Typollama is a privacy-conscious Chrome extension that improves text directly where you write. Select text—or place the cursor in a text field—then spellcheck, proofread, rewrite, or run a custom writing instruction with the AI provider you choose.
Your text is processed only after you explicitly invoke a writing tool. Typollama has no account, analytics, or developer-operated text-processing server.
- Spellcheck fixes spelling and punctuation while preserving wording and formatting.
- Proofread & rewrite improves grammar, clarity, flow, and tone while preserving meaning.
- Custom prompt lets you define your own editing instruction.
- Use it your way with the context menu, Ctrl pressed twice/three/four times, or a recorded shortcut.
- Protect fragile editors: when a site cannot safely accept an in-place update, Typollama copies the result so you can paste it yourself.
- Keep data close by using Ollama or LM Studio, or choose a hosted provider that you already trust.
Typollama uses provider-specific request formats instead of treating every API as interchangeable. Model names remain editable because availability depends on your account and provider.
| Type | Supported providers |
|---|---|
| Hosted APIs | OpenAI, Anthropic, Google Gemini, DeepSeek, Mistral AI, Perplexity Sonar, xAI Grok, Cohere |
| OpenAI-compatible APIs | Groq, Together AI, OpenRouter, a user-supplied compatible endpoint |
| Local APIs | Ollama, LM Studio |
| Browser feature | Chrome built-in AI (preview, when available) |
Only the provider you select receives text for that request. A custom compatible endpoint asks for access to that specific origin when you save it.
- Clone or download this repository.
- In Chrome, open
chrome://extensions. - Turn on Developer mode.
- Select Load unpacked and choose this project folder.
- Open Typollama, select a provider, add its API key or local server URL, then select Save settings.
For hosted providers, create and manage API keys in the provider's own dashboard. For a local setup, start Ollama or LM Studio before invoking a writing tool.
- Click in a text field, or select the portion of an editable message that you want to improve.
- Choose Spellcheck with AI, Proofread & rewrite with AI, or Custom writing tool from the right-click menu; alternatively, use the configured shortcut.
- Wait for Typollama to finish streaming the result. It replaces the target text once, after the response is complete.
Some rich-text editors deliberately block programmatic edits. On those sites, Typollama never mutates the editor's DOM; it copies the finished result and tells you to paste it. You can also enable Copy the result instead of replacing text globally.
- Text is read only from the editor you explicitly target and is used only for the selected writing request.
- With a hosted provider, that text and the request instruction are sent to the provider you selected. With Ollama or LM Studio, requests go to the local server URL you configure.
- Settings are stored in Chrome Sync. API keys are stored in the extension's trusted local storage and encrypted with AES-GCM before storage.
- Typollama does not run analytics, sell data, or send text to a Typollama-operated backend.
