Popup workspace — write, refine, and compare in one place

Everything you need to optimize

Built for writers, developers, and anyone who lives in AI chat UIs.

In-page floating toolbar

Select text in any textarea or editable field. Suggestion pills appear right where you work.

Popup Prompt Workspace

Write, paste, and refine longer prompts. Compare original and optimized versions side by side.

Custom prompt templates

Save your own optimization instructions and show them on the toolbar, popup, or both.

Text template library

Reusable snippets with triggers (e.g. ;;po:meeting) expand in-page as you type.

Ollama (local)

Run optimizations against your own machine. No cloud API key required when using local models.

Secure by design

API keys and libraries stay on your device—not on our servers. Optional passphrase encryption for keys.

FAQ

Updating from an older version?

Your API keys and settings are kept when you update. Guest Mode is no longer available—open Options → AI Providers and configure Gemini, OpenAI, or Ollama (Local).

Is my data sent to you?

No. The extension does not collect personal data on our servers. Prompts are sent only to the AI provider you configure when you run an optimization. See our privacy policy.

Where is my data stored? Should I back it up?

Settings and any libraries you create are saved in Chrome on this device—not in our cloud. They stay when the extension updates. They can be lost if you uninstall the extension, clear its data, or reset your browser profile. Export text templates from Options → Template Library (JSON or CSV) to keep your own copy. The popup draft is not saved automatically.

Do I need an API key?

For Gemini or OpenAI, yes—use your own keys stored locally in the browser. For Ollama, run a local server on your machine (see extension Options for setup guidance).
