DiagramSmith: Flowchart Maker

A flowchart maker that opens and saves .drawio files and Mermaid syntax, and checks flowcharts, swimlanes, activity, state and data flow diagrams for logic mistakes. 29 diagram types, PDF, SVG and PNG export, and every drawing is a file on your device. No account.

FILES THAT MOVE BETWEEN TOOLS • Open any .drawio file and edit it here (all pages, swimlanes and layers kept). • Save as .drawio (Pro): flowcharts, swimlanes, ER, UML, Gantt, timelines, org charts, mind maps, block, network, tree and concept diagrams stay editable shapes; charts, SWOT, RACI, Eisenhower and cycle diagrams become one picture. • Paste Mermaid syntax (flowchart, sequenceDiagram, erDiagram, classDiagram, mindmap) and get an editable drawing; export it as Mermaid again for Markdown and docs. • Export PlantUML text, SVG, PNG up to 4x, a picture PDF (Free) and vector PDF with selectable text (Pro).

A DIAGRAM THAT CHECKS ITSELF Pro adds a check for flowcharts, swimlanes, UML activity and state charts and data flow diagrams. It marks decisions with one way out, unlabelled branches, dead ends, loose shapes, parts that cannot be reached from the start, states with no way out and data flows that touch no process. Each problem is outlined on the canvas with a short tip.

29 DIAGRAM TYPES IN ONE APP Flowcharts and templates, swimlane, data flow, cycle, block and network diagrams, decision trees, UML class, use case, state, activity and sequence, ER with SQL, mind maps, org charts, timelines, Gantt, SWOT, RACI and Eisenhower matrices, pie, line, gauge, Sankey and Venn charts, concept maps and tree diagrams.

TYPE OR DRAG Drag shapes and arrows on the canvas, or type one step per line and watch the drawing follow. Auto layout keeps everything tidy; undo goes back 100 steps.

YOUR WORK IS FILES Every drawing is a .dsmith file in the app. The app makes no network requests: nothing is uploaded, no account, no ads, no tracking.

BUILT FOR PHONES AND TABLETS A sidebar layout on tablets, open files from any app with "Open with" or Share, and share exports or save them anywhere with "Save as".
