid plan to continue using the service.

Does Howie use real humans?

Howie has historically employed a team of former executive assistants who review and verify AI-generated scheduling actions, particularly in cases where the AI's confidence is low. The company's current website is less explicit about whether this human review layer remains active. Howie displays SOC 2 Type II compliance badges, which suggests that data handling follows audited security practices regardless.

What integrations does Howie support?

Howie integrates with Google Calendar, Zoom, Granola, Notion, Todoist, Linear, PostHog, and Stripe, among others. The Zoom integration is particularly useful, as Howie can automatically generate and attach video conferencing links to the meetings it creates.

Can I use a custom name for Howie?

Yes. The white-label feature, available for an additional $20 per month, lets you give your Howie instance a custom name and a company-domain email address. Your contacts will see your chosen assistant name rather than "Howie" in their inbox.

How does Howie compare to Calendly?

Howie and Calendly take fundamentally different approaches. Calendly uses booking links that you share with contacts, while Howie works within email threads like a human assistant. Calendly supports both Google and Microsoft calendars, has a free tier, and recently launched Callie, its own email-CC scheduling assistant. Howie offers a more personal, branded experience but is limited to Google Calendar and has no free tier.

Is Howie safe to use with sensitive emails?

Howie displays SOC 2 Type II and ADA CASA compliance badges, which indicate that its security practices have been independently audited. However, the hybrid model involving potential human review of scheduling threads means that parts of your conversations may be read by Howie's team. You should review Howie's privacy policy and terms of service to determine whether this is acceptable for your use case.

Who founded Howie?

Howie was founded by Austin Petersmith (CEO) and Dave Newman. They first worked together at Assembly in 2013 and attempted an AI assistant prototype in 2015 before deciding the technology was not mature enough. The company operates as 3030 Labs and is based in Seattle. It raised a $6 million seed round in 2025 led by True Ventures, with participation from investors including Jason Calacanis and Rahul Vohra.

What happens if I run out of credits?

When your credits are exhausted, Howie stops processing scheduling requests until your credits renew at the start of your next billing cycle or you upgrade to a higher tier. There is no overage billing. If you cancel your subscription, there are no prorated refunds, but you retain access until the end of the billing period.

Can Howie schedule group meetings?

Yes. Group scheduling is one of Howie's strongest features. It tracks responses from all participants, identifies overlapping availability, follows up with people who have not responded, and books the meeting once everyone has confirmed. This works for both one-on-one and multi-party scheduling scenarios.
