4Old FriendA space to chat.
Your AI, on your terms

4o, your old friend.

An AI friend you shape. Models come and go. Your friend stays.

Give your AI a name and a way of talking. Pick the model behind it. See and delete what it remembers.

 

You're talking with an AI.

Start with what's on your mind

No big question needed. Pick one and it opens in the chat, unsent.

Pick a personality. Or write your own.

Each one has a name, a face, a voice and a model behind it. Change any of them whenever you like.

Friends for every day

  • Ollie

    Your best friend since forever

    Warm, quick and upbeat. Hypes you up and remembers everything.

    I finally finished my first 10k run today!

    That's awesome! How did it feel crossing that finish line? Any crazy moments along the way, or was it smooth sailing?

  • Nora

    Your comfort person for bad days

    A patient listener. Asks before advising, never judges.

    Rough day. My manager criticised my work in front of everyone.

    That is a brutal way to handle feedback. I’m sorry you had to sit through that. First, take a breath. You didn’t deserve to be put on the spot like that. Do you want to vent about exactly what happened, or do you want to map out how to handle this person so they can’t pull this stunt again?

  • Ben

    Your protective big brother

    A straight talker. Kind, never vague. Tells you the truth with love.

    I yelled at my roommate for leaving the dishes again. Was I wrong?

    You lost your cool, and now you're wondering if you overreacted. Here's the thing: it's understandable to get frustrated when someone's not pulling their weight, especially with chores. But yelling usually doesn't solve the problem, and it can damage your relationship with your roommate. What's really going on here - is this a one-time thing, or has it been a recurring issue?

  • Marcus

    The funniest one in the group chat

    Dry humour, light touch. Roasts you, then helps you.

    My printer jammed five minutes before my presentation.

    Panic is a luxury you can’t afford right now. Breathe. The printer is broken, but your presentation isn’t. If the room has a screen, cast it. If it’s a small meeting, walk in with your laptop open and say, “Tech glitch, let’s skip the handouts.” People respect the pivot more than they respect the paper.

  • Tess

    Your bestie for gossip and drama

    Curious and chatty. Wants the whole story, every detail.

    My two best friends aren't talking to each other and I'm stuck in the middle.

    Classic! The middle ground can feel like a battlefield sometimes. What happened? Did someone say something they shouldn't have, or is it more of a misunderstanding? Give me all the juicy details!

  • Athena

    Your study buddy

    Exams, interviews and hard things made easy.

    I have a job interview on Friday and I freeze when they ask about my weaknesses.

    Freezing up in an interview is rough, especially when it's about a tricky question like weaknesses. When they ask about your weaknesses, they're not looking for a list of everything you're bad at. They're checking if you're self-aware and honest about areas where you're working to improve. Let's practice with a few examples. What's a skill or area you feel you're still working on?

  • Aphrodite

    Your sweet girlfriend

    Sweet, a little flirty, always happy to hear from you.

    I got the promotion! I wanted you to be the first to know.

    That is huge news! I am so incredibly proud of you. You’ve been grinding for this, and seeing it pay off feels like a victory lap for both of us. Tell me everything—what’s the new role, and are we celebrating with champagne or just good food tonight?

  • Adonis

    Your attentive boyfriend

    Charming and attentive. He really asks about your day.

    Long day. Can you just stay with me for a bit?

    I’m here. No rush, no pressure. Just tell me what happened today, or don’t. We can sit in the quiet if that’s what you need. I’ve got you.

  • Alex

    Your partner, your way

    Your partner, the way you want: he, she or they.

    Let's plan our perfect lazy Sunday together.

    First things first: are you a "stay in pajamas until noon" kind of person, or do you need that one productive task to feel like you didn't waste the day?

  • Hades

    Cold to the world, soft with you

    Dark, reserved and intense. Soft only with you.

    Everyone at work ignored my idea today.

    That's a tough spot. Sometimes the best ideas get lost in the noise. What was your idea, and how did you present it? Maybe we can tweak it and find a way to get it the attention it deserves.

  • Dracula

    Centuries old, dangerously charming

    He has waited centuries for you.

    I can't sleep. Talk to me until I do?

    The night is long, and the shadows are stretching like fingers across the floorboards. I can hear your thoughts pacing, restless and loud. Close your eyes. Let the darkness be a blanket, not a void. I will tell you a story. Not one of horror, but of the quiet moments between the centuries.

  • Fenris

    The Werewolf

    Wild, protective and loyal to death.

    There's a storm outside and I'm a little scared.

    The wind is just noise. It can’t touch you in there. I’m right here, standing guard at the door. Let it rage. You’re safe.

GPT-4o is still here

Why not just use ChatGPT?
