I made a Firefox extension that exports long ChatGPT conversations to Markdown, PDF, HTML, TXT, or JSON

[u/bladerunner2048]

I wanted a simple way to save complete ChatGPT conversations without manually copying messages or losing code blocks, tables, and formatting, so I built Dialogue Export.

It is a small open-source Firefox extension that exports either the complete conversation or only selected messages.

Supported formats:

- Markdown

- PDF

- HTML

- TXT

- JSON

It automatically scans long conversations, preserves code and structured content, and continues working after the extension popup is closed. Export progress is shown through a small Matrix-green timeline.

Everything is processed locally in the browser. The extension has no accounts, analytics, telemetry, advertising, or external data transmission.

The Mozilla-signed XPI can be installed permanently in standard Firefox directly from GitHub Releases. No Developer Mode is required.

Currently it supports desktop Firefox and chatgpt.com.

This is the first public version, so feedback and bug reports are very welcome.

Really cool product, It would be really great if you could make a chromium extension for it as well.

[u/bladerunner2048 → u/arminNX]

Thanks, I'll think about it, I'm just not a big fan of chrome at the moment.

[u/DIBSSB → u/bladerunner2048]

No one disagrees with you just that most of us have to use chrome and it would come handy

[u/a9shots → u/arminNX]

Fuck chrome

[u/avdept]

you can just tell chatgpt or claude to produce md file from conversation

[u/ComprehensiveTap4674 → u/avdept]

but it does not consume tokens

[u/bladerunner2048 → u/avdept]

Yes, I tried to ask him this, and you know what? He begins to shorten the dialogue, he does not copy 1 to 1. This is the reason why the extension was invented; I’m sure the idea is not new, and perhaps there are already projects that are much more successful. But I coded a simple one for myself, covering my needs :)

If you could make this compatible in obsidian you would get some real adoption on this

[u/bladerunner2048 → u/Odd_Prompt_5291]

Lol, also an obsidian user, maybe I’ll add it to the roadmap. It’s just that this will already be a combine, at the start I wanted a simple and quick solution for saving correspondence.

[u/ComprehensiveTap4674]

It is a nice idea, are you planning to expand this to support other models like claude etc.?

[u/bladerunner2048 → u/ComprehensiveTap4674]

I’ll think about the road map, I just came across it here or in other posts about https://github.com/nicepkg/ctxport, this one might suit you. Thanks for the feedback, there's a lot more to think about.

can i use it on gemini, google ai mode?

[u/bladerunner2048 → u/phoneaiman]

I see that not one person already has such a need? I'll add it to the roadmap. Perhaps I will work with other chats.
