Embedding Custom-Editor Files

A markdown document can render other workspace files inline as live frames. Drop a link to a file like .mockup.html, .excalidraw, .datamodel, .csv, or any other custom-editor file on its own line and Nimbalyst upgrades it into an embedded editor in WYSIWYG view.

A markdown spec with a mockup and an Excalidraw diagram embedded inline.

How it works:

• Type @ to pick a file. If the file is a supported custom-editor type and the link ends up alone in its own paragraph, it auto-upgrades to an inline embed.

• You can also paste a normal markdown link like [my mockup](./docs/api.mockup.html) on its own line.

• The embedded frame is the real editor for that file. Edit it in place and the change saves back to the file on disk.

• Multiple users see embedded edits stream in live when the document is shared.

Switch to raw Markdown view (the three dots at the top right) to see the underlying link. The link round-trips: write a link in raw view, switch to WYSIWYG, and it becomes a live frame.

AI Editing in Shared Collaborative Documents

When you are editing a shared document in collaboration mode, the right-pane chat sees and edits the active document the same way it does in Files mode. Edits route through Yjs, so other connected users see them stream in live. The familiar accept/reject bar appears for pending AI edits, just like in single-user editing.

You don't need to do anything special to turn this on — open a shared document, ask the agent to edit it, and the changes flow into the document for everyone in the session.

Anchor Links to Headings

Clicking a Markdown anchor link like [Section](#section) in a Lexical document scrolls the document to the matching heading.

Export to PDF

Markdown documents export to PDF with the document title and an outline generated from your headings. Exported files are bookmarked at each heading and the title shows up in PDF readers.
