01How it works

From a sentence to something real

The agent handles the specialist work. You keep the running result, the context, and the decision.

Studio workspace example: your request, preview and history in one project

  1. 01

    Describe the outcome

    Say what it does, who it is for, and what matters. Plain language is enough.

  2. 02

    Watch it get built

    The agent plans, writes, and tests in a real workspace while the app runs.

  3. 03

    Keep what works

    Review the change, restore a checkpoint, or take over the code when you want.

02Live product

The app is the artifact

Preview is not a screenshot or a mockup. It is the application, running in the browser, ready for the next decision.

  • Real UI, real interactions
  • Every change visible before it ships
  • Works on the device you are using

03Recoverable

Undo an iteration, not your progress

Every build is a checkpoint. Restore a known-good version without losing the conversation or the project.

  • Named checkpoints
  • One-click restore
  • History that stays with the project

04Open by default

Real code. No lock-in

A standard codebase, not a closed platform. Inspect it, export it, or take over whenever you want.

  • Readable diffs
  • Standard project files
  • No migration required to leave

05The agent

A collaborator that shows its work

Questions, plans, permissions, and changes stay in one thread. You always know what is happening and why.

  • Approvals before production access
  • Visible plans and tool calls
  • A clean handoff to a developer

Frequently asked questions

What is BuildWhat, and what can I build with it?

BuildWhat is an AI app builder for creating software with natural language. Build websites and web apps, native mobile apps, interactive prototypes, or presentations, then iterate with conversation, live previews, and code tools. Choose Web, Native, prototype design, or presentations according to what you want to deliver.

Can I try it before signing up, and when will I be charged?

Explore the example demos without an account. Building your own project requires an account; check the pricing page for current free credits and plans. Build usage depends on the model and actual calls. Paid plans show their price and billing cycle before checkout, while hosting and third-party services may cost extra.

Check free credits and plans
Can I start without writing code? What is vibe coding?

Start by describing your users, features, and workflow so the AI can create an initial version. This way of developing with natural-language prompts is often called vibe coding. You still need to review the result, test important flows, and configure any external services. You can inspect and edit the code when needed.

Write a useful request
Can I build native iOS and Android apps?

Native projects are for native mobile apps. Device previews, signed builds, beta distribution, and app-store releases are separate steps; available actions depend on current delivery capabilities, project state, and credentials. Store accounts, review, and third-party fees require separate preparation.

Read the Native delivery guide
How do I check AI changes and restore an earlier version?

Inspect pages and interactions in the live preview, then use application tests, change review, and project history to check the work. Checkpoints preserve verified project versions for further changes or recovery. Published applications and editable projects are managed separately.

Learn about checkpoints
How do I publish an app and understand the costs?

Preview and export your source, then choose a currently supported delivery channel. Some channels require your own hosting account, domain configuration and separate provider fees; project storage is not production hosting. Upgrading a plan does not unlock delivery channels that are not yet offered. Check the pricing page for the current delivery scope.
