Meta executives said they were mindful that asking people to approve every small action can lead them to approve requests reflexively, undermining safety.
-
Zuckerberg said that for people not wearing smart glasses, the Charm would be by far the fastest way to talk to Muse and show it what is going on around them.
-
Abhimanyu Ghoshal argues the Charm does not need to exist as hardware: Meta should make Muse available on screens people already use, and the more Muse handles bookings, email replies and payments, the more users will want to review its actions on a decent-sized screen rather than through an animated character.
-
Reuters compared the Charm to the Rabbit R1, a handheld AI device with a screen and a button that launched in early 2024 and flopped after overpromising and delivering an unreliable experience.
-
IDC director Jitesh Ubrani said the Charm appeals to people who might not want or trust smart glasses, and speculated that such a device might run a small language model locally.
-
Linda Sui, founder of the market research firm Smart Analytics Global, said the Charm could find traction among Gen Z if affordable and easy to use, but was cautious about its mass-market potential unless it offers functions that phones, watches, earbuds or smart glasses cannot easily replace.
-
Zuckerberg said Meta had shifted its focus from the metaverse to building devices for "personal superintelligence"; Reuters framed the Charm as part of Meta's long effort to escape Apple's and Google's operating systems with a platform of its own.
-
At the time of the announcement Meta still had to finalize the Charm's components and design, had built only a few units, and said it would share more details soon.
-
Zuckerberg said the user taps the fingerprint sensor in the corner and can start talking without unlocking a phone or opening an app.
-
Zuckerberg revealed the Charm as a "one more thing" moment at Connect; the avatar is known inside Meta as Jolly; the team still had to finalize the component layout, with shipping promised in time for the December holidays.
-
Axios reported that Meta was the first large technology company to unveil plans for this new category of device, ahead of OpenAI, Apple and others working on small AI devices.
-
Muse has a free tier and two subscription options at $20 and $100 per month.
-
A separate system called Sentinel controls Muse's access to the internet and connected services, deciding whether a suggested action is allowed, blocked or sent to the user for approval; more sensitive actions require approval while previously authorized lower-risk tasks proceed.
-
The Muse agent runs on a dedicated virtual machine in Meta's cloud, private to each person but on Meta's infrastructure.
-
Meta announced Muse, a personal AI agent, on September 8, 2026. It is designed to be more proactive and long-running than typical chatbots, and was initially available in the US on iOS, Android and the web.
-
Bosworth called the Charm an exploration and a "v0", said it is not the core of Meta's AI hardware strategy, and expects far more people to use Muse through phones and glasses. The first model is aimed largely at Muse enthusiasts, and Meta is considering follow-up generations if the concept succeeds.
-
Meta has not decided the Charm's price; people familiar with the plans said it would be priced in the range of a smartwatch. Cellular carrier fees were also not finalized.
-
Meta CTO Andrew Bosworth said former Apple designers Alan Dye and Billy Sorrentino were two of the driving forces behind the Charm and its character-based interface.
-
The Charm began as a playful prototype codenamed "Clawmagochi"; Meta began looking at the concept in March 2026, originally aimed for 2027, and Zuckerberg pushed to unveil it and put it on sale in 2026. It went from initial vision to finished product in about nine months.
-
Two Charms can recognize and interact with each other when placed nearby, and the device is set up and synchronized through the Muse app on iPhone or Android.
-
People with knowledge of the device describe it as a "holdable" rather than a wearable: a small dedicated device picked up and talked to through the day.
-
The Charm can be worn on a wrist strap, carried in a pocket, or attached to a bag or keychain with a lanyard; a translucent case shows the internal circuitry.
-
The Charm has front and rear cameras intended mainly to give Muse visual information, though photos and videos can be viewed on the device; it also plays music and video and has speakers, microphones and a USB-C charging port.
-
A virtual Muse character sits at the center of the screen; users can change its appearance, outfits, voice and other attributes.
-
A built-in 5G modem lets the Charm reach Muse away from Wi-Fi; it cannot make phone or video calls, and it uses a fingerprint sensor to unlock.
-
The Muse Charm came out of Meta's new design lab, led by former Apple interface design chief Alan Dye, and Meta's Superintelligence AI group.
-
The Muse Charm has a roughly 2-inch OLED touch screen, navigated with a thumb, and runs a new operating system designed for the device.
-
In the 2023 index, overall scores ranged from 54 (Meta) to 12 (Amazon) with a mean of 37; upstream transparency (data, labor, compute) scored worst, and no company scored on indicators for data creators, data copyright and license status, or copyright mitigations.
-
An audit tracing the lineage of more than 1,800 text datasets found licence omission rates above 70% and error rates above 50% on popular dataset hosting sites.
-
In the context of AI-generated abuse imagery, malicious actors often use freely available models with safeguards removed, and could apply AI-indicating metadata or watermarks to real abuse imagery to make it less likely to be investigated.
-
Synthetic content detectors typically output a probability-like score, and false positives (human content judged AI-generated) can be extremely damaging.
-
Embedded metadata is often stripped when files are shared, and metadata generally cannot travel with raw text copied between documents or applications.
-
Provenance metadata can indicate synthetic origins or assert authenticity, and is typically embedded in the file but can also be stored in an external repository linked by an identifier.
-
Covert watermarks are designed to persist where metadata is often stripped, and watermarks carrying data could leak sensitive information about a tool's user.
-
NIST uses Executive Order 14110's definition of synthetic content.
-
Digital content transparency may contribute to trustworthiness but does not guarantee it, and can create a false sense of trust, e.g. when legitimate content is taken out of context.
-
NIST defines digital content transparency as documenting and accessing information about the origins and history of digital content.
-
Colchicine, NSAIDs or glucocorticoids are strongly recommended as first-line flare treatment over interleukin-1 inhibitors or ACTH, and topical ice is conditionally recommended as an add-on.
-
The ACR strongly recommends switching to pegloticase when xanthine oxidase inhibitors, uricosurics and other interventions have failed to reach the urate target and the patient still has frequent flares or non-resolving tophi.
-
Without crystal confirmation, the 2015 criteria score clinical features (pattern of joint involvement including the first metatarsophalangeal joint, inability to bear touch, redness, time course of episodes, tophi), serum urate, synovial fluid results, and imaging evidence of urate deposition (ultrasound double-contour sign or dual-energy CT) or gout-related joint damage.
-
Uricosuric drugs, which increase the kidneys' excretion of urate, were first used in the late 19th century; high-dose salicylates were later replaced by probenecid, sulfinpyrazone and benzbromarone.
-
Allopurinol, the first xanthine oxidase inhibitor, was developed by George Hitchings and Gertrude Elion, who shared the 1988 Nobel Prize in medicine partly for it; it became the most frequently used urate-lowering drug.
-
Colchicine, from the autumn crocus, was first used specifically for gout by Alexander of Tralles in the sixth century AD; it fell out of use under Sydenham's influence and was rediscovered in 1763 by Baron Von Stoerk.
-
McCarty and Hollander showed that crystals in gouty joint fluid were monosodium urate and introduced compensated polarized light microscopy to identify them.
-
Van Leeuwenhoek described tophus crystals in 1679; Scheele identified uric acid in a kidney stone in 1776; Wollaston found urate in a tophus in 1797; and Alfred Baring Garrod's 'thread test' measured uric acid in blood, leading him in 1859 to call deposited urate the cause of gouty inflammation.
-
Thomas Sydenham, himself disabled by gout, described a flare that wakes the patient around two in the morning with pain in the big toe that becomes so severe the patient cannot bear the weight of bedclothes.
-
Because gout was associated with rich food and alcohol that only the affluent could afford, it was called the 'disease of kings'; Hippocrates called it an 'arthritis of the rich'.
-
The word 'gout' was first used for podagra by the Dominican monk Randolphus of Bocking; it derives from Latin gutta ('drop'), reflecting the medieval belief that an excess humor dropped into the joint.
-
Podagra (acute gout of the big-toe joint) was first identified by the Egyptians in 2640 BC and later described by Hippocrates in the fifth century BC as 'the unwalkable disease'.
-
Under the 2015 ACR/EULAR criteria, finding monosodium urate crystals in a symptomatic joint, bursa or tophus is sufficient on its own to classify a person as having gout.
