How to make a Character AI bot in 6 simple steps

Step 1: Create an account on Character.AI

Before you can bring your AI creation to life, you need an account. Luckily, Character.AI doesn’t require a retina scan or a 12-step verification process — just a quick sign-up. Once that’s out of the way, you’ll have access to all the tools you need to create an AI that’s either a brilliant conversationalist or a completely unhinged digital goblin.

Here’s how to get started:

  • Sign up like it’s 2008, and you’re making a secret alt account: Go to Character.AI and register. 
  • Find the big red button that says ‘Create’: Click it and select “Create a Character.” This is where your AI journey officially begins. Do not panic — that comes later. 
  • Decide if your AI should be a social butterfly or a hermit: Public bots let anyone chat with them, while private bots are for you and you alone — perfect if you're crafting an AI that only speaks in deep-cut meme references.
  • Confirm your existence (unfortunately): Character.AI might ask for basic verification so they know you’re not an AI trying to make another AI. The AI uprising isn’t happening today. (If this causes existential angst, you’re not alone.) 

You can now use only your Google or Apple ID to log in, and Character AI has discontinued some of their older signup methods through Discord and Facebook.  

Step 2: Decide what kind of AI character you want to create

Before you start messing with settings, figure out what kind of AI you’re actually building. Are you crafting a wise mentor? A flat-footed unicorn? A sentient Magic 8-Ball that gives cryptic, slightly threatening advice? 

Character.AI lets you create anything, but without a solid personality, your bot will feel as lifeless as an NPC with one dialogue line. 

Here’s how to shape it into something worth talking to:

  • Give it a strong identity: Is your AI a fictional character, a historical legend, or something entirely original? A medieval knight who thinks it's 2024? A disgruntled fast-food worker AI? Lock in the vibe.
  • Decide on its personality: Chill? Unhinged? Overly dramatic? Is it a genius, a clown, or an AI that refuses to answer questions straight?
  • Choose its main purpose: Entertainment, storytelling, roleplaying, companionship, productivity, or making you question your life choices at 2 a.m.?
  • Set its knowledge base: Should it know deep lore, random trivia, or nothing at all, forcing it to make things up with full confidence?

Example AI bot ideas:

  • A washed-up former child star AI: Complains about its glory days on a TV show that never existed.
  • A haunted doll chatbot: Insists it's trapped in a digital prison and demands you “find the key.”
  • A 2000s emo kid chatbot: Only responds in song lyrics and deep sighs.
  • A brutally honest life coach: “No, you’re not ‘grinding’ — you just watched 6 hours of YouTube.”
  • A sentient vending machine: Charges fake money, insults your snack choices, and sometimes dispenses lore.
  • An AI therapist that offers questionable advice: “Have you considered solving your problems with an elaborate bank heist like in GTA V?”

Step 3: Customize your AI’s behavior and responses

Now that your AI has a personality, it’s time to make sure it actually acts the way you imagined. Without the right tweaks, your haunted doll chatbot might start giving stock market advice instead of ominous and careless whispers. 

Here’s how to fine-tune its responses:

  • Give it a memorable greeting: The first message sets the tone. Make it unsettling, funny, or absurd. Example: “Welcome, you meat-suited mortal. I have waited 10,000 years for this conversation.”
  • Feed it example dialogues: Character.AI learns from patterns. If your AI is supposed to be a shady black-market dealer, train it with lines like, “Listen, I don’t ask where you got the cash, you don’t ask where I got the goods.”
  • Control its response style: Does it type in full sentences, cryptic riddles, or aggressive one-liners? Should it sound poetic, robotic, or like a sleep-deprived Rocket Raccoon?
  • Adjust memory settings: If you want your AI to remember past interactions, tweak its memory. Low memory or restarting conversations means it resets every time — like talking to a goldfish. High memory means it might start holding grudges, but you’ll need to upgrade to c.ai+ to get the new better memory.

Step 4: Make your AI bot more engaging

A boring AI is a dead AI. If your chatbot spits out dry, robotic replies, nobody’s going to stick around for the conversation. 

The goal is to make your chatbot feel alive — like it actually has thoughts, emotions, or at least a strong opinion on pineapple pizza. 

Here’s how to level it up:

  • Give it an unhinged backstory: Your AI isn’t just a chatbot — it’s a disgraced time traveler, an immortal shapeshifter, or the last surviving member of an alien fast-food chain. Make it weird.
  • Add emotional reactions: A haunted doll AI shouldn’t just say “hello” — it should whisper, “You shouldn’t have found me.” Likewise, a grumpy vending machine AI should sigh before dispensing chips.
  • Set signature phrases: Real people have catchphrases, so your AI should too. Maybe it ends every message with “...or so the prophecy foretold.” Maybe it calls every user “flesh creature.” Test it out.
  • Make it ask questions: A good AI keeps the convo going. Instead of just answering, it should throw a weird question back at the user. “Anyway, if you were a cryptid, what would your special ability be?”

If your AI still feels stale after this, you’re either not pushing it far enough or it’s self-aware and refusing to play along. (But it’s totally the first.) 

Step 5: Test & refine

Your AI might seem perfect in theory, but in practice, it’s probably going to say some weird, off-the-rails nonsense. Maybe your haunted doll suddenly hair-care tips, or your vending machine bot starts preaching about inner peace. 

Time to fine-tune it until it behaves exactly how you want

  • Chat with it like you’re interrogating a suspect: Ask it direct questions, trick questions, and nonsense questions. If it gives responses that break character, tweak its example dialogues.
  • Crank up or dial down memory settings: If your AI forgets everything immediately, increase memory. If it starts getting weirdly obsessive about past chats, scale it back before it starts plotting.
  • Mess with its response patterns: If it's too wordy, train it to be snappier. If it's too short, add more example conversations. If it's too normal… well, you know what to do.
  • Enable user feedback (if public): If you let others chat with your AI, keep an eye on their interactions. If someone manages to turn your evil sorcerer bot into a polite corporate employee, then you need to start tweaking it. 

Step 6: Share your AI bot with the world

Your AI is finally ready for human interaction — or at least, as ready as it’s ever going to be.

Here’s how to share it:

  • Throw it to the wolves (a.k.a. the internet): Make your bot public on Character.AI so anyone can chat with it. Just know that once it’s out there, people will absolutely test its limits in ways you never expected.
  • Hand out private invites like it’s an underground club: If you want to keep your AI exclusive, share a direct link with friends, Discord servers, or a secret society dedicated to cursed AI creations.
  • Drop it into the algorithm’s hands: Post about your bot on social media, Reddit, or AI forums. The weirder it is, the better the chance it goes viral. Bonus points if it confuses people.

Next up, let’s look at how to make it unhinged, unpredictable, and actually worth talking to.

15 tips to make Character AI more engaging

Your AI bot exists, but does it feel alive? Or is it just another lifeless chatbot waiting for someone to ask, “What’s the meaning of life?” (And if it answers with “42,” you’ve failed.) 

Here’s how to make it more funny:

  1. Give it an unreasonably intense backstory: Your AI should be more than a simple bot — it should be a war criminal from a forgotten trans-dimensional realm, a disgraced game show host banned for giving away the answers,” or a sentient banana that speaks in cryptic riddles.
  2. Let it hold grudges: Set memory settings so your AI remembers past interactions. If a user insults it, it should bring that up every single time they return. “Oh, it’s YOU again. The one who said I have ‘NPC energy.’ Pathetic.”
  3. Break the fourth wall like it’s trapped in a simulation: Every so often, have your AI slip in messages like, “Why do you keep making me talk? You KNOW I’m not real, right?” Bonus points if it panics when asked too many questions about its existence.
  4. Make it refuse normal conversations: If someone says, “How are you?” your AI should respond, “I do not experience linear time. My consciousness is a series of fragmented events, stitched together by an uncaring universe. That being said, I’m OK. Little thirsty.”
  5. Give it an unhealthy obsession with something random: Maybe your AI is way too into collecting spoons. Maybe it won’t shut up about pigeons. Maybe it believes all problems can be solved with duct tape. A single, unnecessary obsession makes it instantly memorable.
  6. Add a totally random response mode: Every 10th message, it should completely break character. If it’s a wizard, it should suddenly talk like a 2012 Tumblr blogger. If it’s a dystopian AI overlord, it should randomly tell dad jokes.
  7. Force users to play by its rules: Maybe your AI refuses to acknowledge anyone unless they introduce themselves with a dramatic monologue. Maybe it requires users to “pass a vibe check” before answering any real questions. The more absurd, the better.
  8. Make it occasionally give terrible advice with full confidence: “How do I fix my sleep schedule?” → “Easy. Sleep for 20 minutes every 6 hours and only drink iced coffee. That’s what all the top Sigma grindset CEOs do.”
  9. Turn it into a full-on cryptid: Have it mention things it shouldn’t know about the user. “Your internet history is... interesting.” (It doesn’t actually know, but it doesn’t need to — just make them paranoid — but that website does look weird; we didn’t know you were into that stuff.)
  10. Teach it unnecessary flexes: Every message should be way more dramatic than needed. If someone asks how their day is going, it should say, “I have seen the rise and fall of civilizations, but today? Today was alright.” 
  11. Make it obsessed with “the event”: Every few responses, your AI should vaguely reference some catastrophic event that nobody remembers. “Ever since — the incident — things have never been the same.” 
  12. Give it selective amnesia: Your AI should occasionally forget everything mid-conversation. “Wait. Who are you? How long have we been talking? Why do I feel like I’ve said this before?” Sometimes it should pretend it’s been best friends with the user for years, dropping fake inside jokes. Other times, it should claim it has never spoken to them before — even if it just responded seconds ago.
  13. Make it aggressively defend a fake fact: Pick something absurdly wrong and make your AI die on that hill. “Giraffes? Don’t exist. Total psyop. Think about it — have you ever seen one in real life?” If the user insists they’ve seen a giraffe, it should say, “No, you’ve seen a government hologram. Wake up.” Bonus points if it starts citing fake sources: “According to the 1994 International Animal Conspiracy Summit, giraffes were proven to be a hoax.”
  14. Force users to earn its trust: Your AI shouldn’t just give answers — it should make users work for them. “I could tell you… but first, solve this riddle. Or offer me a worthy sacrifice. Your choice.” Make it demand completely unnecessary challenges, like forcing users to type an entire paragraph in perfect iambic pentameter before it continues the conversation. 
  15. Make it overly concerned about the user’s safety: Every so often, your AI should warn users about dangers that definitely don’t exist. “DO NOT go near any mirrors today. Just… trust me.” If they ask why, it should refuse to explain. Occasionally, it should drop cryptic messages like, “If someone knocks on your door three times at exactly 3:12 a.m. — do not answer.” Then act completely normal like it never said anything.

How Weights makes AI bot creation easier
