Build your first app this weekend.
Other AI builders hand you an app. Chasm hands you the skill to build the next one yourself.
- You bring the idea
- Claude Code writes every line, and you keep it
- Chasm guides every step, from idea to live URL
One-time payment. Lifetime access. No subscription.
Chasm guides you, it does not host your app. You will also need your own Claude plan (around €20/month, mostly refundable if you use little of it) to write the code.
Chasm was built using Chasm. Every step in this product is one we walked ourselves.
The gap
The gap is not your idea.
It is the path.
Most first apps never die from being bad ideas. They die in the gap between the idea and a working product, because the path across is invisible.
Chasm makes the path visible.Eight missions. One weekend. A real URL at the end.
Other tools give you a login to their platform. Chasm gives you a real codebase on your own GitHub, a database you own, and the exact tools real developers use, so every app after this one gets easier, not just this one.

Inside Chasm
Your mission control.
Not mockups. This is the real product. Every mission tells you what to do, why it matters, and hands you the exact prompt to give the AI.
Your progress across the chasm, your active build, and today's North Star, in one glance.
What you get
Everything a first build needs.
AI-powered
North Star
One conversation turns your rough idea into a blueprint: what you are building, who it is for, and what V1 must do. Every mission after that points back to it, so you never drift.
Research missions
AI scans your market and hands you competitors, gaps, and your angle, before you build a thing.
Templates
Proven build paths for common first apps. Start from structure, not a blank page.
Idea Vault
Every new spark gets captured instead of chased. Stay on this mission; keep the next one safe.
Founder Journal
Log the journey as you go. AI reflections turn your notes into lessons for the next build.
Never lost, never stuck
A plain-language glossary for every term, and a Stuck? button on every mission that gets you moving again.
Why it works
You bring the idea
No code, no jargon. If you can describe it, you can build it.
Chasm gives the path
Eight missions that always tell you the next step, and why.
Claude Code builds it
The AI writes every line while you stay the founder, not the typist.
From the beta
Six people went first.
We handed Chasm to six friends before anyone else. These are their words, unedited.
Mathieu
IT / Technical Consultant
“It didn't just help me make the app, it taught me how to build websites with AI tools, which was a first for me and felt genuinely valuable beyond just the end product.”
Built with Chasm
A reliability checker for used motorbikes, so buyers know what to look out for
Jade
Senior Customer Success Manager
“The prompts are so good and I felt like every question I had was answered with examples.”
No app built
Her feedback shaped how Chasm works for non-coders.
Peter
Retired IT Project Manager
“As a newbie in programming I found Chasm the best app that guides you through all necessary steps and tasks to accomplish your goal of creating your own application. Clear and easy to use, it’s your route to finally turning your ideas into reality.”
Built with Chasm
A tool that forecasts share price behavior of major indexes from historical data
Flo
ICT & Game Design Graduate
“Chasm is a great app to use for when you have an idea but don’t know where to start. It guides you through all the steps and motivates you to keep going until you have a finished product. You’re always in control and because of that it feels rewarding when you finish up and launch that idea.”
Built with Chasm
An app that alerts you 20 minutes before it rains, so you never forget your umbrella
Three of the six finished with a live app. The other three, including Jade, told us exactly why they stopped, and we fixed it.
The offer
One-time payment. No subscription.
Try the first 3 missions free, no card required. Upgrade whenever you are ready to actually build. Early bird pricing on Builder and Architect while we are in launch mode, prices go up as Chasm grows. The only other thing you need is Claude (around €20 for one month, paid to Anthropic). That is the AI that writes your code, and most of that €20 is refundable if you barely use it: Anthropic offers a 14-day, usage-based refund for EU and UK accounts.

Why we built this
Neither of us is a developer. We broke our app more times than we would admit, and Chasm is the shortcut we wish we had: every mission exists because we got stuck exactly there. If we could ship a real product, so can you.
