Explain code
Ask what a snippet does, how layout works or why a script is failing.
AI Chat
AI assistant
Ask for web-development help inside the Mac app.
The assistant is tuned for HTML, CSS, JavaScript and related site work: explanations, debugging, code review, examples, file edits and cleaner implementations.
OpenAI and Anthropic providers
HTML Designer includes provider code for OpenAI and Anthropic, plus app prompts focused on semantic, accessible and responsive web output.
With a project folder open, assistant edits are confined to the project root, can create or update files, and can write raster image requests from SVG source when supported.
Generate snippets
Create clean HTML, CSS and JavaScript examples for common interface tasks.
Review and debug
Use the assistant for code review, accessibility checks and clearer implementations.
Project context
Attach a bounded project file list and readable source files while skipping heavy directories.
