Weighted draw tool
Edit your list and settings, then draw. Auto draw keeps results fresh while you tweak inputs.
Paste items in any of these formats: item, 2 · item 2 · item | 2. Lines starting with # are ignored.
Use a period for decimals, for example 1.5. Weight 0 is never selected; positive decimals are allowed.
Share links contain item names. Opening them may leave names in history or server logs. Save personal lists as JSON instead of sharing links.
JSON / CSV
JSON restores normalized items and settings, not verified winners or original comments. Without a seed, the next result may differ.
CSV adds a protective character to names that could be read as formulas. Use JSON to keep the original text.

Frequently asked questions
What is a weight in a weighted random picker?
A weight is a probability ratio. If A has weight 2 and B has weight 1, A is twice as likely to be drawn.
Is this the same as a weighted randomizer or raffle picker?
Yes. The tool works as a weighted randomizer for giveaways, raffles, and priority-based draws. Enter one item per line and use larger weights for higher odds.
What happens with weight 0?
Use a period for decimals, for example 1.5. Weight 0 is never selected; positive decimals are allowed.
Can I reproduce the same result?
The same item order, weights, settings and seed reproduce the result. This does not prove that a seed was not chosen for a preferred result.
What if the share URL is too long?
Share links contain item names. Opening them may leave names in history or server logs. Save personal lists as JSON instead of sharing links. JSON restores normalized items and settings, not verified winners or original comments. Without a seed, the next result may differ.
