Interaction Flow Diagram Maker

An interaction flow diagram maker is a tool that lets you visually map the steps, decisions, and outcomes in any process or user interaction. MakeCharts provides a free, browser-based flowchart maker where you add nodes and connections to represent each part of your flow, then export or share the result.

Yes. All core flowchart features - adding nodes, connecting them, changing colors and layout - are free with no sign-up required. Free accounts also include AI credits so you can generate a flow diagram from a text description. Paid plans unlock more AI credits, SVG export, and embed codes.

Type a plain-language description of your process into the prompt field - for example, 'user submits a support ticket, system checks priority, assigns to agent or escalates.' The AI maps this to start, process, decision, and end nodes, draws the connections, and labels everything. You can then edit any part manually.

The flowchart includes four standard node types: Start (entry point), Process (an action or step), Decision (a Yes/No or conditional branch), and End (the exit point). Each type has its own customizable color and can be labeled freely.

Absolutely. The tool is well-suited for mapping user journeys, screen-by-screen interaction flows, and navigation logic. Add a node for each screen or state, connect them with labeled transitions, and use decision nodes for conditional paths like 'logged in vs. guest.'

Yes, with a Plus or Pro plan you get an embed code you can paste into any website, blog, or documentation platform. The embedded diagram renders live, so any updates you make in MakeCharts reflect on your site.

Free users can download the flowchart as a PNG image suitable for presentations and documents. Paid plans add SVG export, which scales to any size without losing quality and is ideal for websites and print materials.

Add a Decision node to your diagram, then create two connections from it - one labeled 'Yes' and one labeled 'No' (or any custom labels you prefer). Each connection leads to a different process node, letting you map conditional logic clearly.

Yes. The auto-layout button arranges all nodes cleanly in your chosen direction: top to bottom, left to right, bottom to top, or right to left. You can also drag individual nodes to fine-tune positioning after auto-layout runs.

Yes. MakeCharts is responsive and works on phones and tablets. For complex interaction flow diagrams with many nodes, a larger screen gives you more workspace, but the core tools are fully accessible on any device.
