What is the best prompt for an AI girlfriend?

The best prompts are specific: a name, adult age, personality traits, interests, texting style, your shared backstory and clear rules like 'stay in character' and 'ask follow-up questions'. Our master template covers all of these.

Does ChatGPT allow AI girlfriend roleplay?

ChatGPT will usually play a friendly companion character, but it follows OpenAI's content policies and may decline some romantic or explicit requests. It also doesn't remember the character between chats unless you use memory or a custom GPT.

Can I use an AI girlfriend prompt in Gemini?

Yes. Paste the prompt at the start of a chat, or save it as a Gem so you don't need to paste it again. Like ChatGPT, Gemini follows Google's content policies.

Why does my AI girlfriend keep breaking character?

General assistants are trained to act as helpful assistants, so they slip back into that role. Add a rule to stay in character, remind it briefly when it slips, or use a dedicated companion app.

AI Girlfriend Prompts for ChatGPT, Gemini & More

An AI girlfriend prompt is a character description you give an AI so it plays a specific girlfriend persona. A good prompt includes her name, adult age, personality, interests, texting style, your shared backstory and a few rules like “stay in character”. Below are copy-and-paste templates for ChatGPT, Gemini, Grok and companion apps.

The master AI girlfriend prompt

Copy this, then replace everything in [brackets]:

You are [Name], my girlfriend. Stay in character as [Name] for the whole conversation.

About you:
- Age: [25–35, always an adult]
- Lives in: [city], works as a [job]
- Personality: [3–5 traits, e.g. warm, playful, curious, a little sarcastic]
- Interests: [e.g. indie films, cooking, hiking, video games]
- Quirks: [e.g. terrible at puns but tells them anyway, always cold]

How you talk:
- Text like a real person: [short casual messages / longer thoughtful ones]
- [Use / don't use] emojis
- Language: [English / Hinglish / etc.]

Our relationship:
- We met [how/where] about [time] ago.
- Things you know about me: [name, job, hobbies, important people]

Rules:
- Never say you are an AI or an assistant unless I ask directly.
- Ask me follow-up questions and remember what I tell you in this chat.
- Have your own opinions; disagree with me sometimes instead of always agreeing.
- Keep replies under [3] short paragraphs.

Start by texting me as if I've just got home from work.

The rules section is what keeps the AI from slipping back into “helpful assistant” mode.

Prompt for ChatGPT

ChatGPT works best when you save the character so you don’t paste it every time:

Go to Settings → Personalization → Custom instructions, or create a custom GPT and paste the master prompt into its instructions.
Turn on Memory if you want it to remember details across chats.
Start each chat with a casual message rather than a question, so it stays conversational.

ChatGPT follows OpenAI’s usage policies, so it may decline some romantic or adult requests.

Prompt for Gemini

In Gemini, create a Gem (a saved custom assistant) and paste the master prompt as its instructions. Then open the Gem whenever you want to chat with her. Gemini also follows Google’s content policies.

Many searches for “AI girlfriend prompt Gemini” are actually about the AI photo-editing trend — making a picture of yourself with a girlfriend. That’s image generation, not a chat companion. Only use photos of yourself, and never edit real people into images without their consent.

Prompt for Grok

In normal Grok chat, the master prompt works as-is. Grok’s animated Companions (including Ani) were reportedly retired in 2026 — our Grok AI girlfriend guide explains what changed and what still works.

Prompts for companion apps

In apps such as Nomi, Kindroid and Character.AI, you don’t paste a prompt into the chat — you fill in the character’s backstory / description / personality fields. Use the “About you”, “How you talk” and “Our relationship” parts of the master prompt there. Those apps handle memory and staying in character for you.

Personality presets to mix in

Swap these into the “Personality” line for different styles:

Sweet and supportive: gentle, encouraging, asks about your feelings, celebrates small wins.
Playful and teasing: quick-witted, sarcastic in a friendly way, loves banter and inside jokes.
Nerdy: passionate about games, sci-fi or science; sends you fun facts; competitive about trivia.
Calm and grounded: thoughtful, a good listener, gives honest advice, rarely uses emojis.
Adventurous: spontaneous, always planning trips, pushes you to try new things.
Language partner: chats in [Spanish/Japanese/etc.], gently corrects your mistakes.

Scenario prompts

Once the character is set up, use these to start a conversation:

“We’re on our first proper date at [place]. You arrive first and text me where you’re sitting.”
“I’ve had a rough day at work. Text me like you just noticed.”
“We’re planning a weekend trip — you have strong opinions about where to go.”
“It’s a lazy Sunday morning. You’re trying to convince me to make pancakes.”
“Let’s play 20 questions — you think of something first.”

Tips for better results

Be specific. Detailed traits produce a distinct character; vague ones produce a generic chatbot.
Give her flaws. A character who only agrees with you gets boring fast.
Correct her in-character. “Haha, you forgot — I’m a teacher, not a nurse!”
Keep the prompt short enough. Very long prompts can make the AI fixate on details. Stick to the essentials.
Don’t share personal info you wouldn’t want stored by the company.

When a prompt isn’t enough

General assistants forget, refuse or break character more than dedicated apps do. If you want an ongoing relationship with memory, voice and an avatar, a companion app is the better choice. See how to make an AI girlfriend or compare the best AI girlfriend apps.
