How it works

From paste to AI edit in three steps.

1
Paste or drop your HTML
Open the editor and paste any HTML file, drop a folder, or start from a template. Your code appears in the Monaco editor with live preview on the right.
2
Click any element to select it
Activate AI mode with the ✦ button in the toolbar. Hover over your live preview — sections, buttons, headlines, images — and click the one you want to change.
3
Describe the change in plain English
Type what you want: "Make this button teal and larger", "Rewrite this section copy to be more concise", "Add a gradient background". The AI makes the edit live, streaming the diff as it goes.
4
Deploy with one click
Happy with the result? Hit Deploy. Your updated site is live at your htmlhost.co URL in under 3 seconds — no build step, no config.
Features

Everything you need from an AI editor.

Click-to-select element editing
Hover over any element in the live preview and click to target it for AI editing. The AI receives the element's full context — tag, classes, position, and parent — for accurate edits.

Streaming live preview
Watch the AI rewrite your HTML in real time. The preview iframe updates as tokens stream in, so you see the change taking shape before it completes.

Full-page and scoped edits
Ask for element-level tweaks or full-page rewrites. The AI automatically determines the right scope — a targeted edit for small changes, full page context for structural work.

FAQ

Frequently asked questions.

Is the AI HTML editor free to use?
Yes. Free accounts get 10 AI edits a day with the built-in AI, at no cost. You can also bring your own API key from OpenAI, Anthropic, or Google for unlimited edits — your key is saved only in your browser, and when you use it, it passes through our proxy to the provider without being stored or logged.
Which AI models can I use?
The editor offers the latest models from OpenAI (GPT), Anthropic (Claude) and Google (Gemini), and adds new ones as they're released. Switch between them freely. Bring your own API key or use the built-in htmlhost AI credits.
How does element selection work?
Click the AI cursor icon in the editor toolbar to enter AI mode. Hover over any element on your live preview — sections, headers, buttons, images — and click to select it. The editor sends the selected element's HTML, its parent context, and your instruction to the AI. Only the relevant fragment is edited, keeping your surrounding code intact.
Can it edit multi-page projects?
Yes. htmlhost.co supports multi-page projects with a file tree. The AI editor works per-page, editing the active file. You can switch between pages in the tab bar and run AI edits on each independently.
What is BYOK (Bring Your Own Key)?
BYOK lets you paste your own API key from OpenAI, Anthropic, or Google directly into the editor. Your key is saved only in your browser; when you use it, it passes through our proxy to the provider without being stored or logged. This gives you unlimited AI edits at your own API cost, with no monthly cap.
Does the editor work with existing HTML files?
Yes. Paste any HTML, drop a file, or import a multi-file project. The AI editor works on whatever you bring in. It also handles vanilla HTML with inline CSS and JS — no framework required.
