❓ FAQ

Common questions about HTML Editor

Do I need to install anything to use this editor?+
No installation required. The HTML Editor runs entirely in your browser. Just open the page, and you can start coding or describing what you want to build. No signup needed for basic features.
Can I use the AI to generate complete web pages?+
Absolutely. Describe what you want — e.g., "modern portfolio with grid layout and contact form" — and our AI generates complete HTML/CSS/JS code with responsive design.
Is my code saved or shared with third parties?+
Your code stays in your browser local storage by default. If you choose to save projects to the cloud, we encrypt them. We never train AI on your code or share it.
Does it support JavaScript frameworks like React or Vue?+
The primary focus is vanilla HTML/CSS/JS. For simple React components, you can describe them, but advanced framework features are planned for future updates.
Can I import existing HTML files?+
Yes, paste your code into the editor or upload .html files. The preview will update instantly, and you can use AI to enhance or refactor your existing code.
How accurate is the AI code generation?+
Our AI is trained on millions of modern web components. For common patterns (forms, cards, navigation, pricing tables), accuracy is 95%+. Complex custom designs may need minor adjustments.
Can I build interactive tools like calculators?+
Yes! Describe the tool (e.g., "BMI calculator with imperial and metric options") and the AI generates working JavaScript logic alongside HTML/CSS.
Is there a free tier? What are the limits?+
Free tier includes unlimited manual editing, live preview, 50 AI generations/month, and all templates. Premium removes AI limits and adds team collaboration.
