They let you finish

Send "hey", then "wait", then "actually…", and the cast holds off until you've stopped typing, then answers the lot in one go. No reply to every half-sentence. How long they wait is yours to set for each channel.

A cast, not a bot

Seat up to 200 characters in one channel and they take turns, answering you and arguing with each other. Each one speaks under its own name and avatar, either through a webhook or as its own Discord bot account in the member list.

They look things up

When a reply needs something current, the character searches the web itself, in character, and cites its sources under the message. Each character runs its own search, and it works on OpenRouter models, not just Gemini.

Memory that outlives the chat

Characters write long-term memories as you talk and recall them when they're relevant, up to 5,000 each. Clear the channel's conversation with /refresh and they still know who you are.

Moods that carry over

Each character has a neuro-endocrine engine: dopamine, cortisol, oxytocin and adrenaline shift as the conversation goes and change how it behaves. With Proactivity on, leave one hanging and it follows up on its own. Right-click any reply for View Generation Trace: the model and cost, the memories and sources behind it, and its chemistry at that moment.

Set up in a minute

MimicAI says hello when it joins, and /start takes you through five steps: create an account, add a key, get a character, seat it in a channel, and say something to it. It checks each step as you go, so you can always see what's left.

Make it yours

Draft a character from a concept or a picture, then review it: nothing is written until you press Save, and you can Regenerate or Refine it first. /profile manage is the dashboard for each character: persona, models, sampling, tools, memory and training. Pick any OpenRouter model with its price, context size and data retention beside it, and give each slot a fallback.

See how they think

Switch on Thought Summary and every reply arrives with the model's reasoning attached, so you can see why the character said what it did. Reasoning effort is set per model slot, so dialogue can think hard while the chores stay cheap.

Pictures, and secrets

Type !imagine and the character draws it, then reacts to it. /whisper sends one character a private message mid-scene: the rest of the cast never sees it, and only you see the reply.

Give them a voice

Switch on text-to-speech and the characters speak their replies. Choose from 30 voices, and use the Director's Desk to set the performance: archetype, accent, pacing, acoustics and vocal style.

Deal them in

/play eights seats the channel's cast at a game of Mimic Eights, a Crazy Eights variant for two to six players. Take a seat or just watch. Each character plays its own hand in its own style, its mood shifts with the cards, and the whole table has something to say when someone wins. /play dice is Liar's Dice, where a nervous character's bluffs show.

Also in the box

Your key, your data

One OpenRouter key covers everything: hundreds of models for dialogue, web search, image generation and speech, free ones included. A Google Gemini key works too, if you'd rather stay on the Gemini line. Everything you write (personas, instructions, memories and conversations) is encrypted at rest. Characters are content-rated, and adult-rated ones are kept to age-restricted channels.
