Announcement · 2 August 2026
Proof of Human is now Chronatum.
Same team, same product, same mission. If you have the Mac app, there is one thing you need to do.
Why the name changed
The product outgrew the name. It started by recording whether a human was involved. It now records how a track was made: recording and MIDI activity, track structure, source material, plugin and AI-tool use, collaborators, version changes, and the production timeline.
“Proof of Human” described a subset of that, and it made people read us as an AI detector. We are not one. Chronatum is what the product actually is.
The human-contribution evidence is still there. It is now the Human Contribution module inside a bigger record.
If you have the Mac app, reinstall it once
Chronatum is a new app with a new identity, so Proof of Human will not auto-update to it. Waiting will not bring you Chronatum.
- 01
Install Chronatum and open it once.
Opening it is what moves your library across. Do not skip it.
- 02
Then remove Proof of Human.
Once Chronatum has opened, the old app is safe to remove however you like.
Why that order
Opening Chronatum once is what migrates your proof library and your settings. If you remove Proof of Human first with an uninstaller utility, that tool can delete the application-support folder the migration reads, and your library goes with it. Dragging the old app to the Trash does not remove that folder — uninstaller utilities are the risk.
In that order, your proofs, settings and consent choices all carry over.
What has not changed
- How it works
- Same capture, same proofs, same verification. The app records the same activity in the same DAWs, and the verifier reads the same files.
- Proofs you have already issued
- They verify exactly as before — the signing key did not change. Their signed statement carries the former name; that is the historical record, not a failure.
- Links you have shared
- Share links keep working. Old proofofhuman.fm addresses redirect to chronatum.com.
The API is unchanged
api.proofofhuman.fm keeps working. api.chronatum.com is the new name for the same thing: same keys, same endpoints, same request and response shapes. No integration needs to change. Nothing is being switched off, and no retirement date has been set.
