Own the technical document from draft to publish
Write long documents, ask AI for reviewable help, collect focused SME feedback, create technical visuals, and publish from one Markdown source.

Long-document authoring
Stay oriented inside the document, not around it
Keep Markdown source, rendered preview, structure, metadata, and lint feedback in one focused surface built for guides that grow over time.
- Split source and live preview
- Generated table of contents and heading navigation
- Frontmatter, linting, imports, and portable exports

Reviewable contextual AI
Ask for help without surrendering the draft
Use Ask, Edit, and AI Review with the open document in context. Proposed edits remain visible and advanced Agent plans require approvals.
- Document-aware questions and rewrites
- Inline diffs before an edit lands
- AI findings can become ordinary review items

SME review
Keep feedback attached to the exact claim
Invite subject-matter experts to the live draft and work through focused comments, suggestions, replies, assignments, and resolution.
- Read or write permissions
- Comments, suggestions, and highlights
- Replies and resolution in the editor

Technical visuals
Create the diagram while the context is still open
Generate a photo, diagram, chart, or animation, or keep the source reviewable with Mermaid, Graphviz, Markmap, tables, and code images.
- Generate Visual for photos, diagrams, charts, and animations
- Diagrams-as-code with live preview
- Visual table editing and code images

Publishing and recovery
Publish the source you reviewed—and recover it later
Send the same Markdown to the destination that needs it, keep automatic history underneath, and export a portable copy at any time.
- GitHub, WordPress, Ghost, DEV, Hashnode, X Articles, and webhooks
- Gists, S3, hosted links, and portable exports
- Automatic history with compare and restore
