Context that survives IDE switches

Local-first developer memory on Supermemory. Capture intent, open Context, share sanitized capsules.

Extension-first install. CLI starts your local backend. MCP connects Cursor and Claude Code to the same project graph.

Same capsule · VS Code → Cursor

Product flow

Capture → Context → Share

One continuous tour: capture in VS Code, switch to Cursor with the same capsule, let MCP answer, then share a sanitized link.

Capture

Extension + hooks write high-signal events to Supermemory — files, errors, git, failed commands.

Context

Capsule Assembler builds a structured brief on read. Same JSON in sidebar, dashboard, and MCP.

Deterministic redaction → 7-day link. Copy Markdown or Import into a local capsule.
