How to use it

  1. Pick the closest template: inquiries, returns, purchase approval or order handling.
  2. Reword the steps for your company; write decisions, loops and swimlanes from the cheat sheet below.
  3. Download SVG for SOPs and slides or PNG to share; a share link lets others keep editing.

Frequently asked questions

Why draw a flowchart from text instead of dragging boxes?

Changing the process means editing one line while arrows and layout rearrange themselves; the text drops straight into SOPs, docs and Git, so every change is visible.

How do I write decisions, loops and swimlanes?

Decisions are if (condition?) then (yes) … else (no) … endif, loops use repeat … repeat while (condition), and a swimlane starts with |Team|, after which steps belong to that team. The cheat sheet below lists the rest.

Can I use it in Visio, PowerPoint or Word?

Yes. SVG is vector, so it stays sharp in PowerPoint, Word or Visio; PNG exports at 2× resolution for chat and email.

Is my flowchart stored or published?

No. For the preview the source is rendered on this site's server in sandbox mode and discarded at once; a share link carries the compressed source, visible only to people you send it to.

Flowchart maker practical guide and common questions

What does a Flowchart maker do?

Write the process in PlantUML activity syntax — steps, decisions (if/else), loops (repeat), parallel branches (fork) and swimlanes (a team name between vertical bars) — rendered to SVG on this site's server in sandbox mode and discarded afterwards.

Who is this for, and when is it useful?

Sales, order follow-up, purchasing and office teams writing SOPs, job manuals and approval rules who need inquiry handling, returns or purchase approval drawn clearly for colleagues.

How do I use this Flowchart maker?

Pick the inquiry, returns or purchase template, reword the steps for your company, write decisions and swimlanes from the cheat sheet and export SVG for documents or slides.

How should I interpret the results?

Layout follows the order of the text, so boxes cannot be placed by hand as in drag-and-drop tools; split very long processes into several charts.

Where is the work performed, and which services receive data?

For the preview the flowchart source goes to this site's server and is rendered without being stored or logged; a share link keeps the source inside the link itself.
