Does it work with Notion Free, Plus, and Business plans?
Yes. Flowblock uses the standard Notion file upload API which works on all plan tiers.
How do I connect Flowblock to my Notion pages?
After installing, click the Flowblock icon and sign in with Notion — you'll be asked which pages to grant access to. Pick your top-level pages (or an entire workspace section) rather than individual pages: Notion automatically extends that permission to every sub-page underneath, so any new page you create inside them just works without re-authorizing.
How do I authorize a page for Flowblock?
If Flowblock can't reach a page, clicking the Flowblock button (or Edit / Open with Flowblock on an existing block) opens a dialog with a button to the extension popup. There are two things to check:
- The page's workspace is connected. Open the Flowblock popup and confirm the workspace this page lives in appears under Workspaces. If it doesn't, click Connect another workspace and authorize it.
- The page is shared with Flowblock. In Notion, open the page and click the ··· menu in the top-right, then choose Connections → Flowblock.
Tip: granting access at a parent page (or a top-level workspace section) extends to every sub-page underneath, so you only need to do step 2 once per branch of your workspace.
What happens to my drawings if I uninstall the extension?
Your drawings are stored as image blocks inside your Notion workspace. They remain visible even without the extension installed — they're just regular images at that point.
How does version history work?
Pro users get up to 5 previous versions of each drawing, stored directly inside the Notion image block — no separate database or storage required. Open a drawing, click "Version history" in the bottom-left corner, and restore any earlier snapshot with one click.
Can I import existing Mermaid diagrams?
Yes — Flowblock detects Mermaid code blocks on your Notion page, including ones generated by Notion AI, and lets you open them as editable drawings with one click. Free users get up to 5 imports per month (shared with the regular drawing quota); Pro unlocks unlimited imports.
Does Flowblock support draw.io?
Yes — pick the editor when creating a drawing: Excalidraw for quick hand-drawn sketches, draw.io for rigorous technical diagrams. Both save as native Notion image blocks.
How do I edit a drawing after creating it?
Hover over any drawing in Notion — an "Edit" button appears in the corner. Click it to reopen the drawing in its original editor with your full content loaded.
Does Flowblock support dark mode?
Yes — drawings always save cleanly in light mode so they look right for everyone, but you can enable "Match Notion's dark mode" in the extension popup to open the editor with the dark theme automatically.
Is there a Firefox or Edge version?
Chrome support is available now. Firefox and Edge versions are in progress.
What happens if I cancel my Pro subscription?
Your existing drawings stay in Notion untouched. Creating new drawings will be limited to the free tier (5 per month).
Is my Notion data secure?
Drawings are uploaded directly to Notion's own file storage using your Notion access token. We never store your drawing content on our servers.
