Zero Friction.
Back to the Core.
Zeroback builds micro AI that lives in your browser.
Highlight, click, process — the web page in front of you becomes structured data you can actually use, without leaving the tab.
No software to install beyond a browser extension.
We pick the model that fits the job. Bigger rarely helps.
Built in Seoul.
Turn the web into your database
Most of the work isn't thinking. It's selecting, copying, reformatting and pasting the same thing between two tabs. That's the part we take.
The screen is the input
The extension reads the page you're already on and understands its context. Nothing to upload, no API to wire up, no scraper to maintain.
Structured, not summarized
Complex pages come back as clean rows and fields you can drop into a sheet, a form, or the next tool in your workflow.
Light and quiet
A micro AI, not a platform. It sits in your browser until you need it, does one job, and gets out of the way.
Three steps, one tab
Nothing leaves the page you're working on.
Select what matters
Drag over the part of the page you care about, or let the extension pick out the repeating structure for you.
The AI reads the context
It works out what the content actually is — a listing, a table, a transcript — and shapes it into the format you asked for.
Results land where you work
Copy it, export it, or push it straight into the tool waiting on the other side. No second window, no round trip.
What we're building
Zeroback builds small, single-purpose AI extensions for the browser. Noteback is the first one.
Noteback
Coming soonStop watching, start knowing. Noteback reads the subtitles of the lecture you're watching and turns hours of video into notes you can actually study from, by the time it ends.
Next extension
UndecidedWe'll pick another round trip people make between tabs every day and build that next. If you have one, tell us about it.
Ready to start from zero?
We're building this now and looking for the first people to use it.
If your day involves moving data between tabs, tell us what you're still doing by hand — it's read and answered by the people building it.
