Pick a random name from a list with a reproducible seed

This seeded random name picker turns any non-empty list into a reproducible draw order. Supply the same names and seed to receive the same result every time, whether you need one selection or the complete shuffled order. Numbered picks move through that order without repeating an entry until every position has been used. It is useful for games, classroom turns, team activities, giveaways, review assignments, and any fair-looking draw that must be checked or repeated later. All selection logic is deterministic and uses no network service, system clock, or hidden randomness.

Prepare names and choose a meaningful seed

Start with one or more names and a non-empty seed. Each name must be text containing at least one visible character; surrounding spaces are removed before the draw. Spelling and capitalization otherwise remain unchanged.

The seed can describe the event, round, date, or published draw identifier, such as a meeting name combined with a week number. A meaningful seed is easier for participants to record and reuse than an arbitrary value. The exact seed matters: changing one character creates a different deterministic sequence.

Input order also matters because the shuffle begins from the list you submit. For a result that other people can reproduce, share the names in their original order, the exact seed, and the requested mode. Duplicate labels are permitted because two distinct people may share a name, but identical labels cannot be distinguished in the response.

Add a surname initial, team, number, or another qualifier when every entry must be visibly unique. An empty list is always rejected instead of producing a misleading blank selection. The capability also rejects blank names and a blank seed, giving integrations a clear input error to correct before a draw is published.

Pick once or walk through a repeat-free sequence

Use pick mode when you need one name. The default draw number is 1, which selects the first entry in the seeded order. To make another selection without repeating an earlier entry, keep the names and seed unchanged and increment the draw number to 2, then 3, and so forth.

The response reports the selected name, the draw number, how many entries remain, and whether that draw exhausted the list. This makes a stateless integration practical: store only the seed and next draw number rather than storing or mutating a pool of names. A draw number beyond the list length returns an error stating that the list is exhausted.

Use shuffle mode when you want the complete order at once, perhaps to print a speaking schedule or assign every participant a turn. Shuffle mode returns the seed, count, and full ordered list. Both modes use the same permutation, so a pick at draw number 2 always matches the second item returned by shuffle mode for identical input.

Do not change the input order between calls, because even the same membership in a different starting order intentionally defines a different draw.

Reproduce, audit, and integrate the result

Determinism is useful whenever a selection must appear random while remaining explainable. Record the original ordered list, seed, and draw number alongside the result. Anyone can then submit those values again and verify the selection without trusting saved application state.

This is especially helpful for classroom rotations, recurring team duties, tabletop games, community events, and transparent low-stakes giveaways. The algorithm performs a seeded Fisher-Yates shuffle entirely in memory. It never calls a random service, reads the current time, accesses storage, or uses a model, so identical inputs have identical outputs across runs.

Deterministic does not mean cryptographically unpredictable: a participant who knows the list and seed can calculate later positions. Do not use this capability where secrecy, regulated lottery rules, adversarial prize allocation, or cryptographic randomness is required. In an application, validate that the participant roster is final before publishing the seed, retain the next draw number transactionally, and decide explicitly whether a new round resets with a new seed or continues the existing sequence.
