Slate: Real-Time AI Collaboration on Code and Docs

Slate is Caiioo's workspace for editing code and documents with the AI. Instead of copying text back and forth, work together in real-time with inline diffs, comments, and version history.

What Slate Can Do

  • Code editing — Write and edit code with syntax highlighting. See exactly what changed and accept/reject changes one at a time.
  • Rich text editing — Create documents with formatting, headings, tables, and lists. Get AI suggestions inline.
  • SVG drawings you can see and refine — Open an SVG (a logo, diagram, or chart) and flip between the source code and a rendered image with one toggle. The AI renders the drawing as it works, sees the result, and iterates—so it can fix a misaligned label or recolor a shape and confirm the change visually in the same turn.
  • LaTeX documents with typeset math — Open a LaTeX document and see a preview with the math properly typeset, while the source stays safely editable in the code view (the preview never rewrites your file). The AI checks the math whenever it edits a LaTeX document and sees errors immediately, so a broken equation gets corrected in the same turn. Pasted LaTeX content is recognized automatically.
  • PDF markup — Ask the AI to draw on a PDF: freehand ink to circle a clause or point an arrow at a figure, notes placed anywhere on the page, and a signature image stamped where you want it. The marks are written into the PDF itself, so they're still there when you download it and open it anywhere else. (A stamped signature is a visual mark only — it carries no identity verification and is not a legally binding e-signature.)
  • Version history — Go back to any previous version. See who changed what and when.
  • Comments — Leave notes on specific parts of your code or document.

How to Use Slate

The AI opens Slate automatically when you ask for code or document creation:

  • "Write a Python script that scrapes product reviews"
  • "Draft a blog post about machine learning"
  • "Create an HTML page with a contact form"
  • "Edit this document and improve the tone"

When the AI opens a Slate, you can:

  1. Read the code or document — It's displayed with full formatting
  2. Review changes — If the AI proposes edits, see the diffs highlighted inline
  3. Accept or reject changes — Click checkmark to accept, X to reject (one change at a time)
  4. Make your own edits — Directly edit the code or text
  5. Ask for more changes — "Add error handling to this function" or "Make this more concise"
  6. View history — Click "History" to see all edits and revert if needed

Code Features

  • Syntax highlighting for Python, JavaScript, TypeScript, Java, C++, CSS, HTML, SQL, and more
  • Line numbers and bracket matching
  • Inline diffs — See exactly what changed, line by line
  • Per-change accept/reject — Granular control over each edit
  • SVG code ↔ view toggle — For SVG drawings, switch between the raw markup and a rendered preview with a single click; edit the code and watch the picture update

Rich Text Features

  • Formatting toolbar — Bold, italic, links, lists, tables
  • Headings and blocks — Organize with structure
  • Comments — Leave notes without modifying the text
  • Tracked changes — See additions, deletions, and modifications with colored highlights. Accept or reject one change at a time, all at once, or select a region and use "✓ Sel" / "✗ Sel" to accept or reject every tracked change inside your selection—just like selecting a paragraph in Word.
  • Spreadsheet tracked changes — Spreadsheet (.xlsx) edits support cell-level tracked changes too. The AI proposes changes cell by cell, and you accept or reject each one just like in a document.
  • Find and replace — Search across the document and replace matches

Review Changes in a Word Document

  1. Open the .docx file in Slate
  2. Click Track if you want your own edits recorded as proposed changes, then enter your name in Your name
  3. Use ↑ and ↓ to move between changes
  4. Use ✓ or ✗ to accept or reject the current change, or select part of the document and use ✓ Sel or ✗ Sel
  5. Download the document as Word when you're ready to continue in Microsoft Word

When you download the document as Word, your tracked changes and comments are written into the .docx file itself, so Word opens them as native tracked changes and keeps each author's work separate. They also survive uploading the file to Caiioo again.

Tips

  • You can edit while the AI is working—changes sync
  • Version history keeps every edit. You can't lose anything
  • Point the AI at any document by pasting its Slate link into the chat ("this is the file I want to update: …")—it resolves to the right document, even if the link came from a different conversation
  • Export in the format that fits your workflow: Word (.docx), PDF, HTML, Markdown, rich text (.rtf), CSV for tabular data, or the document's native format
  • A Word document downloads with its pending tracked changes and comments intact. Markdown and rich-text exports read as the finished document, without deleted text included as live content
