A focused editor with the Source panel never far.
Markdown and WYSIWYG side-by-side. Autosave every keystroke. Version history with one-click rollback. A Source panel that never leaves your side.
Why this matters
Most editors are either Markdown-only (hostile to non-engineers) or WYSIWYG-only (locks you out of structured content). Neither gives you access to your research without leaving the editor — which is exactly when you need it most.
Four steps, no friction.
- 1
Open a Topic
Tap any day on the Calendar to open its Topic. The editor opens with the Topic’s outline, sources, and AI agent config already attached.
- 2
Write in Markdown or rich text
Toggle between Markdown and WYSIWYG on the same document. Both render to the same canonical HTML.
- 3
Pull in a source
Open the Source panel without leaving the editor. Drag a quote into your draft — it cites itself automatically.
- 4
Roll back if needed
Every save is a version. Compare two versions side-by-side, restore an earlier draft with one click.
What you get out of the box.
- Markdown and WYSIWYG on the same document
- Autosave every 2 seconds — never lose a sentence
- Per-section version history with diff view
- Inline source citations that link back to the Source Library
- Slash commands for headings, lists, quotes, callouts, and code
- Distraction-free Zen mode on mobile and desktop

Sections, not pages.
The problem. A 4,000-word article in a single editor buffer is fragile.
The Contents Lab way. A Topic is composed of Sections. Each Section is its own editor buffer with its own version history. Reorder Sections by drag, hide one without deleting it.
- Each Section has a status: draft, final, archived
- Section-level word count and reading time
- Compare any two Section versions side-by-side
The Source panel is always one tap away.
The problem. Leaving the editor to fetch a quote is a guaranteed context switch.
The Contents Lab way. The Source panel slides in from the right edge — never a full page navigation. Drag a quote or fact into the editor and it cites itself.
- Filter sources by tag, type, or recency
- Full-text search across the entire Project Source Library
- Insert source as footnote, inline citation, or blockquote
