I made a small local tool to turn long ChatGPT conversations into a thinking map

I made a small local prototype called Chat Atlas.

It reads a ChatGPT export `conversations.json` file in the browser and helps turn long conversations into something more useful than a normal summary.

The idea is simple:

A document can be summarized.

But a long thinking process often needs to be mapped.

For very long ChatGPT conversations, I often found that summaries preserve the conclusion but lose the path:

- how the question changed

- where assumptions shifted

- which decisions were made

- what should be carried into the next conversation

- what should be forgotten or left behind

So the tool helps generate prompts for:

- Thinking Timeline

- Decision Log

- Memory Governance

- Next Chat Handoff

- Compact Index

- GPT / Gemini / Claude review prompts

It runs locally in the browser.

The file is not uploaded to a server.

It is still an early prototype, but I wanted to share it because I think more people may run into this problem as ChatGPT conversations become longer and more important.

Do you treat long ChatGPT conversations as chat history, or as something closer to a thinking map?
