ThunderClaw: Run OpenClaw Agents Inside Thunderbird for Email Rewriting, Translation, and Summarization

ThunderClaw is a new extension that embeds the OpenClaw agent directly into Thunderbird, letting you rewrite, translate, and summarize emails without leaving your client. The backend runs on OpenClaw, so it works with any model you've configured there, including local models.

Key Features

• Rewrite, translate, summarize — invoke OpenClaw from selected email text.
• No send risk — the agent cannot send mail or modify recipients, attachments, or headers.
• Human-in-the-loop drafting — uses a Generate → Preview → Apply → Undo flow for every edit.
• Model-agnostic — uses OpenClaw's configuration, so you can use cloud or local models.

Requirements and Install

ThunderClaw requires OpenClaw version 2026.7.2-beta.7 or newer. Install via the official site: thunderclaw.net/#install. The source is available on GitHub.
