You’re basically correct — Grammarly doesn’t work in Collabora Online because the document text isn’t standard editable HTML.

In Collabora Online (including CODE), the visible text you see in Writer is rendered onto a **canvas** element. That means there’s no actual DOM text nodes for Grammarly (or similar browser-based grammar checkers) to “see” and analyze. All text editing happens through a server-driven model, not through the browser’s native input fields.

Because of this design:

- Grammarly’s extension can’t hook into the text to provide underlines or suggestions.
- The built-in spell checker in Collabora Online is server-side, so you can instead add your own dictionaries or enable additional languages there.

If you want grammar suggestions, you’d need to either:

- Use Collabora Online’s own spell/grammar tools (limited grammar support at the moment).
