- Clearly mark final/accepting states to improve readability in your DFA diagram generator online output.
- Chat-Based Refinement
- Rename states, adjust transitions, or add notes with simple instructions—useful for iterating on a DFA creation tool online.
- Export-Ready Output
- Download your DFA diagram as PNG, SVG, or PDF for reports, homework, slides, or sharing with teammates.
