AI web app builder

Build a working web app from a plain-English brief.

Grafter is an AI app builder for working browser apps. Describe the workflow, refine it in chat, test the preview, publish it and export the code.

A useful app is not a pretty screen. It lets somebody finish a real job, remembers what matters and gives you a result you can inspect.

Describe the job. Get the first working path.

Prompt to first version

Tell Grafter who uses the app, what they need to do and what a successful finish looks like. It turns that brief into the screens and interactions for one complete browser-based workflow instead of stopping at a static mock-up.

  • A real user and outcome
  • Connected screens and actions
  • Useful copy instead of placeholder filler

Change the app by saying what should be different.

A coding agent, not a form wizard

Ask for a new page, a tighter workflow, a different layout or a specific fix. Grafter reads the existing project, works in the files and keeps the conversation attached to the app, so a follow-up can refer to what is already there.

  • Project-aware edits
  • Visible changed-file receipts
  • Small revisions without starting over

See the exact result on phone, tablet and desktop.

Rendered verification

The preview is the app, not a picture of what the app might become. Check the main journey at representative device widths, inspect the result after each material change and fix what does not behave as intended.

  • Live rendered preview
  • Responsive device views
  • Interaction and quality checks

Add the serious parts with the right checks.

Accounts, data and payments

When the workflow needs sign-in, saved records, payments or another service, Grafter helps define the connection and guides the setup that needs your account or approval. Those parts are tested as integrations, not painted on as pretend buttons.

  • Clear data and permission rules
  • Guided service connections
  • No invented keys or business facts

Share the app and keep the code behind it.

Publish and own it

Publish the web app to a link people can open immediately, or export the project and continue elsewhere. The result is ordinary code rather than a screenshot trapped inside a proprietary canvas.

  • A shareable web address
  • Complete project export
  • No app-store install required

Start in the browser when the browser can do the job.

Web app or native app

Portals, booking tools, dashboards, calculators, trackers and many customer workflows work well as web apps. If the idea depends on deep phone hardware, reliable offline use or an App Store release, treat native development as a separate requirement instead of hiding it in the word app.

  • Works from a link
  • Updates without an app-store release
  • An honest boundary around native features
