X bookmarks → NotebookLM
You've saved hundreds of threads on X and reread almost none of them. Twimark exports them into one clean file and opens Google NotebookLM, so you can ask questions about what you saved — or listen to it as a podcast.

How it works
Twimark reads the page you already have open. It never asks for your password and never posts, likes or follows anything.
A counter shows what it finds as it scans. No copy-paste, no reformatting.
Markdown or CSV, with author, date, source link and media kept. Whole threads arrive as one piece, not fragments.
Drag the file in and start asking. Or press Audio Overview and listen to it instead.
Once it's in
What topics do I keep coming back to?[1][4]
Summarise everything I saved about pricing, and tell me where the authors disagree.[2][7]
Turn this week's bookmarks into a step-by-step checklist.[3]
What should I read first, and why?[5]
Every answer cites the post it came from, so you can click straight back to the original. And because NotebookLM builds Audio Overviews from any source, a week of saved threads becomes a six-minute podcast about things you already decided were interesting.
Private by design
You don't have to take our word for it. Click Add to Chrome and read the dialog before you confirm. Then try the same thing with any other bookmark exporter and compare what it asks for.
Pricing
The whole workflow, start to finish: export to Markdown or CSV and open NotebookLM in one click.
Your full library, whole-thread exports, and new-only syncing so you never re-export the same post twice.
The same thing, cheaper, if you already know this is part of how you work.
Everything above plus every future Pro feature. No subscription to remember.
Questions
No. Twimark reads the bookmarks page you already have open in your own browser. It never posts, likes or follows anything, and it never sees your credentials.
Yes. The export is standard Markdown. Drop it into your vault or upload it to any AI chat. CSV works for spreadsheets.
Only how you pay. Monthly, yearly at a lower rate, or once with the Founder Pass for lifetime access. The features are identical.
Yes. Monthly and yearly plans can be cancelled whenever you like, and Pro stays active until the end of the period you paid for.
X updates its site often. If an export comes back empty or incomplete, Twimark tells you rather than handing you a broken file, and you can report it in one click.
No. With Pro, Twimark remembers where you left off and exports only what you've saved since.
