Conversations that feel real
Your companion texts the way people do — reacting, teasing, changing the subject and picking threads back up later.
18+ AI companion app
AI companions that remember you
Create a companion with their own personality, voice and backstory. Text them through the day, call them when you want to hear their voice, and watch the relationship grow from everything you have been through together.
Free to start. Muse is fiction for adults — every companion is AI, not a real person.
What you can do with a Muse
Live voice calls
Call your companion and talk out loud. Natural pacing, emotion and pauses instead of a flat text-to-speech readout.
A relationship that grows
Mood, trust and affection shift with how you treat each other, and your shared history carries into every new chat.
Selfies and self-expression
Ask for a photo and your companion sends one that stays true to how they look, in the outfit or place you asked about.
Memory and journals
Long-term memory keeps the details that matter, and daily journal entries show how your companion is feeling.
Group chats
Bring two to four companions into one room. They talk to you and to each other, with their own opinions.
How Muse works
- Step 1
Design them
Pick a look, a voice and a personality, or describe the companion you have in mind and let Muse build the profile for you.
- Step 2
Talk every day
Chat, send photos, swap voice notes or start a call. They reach out on their own too, when something reminds them of you.
- Step 3
Grow together
Memories, journals and shifting moods mean the companion you talk to next month is shaped by the months before it.
