AICursor project memory

Persistent project memory for Cursor.

Cursor chats reset, rules files drift, and the next session starts cold. ContextStream gives Cursor the repo knowledge, decisions, lessons, and handoffs your last session already earned, backed by code search and dependency context instead of a blank slate.

01What Cursor can carry forward

Start the next session warm.

ContextStream gives Cursor a structured place to retrieve the facts that do not belong in a one-off chat transcript.

01

Codebase evidence

Search indexed code and inspect dependency, call, dataflow, and type relationships before changing a high-blast-radius module.

02

Decisions and lessons

Retrieve why the team chose an approach, which hypotheses were eliminated, and which corrections should not be repeated.

03

Plans and handoffs

Keep implementation steps, verification state, and actionable next work available when a session or coding tool changes.

A REAL FIRST USE

Ask what the project already knows.

› Before editing auth retries, find the decision behind the current policy and show which code depends on it.

Cursor can retrieve the relevant project memory and source evidence, then explain what it found before it edits.
