RecollectViewer is a free Windows app that loads exported chat history from ChatGPT, Gemini, and Claude into one offline viewer. Browse conversations in a tree, run cross-AI full-text search with advanced filters (code-only, attachments, date range, and more), and jump back to the original thread. New in v1.4: Second Opinion — export a conversation to text in one click and hand it to another AI for a different perspective, with full prior context. No cloud upload. Your history stays on your PC.

Hi everyone — I’m the maker of RecollectViewer.

I got tired of losing prompts and code snippets across ChatGPT, Gemini, and Claude exports. So I built a fully offline Windows viewer: one tree, cross-AI search, and filters that match how I actually dig through old chats.

v1.4 adds Second Opinion — export the current conversation and pass the full context to another model for a second look (plans, fact-checks, research reviews).

It’s free and portable. I’d love feedback from anyone juggling multiple AIs.

Requirements: Windows 10/11, .NET Framework 4.7.2+, WebView2 Runtime.
