Das ist ein wirklich schönes Ergebnis, Andres – die Gasse wirkt eng und hoch, genau wie im Foto!

Paint
Outdoors or at home, at your own pace, with the course module alongside you.
Photograph your picture
Mid-way: what comes next. Finished: honest praise and no more than two suggestions.
Your reference too, if you like
Photograph what you painted from, and the coach compares.
The brush stays in your hand. The coach looks closely and talks with you, like a teacher sitting beside you at the table. It never generates pictures, it helps you make yours.
Frequently asked
- Can't I do this with a free chatbot?
- For a single critique: yes, often well. Have you done it? And again a week later? The chatbot gives no reason for the second time: no place, no path, no memory, no picture from yesterday next to today's. That is Chroma: the coach knows your last pictures, tells you the next step, marks it in the picture, and your sketchbook grows.
- Does the AI paint my picture?
- Never. The coach looks, talks and marks in the photo where something is. The brush stays in your hand.
- What does it cost, and how do I get credit?
- The first picture is free, without an account. After that we count in coffee: one coffee (CHF 3.70) covers four pictures, no subscription. Credit doesn't only come from buying: as an ambassador you get one coffee for every person who starts through your link; half a coffee for every useful hint about the app; others can give you coffee; members of associations and Urban Sketchers groups get a bonus when buying. Courses, pictures, diary and meetups are free.
- What happens to my pictures?
- They stay in Switzerland, are never used to train an AI and can be deleted at any time. As PDF or picture card you take everything with you, including the path; upload it and it is back.
- Your pictures stay yours.
- Stored in Switzerland, never used for training, never passed on. You can start without an account and delete your account at any time. More about data protection
