Honest answer: not today, as far as the project can verify. Notion is not on the Chrome extension's verified-working list, has no site-specific handling in the codebase, and the repo makes no claim that it works. This page exists to say that plainly rather than let you find out by debugging.
Why Notion is hard
Notion's editor is a bespoke block-based framework rather than a standard contenteditable or a known engine like ProseMirror or Quill. The extension's own documentation is blunt about managed editors: there is no universal programmatic write strategy that works across all of them; each engine, and even each app, has its own quirks. The verified sites (Gmail, claude.ai, ChatGPT, LinkedIn, Reddit, YouTube and others) each earned their place through engine detection and undo verification. Notion has had none of that work: no engine detector, no write-path handling, no undo testing. It might partially function through the generic fallbacks, but nothing guarantees fills land correctly or undo cleanly, so treat it as unsupported.
What to use instead
- Draft where OpenCues works, paste into Notion. Gmail compose, or any plain
<textarea>, gives you the full lookup/rewrite surface; the polished text pastes into Notion normally. Admittedly this reintroduces one copy-paste, which is the friction OpenCues exists to remove; it's a workaround, not the design. - Simple inputs on notion.so still work. The extension's reduced profile attaches to ordinary
<input>/<textarea>fields anywhere, so plain fields outside the block editor get single-answer blanks. - Native hosts are unaffected. Notion is a browser question; OpenCues in Claude Code, OpenCode, Gemini CLI, and your terminal works regardless.
Could support come later?
Structurally, yes: the extension adds managed editors one engine at a time (LinkedIn's Quill migration was absorbed this way), and Notion appears in the project's own writing as an aspiration. But per the project's publishing discipline, this FAQ doesn't promise unshipped work. If Notion support lands, the verified-sites list in the repo and this page will say so.
