An AI companion robot for adults now means two very different products: a physical humanoid with a face, voice and moving body, or an app companion that lives on your phone and costs a monthly subscription. This page compares them using official pages only: Realbotix’s Series 1 humanoid on the hardware side, and Candy AI, Joi and Dondi.ai on the app side, all as of November 2026.
# Two categories, one question
The physical option gives presence: a body in the room, eye contact, a voice from a speaker. The app option gives breadth: many characters, images, voice and adult conversation for a small fraction of the cost. Which matters more to you decides the rest.
# The hardware option: Realbotix Series 1
Realbotix, which builds its robots in Las Vegas, sells the Series 1 humanoid in two sizes, each with a choice of four personas named Aria, Mila, Dave and Amar. According to its pricing and product pages:
- Tabletop: $11,950, 17 degrees of freedom, about 31-32 inches tall, 25 lb.
- Full-body: $59,950, 39 degrees of freedom, fully articulated fingers, a quad microphone array, stereoscopic cameras, about 72-77 inches tall, 88 lb.
- AI plan required: Base $19.99 a month for 10 hours of conversation, Plus $39.99 for 40 hours, Enterprise $199 for 100 hours, or Enterprise with Vision at $199 for unlimited hours. If hours run out, the robot is limited to basic functions.
- Optional Vinci Vision System: $24,950, which recognizes who it is speaking with and reads emotional cues; it requires the Enterprise with Vision plan.
- Buying process: a $199 deposit, 50% of the price invoiced before production and due within 30 days, the rest plus shipping before delivery. Deliveries are expected to begin in the second half of 2027, in the United States only, with 225 tabletop and 25 full-body units planned for 2027.
Realbotix lists its use cases as education, elder care, wellness (“easing loneliness”), hospitality and retail, and corporate services. It does not market Series 1 for adult content, so anyone looking at an AI companion robot for adults should read it as a conversational companion, not an intimate one. On privacy, it says Series 1 never records or stores your conversations, and that what Vinci sees stays on the robot and your phone.
# The app option: companions on your phone
App companions do not have a body, but they cover adult conversation and media that a service robot does not.
App companions like Joi live in a chat window, so there is no hardware to buy or ship.
Candy AI lets you design a companion’s appearance, voice and personality, then chat, receive images, hold voice conversations and get video, all from one token balance. It runs in the browser and can be added to your phone’s home screen. Design a companion on Candy AI.
Joi focuses on adult roleplay chat and adult-themed image generation, with filters by gender, adult age bracket and tags, and says chats can be used anonymously. Browse Joi’s companions.
Dondi.ai presents itself as an uncensored AI girlfriend site with categories such as Mature, Latin and Anime, plus image generation, character creation and voice chat in its menus. Its homepage claims more than 50 million users and was showing a timed sign-up discount. Visit Dondi.ai.

# Which one fits
- Choose hardware if presence matters most, you are in the US, and you can wait for a 2027 delivery. Expect a service-oriented personality rather than adult roleplay.
- Choose an app if you want adult conversation, images or voice now, at a predictable monthly cost. And unlike Series 1, you can start today.
- Try before buying either. Realbotix offers a free digital preview of Aria on phone or web; the apps all have free sign-ups. Start a free Candy AI account.
