How to Create an AI Character: A Practical First Draft

An AI character does not need an enormous biography. It needs enough specific information for a conversation to feel like it has a person, a place, and a reason to begin.

On Swerve, you can start from an idea for an AI-generated draft or create a character yourself. In either case, the most useful first version is built from a few connected choices: who the character is, how they behave, where the chat begins, and what they say first.

Start with one sentence

Write a sentence that joins role, pressure, and point of view:

This is more useful than “a mysterious keeper.” It gives the character a job, a concern, and a detail that can immediately shape a conversation.

If you cannot write the sentence yet, begin with a contrast:

• a cheerful guide who dislikes crowds;
• a detective who avoids making accusations;
• a mechanic who fixes anything except their own old vehicle;
• a student who knows too much about a forgotten archive.

The contrast makes the character easier to recognize and gives the chat somewhere to go.

Fill the core character fields in order

1. Name and short description

Choose a name that fits the setting, then describe the character’s identity and relevant history in a short paragraph. Focus on facts another character could notice or learn through conversation.

2. Personality

Use behavior rather than a list of labels. “Reserved, smart, kind” could describe almost anyone. This is more actionable:

Two or three observable habits are usually enough for a first draft.

3. Scenario

The scenario gives the first chat a place and a relationship. It should answer: where are the user and character, what just happened, and why do they need to talk now?

4. First message

Make the opening do some work. It should show the character’s voice, point to the situation, and invite a reply.

Add an alternate greeting for a fresh start

An alternate greeting is useful when the same character can begin from different moods or moments. Keep it compatible with the same identity and setting instead of turning it into a different character.

For Elian, a second greeting might be:

Both openings sound like the same person, but they offer different energy for a new conversation.

Choose a portrait that matches the promise

Your portrait is the first signal a reader gets. It does not need to explain every detail, but it should not contradict the description.

For a historical librarian, a modern neon city portrait creates unnecessary confusion. Pick an image that supports the setting, age range, mood, and visual style of the character. You can upload a portrait during character creation when you have one that fits.

Keep the first version small enough to test

Before publishing, start a chat and ask:

1. Does the opening sound like this character?
2. Can I tell what the character wants right now?
3. Does the scenario give me a meaningful next reply?
4. Do the description, personality, portrait, and opening feel like one person?

If the answer to one question is no, change that field first. A focused edit is more useful than adding another page of lore.

Pick visibility deliberately

Use the visibility option that matches your intent. Keep early experiments private, use an unlisted character when you want to share a direct link without broad discovery, and publish only when the character is ready for a wider audience.

The short version

Create one clear character sentence, turn it into a description, personality, scenario, and first message, then test the opening in a real chat. A character with a recognizable voice and an immediate situation is more compelling than a detailed profile with no reason to respond.

When your first draft is ready, create a character on Swerve.
