Random Name Picker

What the random name picker does

Paste a list of names and the picker chooses one — or several — at random. It is built for the situations that come up constantly: who presents first, who answers the question, who wins the prize, who takes the unpopular task. Names appear in large type so the result is readable across a room or a video call.

Every name has exactly the same chance. You can draw several names at once, keep repeats off so nobody is chosen twice in the same draw, remove accidental duplicate entries, and export the result.

How the draw works

Every draw on this page starts with crypto.getRandomValues, the cryptographically strong random source built into your browser. That is a CSPRNG seeded from operating-system entropy: unpredictable in practice, and the right choice when a result decides something that matters. It is deliberately not described as “true randomness”, which would require a physical entropy source such as atmospheric noise or radioactive decay. Tools that claim true randomness from a browser are overstating what the platform provides.

Turning random bytes into a number in your range is where most implementations quietly go wrong. The obvious approach — take a random 32-bit value and apply % range — is biased whenever the range does not divide evenly into 2³². Some outcomes get one extra chance out of every four billion draws, which sounds negligible but is a genuine, measurable defect. This tool uses rejection sampling instead: draws landing in the incomplete final block are discarded and redrawn, so every value is exactly equally likely.

Drawing more than one name

Raise the count and the tool samples without replacement using a partial Fisher–Yates shuffle, so each name can appear at most once. Ask for more names than the list contains and it explains the problem rather than looping or silently repeating someone. If you genuinely want repeats — drawing with replacement, as when the same person may be selected again — untick “no repeats”.

Worked example: choosing three presenters from a class of six

Six names, three picks, no repeats. Each student has a 50% chance of being in the selection:

Names     Alice, Ben, Chloe, Daniel, Emma, Finn
Picks     3, no repeats
Selected  Emma, Ben, Finn
Remaining Alice, Chloe, Daniel

The remaining names are shown deliberately. In a classroom the students not chosen care as much as the ones who were, and displaying both makes the draw visibly complete rather than selective.

Using it in a classroom

Cold-calling by memory is not neutral. Teachers reliably call on the same students more often without intending to — those who sit centrally, those who answer readily, those whose names come to mind. A visible random draw removes that pattern and, just as importantly, is seen to remove it, which changes how students respond to being picked.

The practical caveat is that pure randomness has no memory: the same student can be drawn twice in a row across separate draws, which feels unfair even though it is not. For a single lesson, draw several names at once with no repeats rather than drawing one at a time.

Using it for prize draws

For an informal giveaway this is appropriate: the draw is uniform, uses secure randomness, and shows the full entry count alongside the winner. For anything where the result might be challenged, switch to seeded mode, publish the seed and the entry list beforehand, and run the draw afterwards — then anyone can reproduce your exact result and confirm it.

What no tool can do is certify that your entry list was complete or that the draw was run only once. Those are procedural questions. Publishing a seed is the practical way to answer the second one.

Weighting, and why to be careful with it

Weights are supported — write Name | 3 and enable them — but they should be used sparingly with people. A weighted classroom draw is not a fair draw, and a weighted prize draw needs disclosing to entrants. The tool displays a warning whenever weighting is active precisely because a weighted result looks identical to a fair one once the settings are out of view.

Privacy — and why it matters here specifically

Names are personal data. This tool processes them entirely in your browser: they are never uploaded, never stored on a server, and deliberately excluded from shareable links, so a URL you paste into a staff chat cannot carry your class list with it. If you need to keep a record, export it yourself rather than relying on the page to remember.
