The challenge
Students have more material than time. Stubbly wanted a tool that does the heavy lifting: upload your lecture notes and get back exactly what you need to study. It had to feel simple to a first-year student while doing serious AI work in the background, and it needed paid plans from day one.
What we built
One upload. Everything you need to study.
Four features, one simple flow: students upload their material once and the platform does the rest.
- 01
Upload any PDF
Lecture notes or a textbook chapter. One drop, no setup.
- 02
Get the essentials
A clear, structured summary in seconds, written for studying.
- 03
Test yourself
Up to 30 quiz questions in multiple formats, graded instantly.
- 04
Follow a plan
A six-step setup turns exam dates into a day-by-day study plan.
Plus Free and Premium plans with monthly and yearly billing, built in from day one.
How we worked
Clickable prototype
The founder clicked through every screen before we wrote production code.
Built in six weeks
Designed and developed from zero, in focused stages with weekly check-ins.
Launched, and still building
The web app is live. The mobile app for iOS and Android is now in progress.
The handover
Everything is theirs.
No lock-in. If they ever want another team to take over, they can. Tomorrow.
Source code
The full codebase, in their own repository.
Data
Their database, their users, their content.
Accounts
Hosting, AI, billing and admin logins, all in their name.
Documentation
How it works and how to run it, written for their team.
Where it is today
Stubbly is live with 4,000+ registered users and recurring revenue from paid plans. The mobile app is on its way, and the founder owns everything: the code, the data and every account.
What's next
Stubbly goes mobile.
The web app proved the idea. Thousands of students now study with it every week. Now we're building the mobile app, so they can study wherever they are, with the same summaries, quizzes, flashcards and AI tutor in their pocket.
