Every decision, lesson, and insight in one feed your AI reads from.
Knowledge Stream captures the project knowledge that usually gets lost — decisions, lessons, preferences, guardrails, docs, tasks, and sessions — then makes it searchable and reusable across people, tools, and agents.
The seven things that make a project knowable.
Most of what your project has learned never reaches your AI. The Stream catches the durable parts — the things future-you, future-teammates, and future-agents need to do good work.
Decisions
Why a choice was made. The trade-offs, the constraints, the alternatives you rejected. Cited and revisable.
Lessons
What should not repeat. Hard-won corrections that turn into guardrails the next session sees first.
Preferences
How you and your team work. Pnpm over npm. Tabs over spaces. Small, durable, personal.
Guardrails
What agents should avoid. Append-only tables, no direct prod migrations, never push without tests.
Docs & tasks
Indexed READMEs, runbooks, threat models, GitHub issues, PRs — source-backed and traceable.
Sessions
What you actually built today. Turns, edits, references. Auto-linked back into the Atlas.
Notes scattered everywhere become a single, scoped feed.
Knowledge stays scattered.
- · Slack thread · 4 days ago · "we decided to…"
- · Notion doc · 2 weeks ago · half-written
- · GitHub PR · 30+ comments, never summarized
- · Zoom call · "I'll send notes later"
- · Local README · drafts/ folder · stale
- · The same lesson, lost five times.
One scoped Stream your tools read.
Tools and agents query the Stream and receive scoped context.
Through MCP, ContextStream Code, or the API — every reusable fact carries its source, its scope, and the decision graph it lives in.
The right context, at the right scope.
Every Stream event is tagged with its scope. Personal preferences stay personal. Client work stays inside client boundaries. Agents only see what they should.
Personal
Your preferences, your shortcuts, your half-formed thoughts. Yours alone, even on a team workspace.
Project
Decisions and lessons scoped to one codebase. Available to anyone with access — and to agents acting on it.
Team / workspace
Cross-project wisdom: preferred libraries, on-call runbooks, escalation lessons.
Client-safe
Redacted views for sharing with clients or contractors. Boundaries are enforced, not just documented.
Agent-visible
An explicit subset — what an agent can read, what it must avoid, what it should cite back.
Time-boxed
Some events expire. Sprint-scoped decisions vacate the active scope when the sprint ends.
Where the Stream connects.
Knowledge Atlas
The Stream is what's new. The Atlas is what's connected. See how Stream events become a queryable graph.
ContextCapsules
Bundle a slice of the Stream for one teammate, client, or agent. Scoped, expiring, revocable.
Integrations
Connect GitHub, Slack, Notion, Linear and let project activity flow into the Stream automatically.
Live in the ContextStream dashboard.
The Stream isn't a mockup. Here's the same feed running in production today — decisions, lessons, sessions, and live chips you can scope and filter by project, repo, or workspace.
Start with one decision. Add one lesson. Watch your AI remember.
Five minutes to your first reusable Stream event. No credit card to start.
