About this tool
Create flowcharts with ease and share them with your team.
Flow Chart Maker is a drag-and-drop flowchart canvas that builds diagrams from the eight standard flowchart symbols — terminator, process, decision, input/output, database, document, subprocess and comment — and connects them with directional arrows. Drag a shape from the palette onto the canvas, double-click any node to rename it, then drag from one node's handle to another to draw a smoothstep arrow between them. It is for anyone who needs to map a process visually without learning diagramming software: the canvas ships with a worked example you can study before you start your own.
Open Flow Chart Maker on AltFTool — it loads instantly in your browser.
Paste your code or data sample into the workspace.
Pick the format, conversion, or analysis you need.
Copy the polished result straight back into your project.
Decisions are diamonds, input/output is a parallelogram, storage is a cylinder — the conventional flowchart vocabulary rather than a page of identical boxes.
A diamond exposes outgoing connection points on its bottom, left and right edges, so a yes/no/else split routes cleanly without crossing lines.
Double-click a node, type the label, press Enter — editing happens on the canvas so you keep your place in the diagram.
Each shape carries a fixed meaning: an oval is the start or end point, a rectangle is a process step, a diamond is a decision that splits the path, a parallelogram is input or output, a cylinder is a database or stored data, and a shape with a wavy bottom edge is a printed or generated document. This tool provides all of those plus a subprocess block for a step detailed in its own chart and a comment box for annotations.
Drag from the small circular handle on the edge of one node to a handle on another, and an arrow is drawn between them. Connections come out as smoothstep lines with a closed arrowhead so direction is unambiguous, and the diamond decision node offers three separate outgoing handles for branching.
No. The canvas runs in the browser tab with nothing to install and no sign-in, and the diagram you build stays in the page while you work on it. Because there is no server-side project storage, treat a session as temporary and rebuild or capture the chart if you need it later.
Not directly — this is a classic flowchart editor, so it gives you the eight process symbols and arrows rather than lanes, actors or UML class notation. You can approximate a swimlane by grouping nodes visually, but for formal UML you want a notation-specific tool.
