Real-Time Error Analysis

Errors are shown during the check — once the analysis is run, you can view the error list with explanations of why the issue appears and how it can be fixed. Each error links to the exact place in the code, so you don’t have to search manually.

Error analysis saves time by clearly showing not only where the problem is, but also the most common ways to solve it. This makes it easier to understand the context and decide which solution fits best for your case.

Explanations directly at the place where the error is found, without extra noise.
Helpful hover tips with a simple before/after example.
Compact diff cards that clearly display the exact code change and suggested fix.

Real-Time Code Preview and Error Detection

The preview updates on every keystroke. If something breaks, you’ll see a clear error card with line/column info and a suggested fix.

Switch between mobile / tablet / desktop viewports, check above-the-fold content, and pinpoint what slows down the first paint.

The overlay can be disabled, and console output is folded so it never gets in the way.

Live, iframe environment.
Jump-to-code links for every error.
Concise diagnostics (console, network highlights).

Two-Panel Workspace for Efficient Development

Work side by side: code on one panel, preview or docs on the other.

Compare versions with an integrated diff view and use “copy-back” to bring only the good parts to your source.

In pair mode, cursors and selections are indicated subtly — collaboration without visual noise.

Handy shortcuts for faster editing.
Instant theme switch (light / dark).
Starter layout presets in one click.

Clean and Optimize Code with One Click

One click removes duplicate inline styles, empty tags, bad attributes, normalizes quotes/indentation, and tidies the structure.

“Word-HTML cleanup” understands Office-specific markup and keeps only the semantically relevant parts. Optionally adds a minimal reset/normalize.

After cleaning, you get a short report: how many tags/attributes were removed and an approximate byte savings.

“Soft clean” (conservative) and “Deep clean” (stricter).
Allowlist for classes/attributes you want to keep.
Automatic prettify — consistent indentation and line breaks.

AI-Powered Web Development Topic Library with Live Code

This is your built-in web dev explainer — powered by AI. Just click a topic and get a simple, beginner-friendly explanation of what it does, how it works, and see live code in action you can try right away.

Not in the mood to search through docs or decode tech jargon? We get it. Just pick a topic — like “AJAX Database” or “CSS Flexbox” — and we’ll show you what it is, how it works, and why it matters. No fluff, no popups, just a friendly explanation and live code you can edit and run right here. Whether you’re just getting started or need a quick reminder, this is the kind of help that makes sense right away.

Explain Code (AI)

Explains the selected HTML, CSS, or JS snippet: what it does, how it is structured, and where issues may appear. Returns a plain-text explanation — review and adapt, as AI may simplify things.

Generate Code with AI

Generates small, self-contained snippets (a card, a form, a simple JS function) based on your prompt. Insert them into the editor and preview live. They serve as starting points, not complete solutions.

Live Preview / Run

Renders the current editor content in the browser instantly — no builds or servers needed. Quick way to test markup and small JS logic.

Create & Download HTML

Packages your current content into a plain .html file and downloads it. Useful for quick demos or saving a static version.

HTML Cleaning Tool

Removes Word-HTML clutter, empty tags, and unwanted attributes according to your options. Does not change layout logic — only cleans what you allow.

Emmet Expand

Turns abbreviations into full HTML/CSS (for example ul>li*3). Great for scaffolding markup quickly, then editing the details.

Code Library

Ready-made examples (buttons, layouts, small scripts). Insert and adapt them — they serve as starting points, not final components.

Save / Share

Save your current content and share it via a link. The recipient sees exactly that version. Simple and quick, without complex version control.

Collaboration

Share a link, get feedback, and receive the updated file back. This is not real-time multi-user editing — more like “share → review → edit → return”.

Next-Level HTML Editing

Experience ultra-fast conversion, smart formatting, and seamless Word-to-HTML transformations. Perfect for developers, bloggers, and everyone in between.
