Shared project memory for people and AI agents

Stop starting
AI agents cold.

ContextStream turns repo decisions, guardrails, prior fixes, runbooks, and agent corrections into shared project memory your next AI coding session can use before it touches the repo.

start with one repo · capture real decisions · let the next session pick them up

Memory-only tasks

Passed when the needed runbook or decision was not in code.

01 The problem

Your project already learned this. Your next agent has not.

When an engineer corrects an agent, explains a repo convention, fixes a bug, or writes a runbook, that context usually stays trapped in a chat, doc, or person’s head. The next AI coding session starts from zero.

Corrections evaporate

“Don’t do that again” lives in one chat session. The next agent makes the same mistake on the same files.

Decisions go stale in docs

Why you chose this auth flow or that queue is written down somewhere — just not where an agent will look before acting.

Every session starts cold

Each run re-derives repo conventions, re-reads the codebase, and re-asks questions your project already answered.

02 How it works

Capture once. Reuse before the next run.

ContextStream keeps project memory alive across people, tools, sessions, and AI agents.

1

Capture

Save decisions, lessons, runbooks, docs, tasks, sessions, and corrections from real work.

2

Scope

Keep context tied to the right project, repo, workspace, team, or client.

3

Retrieve

Surface the right memory before an agent acts — not after it repeats a mistake.

4

Compound

Every correction, fix, and decision makes the next session better than the last.

03 The product

Shared project memory where the work happens.

One memory layer, three ways in: a stream of what your project learned, a map of how it connects, and portable bundles for handing context to the next person or agent.

Knowledge Stream

A live ledger of decisions, lessons, fixes, and corrections — captured while the work happens, reviewable in seconds.

Knowledge Atlas

A connected map of your project’s memory: which decisions touch which files, and what a change is about to break.

ContextCapsules

Scoped, revocable bundles of project memory for onboarding, handoffs, and client work — open by link, expire on schedule.

04 Works with your stack

Built for Claude Code, Cursor, Codex, Cline, Windsurf, and MCP workflows.

ContextStream ships as an MCP server, so the same project memory follows you across tools — switch agents without losing what your project knows.

05 From a real session
We asked: “How did ContextStream help you today?”
“It genuinely made me faster.”

“After a mid-day context wipe, the plan, runbook, decisions, and snapshots let me reconstruct exact state without re-deriving anything. The final epic ticket took minutes because everything already existed as referenceable IDs instead of tribal knowledge.”

Pilot it

Test it on one active repo.

Start with a small workspace. Capture a few real decisions, runbooks, and agent corrections, then test whether the next AI coding session starts with the right context.
