自分は、Gemini とのチャットを PDF にする、組み合わせで使っている。
最初期は「フォントが、中華フォントになってしまう」という、少し悲しい問題点があった。
しかし、現在(2026年 9月辺りから？)は、「日本語フォント」が使用されるようになった。
現状、「自分が求めていることを、ほぼ全て満たしてくれている」状態だ。
一度は試してみる価値があるだろう。

claude to md - ok
claude to pdf - codepage boxes with X. no readable text

It requires your mail address. Trying for Google AI; simply doesn't work.

gr8 extension, works well

Working Great without issues

So far it has worked well with Gemini and produced markdown that renders perfectly.

Notion integration not working. Tried support email, but never got a response. Other features work pretty well though.

The only one, that works, exporting large Gemini conversations. The only problem - can't get Notion connected.

quick and easy to use. Thank you

Another paid service that you can do yourself in less that 15 seconds.

the layout in md export is wonderful

几十万字的文本瞬间就导出，不像其他插件需要读半天，真的很快。而且支持所有主流AI，太好用了！

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.
