Full 500-run result: matches Zep, beats supermemory.

9/9
Memory-only tasks

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

01 The problem

You already explained this. Your next agent didn't hear it.

You spend the next session repeating work the last one already settled.

You explain the repo again.

You type the same repo explanation for the third time this week.

You correct the mistake again.

You re-correct a mistake you already corrected.

You review the edits again.

You review edits you already ruled out.

With the same agent and repo, 23 of 24 tasks passed with memory connected, compared with 14 of 24 without it.

02 How it works

Explain it once.

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

1

It captures while you work

Decisions, fixes, and corrections are saved automatically and scoped to the right repo.

2

Your next session loads it before the first edit

The right project memory is ready before your agent changes code.

3

Every session starts further ahead

Each correction, fix, and decision improves what comes next.

You can also direct a save anytime.

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.

A ledger

Knowledge Stream

Stop writing context docs. See what got decided. Review it in seconds.

04 Works with your stack

Works inside Claude Code, Cursor, Codex, Cline, and Windsurf.

The same project memory follows you across tools (via MCP), so you can 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, and decisions 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.”
