Step-by-step guides for getting the most out of DocuShark — from your very first shape to diagrams you build with a whole team. No setup headaches, no jargon.

Where would you like to start?
Jump straight to whatever you came here to do.
Draw & diagram
Get hands-on with the canvas — drawing tools, smart connectors, and ready-made shape libraries for any kind of diagram.
Write & collaborate
Mix rich text with your diagrams, invite your team to edit live, and send the finished thing anywhere you need it.
Why people love it
A canvas that bends around how you think
Words and drawings live on one page, and the workspace reshapes itself around whatever you're doing right now.
Docs and diagrams, one page
Write a how-to and sketch its diagram right beside it — your notes and an endless drawing canvas in the same document. No jumping between apps, no screenshots that go stale.
One document, no tool-switchingA workspace that flexes
Four ready-made layouts reshape the screen around the task — a calm, clean page for a quick note, or a full diagramming cockpit when you're mapping out something big.
Four ready-made layoutsLet AI lend a hand
Point your favourite AI assistant at a document and ask it to help. Its changes arrive as a clear, reviewable suggestion you can accept or reject — never a surprise rewrite.
You approve every editIn the box
Everything you'd expect, and the parts no one else ships
Real-time collaboration
Work on the same diagram together, live. See everyone's cursors as they move, and share with a single link.
Offline-first desktop
A desktop app that works with no internet at all — your documents live on your own computer, ready whenever you are. Free, forever.
Files live with your docs
Embed PDFs, spreadsheets, and datasets right next to the canvas, pinned wherever you want them.
Shape libraries
Flowchart, UML, ERD, and cloud shapes out of the box — plus custom libraries you build, share, or import.
Stays fast on huge diagrams
Thousands of shapes stay smooth and responsive. DocuShark keeps up even when your diagram grows enormous.
Import & export
Bring diagrams in from Mermaid, draw.io, PlantUML, and Excalidraw. Send them out as PNG, SVG, PDF, or Markdown bundles.
