Flowblock - Draw in Notion

Create, edit, and store drawings and diagrams as native Notion blocks.

The drawing tool built for Notion. ----- Flowblock lets you create, edit, and store hand-drawn diagrams, wireframes, and sketches as native Notion image blocks — without leaving your workspace. No embeds, no external links, no dead iframes. Your drawings live inside Notion and travel with your pages. How it works ----- 1. Click "Add drawing" — a floating button appears at the bottom-right of any Notion page. Click to open the editor in a modal. 2. Draw anything — use the full Excalidraw editor (or draw.io for technical diagrams): freehand, shapes, arrows, text, and hand-drawn style that looks great in any doc. 3. Save to Notion — your drawing appears instantly as an inline image block. Hover over it any time to re-edit — content loads back exactly as you left it. What you can draw ----- - Flowcharts and decision trees - System architecture and service diagrams - UI wireframes and mockups - Mind maps and org charts - Freehand sketches and whiteboard-style notes - Technical diagrams (draw.io) Features ----- - Full Excalidraw editor — the beloved hand-drawn style, embedded directly in your browser. - Native Notion blocks — drawings live as real Notion image blocks, not external embeds. They survive uninstalling. We never store your content on our servers. - [COMING SOON] draw.io editor — pick the right tool: Excalidraw for sketches, draw.io for rigorous technical diagrams. - Edit any time — hover over any drawing in Notion to reopen it in its original editor. - Dark mode — match Notion's dark theme automatically. Pro features ----- - Version history — every save snapshots the last 5 versions inside the drawing itself. Restore with one click. - Mermaid import — detect Mermaid code blocks on your page (including ones from Notion AI) and open them as editable drawings. - Unlimited drawings — free plan includes 5 drawings per month; Pro removes the cap. Pricing ----- - **Free forever** — 5 drawings per month, both editors, native Notion blocks. - **Pro** — $4.99/month or $49.99/year (2 months free).
