Gmail AI Polisher

Rewrite selected Gmail draft text with your own AI API and replace it in place.

Gmail AI Polisher helps you rewrite text you explicitly select inside a Gmail compose window. Choose a right-click action and review the polished English version before sending. Key features: - Rewrite only the text you select in a Gmail draft. - Use your own Gemini, OpenAI, DeepSeek, or Kimi/Moonshot API key. - Gemini 3.5 Flash-Lite is the recommended default for routine email editing. Model availability, speed, and API charges depend on your provider account. - Create up to six custom right-click actions with your own editing instructions. - Work with English, non-English, or mixed-language source text and receive an English rewrite. - Use an English interface with clear connection tests and error messages. - Test your selected model and see the connection test time. - Keep an undo path with Ctrl+Z where Gmail supports it. - Protect your edits: changed selections, expired requests, and superseded results are not applied. New in version 0.3.0: - Recommended Gemini 3.5 Flash-Lite for simple email rewrites. Existing users can select Use recommended model, then Save provider. - Added bounded retries for temporary Gemini API errors, request timeouts, and detailed HTTP diagnostics. - Prevented loading messages from remaining indefinitely if the extension background stops. - Standardized built-in settings and messages in English. Privacy and data handling: - The extension does not read your inbox, recipients, contacts, subject line, attachments, browsing history, or unselected Gmail content. - Selected draft text is sent after you invoke a right-click action. Test connection sends a fixed sample email. Temporary Gemini errors may trigger up to two retries to the same selected model. - Requests go directly from your browser to your chosen AI provider. The developer operates no relay server and does not receive your text, API key, or provider response. - API keys and settings are stored locally in Chrome extension storage and are not synchronized by this extension. - The extension contains no analytics, advertising, remote scripts, or content logging. This is a bring-your-own-key extension. The extension itself charges no fee, but your selected AI provider may charge for API usage or apply its own data-retention terms. Review the provider's current pricing, privacy policy, and your organization's confidentiality rules before submitting sensitive content.
