Contextual vs Stele

A local-first AI context engine with semantic search, temporal recall, and on-device indexing.

Shared memory for AI coding agents. Claude Code, Cursor and Codex read what your project already decided, so context survives between tools and sessions.

About Contextual

A local-first AI context engine with semantic search, temporal recall, and on-device indexing. A context engine that runs entirely on your machine, indexed, queryable, and aware of how your repository changed over time. ▸ nexus_search (query="why did we switch the webhook signer to HMAC-SHA512?", intent="mixed") . Contextual is engineered around the smallest set of ideas that make a codebase searchable through time, on a single laptop, without sending anything out. Ask "what did this file mean last quarter?" and walk the answer backwards.

About Stele

Shared memory for AI coding agents. Claude Code, Cursor and Codex read what your project already decided, so context survives between tools and sessions. Only one of these agents knows this was tried last spring and rolled back. KNOW-142 : a captcha on checkout shipped last spring and was reverted after two weeks. The bot traffic is real, though it spikes on release days and is quiet the rest of the time. A gate armed only during a release window would avoid repeating that.
