Plain-language app creation
Describe your idea in plain words and Capacity asks follow-up questions before it builds, so the output is based on what you actually want rather than a guessed interpretation.
Capacity
Capacity is a no-code, AI-assisted app builder that turns plain-language ideas into working apps. It helps people ship apps with accounts, payments, and custom domains without writing code.
What Capacity is
Capacity is a no-code, AI-assisted app builder that turns a plain-language idea into a working app. The homepage says you describe what you want in everyday language, Capacity asks a few questions to clarify the goal, and then it builds the app for you.
The product is aimed at people who want to ship real software without coding. The site says generated apps can include accounts, logins, saved information, and payments, and can be published online with a shareable link or connected to a custom domain. A separate desktop product for Mac and a landing page builder extend the same workflow into different build contexts.
Core capabilities
Real app features
The product creates working apps with accounts, logins, saved information, and payments, which makes it suitable for projects that need more than a static prototype.
Conversational editing and support
When you need to change something, you can ask in normal language and the AI explains problems and suggests next steps without exposing code or technical settings.
One-click publishing and domains
The app can be put online with a shareable link, and the site says you can connect your own domain in minutes.
Usage-based credits
Capacity uses a credit-based billing model where usage consumes credits, and the pricing page says credits never expire.
Additional builder workflows
The site also offers a desktop workflow on Mac, plus a landing page builder that can generate pages, edit them by chat, and publish them as part of a real project.
Common ways people use Capacity
Build a first app or MVP
Use Capacity when you have a product idea and want a working app without writing code. The flow is built around describing the idea, answering clarification questions, and getting a usable first version online.
Create a full-featured app
Use it for products that need user accounts, saved data, or payment flows. The site explicitly says those app components can be included, which makes it more relevant for real services than for static mockups.
Work from a Mac-based desktop setup
Use the desktop workflow on Mac if you prefer to build locally with live preview, version history, GitHub and Vercel publishing, and your own AI subscriptions.
Generate a landing page or campaign page
Use the landing page builder to create a standalone marketing page, waitlist, event page, or client brief page, then refine the result by chat and publish it to a domain.
Keep iterating on an existing project
Use the pricing and credit system when you expect ongoing iteration. The site positions credits as a way to continue building or top up an active project without changing subscriptions.
