Promptax is an AI software engineer. You describe an app in plain English, and Promptax plans it, writes every file (HTML, CSS, JavaScript), and shows a live preview — all in your browser. You keep refining it through chat.
No. Plain English is enough. If you do code, you can inspect and edit every generated file — the agent sees your edits and builds on them.
Landing pages, marketing sites, dashboards, stores, blogs, portfolios, waitlists and other web apps. Output is a complete multi-file static site with a live preview.
Promptax runs an agentic loop: the model plans, calls tools to write files to a real project filesystem, verifies its work, and keeps going until the build is done. You get a running app, not a snippet to wire up yourself.
Promptax supports Anthropic Claude, OpenAI GPT, DeepSeek and any OpenAI-compatible endpoint. A deterministic demo mode is included so you can evaluate the product without API keys.
Yes — Free includes 25 agent credits per month and up to 3 projects. No credit card required.
One credit is spent per agent instruction (each message you send that triggers a build). Typical sessions use 5–15 credits.
The agent pauses and you're prompted to upgrade. Credits reset monthly and your projects are never deleted.
Yes. Cancel from your billing page — you keep access until the end of the period, and your projects stay yours.
You do, completely — on every plan including Free. Export it as a zip and deploy it anywhere.
Previews run in a sandboxed iframe — generated JavaScript cannot access your Promptax session or leave the sandbox.
Yes. Projects are private to your account by default. Nothing is published or shared unless you choose to share it.
