What generator tools does Texterfly offer?

Texterfly offers 3 free generator tools: a Random Number Generator (custom range, multiple numbers, duplicate control), a Random Name Generator (male, female, or any gender, multiple names), and a Random List Picker (enter any items, pick a random winner, option to remove winners). All are free, browser-based, and require no signup.

Are these generators truly random?

The tools use a pseudo-random number generator (PRNG) based on JavaScript's Math.random(), which is a cryptographically seeded algorithm in modern browsers. For practical purposes — contests, games, creative work, and decisions — PRNG results are considered statistically fair and unbiased. If you need cryptographically secure randomness (e.g. for security tokens), use a dedicated cryptographic library.

What is the difference between pseudo-random and true random numbers?

Pseudo-random numbers are generated by a mathematical algorithm starting from a seed value. They are deterministic but produce sequences that pass statistical randomness tests. True random numbers come from physical sources like atmospheric noise or radioactive decay. For contests, games, and everyday decisions, pseudo-random numbers are perfectly adequate and considered fair.

Can I use the Random List Picker for a giveaway or raffle?

Yes. Enter each participant's name (or any item) on a separate line, click "Pick Winner", and the tool randomly selects one entry. You can optionally remove the winner from the list before picking again for multiple prizes. The selection is statistically fair since each entry has an equal probability of being chosen.

How do I generate a random number between 1 and 100?

Open the Random Number Generator, set the minimum value to 1 and the maximum to 100, and click Generate. You can also set how many numbers to generate at once and whether duplicates are allowed.

Can I generate multiple random numbers at once?

Yes. The Random Number Generator lets you specify how many numbers to generate in one click. You can also choose whether to allow duplicates (the same number appearing more than once in the set). The generation history shows all previous results so you can review past generations.

What types of names does the Random Name Generator produce?

The Random Name Generator produces first and last name combinations drawn from common English-language name databases. You can filter by gender (male, female, or any) and generate multiple names at once. The names are plausible, human-sounding combinations suitable for fiction, game characters, test data, and creative projects.

Can I use generated names for commercial projects?

Yes. The generated names are combinations of common public-domain name components. They are not tied to real individuals and can be used freely in any personal, educational, or commercial project including games, novels, scripts, software test data, and marketing materials.

Are these generator tools free?

Yes. All 3 generator tools are 100% free with no registration, subscription, or payment required.

Is my list data private?

Yes. All operations — number generation, name generation, and list picking — run entirely in your browser using JavaScript. Your list entries, custom ranges, and results are never sent to any server or stored anywhere.

How does the random team generator ensure fairness?

The tool uses the Fisher-Yates shuffle algorithm, which is a well-established method for producing an unbiased random permutation — every possible ordering of names is equally likely. Team sizes are then calculated so the difference between the largest and smallest team is never more than one person (e.g., 10 people into 3 teams becomes 4-3-3, not 4-4-2 or 5-3-2).

Can I keep two people together on the same team?

Yes. Add a "keep together" rule, and the generator will ensure that pair ends up on the same team — useful for pre-formed duos, siblings, or hackathon partners who already know they want to work together.

What happens if the rules conflict or can't all be satisfied?

The tool attempts to satisfy every rule using a bounded number of swap attempts. In rare cases with many conflicting rules and few teams, not every rule can be satisfied simultaneously. If this happens, the tool clearly shows which specific rules could not be met so you can adjust your team count or rules and regenerate.

Should I split by number of teams or people per team?

Use "Number of Teams" when you know exactly how many teams you need (e.g., 4 sports teams). Use "People per Team" when you know the ideal group size but not the total team count (e.g., hackathon teams of 4 people each, however many that produces).

Is this tool free and does it require an account?

Yes, completely free with no account or sign-up. Everything runs in your browser — your list of names is never sent to a server.

Free Random Team Generator — Balanced Groups from Any List

This Random Team Generator uses the Fisher-Yates shuffle — a proven, unbiased algorithm — to split any list of names into fair, balanced teams. Unlike simple "divide the list in order" tools, every possible team arrangement is equally likely, and team sizes are automatically balanced so no group ends up with two fewer people than another.

Add "keep apart" rules to prevent friend groups or coworkers from the same department landing on the same team, or "keep together" rules to preserve pre-formed duos. Need just one random winner instead of teams? Try the Random List Picker. Need placeholder names to test with? Use the Random Name Generator.

Who Uses a Random Team Generator?

🏫

PE Teachers

Quickly split a class into fair teams for sports or activities without playing favorites — students trust a random shuffle more than manual picks.

💻

Hackathon Organizers

Paste your registrant list and split into balanced project teams in seconds. Use keep-apart rules to spread out people from the same company.

🎯

Trivia Night Hosts

Randomly assign teams for pub quiz or trivia night, ensuring groups stay evenly sized as people arrive.

👔

Team Building Events

HR and team leads use random team generators to mix departments for icebreakers and workshops, breaking up existing cliques.

⚽

Sports Coaches

Split a roster into scrimmage teams fairly, or use keep-apart rules to separate players who shouldn't compete against friends.

🎓

Classroom Projects

Assign students to group projects randomly and fairly, with the option to keep certain students apart if needed.

How the Balancing Algorithm Works

The tool first shuffles the full name list using Fisher-Yates — the standard algorithm for producing a truly random, unbiased permutation. It then calculates team sizes using integer division: for N people split into K teams, each team gets ⌊N/K⌋ people, and the remainder is distributed one extra person at a time to the first few teams — so 10 people into 3 teams becomes 4-3-3, never 4-4-2 or 5-3-2.

People	Teams	Result
10	3	4, 3, 3
9	3	3, 3, 3
7	4	2, 2, 2, 1
13	4	4, 3, 3, 3
8	5	2, 2, 2, 1, 1

Frequently Asked Questions

How does the tool ensure teams are actually fair?

It uses the Fisher-Yates shuffle to randomize name order — a mathematically unbiased algorithm where every possible arrangement is equally likely. Team sizes are then balanced so the largest and smallest teams never differ by more than one person.

Can I prevent certain people from being on the same team?

Yes. Add a "keep apart" rule between two names in the Rules panel. The generator will re-shuffle those specific people onto different teams while keeping everything else random.

What if my rules conflict and can't all be satisfied?

The tool attempts up to 200 swap operations per rule. If a rule genuinely can't be satisfied (for example, too many "keep apart" rules with too few teams), it's clearly flagged after generation so you can adjust your settings.

Should I use "Number of Teams" or "People per Team"?

Use Number of Teams when you know exactly how many groups you need. Use People per Team when you have an ideal group size in mind (like hackathon teams of 4) and want the tool to calculate how many teams that produces.

Is this free with no account needed?

Yes, completely free with no sign-up. Everything runs in your browser — your name list is never sent to a server.
