Contextual vs NodePad

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 NodePad

Agent on canvas. NodePad lays your AI conversations out on a canvas, so you try more ideas, keep the answers that hold up, and never lose the thread that mattered. You can then use the arrow keys to move the node around. You can then press delete to remove it or escape to cancel. Every message on a NodePad canvas is a node you can build on, and the model only ever sees the context you chose.
