WHY PROMPTAX
Everything between your idea and a running app, handled.
Describe your app in plain English. Promptax plans the structure, writes every file, and wires it together.
Watch your app appear as files are written. Click around, test it, and ask for changes in chat.
Every file is inspectable, editable and exportable. It is your code — take it anywhere.
'Darker hero', 'add a pricing tier', 'write real testimonials' — each message is a build step.
Landing pages, dashboards, stores, blogs — the agent knows the patterns and applies them cleanly.
Generated code runs in a sandboxed preview. Nothing touches your machine until you export it.
HOW IT WORKS
One sentence is enough. 'A booking page for a yoga studio' becomes a plan instantly.
The agent writes files in real time — you see every create, edit and decision as it happens.
Refine in chat until it's right, then export the code or keep iterating. It's yours.
