Perplexity vs Microsoft Copilot in 2026

Last updated September 2026

Perplexity searches the web and gives you cited answers. It works the same for everyone. No ecosystem. No subscription prerequisite. Ask a question. Get a sourced response.

Copilot works inside Microsoft. It drafts in Word, analyses in Excel, summarises in Outlook, transcribes in Teams. The search happens within your Microsoft data. The actions happen inside Microsoft apps. It's powerful if you live in M365 and invisible if you don't.
