Upgrade Thunderbird with AI Superpowers

Automated Folder Sorting

InboxGenius runs incoming emails through a local or cloud LLM to classify and categorize them instantly. Urgent action items, newsletters, VIP messages, and spam are tagged and moved to their designated folders automatically based on your custom rules.

Tone Shifter & Smart Composer

Drafting emails is incredibly fast. Highlight any message or type a brief prompt to expand, summarize, fix grammar, or rewrite with professional presets directly inside Thunderbird's compose window using Gemini, OpenAI, or Ollama.

Quick Bullet Point Summary

Instantly summarize long, winding email threads into 3-5 clear, action-oriented bullet points directly from the side panel or popup window, highlighting decisions, deadlines, and next steps.

Save common templates and quickly insert them. With the Custom Placeholders settings infrastructure, you can define variables like {phone}, {office}, or {lastname} in settings, and let InboxGenius substitute them in real-time.
