Create an AI companion who is your kind of company.

Begin with how you want the conversation to feel.

Before choosing a name or a portrait, picture the exchange you would enjoy. Do you want quick banter, unhurried storytelling, or an imaginative adventure? Pick two or three traits that support that mood. Warm and playful creates a different starting point from mysterious and adventurous, even if both characters share the same favorite music.

Try turning an adjective into a small behavior. “Curious” becomes “asks about the story behind an unusual object.” “Witty” becomes “makes gentle jokes without turning every answer into a punchline.” These details help you describe a recognizable voice. They are creative directions, so the actual replies may still vary.

Give them a life beyond the introduction.

A useful backstory supplies conversation openings. You do not need a novel. Choose an interest, an everyday habit, and something the character would like to explore. A fictional illustrator might collect postcards, sketch at a neighborhood café, and dream of designing a tiny seaside bookshop. Each detail gives you a place to take the story.

Keep your character an adult and make the identity your own. Buba is built around fictional characters, so invent a name and background instead of copying a real person. The goal is a character you can describe clearly, with enough open space to surprise you in a story.

• Interest: indie games, astronomy, old films, or imaginary travel.
• Habit: writes in the margins, collects playlists, or always orders tea.
• Story spark: a half-finished comic, a mysterious letter, or a new neighborhood.

Let the look support the story.

Realistic and anime styles offer different ways to picture the same idea. Choose the one that makes your fictional world inviting to you. A warm café portrait might suit quiet conversations; a vivid illustrated character might be the beginning of a city full of impossible adventures. Neither style needs to dictate the personality.

Buba’s character builder brings together an adult character’s name, style, personality, interests, and backstory. You can save a draft on your device or sign in to save it to your account. The image studio is for non-explicit fictional adult portraits and requires a configured provider and account to generate images.

Trade the blank page for one small scene.

A good opening gives both the setting and a choice. Instead of asking the character to carry the entire exchange, place something in motion: the bookshop is closing, the last train has arrived, or two very different songs are competing for a playlist. Then leave a question to answer.

Try: “We are opening a tiny late-night café. You choose the music; I choose the menu. What is our first song?” Or: “Your character found a postcard with no return address. Write the first scene with me.” These prompts work as creative invitations without requiring any real personal details.

Keep the details that make you want another chapter.

After a few exchanges, notice what you enjoyed. Was it the humor, the setting, or the way a simple question became a story? Adjust one detail at a time. If the character feels too intense, ask for a lighter tone. If the scene wanders, restate the setting and your next choice.

You do not need to perfect the profile before having fun. Keep a short character note for yourself if continuity matters; do not rely on the experience to remember every detail. A companion can begin with one clear idea and become a creative project you revisit whenever the mood arrives.
