Gemini chat to markdown? Works!

it works properly in every chatbots as mentioned ,
but it failed to deliver in notebooklm.😭 which i needed the most please the dev of this add on take a look

Gemini works, but ChatGPT is broken. I never used (and won't use anymore due to ethical issues) other mainstream platforms, so I can't say anything about them.
Btw, to save full chat, you have to scroll all the way up in Gemini, until it loads everything.

I cannot Export ChatGpt session in Windows 10, Firefox latest version, I had disabled all block on all domain in site *.saveai.net

works perfect!

Amazing add-on! Quickly exports a single chat history to a ton of formats (Markdown is my favorite, but PDF is very handy too) A must have to archive import chat sessions without the rigamarole of Google Takeout.

Quick, Easy and free, Does everything it says effortlessly.

for me (Gemini user) is perfect

It still doesn't work on Grok.com! so for now 3 instead of 5.
Please fix it! It's the best extension for exporting chats, but it needs fixing.

it works perfectly for Gemini and ChatGPT (I did not try others), but I would like for it to work on Lumo by Proton, a privacy save AI.

I've been using this extension on multiple browsers for months. It's the only reliable extension for extracting full logs in various formats. Thanks a ton for your hard work, Colin
