How likely it is that this went through an AI humanizer
It looks like it came from an AI humanizer.
This text is an AI-generated overview of volleyball that has been passed through a paraphrasing tool to evade detection. It retains the structured layout and balanced coverage of an encyclopedia article while exhibiting stiff phrasing and awkward phrasings.
What Optimal found
- Strong British and American spelling mixed together
The text uses British spelling for some words ("defence", "centre", "colour", "organise") and American spelling for others ("specialized"). People usually stick to one. Grammarly's humanizer often changes only some words to British spelling. This can also happen from autocorrect or copying from different sources.
- Weak "Carry out" used 5 times
Phrases like "carry out attacks" and "blocking is carried out" show up a lot in humanizer output. By itself this does not mean much.
- Medium 3 phrases that AI humanizers often produce
Found: "the fact that", "with the aim of", "a number of". Humanizers such as humanizeai.pro reword a whole AI essay and often leave this kind of formal, slightly unnatural phrasing behind. In testing, plain AI writing and human writing almost never had two or more of these.
- AI review Planted mistake: "the fifth set, which is decider"
An article was dropped before the word decider, creating a non-native slip.
- AI review Odd synonym: "place the ball at the disposal of an attacker"
An unnatural, overly formal phrase is used instead of standard sports terminology.
- AI review AI-style structure: "The various positions have certain responsibilities for the players."
The sentence uses a flat, generic topic structure typical of automated essay generators.
- AI review AI-style structure: "The sport also promotes mental concentration since the players have to react instantly"
The paragraph follows a predictable formula of listing benefits with standard explanatory filler.

Volleyball is a team sport involving coordination, communication, physical ability and the need to make quick decisions; it was invented in 1895 by William G. Morgan, a physical education teacher in Massachusetts who wished to develop a game that was less physically demanding than basketball. At first the sport was known as mintonette, but it later acquired the name volleyball because the players hit the ball over the net. Gradually it spread throughout the world and was included in the Olympic Games in 1964. Nowadays volleyball is played in schools, in recreational leagues, in professional tournaments and on beaches all over the world.
The primary aim in volleyball is to hit the ball over the net and get it down in the opponent's court while at the same time stopping the other side from doing so. In indoor volleyball each side has six players. Generally, teams are permitted three touches when returning the ball, most often involving a pass, a set and an attack. Players are not allowed to catch or hold the ball during regular play. A point is given after each rally no matter which team had served. Matches are usually played as best of five sets, the first four of these sets being played to twenty-five points and the fifth set, which is decider, to fifteen. A team usually has to win a set by two points at least.
Volleyball involves a number of specialized techniques; the serve starts off each rally and may be carried out in a variety of ways such as with an underhand, overhand, float, or jump serve. A powerful serve can exert pressure on the opposing team and lead to possible scores. Passing is also a vital ability since it enables the players to handle the ball as it comes in and then set up an attack. The forearm pass, which is usually known as a bump, is generally used when receiving serves and defensive hits.
The method used to place the ball at the disposal of an attacker is known as setting. Generally, the setter determines the team's attacking strategy by deciding which player should receive the ball. Spiking consists of jumping and hitting the ball with force towards the opposing court. In order for a spike to be successful, it is necessary to have good timing, coordination, and the ability to spot gaps in the defence. Blocking is carried out close to the net with the aim of either stopping or changing the direction of the opponent's attack, while the back-row defenders also employ digging techniques to ensure that strongly driven balls do not hit the floor.
The various positions have certain responsibilities for the players. Setters are in charge of arranging the offensive moves and of distributing the ball. The outside hitters carry out attacks from the left side and often take part in passing and in defensive actions. Opposite hitters usually attack from the right side, whereas middle blockers concentrate on blocking and on carrying out quick attacks close to the centre of the net. Liberos have uniforms that are different in colour and are specialists in receiving and in defensive play; they are subject to limitations regarding their offensive actions and in terms of substitutions when the standard indoor rules apply. All the positions contribute to the team's overall performance.
It is particularly important to communicate since rallies can happen very quickly. Players have to call out the ball, alert their teammates to attacks coming in, and organise their movements. If communication is not clear then two players could end up colliding or the ball might drop between them. The teams also formulate strategies according to their opponents' habits, for example by targeting a weaker passer with serves, changing their blocking positions, or altering the way they attack in order to make the defence less predictable.
Volleyball offers physical advantages by enhancing a person's ability to jump, their coordination, balance, and muscular strength. By carrying out the same movements repeatedly, agility is improved and short periods of intense activity contribute to the development of speed and power. The sport also promotes mental concentration since the players have to react instantly to changes in the direction of the ball. It is also important to learn how to recover from an error. For example, if a player fails to hit the serve or does not defend an attack, he or she must remain involved and be ready for the next rally.
Beach volleyball is a variant of the game, with two players on each side and the match being held on sand. Since there are fewer teammates to cover the court, the players have to take on a greater variety of responsibilities. The fact that the surface is sandy also makes movement more physically demanding and the outdoor conditions such as wind and sunlight add extra difficulties which force the players to adjust their strategies.
To sum up, volleyball is a stimulating sport which involves both individual technique and teamwork, since each successful rally requires the players to work together in receiving, organising and attacking the ball. The sport not only enhances physical fitness but also teaches people to communicate, to be disciplined and to show resilience. Regardless of whether it is played indoors, on the beach or in a school gym, volleyball provides an enjoyable means of competing, forming friendships and acquiring athletic abilities.
Please keep in mind that this is an estimate. Detectors get things wrong, so I would not accuse anyone of cheating based on this alone. Talking to the writer or looking at their earlier drafts is a better next step. Also, generic writing that reads like AI can score high even when a person wrote it, and some humanized text still gets through, especially personal stories (see the Test Results page).
