The Rich Text editor is the default canvas type in ZeroTwo. Powered by BlockNote, it gives the AI a fully formatted document to write into — complete with headings, lists, tables, code blocks, and more. When you ask ZeroTwo to write a document, draft a report, compose an email, or produce any long-form content, this is the editor that opens.

What the AI Writes Here

ZeroTwo uses the Rich Text editor to produce any structured document:
  • Reports and analysis — market research, performance summaries, technical writeups
  • Business documents — proposals, project briefs, meeting notes, SOWs
  • Articles and essays — blog posts, opinion pieces, research summaries
  • Emails and correspondence — professional emails, follow-ups, announcements
  • Documentation — API docs, user guides, onboarding materials, READMEs
  • Templates — any document structure you want to reuse
Prompts to try:
  • “Write a product requirements document for a mobile app”
  • “Draft a job description for a senior software engineer”
  • “Create a weekly status report template with sections for wins, blockers, and next steps”
  • “Write a blog post about the future of AI in healthcare”
  • “Draft a professional email declining a vendor partnership”

Formatting Reference

The Rich Text editor supports a complete set of formatting options. The AI applies these automatically, and you can apply them manually via the toolbar or keyboard shortcuts.

Text Styles

StyleKeyboard ShortcutUse Case
BoldCmd/Ctrl + BKey terms, labels, emphasis
ItalicCmd/Ctrl + ITitles, foreign terms, light emphasis
StrikethroughRemoved or deprecated content
Inline codeCmd/Ctrl + EVariable names, commands, file paths

Headings

Three heading levels structure the document hierarchy:
  • H1 — Document or page title. Use once per document. Markdown shortcut: # at the start of a line.
  • H2 — Major sections. Markdown shortcut: ##
  • H3 — Subsections within a major section. Markdown shortcut: ###

Lists

  • Bullet lists — Unordered items, features, options
  • Numbered lists — Sequential steps, ordered instructions
  • Nested lists — Sub-items under any list item. Indent with Tab, outdent with Shift+Tab.

Tables

Insert tables for structured comparisons or data grids:
  • Add or remove rows and columns via the table toolbar that appears on hover
  • Cells support inline formatting (bold, italic, inline code)
  • The AI can populate table data directly based on your prompt
Example prompt: “Add a table comparing React, Vue, and Angular across learning curve, performance, and ecosystem size”

Code Blocks

Full code blocks with syntax highlighting for major languages. These are distinct from the dedicated Code editor canvas — use them for short snippets embedded within a larger document.

Image Embeds

Embed images by URL directly into the document body.

Slash Commands

Type / anywhere in the Rich Text editor to open the block command menu. Insert any block type without leaving the keyboard:
Slash CommandInserts
/h1Heading 1
/h2Heading 2
/h3Heading 3
/bulletBullet list
/numberedNumbered list
/tableTable
/codeCode block
/imageImage embed
/dividerHorizontal rule
Slash commands work both when you are editing manually and when the AI pauses mid-generation. Insert a block structure, then ask the AI to fill it in.

Inline AI Edits

You do not have to resend a message to revise a passage. Select any text inside the canvas and an inline toolbar appears above the selection.

A small toolbar appears above the selected text with preset actions and a free-text input.

Choose a preset or type your own instruction

  • Rephrase — rewrite in different words, same meaning
  • Expand — add more detail and depth
  • Make shorter — condense without losing key information
  • Fix grammar — correct grammar and punctuation
  • Change tone — adjust to formal, casual, confident, friendly, etc.
  • Translate — convert to another language
  • Or type any custom instruction: “Make this sound more authoritative”

ZeroTwo edits in place

The selected text is rewritten. Everything else in the document stays unchanged.

Undo and Redo

The Rich Text editor uses BlockNote’s native history. All changes — whether made by the AI or by you manually — are tracked in a single undo stack.
  • Undo: Cmd/Ctrl + Z
  • Redo: Cmd/Ctrl + Shift + Z
Undo history is per-session. Refreshing the page clears the undo stack, though the document content itself is saved.

Exporting Rich Text Documents

Click the Export button in the canvas toolbar (top-right of the canvas panel) to export your document.
Exports a formatted PDF preserving all headings, tables, lists, and code blocks. Best for sharing with stakeholders who need to read but not edit the document.

Tips for Best Results

Be specific about document structure. Instead of “write a report on AI trends,” try “write a 5-section report on AI trends with an executive summary, three trend sections (productivity, creativity, automation), and a conclusion with recommendations.” The AI follows explicit structure closely.
Iterate with follow-ups. After the AI writes the document, keep the canvas open and send follow-up messages: “Expand the second section,” “Add a comparison table for cloud providers,” “Make the introduction more concise and punchy.”
Use inline edits for final polish. Once the document is close to final, use inline selection edits to refine individual paragraphs rather than regenerating the entire document.
Export to DOCX for collaboration. If others need to edit the document, DOCX is the most compatible format. Use PDF for final, read-only distribution.
