📝 Notes

MIT‑licensed, last updated July 2025, however tested and working as of the post date with Betterbird.

Default A.I prompts may need rewriting depending on your tag preferences / conditions.

No user reviews yet, but the feature set is strong for anyone wanting automated classification or AI‑driven inbox workflows without a high level of knowledge.

Highly recommended the addon is used locally (Ollama) to prevent emails being passed to A.I cloud providers.

⚙️Technical note
When installing on Windows you need to get the addon to talk to Ollama.
1) Disable Ollama from running on windows startup.
2) You will need to run Ollama manually by opening a Powershell and entering the commands
$env:OLLAMA_ORIGINS="*"
ollama serve
3) Then in a shell load your model ollama run Qwen2.5:32B (or any other model you have downloaded with Ollama)

ThunderAI brings ChatGPT, Gemini, Claude, and even local Ollama models directly into Thunderbird, turning email management into something faster, cleaner, and far more automated.
