The polyglot AI chat for Obsidian. Curtis Chat v3 rebranded and rebuilt with a breaking v1 release on 2026-07-22 — eight flagship features landed in one ship:
- Curtis Agent — AI calls tools to read/create/edit vault notes
- Multi-model arena — stream one prompt to 2 models side-by-side
- Inline diff rewrite — Cursor-style rewrite with Accept/Reject diff modal
- @-mention vault notes in chat
- Voice I/O (Whisper STT + browser TTS)
- Cross-conversation search
- Markdown export
- Memory editing UI
Plus a full type-safety pass — every external JSON response shape strictly typed, narrowing at the boundary, zero any in the provider code.
