Summary

This AI flowchart generator turns a plain-text list of process steps into a live diagram, no design tool required. Type one action per line, prefix a line with ? for a decision, then Y: and N: for the two branches, and the flowchart updates instantly. It also outputs ready-to-paste Mermaid code for Notion, Linear, or GitHub docs. Free, runs entirely in the browser, no signup, built for ops teams documenting SOPs and slash-command playbooks.

Flowchart generator

Type one step per line. Start a line with ? for a decision, then Y: and N: for the two branches.

Start a line with ? for a decision. Follow it with Y: and N: lines for the two branches. Use Start: and End: to mark the endpoints.

How it works

    
Three rules, one live diagram

    
  

    

      

            
            
Live as you type

            
Every line becomes a box the moment you type it. There is no Generate button and no page reload to wait on.

          

            
            
Real Yes/No branching

            
Prefix a line with ? for a decision, then Y: and N: for the two paths. Both branches merge back into whatever step comes next.

          

            
            
Mermaid code included

            
Copy the equivalent Mermaid syntax and drop it straight into a Notion callout, a Linear doc, or a GitHub README.

          

    

  



    

    
Syntax

    
How the parser reads your text

    
Three line patterns, that is the entire syntax.

    Write one action per line
    
              
    A plain line becomes a process box. Start: and End: mark the two endpoints with a rounded shape.

    Mark a decision with ? then Y: / N:
    
              
    A line starting with ? becomes a decision diamond. The next lines prefixed Y: and N: become the two branches.

    Copy the Mermaid code when you are happy
    
              
    The code block below the diagram updates with every keystroke. Copy it into your own docs whenever the flow looks right.

Built for people who write SOPs, not diagrams

        
CommanderGPT ops teams document deal-review flows, lead-routing rules, and onboarding playbooks in plain text every day. This tool skips the drag-and-drop diagram editor: write the steps the way you already think about them, and get a diagram and a Mermaid export out the other end.

        
  • No account required to use it
  • Works from a plain-text list, not a canvas
  • Mermaid output drops straight into your wiki

Questions ops leads actually ask

    
  

    

      

            Is this AI flowchart generator free to use?
            
Yes. There is no signup and no usage cap. The diagram renders in your browser the moment you type; nothing is metered.

          

            Where does my process text go? Is it stored anywhere?
            
Nowhere. The parsing and rendering run entirely client-side in your browser. Nothing is sent to a server, except an anonymous tool-run beacon with no content and no IP stored.

          

            Can it read a Slack thread or a doc and write the steps for me?
            
No. This is a deterministic parser, not a generative writer: it turns the lines you type into boxes and arrows. You write the steps; the tool handles the layout and the Mermaid export.

          

            What if a decision has more than two outcomes?
            
The current version supports exactly one Yes and one No branch per decision. For a third path, add a second decision right after the first one and route the extra case there.

          

            Does the Mermaid code actually work in Notion, Linear, or GitHub?
            
Yes. It outputs standard flowchart TD syntax. Paste it into a Mermaid code block in Notion or a GitHub README, or into any renderer that supports Mermaid, and it draws the same diagram.

          

            When should I use horizontal layout instead of vertical?
            
Vertical reads best when you are pasting the flow into a doc or a wiki page. Horizontal fits better on a wide screen or a slide when you are walking a team through the steps live.

          

            Can I save or share a diagram I built?
            
There is no server-side save yet. Copy the Mermaid code into your own doc, or keep the plain-text steps somewhere you can paste back in here later; either one rebuilds the exact same diagram.
