Claude's web/desktop search is pretty lacking - no boolean operators, no date filtering, no advanced search syntax. So I built a fast local search tool for exported conversations (not API - this is for your regular Claude.ai chats). Supports AND/OR/NOT operators, wildcard search, date ranges, sender filtering, and more.
I think the TUI mode is particularly useful - you can navigate between conversations, jump back to Claude.ai, and copy/save artifacts directly.
I tried to make the whole process of generating exports and importing them incrementally as painless as possible. It auto-discovers export files and handles incremental updates.
