常见问题
How do I use it?
Paste a roster, choose layout/options, click Generate, then print or download.
Are names stored or uploaded?
No. Everything runs locally in your browser. URLs are settings-only by default.
How do I specify avoid-adjacency pairs?
In Advanced, add one pair per line as “A,B”. For grid, adjacency is up/down/left/right (diagonal optional).
Can I fix seats for specific people?
Yes. Use “Name @ r,c” for grid or “Name @ T2-S3” for tables in Advanced.
What is seeded mode?
Seeded mode makes results reproducible with the same seed. It is not intended for secrecy.
Any printing tips?
Use landscape if needed, adjust scale, and consider larger rows/columns for readability.
