What it solves

ThunderAI is a Thunderbird add-on that integrates AI capabilities directly into the email client. It eliminates the need to switch between your mailbox and an external AI tool to draft, summarize, translate, or organize emails.

How it works

The add-on connects to various AI providers via API or web interface. Users can choose between cloud-based services like ChatGPT, Google Gemini, Claude, and OpenAI, or local models running via Ollama or other OpenAI-compatible servers. It provides a set of predefined email actions and automatic features that process incoming mail.

Who it’s for

Users of the Mozilla Thunderbird email client who want to leverage LLMs to automate email management, improve writing quality, and extract structured data from their messages.

Highlights

• Email Actions: Draft replies, proofread with an interactive change picker, rewrite text for tone, summarize, translate, and classify emails.
• Automatic Features: Auto-tagging, AI-powered spam filtering, and automatic summarization or translation of incoming mail.
• Customization: Support for custom prompts with data placeholders, per-prompt AI provider settings, and batch processing of multiple emails.
• Flexible Integrations: Compatible with a wide range of providers including cloud APIs (OpenAI, Gemini, Claude) and local LLMs (Ollama, LM Studio).
• Productivity Tools: Ability to extract calendar events and tasks from emails (requires ThunderAI Sparks companion add-on).
