How it works

How the coaching cycle works, in four steps

Everything runs in the browser. arteru is an AI-supported development and coaching system for visual artists. It does not objectively rate art. It helps you take the next step in your own work and then checks what actually changed.

1
Upload an artwork

A photo or scan of your drawing, painting or digital piece. An evenly lit image without strong distortion is enough.
Takes seconds
2
Get one concrete step

arteru proposes one concrete development step with a short reasoning and a success criterion, instead of a long list of hints.
One priority
3
Implement the step

You work on the piece in your own way and at your own pace. The step is a proposal, not an instruction.
Your work, your call
4
Compare Before and After

Upload the updated artwork. arteru compares it with the original and describes what visibly changed. Then the next cycle can begin.

What makes arteru different

A coaching loop, not a general AI chat

The whole product follows one loop: Intention → coaching step → implementation → visible change → next cycle. Every part of arteru exists to keep that loop honest.

One step, not ten hints

The coaching prioritizes. You get one task, a short reasoning and a success criterion, so you know where to start and how to tell whether it worked.

A fixed loop, not a prompt

In a general AI chat you manage context, goals and comparisons yourself. In arteru this loop is the product: one step, your update, a check against exactly that step.

Progress needs evidence

A progress statement appears only when there is sufficient visible evidence in the image. Otherwise arteru clearly explains what remains open.

No grades, no rankings

arteru does not objectively rate art and does not score your work. It describes how your image works and leaves the decision about your art to you.

Before and After

How the Before-and-After coaching works

A coaching cycle has two halves. Both belong together, and the second half is what separates coaching from a one-off opinion.

Before: A closer analysis of your uploaded artwork plus one prioritized development step. The step comes with a short reasoning and a success criterion, so it is clear what a successful change would look like.
Implementation: You implement the step in your own work. How far you take it is up to you. arteru does not repaint or edit your artwork.
After: You upload the updated artwork. arteru compares Before and After and checks the change against the step that was set at the start, not against a new opinion.
Honest result: Progress is only shown when there is sufficient visible evidence in the image. If the change is not clear enough, arteru says so and explains what remains open, instead of praising by default.

Trust and limitations

Clear edges instead of big promises

Uploading your art is a matter of trust. These rules are strict on purpose, and the limits of the system are stated just as openly as its strengths.

Operated in Germany

Website and app run on servers of netcup GmbH in Germany. No cookies and no tracking on this site.

Nothing is published without consent

A Before-and-After cycle may only be shown as an example if you actively allow it: voluntarily, per case and revocable at any time.

AI texts can be wrong

Analysis and coaching texts are generated by AI models. They are a proposal for orientation, not an expert report, and improvement is not guaranteed.

Primarily in German

The public beta and the app experience are primarily in German. arteru does not replace human art teachers or critique from people who know your work.

If one cycle per month is not enough: where paid products are offered, they are purchased in the Google Play version of arteru: a single coaching session for €2.99 as a one-off purchase, with no subscription and no automatic renewal. There is no purchase option in the browser. That amount is the German reference price, and Google Play shows the price that applies to you before you confirm.

FAQ

Short answers to the most common questions

Does arteru rate my art?

No. arteru does not rate artistic quality and does not give your work a grade or score. It describes how your image works, proposes one concrete development step and leaves the decision whether that step fits your intention to you.

How does the Before-and-After coaching work?

You upload an artwork and receive one concrete step with a short reasoning and a success criterion. You implement that step in your own work and upload the updated version. arteru compares Before and After and shows progress only when there is sufficient visible evidence. Otherwise it clearly explains what remains open.

Is arteru free?

The quick analysis is free and unlimited. One full coaching cycle per month is included, and the after comparison is part of it. If you need more, you unlock an additional coaching cycle in the Google Play version of arteru as a one-off purchase of €2.99. There is no purchase option in the browser.
