Sigan.beta
A time tracker for people who draw

Losing track of the time you spend drawing?
And spending even more of it proving you didn't use AI?

Both are problems of time. As you work, the recorder logs your drawing time, pen movement, and working rhythm — automatically. No timer to start, no screen capture to leave running. That one record tells you how much you actually drew, and when you need it, becomes proof that you drew it yourself.

Just draw as you always do

01

Run the recorder and draw

Work as you normally would in Clip Studio, Photoshop, and the like — the recorder captures the process alongside you.

02

Finish, and it uploads automatically

Once your account is linked, it is registered to your certificates the moment you save.

03

Prove it with a link

A single public verification link shows that you drew it yourself.

How is this different from a timer?

Both measure time. Three things are different.

A timer — counts while the window is open, drawing or not

Time you drew, not time you sat

Strokes decide. Time spent drawing, time briefly paused, and time away from the pen are counted separately. And there is nothing to press — it starts with your PC and records from the first stroke.

A timer — hours per day, and that is all

It adds up per piece

How many days and how many hours went into this one drawing stays with the drawing. Switch to another file and it splits them on its own.

A timer — the number can be edited

You cannot edit it. You can show it.

The record is sealed, so not even you can change it. Make a work public and anyone can open one link and watch the process for themselves.

The time you draw becomes your record

The recorder automatically tallies the time you actually spent drawing and resting, along with habits like pressure, speed, and rhythm. Revisit past sessions on a timeline and come to understand your own creative rhythm.

01

Drawing · idle time

The time actually spent drawing, and time spent paused, is tallied automatically.

02

Drawing habits

Your own patterns — pressure, speed, rhythm — emerge naturally.

03

Work timeline

Revisit the process in order, through the markers you left along the way.

04

Journal · calendar

See the days you kept going on a calendar, with weekly summaries and badges stacking up.

05

Looking back

“On this day” and a year in review — and set an older work beside a recent one to see what changed.

06

Draw on across devices

Move between your home and studio machines and it still adds up as one work.

What we record

A hand holding a pen carries habits entirely its own — far richer than typing ever reveals.

Pressure curve
The force of each press and its texture
Speed · accel
Line speed and deceleration through turns
Tilt · azimuth
The distinctive angle at which you hold the pen
Micro-tremor
The wobble a human hand leaves even when aiming for a straight line
Rhythm · pauses
The intervals between strokes and the rhythm of your pauses
Artwork file link
Your saved artwork file, bound by hash as proof
Your drawing type

The 16 drawing types

As your work adds up, the signals of your hand reveal a type all your own. Which of the 16 are you?

And it stands as proof that you drew it

No one can tell AI apart from a finished image alone. So we don't ‘judge’ — instead we record how you drew it, exactly as it happened, and let that be the proof.

What doesn't hold up
Guessing AI from the finished image

When an AI image is traced by hand, the strokes become genuinely human. No technology can reliably tell them apart.

What does hold up
Recording the entire process

Stroke order, the rhythm of pressure, erasures, the time spent paused. Forging all of it is harder than simply drawing the work yourself.

How that record becomes proof

Anyone can replay how it was drawn

Open the link and watch it appear, first stroke to last. You can also lay the reworked spots and the places your hand lingered right over the finished piece.

The date can never be changed later

When the certificate is made, a short fingerprint of the record is written once into the Bitcoin ledger. It's a ledger the whole world watches, so not even we can move the date. “This work already existed before that day” stops being our claim and becomes something anyone can check.

!

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.

USE 01

Commissions · Clients

Prove to a client, with a single link, that you drew it yourself.

USE 02

Contests · Art tests

Submit the process record alongside your entry to remove any doubt.

USE 03

Theft · Ghost-drawing

In a dispute, the process you kept becomes evidence that you drew it.

USE 04

Portfolio · Social

Drop a small replay window into your own site or a post, so visitors can watch the process right there.

USE 05

Artist page

Keep your verified works on one page and hand out that single address.

USE 06

Drawing together

Gather with people you know — a study group or a class — and share how much each of you drew.

What you typeNot recorded

We do not perform global keyboard hooking (keylogging), and we never store what you type. Inside your drawing app we only count how often you press undo/redo (Ctrl+Z/Y) and paste (Ctrl+V) — signals of a human at work. For a paste we also note the kind of source (web · another app · the same app), but never what you pasted or where it came from. We do not observe anything beyond the drawing app.
