Mail Toolbox
Export, summarize and annotate Gmail
The story
Overview
Mail Toolbox is a browser extension designed to enhance Gmail productivity by providing export, summarization, and annotation capabilities. It works directly within Gmail without requesting OAuth permissions or API access, reading only the conversation currently open in your browser. The tool offers five export formats (PDF, Markdown, HTML, EML, and plain text) with support for multiple languages and attachments. AI features include thread summarization with action items, tone-matched reply drafting, full-thread translation, and structured data extraction from invoices and bookings. Users can batch export multiple conversations into organized ZIP files or merge them into single PDFs, add private notes to conversations, and set up unread alerts across multiple accounts and labels. All export and note functionality runs locally on the user's device, with data only reaching Mail Toolbox servers when AI features are explicitly triggered. The extension is free to install with optional paid plans for expanded AI credit allowances.

FAQ
Does Mail Toolbox require Google account permissions?
No. Mail Toolbox never requests OAuth permissions or uses the Gmail API. It reads only the conversation you have open through your existing browser session.
Does the PDF export support non-Latin languages?
Yes. Mail Toolbox uses your browser's print engine with system fonts instead of embedded fonts, ensuring perfect rendering of Chinese, Japanese, Arabic, Hebrew, and all other languages.
What features work without creating an account?
Export in all five formats, batch ZIP export, private notes, and unread alerts all work without an account. Only AI features require an account since they run on Mail Toolbox servers.
How does AI pricing work?
Each AI action costs credits: summaries cost 1 credit, drafted replies cost 2 credits. All accounts start with 30 free credits, and paid plans include a monthly allowance with no per-token billing.
Which browsers are supported?
Chrome and Chromium-based browsers including Edge, Brave, Vivaldi, Arc, and Opera. A Firefox version is planned.
