Best tools to search your AI chat history (2026)

Best for: Anyone who wants to search the content of their AI conversations (not just titles), across both ChatGPT and Claude, without a screen recorder or a new note-taking workflow.

Honest take: It's early software from an independent maker. Revenue is $0. No social proof to offer — just the tool working.

Best for: People who want to search across ALL their computer activity — not just AI chats, but meetings, documents, browser tabs, everything.

Honest take: If you only want your AI conversation history searchable, Rewind is overkill — and more privacy-invasive (it records your entire screen continuously). If you want total recall of your computer use, Rewind is the right tool.

Best for: People who want to write new notes and have them automatically organized and surfaced by an AI assistant.

Honest take: Mem is built for notes you create, not for AI conversations you've already had. If you want to search what you told ChatGPT three months ago, Mem won't help — it doesn't ingest ChatGPT or Claude exports. Different tool for a different job.

Best for: Researching a specific topic from a set of documents you upload manually.

Honest take: NotebookLM can accept exported conversation files as sources, so it technically works for one-off deep-dives into a specific chat. It's not designed as a persistent, searchable archive of your ongoing AI history — you'd need to upload and manage documents manually each session. Free, from Google.

Best for: Technical users who only need this occasionally and don't want to sign up for anything.

Honest take: Completely free and zero-dependency. The tradeoff: you're searching raw nested JSON (ChatGPT) or HTML (Claude), exports go stale, and there's no semantic search. Works for one-off recovery of a specific phrase. Doesn't scale as an ongoing workflow.
