External Software
Software that does one job well, and keeps your data yours.
We build focused desktop software. Our first app, Hark, records your meetings, transcribes them on your own computer and tells every speaker apart, so you never take notes during a call again.
Windows · Mac · Linux. Free forever for everything that runs on your computer.
Your data stays yours
Our software works on your computer. Recordings never go to our servers, and transcripts only if you turn on sync, end-to-end encrypted so we can't read them.
Free where it costs us nothing
If it runs on your computer, it's free. We only charge for things that cost us money to run, like AI and cloud sync.
Honest software
No dark patterns, no surprise renewals, no selling your data. Export everything, cancel any time, and read plain-English policies.

Specimen tracking without patient data: why we left it out
Why Track My Test identifies specimens only by accession number, how its patient status page works without patient details, and what labs gain from the design.

We started out building integrations and tracking systems for healthcare and labs, and we still take on select custom projects.
