# Project memory and knowledge map
> Add long-lived context to chat with project memory, the knowledge map, and the context ledger.
Desktop-only project intelligence helps the model understand your repo conventions and structure.
## Project memory
Save key conventions and notes, such as:
* Code style
* Release process
* Module boundaries
* Lessons learned
When you send, you can pick memory with `@@`. You can also turn on Memory Reference retrieval and inject it into the current turn.
Settings entry: **Settings → Project memory**.
## Project knowledge map
After AI scans the project, it builds an interactive structure map:
* File relationships
* API endpoints
* Module dependencies
* Incremental updates
## Context ledger
It shows:
* Selected or inherited context sources
* Token / character estimates
* Freshness
* Attribution confidence
Use it to see which context this turn actually carries, so you do not blow the limit by accident.
## Note cards
Local notes can be attached in chat with `@#`. They fit checklists and short scratch notes.
