$ describe it, and it gets built

An AI web developer in your browser.

Tell 9x Code what website or web app you want, in plain language. It writes the files while you watch, shows a live preview, and changes anything you ask for. You pay per use from a prepaid rupee balance.

Illustration of the 9x Code workspace. Your own site will look like whatever you describe.

How it works

Describe what you want

Watch it get built

The assistant writes real HTML, CSS and JavaScript files. A live preview updates as each file lands, and multi-page sites link together.

Change it by chatting

Ask for a new section, a different colour, another page. You can also open the Code tab and edit any file yourself.

Take the files with you

Download the whole project as a .zip and host it anywhere. Your balance shows what each reply cost.

What it does

Works on your phone or computer, in any modern browser.

Builds websites and web appsLanding pages, portfolios, small business sites, calculators, to-do apps and other front-end tools, from plain HTML, CSS and JavaScript.

Live preview that stays safeThe preview runs in a sandbox that cannot reach your 9xAI account.

Remembers each projectEvery project keeps its files and its conversation, so you can come back tomorrow, on another device, and carry on.

Claude first, OpenAI tooDefaults to Claude Sonnet. Pick another model per project from the menu. If a provider is unavailable, 9x Code retries on the other one.

Pay only for what you useA prepaid ₹ balance charged per token. Every reply shows its cost, and the dashboard shows spend by day, model and project.

Pricing

Pay as you go from a prepaid balance, with no subscription. New accounts get ₹50 free, once. Top up from ₹100 to ₹50,000 on the 9xAI dashboard. Prices include GST.

Price per million tokens in rupees
Model	Input per 1M	Output per 1M
Claude Sonnet 4.6 default	₹501	₹2,507
Claude Haiku 4.5	₹167	₹836
Claude Opus 4.6	₹2,507	₹12,534
OpenAI GPT-4.1	₹334	₹1,337
OpenAI GPT-4o	₹418	₹1,671
OpenAI GPT-4.1 mini	₹67	₹267

A bigger site costs more than a small change, and the cost of every reply is shown under it. Repeated context is cached, so cached input on Claude models costs a tenth of the input price. Prices can change; the app always shows what applies to you.

Your data

What is sent to the modelYour messages and your project's files are passed to the model provider: Anthropic for Claude models, OpenAI for OpenAI models or when Claude is unavailable.
