Name Picker

名前選択

Randomly pick one or more names from a list for giveaways, team selection, random draws, and classroom activities. Enter names, click Pick, and watch the animated selection reveal the winner. Split names into teams, generate tournament brackets, weight entries, and track pick history — all in your browser.

使用方法

Enter names in the text area — one per line, comma-separated, or tab-separated. Set how many names to pick and whether duplicates are allowed. Click the Pick button to randomly select winners with an animated spinning effect. Use the Team Generator to split names into equal groups, or the Tournament Bracket to create single-elimination matchups. Add weights with “Name x3” syntax for weighted entries.

機能

  • Random Name Picking — Pick one or multiple names with cryptographically secure randomness (crypto.getRandomValues). Optional animated spinning effect that cycles through names before revealing the winner.
  • 柔軟な入力 — Enter names one per line, comma-separated, or tab-separated. Quick actions to sort, remove duplicates, shuffle, or clear all names. Live count of entered names.
  • Weighted Entries — Use “Name x3” syntax to give names multiple chances. Perfect for raffle-style draws where some entries have more tickets.
  • ピック履歴 — Running log of all picks in the session with timestamps. Never lose track of previous results. Clear history when starting fresh.
  • Team Generator — Split all names into N equal teams with one click. Re-shuffle to get different team compositions. Great for classroom groups, sports teams, or project assignments.
  • Tournament Bracket — Generate a single-elimination tournament bracket with randomized seeding. Visual bracket display in HTML/CSS.
  • Exclude List — Specify names to exclude from picks without removing them from the main list. Useful for excluding previous winners.
  • Reproducible Results — Optional random seed for reproducible picks. Same seed + same list = same results every time.

ユースケース

Perfect for classroom random calling, giveaway winner selection, raffle draws, team formation for group projects, meeting ice-breakers, Secret Santa assignments, tournament seeding, jury selection simulation, random task assignment, and any situation where you need fair, unbiased random selection from a list of names.

Is the random selection truly random?

Yes — this tool uses crypto.getRandomValues(), the Web Crypto API’s cryptographically secure random number generator. This is the same randomness source used for encryption and security tokens, providing much better randomness than Math.random(). Each name has an equal probability of being selected (unless weights are applied).

Can I use this for giveaways and raffles?

Absolutely. The tool uses cryptographically secure randomness, maintains a timestamped pick history for transparency, and supports weighted entries for raffle-style draws where some participants have more tickets. You can also use the exclude list to prevent previous winners from being picked again in multi-round draws.

How does weighted picking work?

Add a multiplier after any name using ‘x’ followed by a number. For example, ‘Alice x3’ gives Alice three times the chance of being picked compared to a name with no multiplier (which defaults to x1). This is equivalent to entering Alice three times but more convenient. Weights work with all pick modes including team generation.

データがサーバーに送信されていますか?

No — all name picking, team generation, and bracket creation happen entirely in your browser. No names or results are transmitted to any server. Pick history is stored in memory only and disappears when you close or refresh the page.
