What it really isCompose AI — AI-powered Chrome extension for writing autocomplete and text generation across web apps.
Our takeCompose AI embeds directly into browser text fields—Gmail, Google Docs, LinkedIn, Slack—and provides real-time autocomplete suggestions that learn your personal writing style.
The free tier is genuinely usable for light writers; the $9.99/mo Pro plan unlocks full personalization and removes generation limits. It's best understood as a lightweight, always-on copilot for everyday web writing rather than a standalone editor.
Why we rate itZero-friction install, works everywhere you already write, and the free tier provides real value before asking for a credit card.
Y Combinator-backed with 400k+ users validates product-market fit.
The catchChrome-only (no Firefox/Safari), AI suggestions can sound generic on high-stakes writing, and it's not suited for long-form content or complex document workflows.
