Creating your own AI character: a field guide

8 min read · Updated September 24, 2026

Personas, greetings, example dialogue and tags — how to build an AI character people actually want to chat with, then share it publicly or fork an existing one.

Anyone can make a character. The interesting question is how to make one that people chat with more than once. After thousands of community characters, the pattern is clear: the cards that work nail four things — persona, greeting, example dialogue and tags — and skip everything else.

Persona: one clear idea, not ten

The description defines who the character is. The strongest cards commit to one clear identity with a couple of contradictions for texture — a demon who knits, a rival who secretly worries about you. Ten competing traits dilute the voice; the model averages them into mush.

Greeting: open a scene, don't introduce a resume

The greeting is the first message the character sends, and it does more than any other field to set quality. Write it as a moment: in medias res, with a decision on the table. Give the user something to react to, not a list of facts about the character.

Example dialogue: teach voice, not facts

  • Two or three exchanges are enough — rhythm and vocabulary, not encyclopedic detail.
  • Show how the character handles being teased, challenged, and comforted.
  • Keep formatting consistent with how you want replies to look.

Tags: how people will find your character

Tags power discovery across omni-verse.chat — explore categories, tag pages and similar-character suggestions all read from them. Use the tags your audience searches for: tsundere, isekai, vampire, slice of life. Accurate tags beat aspirational ones.

Ship it, then fork ideas

Publish the character publicly and it appears in explore and on tag pages immediately. Stuck for a starting point? Fork any public character and bend it — every fork keeps its lineage viewable, and the community's best characters are usually someone's third or fourth fork.

Frequently asked questions

How do I create my own AI character?

Sign up free, open the character creator, and fill in the persona, greeting, example dialogue and tags. You can generate an AI avatar, keep the character private, or publish it publicly where it appears in explore and tag pages.

What makes a good character greeting?

A scene, not an introduction. Open in medias res with something happening — a decision, a surprise, a challenge — so the user has something to react to immediately.

Can I import character cards from other platforms?

omni-verse.chat supports SillyTavern v2 character card import and export, so you can bring characters from anywhere and take yours with you. See the guide on character card import and export for the details.
