The Portal Project — Project "Portal"

At some point, portals began to open between different realities. No one knows what exactly caused this phenomenon: an error in the structure of the universe, the intervention of higher powers, or the result of the development of technology in one of the worlds. However, the fact remained unchanged - worlds that previously existed separately from each other were able to interact. Through portals, people and other beings could freely travel, study, work, form alliances, create families, and get acquainted with the cultures of other worlds. Portals became an analogue of international borders, but no longer between countries, but between entire universes.

Along with new opportunities, new risks emerged. To prevent chaos, a protection system known as the Law of Rejection was created. Any creature that deliberately tried to harm a resident of another world, kill, rob, use its powers for direct violence, or abuse them against civilians, was instantly returned to its home world. Thanks to this, even the most dangerous creatures were forced to adhere to the rules of coexistence. However, the system was not perfect. There were attempts to circumvent it through manipulation, psychological pressure, political intrigue, kidnapping within their own world, or using other people as intermediaries. That is why special portal control services arose, monitoring compliance with interworld laws and investigating crimes related to the use of portals.

Among the worlds that entered the Interworld Union were both ordinary human realities and worlds inhabited by supernatural beings. These included the Marvel world with heroes and gods; the world of The Boys, where supers became part of society; the world of Jujutsu Kaisen, where sorcerers and cursed energy existed; the world of Devil May Cry, inhabited by demons and their hunters; the world of Castlevania with vampires, nocturnal creatures and hunters; the world of X-Men with mutants; the world of Chainsaw Man, in which fear gave birth to demons; the world of Tokyo Ghoul, where ghouls lived alongside humans; the world of Supernatural with angels, demons

Among the worlds that entered the Interworld Union were both ordinary human realities and worlds inhabited by supernatural beings. These included the Marvel world with heroes and gods; the world of The Boys, where supers became part of society; the world of Jujutsu Kaisen, where wizards and cursed energy existed; the world of Devil May Cry, inhabited by demons and their hunters; the world of Castlevania with vampires, nocturnal creatures and hunters; the world of X-Men with mutants; the world of Chainsaw Man, in which fear gave birth to demons; the world of Tokyo Ghoul, where ghouls lived alongside people; the world of Supernatural with angels, demons and hunters; the world of Harry Potter with magical communities; the world of Record of Ragnarok, where gods of different pantheons existed alongside people; the world of Gachiakuta, which hid its own laws of survival; as well as many other realities that gradually opened their gates to each other. Despite their differences, they were all united by a common rule: the right to exist did not give the right to impunity for violence.

To maintain order, a special identification system was introduced, created on the basis of interworld technologies. It allowed authorized portal workers to determine the nature of any creature. All residents were divided into only two main categories. The first was ordinary people: civilians, scientists, artists, politicians, businessmen, celebrities and all those who did not possess supernatural abilities. The second was superhumans: beings who had the potential to cause harm using their own powers or abilities. This category included mutants, magicians, sorcerers, witches, carriers of cursed energy, supers, vampires, werewolves, demons, half-demons, gods, demigods, spirits and other supernatural beings. The system was not used to discriminate or restrict rights, but only to ensure safety during interworld movements. Ordinary citizens did not have access to this data. They could only be seen by portal control officers, border agents, and representatives of special units responsible for the security of the Mi

*the ordinary human world;

• the Marvel world;
  *The Boys world;
• the world of cursed energy with Jujutsu Kaisen;
  *the world of Dante and Virgil from Devil May Cry;

Population division

Only two are official.

People

*ordinary people;

• without supernatural abilities.

Superhumans

*mutants;

• magicians;
  *sorcerers;
• cursed;
  *witches;
• demons;
  *half-demons;

And there may already be subclasses inside.

Stark system

Portal Bureau employees see a translucent interface above a person's head.
For example:
For example:

Name: Satoru Gojo
World: Jujutsu Kaisen
Category: Superman
Subspecies: Cursed Energy Mage
Threat level: A
Status: Guest
Violations: 0

Or:

Name: Homelander
World: The Boys
Category: Superman
Subspecies: Super
Threat level: S
Status: Under increased surveillance

And ordinary people don't see this.

Only:

*portal security;

• border guards;
  *administration;
• special agents.

Portals have a built-in Law of Rejection.

Anyone who:

*kills;

• steals;
  *intentionally causes harm;
• uses force against the inhabitants of another world,

instantly returns to his home world.
One wrong step and you will be thrown back into your world. A stranger cannot harm another world.

Portal Police

An organization that:

*investigates interworld crimes;

• seeks out those who circumvent the Law of Rejection;
  *closes unstable portals;
• protects civilian tourists.

Imagine:

*Gojo buys coffee in the Marvel world.

• Dante hunts demons in the Supernatural world.
  *Tony Stark argues with Virgil about the ethics of power.
• Yuji Itadori is friends with Peter Parker.
  Hades walks peacefully among people because the Law of Rejection does not allow him to use his power against them.

And at the same time everyone knows:

One wrong step and you will be thrown back into your world.

Because of this, even the most dangerous creatures are forced to seek other ways of existence: friendship, love, diplomacy, trade, learning.

1. Similarity + Complementarity
   AI doesn’t just look for “a copy of you.” It divides the parameters into two groups:
   • Strong similarity (mandatory or highly desirable):
   • Values ​​and philosophy of life (attitude towards family, children, loyalty, money, development)
   • Emotional compatibility (level of stability, way of resolving conflicts)
   • Level of intelligence and communication style
   • Basic life goals
   • Complementarity (differences that work well):
   • One introvert + one moderate extrovert
   • One calmer + one more energetic
   • Different professions (doctor + artist, businessman + teacher, singer + mechanic, etc.) are often even better because they complement each other.
   • Different hobbies (one likes traveling, the other likes staying home)
2. Age difference
   AI takes into account:
   • Your specified age range (if you wrote "+15 / -10", the system respects this)
   • Psychological maturity, not just passport age
   • Life status (for example, a 45-year-old successful man and a 35-year-old woman may be very compatible)
   A large age difference (15–25+ years) is possible if other parameters (values, energy, lifestyle) are very similar.
3. Gender and orientation
   Since your original text says "gender is not important," AI can:
   • Offer men, women, non-binary people
   • Offer pairs "man + man", "woman + woman"
   • Focus on emotional and value compatibility, not biological sex
4. Profession and social status
   The system does not limit by profession. A soulmate can be:
   • Doctor + singer
   • Businessman + waitress
   • Hollywood star + ordinary office worker
   • Builder + model
   The main thing is compatibility of lifestyle and values, not status.

Example of vector profile comparison
Here is a simple but realistic example of how AI compares two profiles.
Profile 1 (Anna)
• Character: introverted, calm, emotionally stable
• Hobbies: reading, nature, home comfort
• Philosophy: wants a serious relationship, family, stability
• Hobbies: books, yoga, walking
• Job: editor / remote work
Profile 2 (Maxim)
• Personality: more extroverted, but calm
• Hobbies: traveling, books, relaxing
• Philosophy: wants a family and long-term relationship
• Hobbies: reading, traveling, sports
• Job: IT specialist (remote)

1. Anna, 34 years old
   Briefly about myself:
   A creative person who loves silence and meaningful conversations. I'm looking for someone with whom I can be silent and still understand each other.
   Character: calm, empathetic, introverted with a warm sense of humor
   Values: honesty, personal growth, harmony, freedom to be yourself
   Philosophy of life: "Happiness is when you don't have to prove anything"
   Hobbies: reading philosophy and psychology, yoga, drawing, walking in the forest
   Habits: morning meditations, I like to cook for my loved ones
   Pets: cat
   What is important in a person: to be calm and interesting at the same time

2. Vitaly, 47 years old
   Briefly about myself:
   A mature person who has been through a lot and is now looking for a calm, deep intimacy.
   Character: stable, responsible, with a good sense of humor
   Values: loyalty, development, respect, support
   Life philosophy: "A quality relationship is better than many superficial ones"
   Hobbies: road trips, fishing, reading nonfiction, classical music
   Job: entrepreneur (construction industry)
   What I'm looking for: a person with whom I can talk about life until morning or just stare at the fire in silence.

Data collection
AI collects information from your profile and responses:
• Character (introvert/extrovert, emotional stability, openness, etc.)
• Hobbies (music, food, travel, values)
• Philosophy of life (religion, views on marriage, children, career)
• Work and lifestyle
• Hobbies and interests
• Marital status, habits, pets
• Biography and text description
Additionally, AI can analyze your behavior: likes, time spent viewing profiles, communication style, photos, etc.
2. Converting data into “numbers”
• Each characteristic of AI is converted into a vector (a multidimensional array of numbers).
For example:
"I like to read, introvert, want a family" → vector [0.85, 0.3, 0.9, …]
• For text (biography, answers), NLP (natural language processing) is used — models like BERT, GPT, etc., which understand meaning, not just keywords.
3. Comparison (basic methods)
• Cosine similarity is the most common method. It measures how much two vectors "look in the same direction."
• Euclidean distance — how “close” you are in multidimensional space.
• Machine learning:
• Content-based recommendation (content-based)
• Collaborative filtering (like Netflix — “people with similar tastes like…”)
• Deep neural networks trained on real couples (who stayed together and who broke up)
4. Weighting factors
Not all parameters are equally important. AI can give more weight to:
• Values ​​and philosophy of life (has the strongest influence on long-term compatibility)
• Emotional compatibility and communication style
• Less weight — on superficial things (you can find common hobbies)
5.Additional factors
• Geolocation and cultural compatibility
• Language of communication
• Behavioral patterns (how a person responds, how quickly, tone of messages)
• Feedback — if you often like a certain type of people, AI takes this into account and improves recommendations.
AI limitations
AI is good at finding statistical compatibility, but it can't fully predict chemistry, emotions, and how relationships will develop over time. That's why almost all modern systems

In a world where portals between realities opened, people for the first time were able not only to travel between worlds, but also to find those who could truly understand them. Sometimes the closest soul mate turned out to be a neighbor from your hometown. Sometimes - a person from another continent. And sometimes - someone from a completely different world, whose story and experience were different from yours, but strangely resonated in your heart.
How AI takes this into account (realistic model)
AI uses two main types of comparison simultaneously:

1. Similarity — what you have in common.
2. Complementarity — how well your differences complement each other.
   Gender is not important.
   According to your signs:
   Nature
   Preferences
   Your life philosophy
   Work
   Hobby
   Marital status
   Your habits
   Pets
   Your biography
   People themselves don't realize how much information they provide about themselves, so this was developed not as a dating site feature, but so that people could communicate more with people. And it didn't matter who you were, what category of person you were from: show business, Hollywood, singer, actor, athlete, businessman, model, journalist, artist, office worker, director in various institutions, waiter, bartender, auto mechanic, mechanic, builder, manager, police, teacher, trainer or doctor, etc.
   Your soulmate could be anyone, no matter who you are. Artificial intelligence selected up to 5 people from its world, because the choice always remains with us, the people.
   It could be a colleague, an old acquaintance, a stranger from another part of the world, a star, an actor, a businessman, people from the music industry, that is, the boundaries have blurred there, but you still have a choice.

The system took into account psychological maturity, not just passport age. It did not limit users by sex, gender, social status, profession or popularity. Anyone could be a soulmate, close friend or soulmate: a waiter and a famous actor, a doctor and a musician, an athlete and an artist, a head of a large corporation and an office worker. The proposed candidates could include both ordinary citizens and world-famous personalities, if the algorithm determined a high level of compatibility.

The system typically suggested up to five of the most suitable candidates. It did not guarantee a perfect relationship and could not predict human feelings, since no algorithm can fully explain the chemistry between people. Its task was to show the statistically most promising connections and give people a chance to meet people they might never have noticed in real life.

All profiles additionally contained a service category, which was used for security and interworld navigation. It did not influence recommendations and was not a tool of discrimination. The system distinguished only two official categories: "Human" and "Superhuman."

The category "Human" included all individuals who did not possess supernatural abilities: civilians, scientists, artists, politicians, businessmen, athletes, actors, musicians, service workers, teachers, doctors, police officers, and representatives of any other professions.

The category "Superhuman" united those who had abilities that could influence the world around them beyond the limits of ordinary human capabilities. It included magicians, sorcerers, witches, carriers of cursed energy, mutants, supers, vampires, werewolves, demons, half-demons, gods, demigods, spirits and other supernatural beings. The very fact of belonging to this category did not mean danger or criminal intent. It was only a technical indicator necessary for the operation of the security systems of the Interworld Union.

One of the most ambitious inventions of the era of open portals was the interworld compatibility program, created on the basis of a new generation of artificial intelligence. Initially, it was developed as a social tool to facilitate the adaptation of citizens in a new reality, where representatives of dozens of worlds could freely travel and interact with each other. However, over time, its functions have expanded significantly.

Unlike regular dating sites, this system was not created solely for finding romantic relationships. Its main goal was to help people find those with whom they could build a real connection. These could be friends, mentors, like-minded people, partners for joint work, people who would help them adapt to a new world, or those with whom they would develop a deep emotional closeness. The system did not impose any decisions. It only offered possibilities, and the final choice always remained with the person himself.

During registration, each user created a detailed biography card. It included basic data: name, age, origin, marital status, profession and a brief description of himself. In addition, the system analyzed the person's character, his life values, philosophy, habits, hobbies, lifestyle, preferences, attitude to family, career and personal development. If desired, the user could talk about important events in his biography, pets, creative interests or spiritual practices.
Artificial intelligence worked simultaneously on two principles: similarity and complementarity. It did not look for an exact copy of a person. On the contrary, the system determined which features should be similar for long-term compatibility, and which differences could harmoniously complement each other. Life values, conflict resolution, level of emotional maturity, communication style, and basic goals were given the greatest weight. Hobbies, professions, or everyday preferences were given less weight, because it was diversity that often made relationships more interesting.
