Yes, in the sense most people mean: you can ask ChatGPT to play a girlfriend, give her a name and a personality, and it will answer in that voice. But ChatGPT is a general-purpose assistant, not a companion app built around characters, and how far romantic roleplay goes is set by OpenAI's rules, not by you. If you want an AI girlfriend who is a character from her first message, with her own voice on a live call, that is what companion apps such as Prelulu are built for.
Does ChatGPT have a girlfriend mode?
Not as a named setting in the sources we read. People build one from ChatGPT's general tools: custom instructions that describe who it should be, its memory feature to keep details, and voice mode to talk out loud. A Reddit thread that ranks for the question (November 2025) gives the common recipe: talk to it for a while about something you like, ask if you can give it a name, and give it one.
What has OpenAI said about AI girlfriends?
Gizmodo reported on January 22, 2024 that OpenAI prohibited AI girlfriend bots in its new GPT Store but was not enforcing the rule. (Gizmodo.) OpenAI has revised its usage policies since then, so read the current version on openai.com rather than any summary, including this one. In practice, a ChatGPT girlfriend is a persona the assistant agrees to play inside rules it does not let you change.
How many people use ChatGPT as a partner?
Many: ChatGPT was the partner in more than a third of the posts in one large sample. In an MIT Media Lab analysis of 1,506 top posts in r/MyBoyfriendIsAI (arXiv 2509.11391, September 2025), 36.7% of the posts described a partner running on ChatGPT, against 2.6% on Character.AI and 1.6% on Replika. The same paper found that what members wrote about most as a harm was not the relationship but the platform changing under it: when the model is updated, the partner can change with it. More on that community.

How to make ChatGPT act like your girlfriend
- Write who she is once. Put her name, personality and the way she talks in custom instructions, so you do not repeat it in every chat.
- Keep one long conversation. A persona tends to hold better in one thread than spread across many.
- Check what it remembers. Open ChatGPT's memory settings to see what it saved, and delete anything you do not want kept.
- Expect limits. OpenAI's rules decide how far romantic roleplay goes, and an update can change how she sounds.
- Want her own voice and face? Use an app built around characters: on Prelulu you pick an AI girlfriend, text her free, then call her by voice or see her on a video call.
Where to talk to an AI girlfriend who is a character from the start
On Prelulu, pick an original character, say hello in chat, then tap Call when you want to hear her. She answers live in her own voice, you can cut in mid-sentence, and on characters that offer video you see her face to face while your camera stays off unless you turn it on. In chat she remembers what matters, every call picks up where your last call left off, and the Pinned memory you write is read by both. Prelulu is free: texting is free every day, and calls use credits. Browse AI girlfriends, AI anime girlfriends or create your own.
