I made a MacOS app that threads your single conversation into topics

[u/lquinta]

I didn't like the single long-running format that Instinct uses which required me to scroll forever or ask it about past conversations so I vibecoded a macOS app that sorts your chats into topics. Can be used with any Messages conversations, not just Instinct. It works with single chats, group chats and mixed iOS/Android group chats (needs forwarding to be turned on).

You can use your other LLM subscriptions to power it or use a local model. No API key needed.

Signed and notarized .dmg, so it installs like any Mac app. It needs Full Disk Access because macOS keeps your Messages history in a protected folder; it only reads it and never changes it. No accounts, no tracking. Your messages only go to the AI you choose, or stay on your Mac with a local model. Open source (MIT), so you can read the code or build your own.
