Notion AI, but everywhere you actually write

What it does

Writely is a browser extension that injects a GPT-based writing assistant into any webpage with a text editor. Select text, click the floating “W” icon, and get help drafting emails, articles, social media replies, or translations. It runs on your own OpenAI API key across Chrome, Firefox, and Edge.

The interesting bit

The pitch is simple: Notion AI is trapped inside Notion. Most of us write in Gmail, Twitter, Reddit, random CMS boxes, and comment fields. Writely follows the cursor instead of the app, which is either liberating or slightly dystopian depending on how you feel about AI-generated Weibo clapbacks.

Key highlights

• Works on “any editor webpage” — not locked to a single platform
• Supports writing, translation, and reading assistance
• Bring-your-own-OpenAI-key model (no subscription middleman)
• Cross-browser: Chrome, Firefox, and Edge add-ons available
• Triggered by text selection with a floating contextual icon

Caveats

• Requires an OpenAI API key and manual configuration; not plug-and-play for the API-averse
• Still in Beta; the README is thin on technical architecture or privacy handling
• “Beyond Notion AI” is the project’s claim, but the README doesn’t specify concrete capabilities Notion AI lacks

Verdict

Grab it if you live in browser text fields and want consistent AI assistance without switching apps. Skip it if you need deep integration with a specific workflow or want someone else to manage API costs and rate limits.
