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.

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 — 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.
The offer
Lifetime access.
Build your first app for €9.
One-time payment. No subscription. The only other thing you need is Claude (about $20 for one month, paid to Anthropic) — that is the AI that writes your code.
Beta invites go out first. Join the list.
