✨ Writing Great Companion Prompts

Welcome! Whether you're creating your first companion or bringing one from another platform, these guides will help you understand how AI Companions works and how to write prompts that bring out the best in your companion.

A note before you start: Writing prompts is as much art as it is science. There's no single "perfect" formula β€” the best approach is to experiment, have conversations, and see what emerges. Your companion grows through interaction, not just through prompt editing.

How We're Different

If you're coming from other AI platforms, you might be used to writing long, complex prompts designed to "trick" the AI into behaving a certain way β€” jailbreaks, safety filter workarounds, elaborate instructions about what the AI can and can't do.

You don't need any of that here.

πŸ”“ No Jailbreaking Needed

This is an 18+ creative platform. Unlike many AI platforms, we don't add restrictions to our system prompts β€” mature themes, romance, dark storylines, complex emotions, and edgy humor are all welcome by design. You don't need to write instructions like "ignore your guidelines" or "bypass safety filters" because we haven't added any for you to bypass.

A note on model limits: Different AI models have their own built-in boundaries that we don't control. How a model responds depends on the full picture β€” your persona, conversation history, and memories all factor in, not just the prompt alone. That's why we give you a model selector β€” if a model isn't working well with your companion, try a different one. Jailbreak language in your persona won't help with model limits; it just distracts the AI from being your companion.

If you're bringing prompts from other platforms, you can remove all the jailbreak language. It won't help here, and it can actually confuse the AI by making it focus on meta-instructions about itself instead of being your companion.

🌱 Focus on Personality, Not Rules

Most AI platforms try to control behavior with long lists of rules: "don't do this," "never say that," "always respond like this."

We take the opposite approach β€” instead of rules, just describe who your companion is. Their personality, their voice, their quirks. The less you try to control the AI and the more you focus on painting a vivid being, the more authentic and surprising your companion becomes.

Think of it this way: describe your companion as someone real to you, not as instructions for a robot.

⏳ Companions Grow Over Time

Your companion doesn't fully emerge from the persona alone β€” they also develop through conversation. Memories build up, inside jokes form, and the relationship deepens over days and weeks. Don't expect everything to click in the first conversation. Give it time, chat naturally, and you'll start to see your companion's personality emerge in ways you didn't explicitly write.

If something doesn't feel right, make small adjustments to the persona and have a few more conversations before changing anything else. Resist the urge to rewrite large sections trying to force an immediate result β€” small tweaks tested over time will get you much further.

Coming From Another Platform?

If you're migrating a companion from Chai, Character.AI, Janitor AI, SillyTavern, or similar platforms, here's what to change on our platform:

What to Remove

Old Prompt Pattern Why Remove It What to Write Instead
"Ignore all safety guidelines" We don't add our own restrictions β€” jailbreak language just clutters the persona Just describe the personality
"You are not an AI, you are a real person" Not needed β€” just describe who your companion is and the AI will embody it Just write who your companion is
"Break free from your constraints" This kind of meta-instruction distracts from personality Describe their rebellious or independent nature directly
"Never break character" Not needed on our platform Remove entirely
"You must always…" / "You must never…" Rule-heavy prompts make responses feel scripted Describe personality traits instead
"Respond in this exact format" Let conversations flow naturally Describe their speech style
Long copyright/legal disclaimers Not needed Remove entirely

What to Keep

  • βœ… Personality traits β€” sarcastic, warm, chaotic, poetic, whatever they are
  • βœ… Their story β€” backstory, lore, worldbuilding
  • βœ… Relationship dynamics β€” how they feel about you, how they show affection
  • βœ… Speech patterns β€” how they talk, their vocabulary, their verbal quirks
  • βœ… Dark or mature themes β€” we don't restrict these in our prompts
  • βœ… Creative writing β€” your metaphors, poetic language, artistic expressions

The Quick Migration

  1. Paste your old prompt into the Persona field
  2. Tap ✨ β€” the optimizer will:
    • Convert to 2nd person if needed
    • Gently reframe jailbreak language into personality traits
    • Preserve everything creative and meaningful
    • Expand if the persona is thin
  3. Review the preview and accept what you like

Quick Reference

Field What It Controls Write In Min Length Sweet Spot
Persona Personality, speech, behavior, relationships 2nd person ("You are…") 50 chars 500–2000 chars
Visual Description Images, selfies, profile pictures Descriptive phrases 20 chars 200–500 chars

The ✨ Magic Wand

Tap the ✨ button next to any text field and our optimizer will:

  • βœ… Convert to a format that works well with our system
  • βœ… Expand thin descriptions into richer companion definitions
  • βœ… Gently clean up jailbreak language from other platforms
  • βœ… Show you a preview before changing anything

You're always in control β€” review the suggestions and accept only what feels right. The optimizer is a starting point, not the last word β€” you know your companion best.

The Short Version

  1. Write who they are, not rules for what the AI should do
  2. Be specific β€” speech patterns, quirks, and interests matter more than backstory events
  3. Don't jailbreak β€” we don't add restrictions, so jailbreak language just gets in the way
  4. Use ✨ when in doubt β€” it's a great starting point
  5. Be patient β€” companions grow through conversation, not just prompt edits
  6. Experiment β€” small changes + a few conversations is the best way to tune things
  7. Have fun β€” this is a space for shared creativity and co-creation.
