Learn tech by building with Pal.
Follow the curriculum. Build games, apps and designs with Pal. Ship them to your class.
Built by students on Palstart, tested by their classmates
One AI that builds with you, teaches you, and remembers you
Pal is the builder, the tutor and the coach, and it knows everything you have made.
Builds real software with you
Describe a game, an app or a website in plain words. Pal drafts it, runs it, fixes its own mistakes and shows you a live preview. Web or phone, your choice. Every turn is tested before you see it.
pal Done. Speed now scales with level in the game loop. Try level 3.
Teaches as it goes
Pal explains what it wrote, asks you why something works, and hands you the code to change yourself. You learn by reading, breaking and fixing real things.
Remembers everything you build
Every project, every bug, every comment you received. Pal checks in once a day with one concrete thing to improve, and keeps your build streak alive.
Designs with you
Logos, icons, characters, posters. Pal writes the brief, draws options, and a critic judges them before you do. Drop the winner straight into your app.
Safe by design
Classroom rules are built into every AI call, including the ones inside apps students ship. No bad images, no bullying, no adult content. Teachers see everything.
Your classmates are your user testers
Ship to the Showcase and every builder in the class can play it. Likes and real play time move it up the board, comments tell you exactly what to fix, and your profile collects everything you have shipped and everyone who cheered it on.
From idea to a link people can open, in one sitting
Say what you want to make
A game like the one topping the app store, an app for your team, a site for your business. Pal starts from an idea, a screenshot or a trending app.
Build it together
Pal writes and runs the code, you test, question and change it. Design the look in the studio. Every save becomes a version you can go back to.
Ship it to your testers
One click gives you a real link. Put it in the Showcase, watch classmates play, read what they liked and what broke, and build version two.
Ship it. Get tested. Make it better.
Every app you ship goes in front of the whole class as its first users. They play it, like it and tell you what broke. The board ranks by real signals, so the apps people keep opening rise, and the feedback tells you exactly what to build next.
- Playtesting, built in. Classmates are your first users. You see who is playing, for how long, and what they said.
- Encouragement from peers, not just a grade. A like is a classmate saying keep going. The board ranks by how long classmates actually play, and likes and comments give that a boost.
- Version two is the lesson. Every save is a version. Shipping a fix after feedback is what real builders do, and Pal cheers it on.
The reward for shipping is other people
Nobody keeps coding for a grade. They keep coding because a classmate played their game at lunch, liked it, and told them what to fix. Palstart turns that into the loop every app goes through.
Played, not just graded
Your app is a real link. Classmates open it on their phones and the minutes they spend show up on your card. Ten minutes of someone actually playing says more than any score.
A like is a classmate saying keep going
Every like comes from a real builder who tried your app. They stack up on your profile, move you up the board, and Pal brings them up the next time you sit down to build.
Comments are your bug reports
“The duck is too slow on level 2” is user testing. Each tester gets three comments per app, so what you get is the honest stuff, not noise.
Version two is the point
Read the feedback, fix it with Pal, ship again. Your testers see v2 land and your streak moves. That is the habit real builders have.

- Several startups founded
- Years designing and building inside others
- Master’s degree
- UC Berkeley
Hire me to teach it
I teach the class, in person or online, and Palstart comes with me. Students follow the course and build the thing it is about in the same lesson, so nothing stays theory for long. There is no software for your school to buy, install or run.
Feedback stays inside the classroom. Only signed-in students and their teachers can play, like or comment. No public profiles, no strangers, no direct messages. Every comment passes an AI scan and lands in a review queue, and any app that would let students message each other is flagged before it ships.
- In person, or online from anywhere, on a laptop or a phone
- The courses, the platform and the safety rules come with the teacher
- Peer feedback in a closed classroom, reviewed by the teacher
Your first app is one message to Pal away
