ContextHop

Hit your limit on Claude? Continue the same work on ChatGPT, Gemini, or any other model - without explaining everything from the beginning.

ContextHop turns a finished (or interrupted) AI conversation into one portable HANDOFF.md file: a starter prompt for the new model + a clean, structured copy of your context. Paste it, and the new model picks up where the old one stopped.

No API key. No account. No server. 100% local and free.

The problem

You spend an hour building something with one AI. Then: "You've reached your limit." You open another model and waste 20 minutes re-explaining the goal, the decisions, the code, and what already failed.

Your context should travel with you, not stay locked inside one app.

Two ways to use it

Way 1 - The Magic Prompt (zero install, works on mobile)

Before your limit runs out, paste the prompt in prompts/magic_handoff_prompt.md as your last message on the old model. It writes its own handoff summary. Paste that summary into the new model. Done.

Way 2 - The Python tool

git clone https://github.com/aryancodes-dev/contexthop.git
cd contexthop
python context_hop.py your_chat.txt
# creates HANDOFF.md - fill the 3 [EDIT ME] lines, then paste/upload it in the new model

Works with transcripts exported or copied from ChatGPT, Claude, Gemini, DeepSeek and Perplexity (lines starting with User: / Claude: / etc.).

Try the example:

python context_hop.py examples/sample_chat.txt

Why not just copy-paste the whole chat?

Roadmap

• v0.1 - Python CLI + Magic Prompt
• v0.2 - Auto-detect ChatGPT / Claude JSON exports
• v0.3 - Simple web page version (paste chat -> download HANDOFF.md)
• v0.4 - Browser extension (one-click export)

Contributing

Issues and PRs welcome. Especially: export parsers for new platforms, and translations of the Magic Prompt.
