The consumer technology landscape is undergoing a massive shift as a new wave of artificial intelligence-powered gadgets attempts to integrate machine learning directly into our daily routines. Ranging from discreet necklaces, rings, and wristbands to pocket-sized portable hardware, these devices represent a broad spectrum of philosophy in the tech industry. Some are engineered strictly as utilitarian productivity tools meant to streamline professional workflows, while others are marketed as empathetic companions designed to listen closely to everyday thoughts, monitor emotional states, and offer constant conversational engagement. Even industry giants like OpenAI are reportedly working on compact AI companion hardware to capture a share of this emerging market.
This hardware boom reflects a growing consumer desire to bypass the friction of pulling out a smartphone for routine digital tasks. However, it also introduces complex questions regarding privacy, surveillance, and the psychological impact of living life tethered to an always-listening machine. A closer look at the most notable devices reveals how startups and tech conglomerates alike are approaching the personal AI category.
Bee
Among the most affordable and actively evolving entries in the market is Bee, a $49.99 pendant that can be clipped to clothing or worn like a fitness band. Designed to record everything it hears, the device learns individual routines and preferences to generate automated reminders and notes. For privacy-conscious users, the hardware includes a physical mute button to temporarily suspend recording.
Interaction with Bee is primarily handled through a companion app—currently available exclusively on iOS—which is bundled with a $19 monthly subscription. Users can query Bee directly, review chronological transcripts of their conversations, and extract daily key takeaways. The project experienced a major corporate shift when Amazon acquired the wearables startup in July 2025, paving the way for the tech giant to launch its own hardware iterations.
Expanding the product line, Amazon introduced the Bee Frontier, priced at $74.99, which offers flexible wearability on the wrist or as a clothing clip, alongside the Bee Eclipse, a $99.99 credit-card-sized device designed to attach magnetically to the back of a smartphone. Both new models retain the core functionality of the original generation, positioning Bee as a direct, cost-effective alternative to established productivity tools like the Plaud Note and Plaud NotePin. Users also retain the option to integrate Bee directly with Alexa.
Friend
In stark contrast to productivity-focused pendants, Friend has emerged as one of the most widely discussed and controversial entrants in the personal AI space. Backed by prominent figures from Solana, Perplexity, and ZFellows, the $129 white pendant is worn around the neck and marketed as an emotional support companion. The device is programmed to recognize the user’s tone and mood, enabling open-ended conversation designed to mimic a human friendship.
Connecting to a smartphone via Bluetooth, Friend constantly listens in the background, ready to respond or send proactive messages, such as offering words of encouragement before a job interview. Despite its high-profile backing, the device has faced significant public scrutiny. Its high-profile New York City subway advertising campaign, which cost over $1 million, drew fierce local backlash, with commuters vandalizing ads and scrawling messages denouncing the hardware as a symbol of surveillance capitalism.
Seeking to maintain momentum and cultural relevance, the company launched a major product update known as "Friend 2.0." This iteration introduces a built-in speaker and an updated voice feature, allowing the device to communicate audibly with users while expressing a more distinct conversational personality, albeit alongside a higher price tag.
Limitless
Formerly operating under the name Rewind, Limitless is a conversation-recording pendant priced at $99 that targets a strictly professional demographic. Backed by venture capital firm Andreessen Horowitz, the device is built to continuously listen to and transcribe meetings, phone calls, and casual discussions—with explicit consent—transforming spoken words into searchable and summarized knowledge bases.
The accompanying software ecosystem provides 10 hours of AI-driven features per month, including automated transcription and concise summaries. For heavy users, an optional $29 monthly subscription unlocks unlimited processing capabilities. The device has found a particularly strong foothold among professionals, including journalists and researchers who rely on accurate, searchable records of daily discussions.
Muse Charm
Meta entered the hardware conversation in September by introducing its first AI wearable, designed to provide physical access to its proprietary personal AI assistant, Muse. While the device has not yet begun shipping, it is designed around Jolly, a playful digital avatar that represents the AI assistant visually.
Housed in a compact, pocket-sized form factor that can be carried in a pocket or attached to a keychain, the wearable features a miniature display screen to show the avatar’s animations. Users will be able to issue voice commands directly to the device, allowing Muse to execute tasks and assist with digital workflows on the go.
Nirva
Focusing on personal growth rather than meeting transcriptions or productivity metrics, Nirva is a startup founded by former employees of Meta Reality Labs. The company developed an AI wearable designed to turn everyday spoken experiences into a personal journal, helping users gain deeper insights into their emotions, communication habits, and behavioral patterns.
Worn as a pendant or bracelet, the device listens to the wearer throughout the day. Through a companion mobile app, users can review analytical breakdowns of their communication styles and discover constructive ways to improve their interpersonal interactions. Nirva scheduled its initial order window with shipments targeted for the end of the year, backed by $33 million in funding and a retail price of $249.
Omi
Priced at $89, Omi bridges the gap between productivity assistant and personal companion. The device is capable of answering questions, summarizing conversations, generating to-do lists, and managing schedules. By continuously listening and routing conversations through ChatGPT, Omi builds long-term context about the user to deliver highly personalized advice.
Beyond its standard use as a necklace, Omi offers a unique mounting option: it can be attached to the side of the user’s head using medical tape, featuring built-in detection to recognize when the user is speaking directly to it.
Plaud’s NotePin
Positioned at the higher end of the productivity market with a price tag of $159, Plaud’s NotePin is built specifically for intensive note-taking. Offering robust AI transcription and summarization features, the tiny voice recorder has found a dedicated following among lawyers, students, and journalists navigating heavy lecture and meeting schedules.
The hardware can be worn on the wrist or attached magnetically to clothing, capturing audio in real time and syncing recordings directly to a smartphone app to eliminate manual transcription tasks. The standard software tier includes 300 free monthly transcription minutes, which can be expanded to 1,200 minutes via an $8.33 monthly Pro plan. The company is also expanding its hardware lineup with the upcoming release of the Plaud Note Pro, an ultra-thin note-taking device available for preorder at $179.
Rabbit R1
The Rabbit R1 occupies a unique space as a standalone, retro-styled handheld device equipped with a touchscreen and a rotating camera, retailing at $199. Designed to act as a phone-adjacent companion, the R1 aims to let users handle tasks like booking flights, ordering food, and controlling applications without unlocking a smartphone.
Despite facing considerable technical and performance hurdles during its initial launch, subsequent software updates addressed critical bugs and expanded the device’s feature set. Among the updates is a feature called "Creations," which allows users to build custom digital tools and games directly on the platform.
Sandbar
Emerging from stealth mode with a Series A funding round, Sandbar introduced the Stream ring, an AI-powered wearable dedicated primarily to ambient note-taking. The ring features an integrated microphone that remains disabled by default, ensuring privacy until activated by the user via a flat, touch-sensitive panel located on the upper surface of the band.
By pressing and holding the touch panel, users can record voice notes, interact with an AI assistant through a companion mobile app, and control media playback functions such as volume adjustment, track skipping, and playback pausing. The Stream ring is slated for a summer release with a retail price of $299, offering both silver and gold finishes.
