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.
