Group Picker – Free Random Group Generator

What Is a Group Picker?

A Group Picker is a random group generator that divides a list of names or items into multiple groups. It randomizes the enabled entries, then distributes them into groups with counts as close as possible.

Use it to organize a discussion, split a workshop into breakout groups, or divide a general list for an activity. It groups the list rather than selecting one result.

How to Use the Group Picker

Prepare the names or items you want to group, choose the grouping method, and press Generate Groups. You can review the groups, copy them or generate another arrangement.

1. Prepare your listAdd one entry or paste one name/item per line.
2. Select a grouping methodChoose Number of groups or Group size, and enter a whole number.
3. Generate GroupsDivide the current enabled list into groups.
4. Review or regenerateCopy Group or Copy All Groups; Regenerate Groups creates another arrangement.

The interface calls entries “participants,” but it accepts arbitrary text labels. You can use item names in the same inputs. No separate item mode or item-classification feature is needed.

Choose the Number of Groups

Number of groups determines how many groups you will receive. Set a whole number from 1 to 500, without exceeding the number of active entries.

For example, choose 3 groups for 12 enabled participants to get sizes of 4 + 4 + 4. A count of 1 is valid and puts the active list into one group. Zero, decimals, values above 500 or more groups than active entries are rejected.

Choose How Many People Are in Each Group

Group size is a maximum target, not an exact size for every group. It accepts a whole number from 1 to 500. The engine rounds the active-entry count divided by the target upward to find the number of groups, then distributes entries evenly.

For 10 people with a target of 4, the output is 3 groups of 4 + 3 + 3, rather than 4 + 4 + 2. The same rule applies to item labels. A target larger than the list puts everyone into one group; a target of 1 gives one group per active entry.

The original Group Picker starts in Group size mode with a target of 3 and ten sample names. Generating from those defaults gives four groups with sizes of 3 + 3 + 2 + 2. Your edited or locally saved list may differ.

What Happens When Names Cannot Be Divided Evenly?

The largest and smallest groups differ by at most one entry. Once the list is shuffled, entries are assigned to groups in turn, and any extra entries go to the earlier groups.

Ten people cannot make three exactly equal groups. The sizes are 4 + 3 + 3, while the shuffled order determines who belongs to each group. This size guarantee does not assess ability or skill.

How Does the Random Group Picker Work?

The Balanced Group Engine shuffles the enabled list first, then distributes entry IDs round robin into the calculated number of groups. Every enabled entry appears exactly once.

The Fisher–Yates shuffle draws random values from the browser’s Web Crypto API. Rejection sampling discards an incomplete modulo bucket so the values map evenly to shuffle positions. Generate Groups and Regenerate Groups start a new shuffle; reopening saved groups does not reshuffle them automatically.

Secure-randomness errors are reported rather than replaced with an insecure random fallback. The implementation is not a certification or a guarantee of fairness.

Are the Groups Random and Evenly Sized?

Yes: the shuffled order randomizes which enabled entry goes into which group, while the distribution keeps group sizes within one entry of each other. Random assignment and even group sizes describe different things.

Exactly equal counts depend on the list length and grouping method. The maximum-size target remains a limit, even when some groups end up smaller.

Can You Generate New Random Groups?

Yes. Press Regenerate Groups to shuffle the current enabled entries again using the current settings. The latest group arrangement is replaced, and there is no result-history ledger.

Another shuffle can produce the same arrangement. Editing the list or changing valid settings clears the old result; press Generate Groups when you are ready to group the updated entries.

Can You Add, Edit or Remove Names?

Yes. Use Add for a single entry or Add pasted participants for a multiline list. Edit a label in place, use Delete to remove it, or uncheck an entry to exclude it without deletion. Clear participants empties the list.

The editor supports up to 500 entries, including disabled entries, and up to 200 characters per label. Empty text is rejected; whitespace is trimmed and normalized. Longer lists use pages of 25 entries with Previous participants and Next participants.

Duplicate labels count as separate entries with distinct IDs. Editing preserves an entry’s ID. For people sharing a name, add a distinguishing initial or other label so the groups are readable. Arbitrary item labels are accepted without checking what they represent.

Reset restores the original ten sample names and settings: Group size mode, target 3, and stored group count 3. It clears generated groups. There is no separate entry-order shuffle control; Regenerate Groups reshuffles the assignments.

Does the Group Picker Save My List and Groups?

Where browser storage is available, localStorage saves the entry list, grouping settings and latest generated groups in the same browser/device/origin. Reloading can restore those groups without a new shuffle; earlier arrangements are not kept as history.

There is no user account, cloud storage, cross-device sync or public sharing. Saved state is not permanent: clearing site data can remove it. If storage is unavailable or blocked, your changes work for the current page session only.

Reset clears this tool’s saved state, restores the sample list and original settings, clears the groups, and saves that reset state where storage works. It does not restore your earlier custom list or reset another tool.

What Can You Use a Random Group Picker For?

Use a random group picker for classroom groups, study groups, workshops, breakout sessions, training activities, project groups, games and event activities. You can also divide general item lists where random grouping fits the task.

Review the output for the practical needs of the activity. The generator does not evaluate experience, compatibility or other participant characteristics.

Group Picker vs Team Picker

Group Picker serves broader random grouping of people or items: classroom discussions, study groups, workshops, breakout sessions and general lists. When your task is specifically team formation, use the Team Picker.

Both use the same Balanced Group Engine, so the distinction is the task, terminology and original configuration—not different randomization technology. Group Picker begins with a size target; Team Picker’s original configuration begins with a team count.

Group Picker vs Random Name Picker

Group Picker divides the enabled list into groups. The Wheel of Names selects one name or result at a time, which suits choosing a speaker or a single participant.

If you searched for a group picker wheel, this page provides random grouping with a list-based generator. The Group Picker does not spin a wheel or use elimination to build groups.
