Chat Context Extractor

Extract structured AI-optimized context from any AI chat and paste into any other AI to continue seamlessly.

What It Does

When you have a great conversation with an AI, switching to a different AI means losing all context — the other AI has no idea what you discussed, what was built, or where you left off.

Chat Context Extractor solves this. It:

1. Auto-scrapes your current ChatGPT, Claude, or Gemini conversation
2. Extracts structured context — intent, memory, skills, goals, named entities, conflicts
3. Generates an AI Mega-Prompt you paste into any AI to continue the conversation instantly

No API. No account. No cloud. Runs entirely in your browser.

Troubleshooting

Could not load manifest → Make sure all 3 PNG icons exist in the icons/ folder before loading

Auto-scrape returns 0 messages → Scroll through the full conversation first, then re-scrape

Gemini scrape fails → Paste manually — Gemini's DOM changes frequently

Extension popup loses my work → Form state is auto-saved every second — reopen and it will be restored

Full mode won't scroll → Refresh the extension at chrome://extensions after updating files
