Context your agents can work with.

Learn from decisions

Capture the reason, constraints and alternatives behind a choice. Distinguish current guidance from decisions that have been superseded.

Surface conflicts and effects

Find competing guidance and relationships between decisions. Inspect the evidence before deciding what should change.

Recall what matters now

Rank relevant project history, documents, decisions and lessons for the current task, with sources you can follow.

Carry work across sessions

Save plans, progress and handoffs so another session can continue with the context it needs. Connect supported editors through MCP.

Bring knowledge beyond code

Search documents, media and reusable skills alongside project knowledge. Keep work organized in scoped workspaces and projects.

Keep control of context

Project access permissions apply to retrieval and sharing. Human team collaboration is available through Team workspaces.

Questions, answered

How is this different from saving a chat?

Saved conversation text is only part of the picture. ContextStream adds structured decisions, lessons, plans and handoffs, then retrieves relevant evidence for the task at hand.

Does every plan include decision learning?

Yes. Free includes the same core memory, decision intelligence and recall capabilities as paid plans. Credit usage and capacity vary by plan.

Does stored memory expire when credits run out?

Stored context does not expire with your monthly allowance. Metered operations resume when credits refresh or you upgrade.
