Flowchart Maker & Diagram Tool
Create flowcharts and diagrams online. Use our intuitive drag-and-drop editor to map processes, algorithms, or organizational structures.
How it works
Define your process steps and decision points. Each step becomes a shape (rectangle for processes, diamond for decisions, oval for start/end). Connect them with arrows showing flow direction.
Arrange shapes to show the logical sequence. Decision diamonds branch into multiple paths based on yes/no or multiple conditions. The flowchart visualizes the complete process from start to end.
Flowchart symbols:
- Oval: Start and end points
- Rectangle: Process or action steps
- Diamond: Decision points (yes/no branches)
- Arrow: Flow direction
- Parallelogram: Input/output operations
The flowchart renders with clear visual hierarchy. Follow arrows from start to end to understand the process. Export for documentation, training, or process improvement.
When You'd Actually Use This
Software algorithm documentation
Map out program logic before coding. Developers understand flow before implementation. Technical specifications include flowcharts for clarity.
Business process mapping
Document how work flows through departments. Identify bottlenecks and redundancies. Process improvement starts with understanding current state.
Customer service procedures
Show agents how to handle different scenarios. Decision trees guide consistent responses. New hires learn procedures faster with visual aids.
Troubleshooting guides
Create diagnostic flowcharts for equipment or software. Users follow branches based on symptoms. Reduces support calls with self-service troubleshooting.
Approval workflow visualization
Map document or purchase approval chains. Employees understand who approves what. Automation systems use flowcharts for workflow configuration.
Educational concept explanation
Teachers show decision processes in subjects like biology (diagnosis) or math (problem solving). Students grasp logical sequences visually.
What to Know Before Using
Start with a clear beginning and end.Every flowchart needs defined start and end points. Multiple ends are okay for different outcomes. Undefined endpoints confuse readers.
Decision points must be binary or exhaustive.Yes/no decisions are clearest. For multiple outcomes, ensure all possibilities are covered. Missing branches leave the process incomplete.
Flow generally goes top to bottom, left to right.Follow reading conventions for intuitive flow. Upward or backward arrows indicate loops. Minimize crossing arrows for clarity.
Keep text in shapes concise.Use action verbs for process boxes. Decision text should be clear questions. Long text makes flowcharts hard to read.
Pro tip: Use swimlanes (horizontal bands) to show who does each step. Different departments or roles in separate lanes clarifies responsibility.
Common Questions
How detailed should flowcharts be?
Match detail to audience. Executive summaries show major steps only. Training docs include all decisions. Create multiple levels if needed.
What software creates flowcharts?
Many options exist: Lucidchart, Visio, draw.io, and this tool. Choose based on collaboration needs, integration, and budget.
Can flowcharts have loops?
Yes, arrows can point back to earlier steps. This shows iteration or retry logic. Label loop conditions clearly to avoid infinite loop confusion.
How do I validate a flowchart?
Walk through with actual cases. Every path should lead somewhere. No dead ends except legitimate termination points. Have process owners review.
What's the difference from mind maps?
Flowcharts show sequential processes with decisions. Mind maps show hierarchical ideas radiating from a center. Different purposes, different structures.
Can I add notes or annotations?
Yes, use callout boxes or comments for additional context. Keep them separate from the main flow. Annotations explain without cluttering.
How do I update flowcharts?
Version control your flowcharts. Date each version. When processes change, update the flowchart immediately. Outdated flowcharts cause confusion.
