RevX gives you a browser-based IDE, scaffolds a Product from a natural-language prompt, and publishes it to a `.dot` name after you sign the final step with the Polkadot App. This route does not require a local development environment. By the end, you will have configured an AI provider in App Builder, generated a Polkadot Product from a prompt, inspected the generated code, and published it to `.dot`. :::caution[TestNet names end in `.paseo`, not `.dot`] dotNS top-level domains are per network. On Paseo Next v2, the TestNet the Apps tooling targets by default, names are minted under `.paseo`: publish `myproject57` and you get `myproject57.paseo`, served at `https://myproject57.paseo.li`. Whether you supply the bare label or the full name depends on the tool; see [Choose a Name](/apps/register-dot-domain/#choose-a-name). ::: :::note[Products Devnet] This page uses Paseo Next v2 (`paseo` preset). For the PCF Products Devnet (`devnet` preset), see [Get started as a developer](/apps/get-started/developers/). ::: ## Prerequisites Before starting, make sure you have: - The [Polkadot App](/apps/) installed on your phone with an account created; it signs the final publish step. - An API key for an AI provider supported by App Builder, such as OpenAI or Anthropic. ## Open RevX Open [RevX](https://revx.dev/) in your browser. RevX is a browser-based IDE; you will use the App Builder track to scaffold a Polkadot Product end to end. ![RevX IDE landing view showing the main workspace](/images/apps/quick-start/revx/revx-01.webp) ## Open App Builder From the sidebar, select **App Builder**. App Builder is RevX's track for generating Polkadot Products using AI-assisted workflows. ![RevX sidebar with the App Builder option highlighted](/images/apps/quick-start/revx/revx-02.webp) ## Create a New App Click **Create App** to start a new project. RevX automatically installs the required dependencies and initializes the project environment so you can move straight into configuration and prompting. ![RevX App Builder showing the Create App action and the initialized project environment](/images/apps/quick-start/revx/revx-03.webp) After clicking **Create App**, you will see a loading screen while the IDE initializes the project environment. ![RevX App Builder showing the loading screen while the IDE initializes the project environment](/images/apps/quick-start/revx/revx-04.webp) :::note Initial setup may take a moment while dependencies install. Wait for the environment to finish initializing before configuring the builder. ::: Once the environment is initialized, you will see a minimal app scaffolded in the editor and running in the terminal. ![RevX App Builder showing the minimal app scaffolded in the editor and running in the terminal](/images/apps/quick-start/revx/revx-05.webp) ## Configure the Builder From the App Builder view, click the **Settings** icon to open the AI configuration panel. ![RevX App Builder settings icon](/images/apps/quick-start/revx/revx-06.webp) Configure the following: - **AI provider**: The backend service that powers code generation. - **API key**: The credential for your AI provider. - **Model**: The specific model to use from the selected provider. ![RevX App Builder configuration panel showing API key, AI provider, and model fields](/images/apps/quick-start/revx/revx-07.webp) These settings let the IDE generate applications using the selected AI backend. You can change them at any time if you want to switch providers or models. ## Generate an App Use the chat interface to describe the app you want to build. RevX generates the application structure and code automatically based on your prompt. :::note[Example prompt] Build a Product that shows the balance of Alice (a standard Substrate dev account) ::: After you submit the prompt, the IDE produces the project files and scaffolds the app for you to review. ![RevX chat interface with a prompt entered and the generated app structure on the right](/images/apps/quick-start/revx/revx-08.webp) :::tip Keep prompts concrete and scoped. Short, specific prompts tend to produce app structures that are easier to review and iterate on. ::: ## Inspect the Generated Code Once generation completes, open the generated files in the editor to review what was produced. You can continue iterating on the application from within RevX: refine the prompt, edit code directly, or layer additional changes through the chat interface. ![RevX editor showing the generated app source files open for inspection](/images/apps/quick-start/revx/revx-09.webp) ## Publish to `.dot` When your app is ready, click **Publish to .dot** to deploy the application to the Polkadot ecosystem. The publish action takes the app you generated in RevX and makes it available under a `.dot` name. ![RevX App Builder showing the Publish to .dot action](/images/apps/quick-start/revx/revx-10.webp) After clicking **Start Deploy**, you will be asked to sign the transaction with your Polkadot App. ![RevX App Builder showing the transaction signing prompt](/images/apps/quick-start/revx/revx-11.webp) After signing the transaction, you will see the deployment progress in the terminal. The action is labeled **Publish to .dot**, but the name you receive carries the network's TLD, so on Paseo Next v2 your Product is live under its `.paseo` name. Open it in Polkadot Desktop, or on Polkadot Web at `https://.paseo.li` in any browser. ## Where to Go Next
- **Build Guides** --- Set up the local dev loop, then add capabilities to your Product: signing, on-chain reads, decentralized storage, off-chain pub/sub, and local persistence. [→ Open Build Guides](/apps/build/)
