Build a Daily Portrait Drawing Challenge Generator (2026)

If you want to practice faces every day, you’ve probably searched for a daily drawing challenge generator app and found the same generic tools. Here’s a better route: build your own in Auto, tuned to exactly the references and difficulty you want.

Why build it instead of downloading one

There are plenty of drawing prompt generator apps out there — from art prompt generator daily drawing challenge sites to the Oh Sketch drawing prompts app. They’re fine, but they give everyone the same prompts. You can’t say “only faces with dramatic side light” or “notify me at 4pm” or “compare my sketch to the reference.”

Auto is camera-first: you describe what you want, and it builds you a personal mini-app (a “Frame”) around it. So instead of settling, you get a portrait reference generator that fits your practice — your lighting, your session length, your schedule.

Build it in Auto in a few minutes

1. Open Auto and describe your goal in plain language: a portrait practice app that generates a fresh face reference each day, with strong light and shadow.
2. Ask for a button on the home screen to generate a new portrait whenever you want one.
3. Add a daily push notification (say, 4pm) linking to the day’s new reference.
4. Tell Auto how you like to learn — short, focused notes instead of essays.

That’s it. No code, no app store review, no waiting.

How someone built theirs

One real Auto user built exactly this. They started by asking for a learn-to-draw-portraits app that generates a new model face each day — a face with great light and shadow, ideal for study — plus a 4pm push notification with a link to the fresh reference.

Next they added a persistent button on the main screen so they could generate a new portrait anytime, not just wait for the daily drop.

Then came the feature that makes it a real feedback loop: upload your own sketch and have the app compare it against the original reference.

Their sharpest edit was about the writing. The app was spitting out long, detailed breakdowns, and they pushed back: nobody wants a six-hour study from a prompt — aim for 10–60 minutes. So they had Auto trim the text down to 2–3 short sections, each with 3–5 bullet points of what to actually look for.

That last note is the whole point of building your own: you can tune it until it matches how you work. Others have shipped their own takes too — like a Frame called Portrait Studio — proof that people are already building these instead of hunting for one.

FAQ

Do I need to know how to draw or code? Neither. You describe what you want in words; Auto builds the app. You bring the pencil.

Can I control the difficulty or style of the faces? Yes. Ask for specific lighting, angles, ages, or expressions — and change it anytime by telling Auto what to adjust.

Can it check my progress? It can. As the user above did, you can add a feature to upload your sketch and compare it side-by-side with the reference.

How long does building it take? Usually a few minutes for a first working version, then small tweaks as you use it.
