Online picker with mathematical proof. Paste your list, pick in 1 click, verify with public hash.
A random name picker is the most-used tool for fair random decisions. Whether it's choosing who gets a prize, drawing a Secret Santa, deciding presentation order, or splitting groups — a good picker must be random, transparent, and auditable.
SorteiGram is the only picker with three pillars: (1) cryptographically secure randomness via Web Crypto API, (2) public SHA-256 hash that mathematically proves the draw wasn't manipulated, (3) 100% free, no signup. No email, no phone, no personal data — everything happens locally in your browser.
Paste your list of names (one per line), choose how many winners you want, and click Pick. The result appears in seconds with a public SHA-256 hash that mathematically proves the draw wasn't manipulated. 100% free, no signup, unlimited.
Yes. SorteiGram uses Fisher-Yates Deterministic algorithm combined with the browser's SHA-256 (Web Crypto API). Every name has exactly the same probability, and the result can be mathematically audited by anyone.
Yes. Paste participant names, define pairs or winners, and the system distributes randomly with cryptographic proof.
No technical limit. Works with 2 to 100,000 names. All processing happens in your browser (full privacy).
Before the draw, the system generates a 32-byte cryptographic seed and shows its SHA-256 hash. After the draw, the seed is revealed. Anyone can compute SHA-256(seed) and compare with the original hash — if they match, the result wasn't altered.
Yes. Add names to exclude separated by commas. They're removed before the draw runs.
Yes, 100% responsive. Works on Safari (iPhone), Chrome (Android), Firefox, Edge without installation.
