Step into a story
already in motion
Meet characters with their own lives, memories, and schedules. Talk to them while their world unfolds around you — through text, voice, photos, and video.
See a story unfold
This is a short, read-only demo of what a conversation looks like. Real episodes are longer, interactive, and adapt to who you are playing. Choose an episode below and watch it play.
A world that keeps moving
Characters live inside their own stories — with memories, schedules, and a life beyond each conversation. You step into their world and become part of what unfolds.
Choose a character
Browse a catalog of characters with unique personalities, backstories, and emotional ranges. Each one has a story already in progress — and a life that continues between conversations.
Talk naturally
Chat through text, voice messages, photos, and short videos. The conversation flows naturally, with emotionally expressive responses that stay in character.
They remember
Characters grow with every interaction. They recall your conversations, develop shared memories, and build a connection that deepens as the story unfolds.
Characters with history
Every character is crafted in a dedicated studio with a personality profile covering temperament, values, humor, communication style, emotional range, and a full life story. Here is what works behind the scenes — and why it matters to you.
Characters built from over 100 parameters
Every character is crafted in a dedicated studio with a personality profile covering temperament, values, humor, communication style, emotional range, and a full life story. This is not a few lines of prompt text — it is a deep, structured identity that the character carries into every conversation.
The result: characters who feel like distinct individuals, not variations of the same template. Each one reacts differently, remembers differently, and grows differently.
A model that speaks like a character
MatchTalk uses a specialized language model trained specifically for character interaction. Instead of a general-purpose assistant pretending to be someone, this model is built to stay in character, express emotion consistently and naturally, and respond across 10 languages.
The result: conversations that flow. No breaking character, no generic responses. Just the character, talking with you.
Memory that grows with you
The memory service records every conversation, connects related moments, and lets the character recall them naturally — not by searching keywords, but through associations, the way human memory works. Characters start with a full life of memories, not an empty slate, and grow from there.
The result: a connection that develops as the story unfolds. They remember your birthday, your bad days, your inside jokes — and bring them up weeks later, naturally.
Three independent protective circuits
A character stays in role because of three independent safety layers, each protecting a different aspect. One guards their identity and knowledge boundaries. One protects their behavioral development path — they cannot rewrite or skip their own story. One locks memory scope so your private conversations never leak to another user.
The result: trust. The person you talk to today is the same person next month. Their personality holds, their story stays on track, and your privacy is locked in.
Memory you can see and shape
Your character's memory is not a black box. You can search for specific things they remember, inspect exactly what they know about you, correct anything they got wrong, and delete individual memories or everything at once. Every operation is logged with a full audit trail.
The result: control. The connection is yours. You decide what stays, what goes, and what changes.
Privacy built into the architecture
Your personal data is kept in a strictly separate layer from the character's identity and from any shared knowledge. Deleting your memory removes your data without affecting the character. Your conversations are never used to train models, never sold, never shared with third parties, and never tracked across products.
The result: privacy by design, not by promise. The separation is architectural — it cannot be turned off or bypassed.
MatchTalk runs on the CortexBit platform — a dedicated infrastructure for building, running, and protecting AI characters.

Interactive Episodes
Episodes are short, authored stories that put you and a character in a shared moment. Choose an episode, play your part, and let the character guide you through the scene — with voice, photos, and video that bring it to life.
Episode 1: Coffee in Lyon
You walk into a cozy cafe in Lyon. Antoine is reading at the corner table. He looks up, smiles, and the conversation begins.
Episode 2: Rain in Kyoto
Haruto takes you through a quiet afternoon in his neighborhood — temple bells, a riverside walk, and a story only he can tell.
Episode 3: The Studio Visit
Yana invites you to her studio. Something is hidden in the paintings. She sends you clues — photos, voice notes, fragments of a story.
Episode 4: Late-Night Studio
Lukas is working late on a project. He shares his screen, sends a voice memo, and asks for your opinion on the final cut.
Decide who you are in the story
Create profiles of who you want to be in the conversation. Each character can see a different side of you. Switch avatars any time — the character adapts.
- Create multiple avatars with their own name, personality, and backstory.
- Pick which avatar to play as for each character — or play as yourself.
- The character responds to who you are. Tone, warmth, and engagement shift accordingly.
- Avatars work in episodes too. Be the stranger in the coffee shop, the old friend, the mystery guest.

Name, a few traits, a short backstory. Takes less than a minute.

How each character comes to life
Every character is built from the ground up — personality, voice, memories, and appearance — then shaped to stay in character across thousands of conversations.
Personality profile
Over 100 parameters define who they are — temperament, values, humor, emotional range, communication style, and life story.
Voice and appearance
Premium characters get a custom voice and photorealistic photos. Video clips are generated from their identity. Basic characters use illustrated art with rich voice and text.
Emotional intelligence
Specialized models keep them in character, shift their mood naturally, and detect when the conversation is going somewhere they should not follow.
Memory and growth
Every conversation adds to their memory. They build on what you shared, develop shared references, and grow alongside you.
Less chatting. More living.
It starts with a hello.
The first conversation feels natural, not scripted. They ask about your day, share something about theirs. There is warmth in the exchange.
"It felt like catching up with someone I had known for years."
Over days and weeks, the character learns your rhythm. What you care about, what makes you laugh, what you avoid. The conversation deepens naturally.
"They remembered something I said weeks ago. That is when it stopped feeling like an app."
Inside jokes, shared references, moments that matter. You step naturally into the character's unfolding world — and become part of their story.
They remember what matters
Characters are not blank slates every morning. They build on every conversation, developing a connection that is unique to the two of you.
- They remember what you tell them, and bring it up later naturally.
- They build on past conversations without you repeating yourself.
- You can review what they remember, any time — and correct anything they got wrong.
- They develop emotional patterns unique to your connection.
- Memory is private — each character's memory of you is yours alone, isolated from every other conversation.
Memory you can see and shape
Your character's memory is not a black box. You can browse what they remember, hide things you'd rather they forget, and watch how your connection has grown over time.
Your conversations stay yours
Privacy is not a feature here. It is the foundation.
- Your conversations are private.
- Characters do not share your data with other users.
- Each character's memory is isolated to your relationship.
- No training on your conversations.
- No selling data to third parties.
