Cross-Session Memory

omx can remember key insights across sessions. When a conversation is compacted, the model reflects on the session, pulls out key points, and evaluates existing ones.

How It Works​

Memory extraction runs automatically during compaction. Each memory point carries a score that shifts based on usefulness:

RatingScore Change
Helpful+3
Neutral-1
Harmful-6

Points that drop below -10 are pruned. Good insights accumulate weight over multiple sessions. Bad advice is flushed quickly. Stale knowledge decays on its own.

Enabling Memory​

Toggle cross-session memory through the preferences menu:

  1. Press Escape to open the menu
  2. Select Change preferences
  3. Toggle Cross-session memory

Storage​

Each project maintains its own memory file at .omx/memory.json. The file is a JSON array of memory points, each with a content string and a numeric score.

Edit the file directly for full control -- add project-specific knowledge, remove incorrect entries, or adjust scores manually.

What Gets Remembered​

The model decides what's worth remembering during compaction. Typical memory points include:

  • Project structure and conventions
  • Technology choices and configurations
  • Coding patterns specific to the codebase
  • Mistakes made and corrections applied
  • User preferences for code style
