Inside the app

See it in use.

SearchThing document sidebar showing local files and indexed chunks — Keep the document index in the browser where the files are used.

SearchThing results pane showing hybrid, vector, and text search modes — Blend exact words with meaning when one kind of search is not enough.

Why we made it

The useful search box is the one that already has your files.

SearchThing keeps the index close to the documents it knows. Text search can answer immediately, local embeddings add meaning when they are ready, and the browser stores the working set without an upload step or cloud copy.
