AI companion robots, explained: what the AI actually does. Offbrand Human

"AI companion robot" is doing a lot of work in the marketing copy. The same four words get slapped on a $60 desk toy and a $3,700 plush. Underneath them sit three completely different machines, and knowing which one you are looking at decides whether you are buying a chatbot with a face, a reactive emotive toy, or a small animal that runs on scripts.

The tier map

Sort by what is actually happening when the robot seems alive.

Tier	What the "AI" actually is	Examples	Recurring cost
Talks back (language model)	Cloud LLM for real conversation, needs WiFi	Loona Petbot, EBO X, Miko 3, Eiliko, LOOI	Sometimes (see below)
Reacts, does not converse	Scripted expressions, sensors, "personality" that evolves by rule	Eilik, EMO, Vector 2.0, Casio Moflin	Sometimes (Vector)
Bonds, does no tasks	Emotional-response engine, touch and movement, no chat	LOVOT, Nicobo	Yes, mandatory (LOVOT, Nicobo)

You want to know which bucket a robot is in before you fall for a demo video. A robot that "talks" and a robot that "reacts" feel very different on day thirty.

Tier 1: the ones that actually run a language model

These connect to WiFi and route your speech to a cloud model, so you get open-ended conversation instead of a fixed menu.

Loona Petbot ($499 at keyirobot.com) runs ChatGPT-powered conversation and storytelling, recognizes family faces, and localizes your voice to turn toward you. It is the closest thing here to "a pet that can hold a conversation."
EBO X ($799 on sale from $999 at Enabot, currently out of stock) uses GPT-4o mini for voice, adds a 4K camera, Alexa, and elderly fall detection. It is a companion robot wearing a home-security robot's body.
Miko 3 ($299) is a kids' conversational robot, ages 5 to 10, with moderated COPPA-compliant chat. Real language model, deliberately fenced in.
Eiliko ($59.90 on sale, normally $69.90) is the surprise: the cheap sibling of Eilik connects to 2.4G WiFi for an "AI brain" chat feature the original Eilik does not have.
LOOI ($239 at looirobot.com as of August 2026, marked down from $259; the ~$179 you may have seen was Kickstarter pricing) is a dock that turns your phone into the robot. Your phone is the brain, so the compute is borrowed. It advertises on-device emphasis ("data will not be sent to the cloud"), which is unusual for this tier.

The catch with Tier 1 (LOOI and its borrowed phone brain aside): no WiFi, no smarts. The language model lives on someone else's server, which is a fine trade until that server is the thing that breaks.

Tier 2: "AI" that is really scripted reaction

This is the biggest and most misunderstood group. These robots feel alive, but the aliveness is animation and sensor rules, not conversation.

Eilik ($139.99, marked down from $149.99) is the breakout desk companion: a reactive emotive toy that runs fully offline, no WiFi, no account. It reacts to touch and idle time (spontaneous expressions after a minute, sleep after fifteen), and multiple Eiliks recognize each other and play or "fight." It is not an assistant. Nobody serious pretends it is.
EMO ($279 from Living AI) roams your desk on its own, has 1,000-plus expressions, recognizes up to 10 faces, and evolves a "personality." That personality is a behavior model, not a chatbot. It is cloud and app dependent, which matters for how long it lives (more on that below).
Vector 2.0 ($199.99 base at anki.bot) has a persistent personality, Alexa built in, face recognition, and cloud AI for voice queries. It roams, reacts, and plays with its cube. Charming in every owner video, genuinely cloud-tethered.
Casio Moflin ($429 in the US, sold by Casio America) is the one with no face and no screen. Its whole pitch is an emotional AI that grows a unique personality from how you handle it, expressed only through movement and sound. Designed to be held, not talked to.

Two white-and-teal Eiliks staged on white pedestals in a red miniature art room, one beside a wooden easel and one propped up with a violin, three tiny framed paintings on the wall behind them: the scene is set dressing, and the only thing either robot is actually doing is changing the expression on its screen. — Energize Lab's own studio set.

Day thirty with any of these looks the same. The robot reacts, you narrate the rest. What you have is a relationship with a very good animatronic.

Chart headed 'What AI means in a companion robot,' sorting the field into three tiers, each row carrying a photo of one robot from that tier. Talks back, runs a cloud LLM, $59.90 to $799: Loona, EBO X (pictured), Miko 3 and Eiliko, with LOOI using your phone as the brain, and no WiFi meaning no smarts. Reacts, scripted rather than chat, $139.99 to $429: Eilik (pictured), EMO, Vector 2.0 whose voice AI costs $11.99 a month, and Moflin. Bonds, does no tasks: LOVOT and Nicobo (pictured), Japan only, fees mandatory at 9,900 yen a month and up for LOVOT and 1,100 yen for Nicobo.

Tier 3: bonds with you, does nothing useful

Both entries here are Japanese companion robots, and neither is sold in the US.

LOVOT 3.0 (from 577,500 yen, roughly $3,700, Japan only) is the high end of pure companionship. It recognizes and remembers each family member, seeks attention, responds to touch, and explicitly performs no tasks. Groove X cites cortisol-reduction studies. It is the proof-of-concept that emotional robots can bond, and it is not sold in the US.
Nicobo (Panasonic, Japan only: 60,500 yen at its 2023 general launch, per press coverage, plus a required 1,100 yen a month to keep it updated) is the budget cousin: a squishy, tailed thing that mumbles baby-talk and slowly grows attached to you. It is designed to be useless on purpose, and that monthly fee is not optional.

The subscription reality nobody puts on the box

The demo videos skip this part. Some of these robots stop being what you bought the day you stop paying.

Vector 2.0: the base robot is $199.99, but its cloud voice AI runs on an $11.99/month or $99.99/year subscription. The personality robot's smarts are paywalled and cloud-tethered. Digital Dream Labs has a long community record of missed timelines and server-reliability worries, which is exactly why an offline "Escape Pod" option exists. Before you buy one, decide how you feel about the day those servers go dark.
Miko 3: $299 gets you the hardware, but much of the value (Disney content, Story Maker, enhanced parental controls) sits behind Miko Max, from $8.25/month billed annually ($99/year, regular $180) or $14.99 month to month. Well-reviewed hardware, relentless upsell.
LOVOT: ownership itself is a subscription. A mandatory care plan runs from 9,900 yen/month up to 19,800 yen/month, which makes the 577,500 yen sticker a deposit on a dependent. (Nicobo, its budget cousin, plays the same game in miniature: 1,100 yen a month, mandatory.)
Loona: its own FAQ asks "Will Loona charge for ChatGPT 4o function?" and answers that it is free "for the moment." No fee today, an explicit hedge for tomorrow. If the free AI is why you are buying, know that KEYi has left the door open to charging later.
Free and clear: Eilik, Eiliko, EMO, and LOOI advertise no mandatory subscription. EMO carries a different risk: it is cloud and app dependent, so its lifespan is tied to Living AI staying in business. No fee, but not fully in your hands either.

The day the servers go dark is not a thought experiment for this robot. It already happened once: "Anki's servers died in 2019," as one owner puts it, and the hardware outlived them.

The clearest answer to "what happens when the cloud behind a personality robot goes away," from someone whose Vector is still running long after the company that built it stopped.

What to buy, and what to check before you pay

If conversation is the point, you are shopping Tier 1, and a cloud dependency comes with it. For a charming desk creature with no monthly bill, buy Eilik, or EMO if you can live with its cloud tie. Past that, a premium "AI companion" price tag deserves two checks before you pay it: whether the intelligence lives on a server you do not control, and whether it keeps charging you. Both answers are usually in the fine print.
