Capacity Desktop is an AI app builder that runs on your Mac.
Describe what you want and it builds a real web, mobile or desktop app, saved in a folder on your computer • Sign in with the Claude or ChatGPT plan you already pay for, or use an API key or a local model. No marked-up credits • Start from a complete app like a CRM or Linktree Pro or 80+ pro designs • Generate images, video, music, sound effects and 3D models inside the app • Publish to Vercel, or to a server you own, in one click.
Hey PH We're Baptiste & Samuel, and next week we're launching Capacity Desktop a free Mac app that turns plain English into real apps, built and stored on your machine.
The bet everyone tells us is wrong: move away from credits system. You plug in your own Claude / GPT / Open Router key and pay your provider at cost. Our take is that you feel the credits system is unfair, you never know what a failed fix loop just cost you, and you feel the tool profits from your retries.
A Mac app that turns plain English into real apps — built and stored on your machine, not someone else's servers. Your code, your GitHub, your own AI at cost. No marked-up credits, no lock-in. Free, no sign-up. macOS (Apple Silicon), Windows on the roadmap.
