02Decision guide

Choose for the product center that fits.

CHOOSE SUPERMEMORY WHEN

You want a memory API or second brain.

supermemory is the natural fit when you need a general-purpose memory layer, a second brain for personal knowledge, or an API you can integrate into your own agent or application.

CHOOSE CONTEXTSTREAM WHEN

Your next Cursor session should already know the decision.

ContextStream is built for coding projects. Code search, decisions, lessons, plans, handoffs, dependency graphs, and continuity across Cursor and Claude Code sessions should arrive as one layer.

PRICING

Test with Starter. Scale with Pro or Elite.

Pro starts at $19/month with 25,000 Context Credits, persistent memory, and full product access. Elite starts at $49/month for deeper graph context and 100,000 monthly credits. Starter includes 3,000 credits and 5-day memory retention.

PUBLISHED EVIDENCE

Read the method, not just the score.

ContextStream reports 90.0% accuracy on LongMemEval-S and 99.38% Recall@10 in its published code-search evaluation. These are ContextStream measurements on ContextStream tasks.

Evaluate ContextStream with your project.

Connect Cursor or Claude Code, index one repository, and test whether the next session retrieves a real decision and the code it affects.
