Full-text search across all your Claude conversations. Fully local, fully private. No servers. Ever lost track of an old Claude conversation? Spent minutes scrolling through chat titles trying to find an answer you know you got weeks ago?
Claude Deep Search adds full-text search across your entire Claude.ai history - something the built-in sidebar search does not do on its own.
And it's all 100% private. All conversations are stored locally (via IndexedDB) and never leave your machine.
