About
A tool I wanted for my own day.
Why it exists.
I built 11MHz because no existing tool did quite the right thing. Tasks lived in one app and notes in another. Both wanted me inside somebody's ecosystem. The price went up with every colleague I added.
In April 2026 I started on something for myself. One place for tasks and notes, in any browser, with nothing running in the background. Other people started using it. It grew from there.
What 11MHz holds to.

Your work is yours
No ads. No trackers. No data sold. Ask for an export and you get your workspace as an archive.

No AI over your work
None running, none planned. A tool for your day has no business handing it to a model.

One fair price
Personal use is free. A team pays €11 per month, whatever its size. That plan pays for 11MHz. Not ads, not your data.

The web is enough
No app store, no ecosystem. If it has a browser, it runs 11MHz.

Small on purpose
Tasks, notes, search, time. No bells and whistles. The people using 11MHz have a business to run, and not all of them are technical. Staying to the point comes before adding a feature for every request.
