# FlowSimp

> Free online flowchart maker, flowchart generator, and whiteboard. Draw in the browser — no signup, no install, no watermark.

FlowSimp is a free browser diagram tool at https://flowsimp.com/. Paste text or Mermaid to generate a flowchart, or draw one by hand. Export PNG or SVG, or share a read-only /v/<id> link. Older compressed /view# links still open. The long pages below answer one query each, include a worked example that imports in FlowSimp, and show a Last updated date. That date is also dateModified on the page and lastmod in the sitemap. Full notes: https://flowsimp.com/llms-full.txt

## Common questions

- **What is the best free flowchart maker?** For a flowchart in a browser tab, FlowSimp is completely free to use — no sign-up required. It draws rectangles, diamonds, and circles, imports a Mermaid flowchart or an indented outline, and exports PNG or SVG with no watermark. It does not open Visio .vsdx files and it has no live cursors. https://flowsimp.com/flowchart-maker
- **Is FlowSimp free?** Yes. FlowSimp is completely free to use — no sign-up required. Exports have no watermark.
- **Do I need an account?** No. Guest mode works. Optional Google sign-in saves boards across sessions.
- **Can I turn text into a flowchart?** Yes. Paste an outline or Mermaid at https://flowsimp.com/text-to-flowchart. Flowchart and graph syntax also converts at https://flowsimp.com/mermaid-to-flowchart. Sequence, class, state, ER, Gantt, pie, git, and mindmap diagrams are not imported.
- **How do you make a flowchart?** Name one process, list the steps, mark each decision, then draw. Guide: https://flowsimp.com/guides/how-to-make-a-flowchart. Symbols that the toolbar actually has: https://flowsimp.com/guides/flowchart-symbols
- **What is a process map?** A flowchart that also shows who does each step. The swimlane template is a refund across Customer, Support, and Finance. https://flowsimp.com/process-map-maker
- **What is the whiteboard?** Pen, eraser, and text. Six colors. The stroke thickens and thins along its length. It does not read stylus pressure and it is not a live multiplayer board. https://flowsimp.com/online-whiteboard
- **Icon:** https://flowsimp.com/icon-512.png is a 512×512 PNG.
- **Can I export?** Yes, as PNG (2×, white background) or SVG.
- **What is stored?** Guest diagrams stay in the browser. An optional account saves boards in Supabase. Share links are visible to anyone who has them. Analytics is Cloudflare Web Analytics, which is cookieless. Details: https://flowsimp.com/privacy. Contact: hello@flowsimp.com.
