Proof that you drew it
isn't in the final image
— it's in the process.
As you work, we record the movement of your pen — pressure, tilt, even the faint tremor of your hand — and seal it. What stands as proof is not the finished image, but the time you spent creating it.
We do not ‘judge’ whether a work is AI
Telling AI apart from a finished image alone is something no one can do with certainty.
So we chose proof over judgment.
When an AI image is traced by hand, the strokes become genuinely human. No technology can reliably tell them apart.
Stroke order, the rhythm of pressure, erasures, the time spent paused. Forging all of it is harder than simply drawing the work yourself.
We state this plainly: tracing — drawing over an AI image on screen — is something we cannot prevent. So we do not guarantee that ‘no AI was used.’ What we prove is how you drew it.
What the certificate is for
Evidence that you drew it yourself protects your work.
Commissions · Portfolio
Prove to a client, with a single link, that you drew it yourself.
Contests · Art tests
Submit the process record alongside your entry to remove any doubt.
Theft · Ghostwriting
In any dispute, the party who kept the process is shown to be the original author.
What we record
A hand holding a pen carries habits entirely its own — far richer than typing ever reveals.
Beyond proof — a record of your practice
The record does not end at authenticity. Your work log also captures your drawing habits and your working and resting time, helping you look back on past sessions and understand your own creative rhythm.
Working · resting time
The time actually spent drawing, and time spent paused, is tallied automatically.
Drawing habits
Your own patterns — pressure, speed, rhythm — emerge naturally.
Work timeline
Revisit the process through the markers, and the screen at each moment, that you left along the way.
We do not perform global keyboard hooking (keylogging). We collect only the pen's signals and the drawing app's activity — never what you type, nor anything beyond the drawing app.
How to begin
Run the recorder and draw
Work as you normally would in Clip Studio, Photoshop, and the like — the recorder captures the process alongside you.
Finish, and it uploads automatically
Once your account is linked, it is registered to your certificates the moment you save.
Prove it with a link
A single public verification link shows that you drew it yourself.
