Fabric vs. Readwise

Last updated April 2026

Readwise resurfaces your highlights so you don't forget what you've read. Fabric understands everything you've saved so you can work with it. Readwise is a reading retention tool: save articles, highlight passages, review them on a schedule, export to your note-taking app.

Fabric is a workspace where your reading, research, files, meeting notes, and everything else live together and the AI understands all of it. One helps you remember. The other helps you think.

Comparison table

What is Readwise?

Readwise is a reading retention system made of two parts. Readwise syncs highlights from Kindle, Apple Books, Kobo, web articles, PDFs, and podcasts into a single library, then resurfaces them via daily review emails using spaced repetition.

Reader is a read-it-later app that handles articles, PDFs, EPUBs, newsletters, RSS feeds, YouTube transcripts, and Twitter threads. You read inside Reader, highlight as you go, and everything flows into the Readwise review system. Ghostreader AI generates summaries, flashcards, and Q&A from your highlights.

The whole system exports to Obsidian, Notion, Logseq, and other note-taking apps. Readwise alone is $8.99/month. Reader alone is $8.99/month. The bundle is $13.99/month. There's a 30-day trial but no free plan. It's designed for serious readers who want to remember what they read.

What is Fabric?

Fabric is an AI workspace that combines file storage, note-taking, search, tasks, collaboration, and publishing. The Fabric Memory Engine automatically extracts, enriches, and maps relationships between everything you save. Reading material is one type of content Fabric handles.

It also stores and understands meeting recordings, design files, videos, documents, slides, and everything else. Where Readwise helps you remember passages, Fabric helps you understand how everything you've saved connects.

Key differences

Remembering vs using

Readwise's core loop is: read, highlight, review. Spaced repetition resurfaces past highlights so they stick in memory. It's effective. Studies back the approach. If your goal is to remember specific passages from books and articles, the daily review habit works.

Fabric's loop is different: save, understand, work. Everything you save is extracted, enriched, and indexed. The AI maps relationships across your library. You don't revisit highlights on a schedule. You ask the AI a question and it draws from everything you've saved. You search by meaning and find content you'd forgotten you had. The knowledge isn't in your memory. It's in the system. Readwise bets on your recall. Fabric bets on its own.

AI

Readwise's Ghostreader generates summaries, flashcards, and Q&A at the highlight level. It works within the context of what you've read. Useful for study and retention.

Fabric's AI works across your entire library. All content types, not just reading highlights. It answers questions that span everything you've saved, summarises documents, transcribes audio and video, maps relationships, and takes actions. The scope is different. Ghostreader helps you study what you've highlighted. Fabric's AI helps you think across everything you know.

Content types

Readwise handles reading content: articles, PDFs, EPUBs, newsletters, RSS, YouTube transcripts, Twitter threads, Kindle highlights, podcast notes. It's comprehensive within the reading domain.

Fabric handles reading content plus everything else: images, video, audio, documents, slides, spreadsheets, emails, design files, meeting recordings. If your knowledge comes from sources beyond what you read, Fabric covers the full range. If your knowledge is almost entirely from reading, Readwise is more specialised for that.

Search

Readwise has text search across your highlights and saved articles. Useful for finding a passage you remember highlighting.

Fabric searches by meaning across everything. Semantic search finds content even when you describe it differently. Visual search finds similar images. Colour search finds assets by palette. In-document search goes to the page, slide, or timestamp. Cross-platform search pulls from Google Drive, Notion, and Dropbox alongside your Fabric library.

The export question

Readwise is designed as a pipeline. Content flows in (from Kindle, the web, Reader), gets processed (highlights, review), and flows out (to Obsidian, Notion, Logseq). The export integrations are a core feature, not an afterthought. Many users value Readwise primarily as the bridge between their reading and their note-taking system.

Fabric is the destination. Content flows in and stays. You don't need to export to another tool because the AI, search, notes, collaboration, and publishing are all inside Fabric. If your workflow depends on a separate knowledge base in Obsidian or Notion, Readwise feeds that pipeline well. If you'd rather have everything in one place, Fabric removes the need for the pipeline.

Collaboration

Readwise is single-user. Your highlights, your reviews, your reading.

Fabric supports real-time co-editing, annotations on any content type, threaded comments, in-context chat, and shared drives.

Beyond reading

Readwise doesn't handle meeting recordings, spatial canvases, tasks, publishing, or collaboration. It handles reading. If your knowledge work is broader than reading, you need other tools for everything else.

Fabric handles all of it. Reading material sits alongside meeting notes, design references, video, tasks, and published content. One workspace instead of a reading tool plus a note-taking tool plus a file manager plus a collaboration tool plus a publishing tool.

Pricing

Readwise's bundle (Readwise + Reader) costs $13.99/month. For a reading retention tool, that's not cheap. Many users pay for Readwise alongside Obsidian (free but Sync costs $4-5/month) or Notion ($10/month), bringing the total stack cost to $18-24/month across multiple tools.

Fabric includes reading, file storage, AI, search, collaboration, publishing, and tasks. One subscription instead of stacking three.

When to use each

Use Fabric if you want everything in one place. Your reading, your files, your meeting notes, your research, your collaboration, your published content. You want AI that understands all of it together, not just your reading highlights. You don't want to maintain a pipeline between a reading app, a highlight manager, and a note-taking system. You want to use what you've saved, not just remember that you saved it.

Use Readwise if your primary workflow is deep reading with systematic highlight review. You read books on Kindle and want those highlights synced and resurfaced. You've built a daily review habit and the spaced repetition loop is central to how you learn. You use Obsidian or Notion as your knowledge base and want Readwise as the bridge between reading and note-taking. Your knowledge work is primarily text-based reading.

Use both. Some people use Readwise for the Kindle highlight sync and daily review habit, and Fabric as the workspace where all their content (including reading material) lives and connects. Readwise feeds the retention loop. Fabric provides the working context.

Why people move from Readwise to Fabric

They needed more than reading. Meeting recordings, design files, video references, slide decks, saved links. Readwise handles reading content. Everything else needed a separate tool. Fabric handles all of it.

The pipeline got complicated. Readwise to Obsidian to... somewhere. Maintaining the export chain between reading app, highlight manager, and knowledge base became overhead. Fabric removes the pipeline by being the destination.

They wanted AI across everything. Ghostreader understands your highlights. Fabric's AI understands your highlights and your documents and your meeting recordings and your saved research. The questions you can ask are different when the AI has full context.

They didn't maintain the review habit. Spaced repetition works if you do the reviews. Many people don't. The highlights accumulate, the daily emails go unread, and the retention system sits unused. Fabric's approach doesn't depend on a daily habit. The AI and search are always there.

They wanted to search by meaning. Finding a concept across months of saved material by describing what it was about, not by remembering which highlight contained it.

FAQs

Does Fabric have spaced repetition like Readwise?

No. Fabric doesn't resurface content on a review schedule. Instead, everything you save is permanently searchable, AI-queryable, and connected. The knowledge stays in the system rather than depending on your memory.

Does Fabric sync Kindle highlights?

Fabric doesn't have a direct Kindle sync. You can save reading content via the web clipper, email forwarding, or file upload. If Kindle highlight sync is essential to your workflow, Readwise handles that.

Is Fabric free?

Fabric has a free tier with limited storage and AI. Readwise has no free plan. A 30-day trial is available.

Can I use Readwise with Fabric?

Readwise exports to various formats. You could export highlights and bring them into Fabric. There's no direct integration, but the content transfers.

Which is better for remembering what you read?

Readwise's spaced repetition system is specifically designed for retention. If remembering specific passages is the goal, Readwise's daily review loop is more targeted. Fabric's approach is different: the AI remembers for you, and you query it when you need the information.

Do I need both?

If you're a heavy Kindle reader who values the daily review habit, Readwise adds something Fabric doesn't replicate. If your knowledge work goes beyond reading into files, meetings, collaboration, and diverse content types, Fabric covers ground Readwise can't. Some people use both. Many find Fabric makes the pipeline unnecessary.
