What we keep
- A made-up username, like BraveOtter42
- Their progress and what they make
- Teacher notes, reflections and check-ins
- Only the student and their teacher see their work
- All of it deleted a year after their class ends
Make something cool with technology.
Students build real STEM and business projects side by side with their teacher, a partner who guides, helps and cheers every step. Along the way they learn big ideas, grow real skills, and make something all their own they're proud to show off.
- Students build
- Teachers guide
- Everyone grows
// how it works
The build loop
Every student goes at their own pace, in any project. Their teacher follows along, never hovering, and jumps in where it counts.
- StudentThey buildReal projects, one small step at a time, in class or at home.
- TeacherYou follow alongSee where everyone is and review work as it comes in. Not to hover: to help at the right moment.
- TogetherHelp, or a high fiveThey raise a hand when they're stuck. You send a note, a hint or some encouragement, just because.
- StudentProud to share itShow it off at show-and-tell on the big screen, or take it home to show the family.
...then on to the next build, whenever they're ready
// make it yours
Same lesson. No two builds alike.
Every project teaches the same core ideas, then makes room for theirs: their choices carry through, from the first step to the last. The final build shows off who made it, and celebrates what makes them unique.

// the difference
Not your usual class
Same curious students. A whole different way to learn.
The usual: Read the chapter, answer the questions
At Cool Beans: Build something real, one small step at a time
The usual: Thirty identical worksheets
At Cool Beans: Thirty builds, no two alike, and each one's worth showing off
The usual: Everyone on the same page
At Cool Beans: Everyone at their own pace, and the teacher can see them all
The usual: Scores and red ink, a week later
At Cool Beans: What worked and what to try next, pinned right on their work
The usual: Hands waving across the room
At Cool Beans: A hand up with a reason, from right where they're stuck
The usual: Learning stops when the bell rings
At Cool Beans: Build at home too: the work and the notes are waiting
// always on
Your class works like a real team.
Students build whenever they're ready. Their teacher reviews, helps and cheers as the work comes in, in any subject. Nobody waits on anybody.
- Hands up, with a reason Stuck, looks wrong, or done? Their teacher sees it, and why.
- Feedback right on the work What worked, what to try next, and notes pinned where the fix goes.
- Send it in, keep building Big builds go to the teacher. Try again comes with a note, never a grade.
- Hints that tell you something One at a time for students. The steps that needed most show up for teachers.
- How's it going? Check-ins and reflections, so quiet students get heard too.
- The right step for every student A challenge for fast finishers, a second look for anyone who needs it.

// student data
Privacy, the simple version
Students never give us anything that says who they are, and no AI ever reads their work.
What we never ask for
- A student's real name or email
- Their age, school or location
- Photos, contacts or anything to sell
- Ads and trackers: there are none
- AI reading their work: it never does
Just trying it out? Guests can build without an account. Their progress stays on their device.
Every detail, and how long we keep it, is in our Privacy Policy.
