How to Make a Flowchart in Notion (2025)

If you want to make a flowchart in Notion, you have two reliable paths:

Make a Notion flowchart with Mermaid (code block rendering)
Make a Notion flowchart by embedding external diagram tools (Miro, Lucidchart, diagrams.net/draw.io, Excalidraw, Mermaid Chart)

This step-by-step guide explains both approaches, highlights pros/cons, and links to the official Notion Help Center. All steps are verified.

Option 1 — Make a Notion flowchart with Mermaid (code blocks)

Best for: fast, lightweight flowcharts directly inside Notion pages.

What you need to know

Notion renders Mermaid diagrams when you select the mermaid language in a code block (officially announced by Notion on Dec 23, 2021). See: Notion Releases — “Create flowcharts & diagrams in code blocks (Mermaid)”: https://www.notion.so/pt-br/releases/2021-12-23
Official docs for code blocks: Notion Help — Code blocks: https://www.notion.com/help/code-blocks
Tip: In Notion’s code block, you can switch the top-left dropdown from Code to Preview/Split to see a live Mermaid render while editing (per Notion’s announcement).

Steps

Add a code block

Type /code and press Enter (or click the + on a new line and choose Code)

Set language to Mermaid

Click the language label on the code block and select mermaid

Paste your Mermaid flowchart code

flowchart TD
  A([Start]) --> B[Collect requirements]
  B --> C{Is scope clear?}
  C -- Yes --> D[Design flow]
  C -- No --> B
  D --> E[Implement]
  E --> F([Done])

Tweak the diagram

Edit node labels (text in brackets) and transitions
Use subgraphs, styles, or direction hints (TB, LR, TD)

Pros

Native Notion feeling, no external accounts
Easy to version as text; great for documentation and wikis

Cons & caveats

Advanced layout control is limited compared to dedicated tools
PDF export/print of Mermaid blocks may vary by environment; if fidelity matters, consider exporting from an embedded diagram tool or take a high-resolution screenshot beforehand (community-reported behavior)

Option 2 — Make a Notion flowchart by embedding external tools

Best for: complex flowcharts, auto‑layout, collaboration, and export control.

What you can embed (verified)

Notion supports embedding content from 1,900+ domains via Iframely. Commonly embedded tools include Miro, Lucidchart, diagrams.net/draw.io, Excalidraw, YouTube, etc. Official docs: Notion Help — Embeds, bookmarks & link mentions: https://www.notion.com/help/embed-and-connect-other-apps

Steps (generic)

Copy the public share link or embed link from your diagram tool (e.g., Miro board, Lucidchart share link, draw.io published URL)
In Notion, type /embed (or paste the URL directly)
Choose Create embed or accept the preview
Resize the embed block to fit your page layout; arrange into columns as needed

Tool‑specific notes

Miro: great for infinite canvas, team collaboration, and quick workshops
Lucidchart: rich diagram types, enterprise sharing & export options
diagrams.net (draw.io): free and powerful, supports local or cloud storage
Excalidraw: hand‑drawn style diagrams; fast to sketch flows
Mermaid Chart (web editors): generate Mermaid flowcharts and embed the live preview link

Pros

Best visual quality and auto‑routing; robust export to PNG/SVG/PDF
Real‑time collaboration features (Miro/Lucid/Lucidspark, etc.)

Cons & caveats

Some embeds require viewers to be signed in to the external tool
If a site disallows embedding, Notion will show a “Failed to Load” error (see Notion Help)
Privacy note: Embeds use Iframely; viewers’ IPs may be shared with the embedded app for rendering (per Notion Help)

Which Notion flowchart method should you choose?

“I want the quickest way inside Notion”: choose Mermaid code block
“I need polished, complex flowcharts with export control”: choose Embed (Miro, Lucidchart, draw.io)
“I want text‑to‑diagram and versioning in Git”: use Mermaid (inline), or generate in an external Mermaid editor and embed

Practical examples

Mermaid example for a Notion flowchart (copy/paste into a mermaid code block):

flowchart LR
  S([Start]) --> P1[Open Notion page]
  P1 --> P2[/Type "/code" and select Mermaid/]
  P2 --> P3{{Add nodes and edges}}
  P3 -->|Preview| P4[Adjust labels and directions]
  P4 --> E([Publish])

Embedding a draw.io/diagrams.net flowchart in Notion (generic)

In diagrams.net, share or publish the diagram to get a link
In Notion, paste the URL and select Create Embed (or type /embed and paste)
Resize the embed block; organize with columns for your page design

FAQ: Notion flowcharts (verified)

Does Notion support Mermaid for flowcharts?
- Yes. Use a code block with the mermaid language to render a Notion Mermaid flowchart (flowchart, sequence, class, etc.). Official code block doc above; Mermaid rendering is widely used and community‑verified.
Can I embed Miro/Lucidchart/draw.io into Notion?
- Yes. Use /embed and paste the share URL. If the site requires sign‑in, viewers may need access. If a site blocks embedding, you’ll see a load error.
How do I export a Notion flowchart?
- For Mermaid: export reliability varies across print/PDF; many teams use screenshots or external Mermaid editors for high‑fidelity exports. For embedded tools, export directly in the tool (PNG/SVG/PDF) for the best results. See Notion Help — Export your content: https://www.notion.so/help/export-your-content

Conclusion: The best way to make a flowchart in Notion

If you need a lightweight, versionable flowchart, Mermaid code blocks in Notion are excellent. For complex flowcharts with auto‑layout and rich export, embed a professional diagram tool (Miro, Lucidchart, diagrams.net). Either way, your Notion flowchart stays close to the context of your docs, wikis, and project pages.
