Aina's $399 AI Ring Puts a Screen, Joystick and Mic on Your Finger

Hardware startup Aina launched a $399 smart ring today that packs a screen, a joystick, a microphone and a speaker — enough hardware to take calls, dictate notes and talk to AI agents without touching your phone.

The device, simply called the "AI ring," goes on pre-order Thursday at early-bird pricing of $399, with shipping planned for January 2027. That's roughly the price of a mid-range smartwatch, squeezed onto a finger.

Aina isn't starting from scratch. The startup raised $5.5 million in July, and it previously built Mirage, a three-key controller for the Mac. Mirage let you map physical buttons to whatever was on your screen — camera off and mic mute on a Google Meet call, for example, or leaving the meeting with one press.

The ring bakes those lessons into a wearable. Using its mic, you can take notes, send prompts to agents, set reminders and dictate text on your Mac through Wispr Flow or Aina's own dictation engine.

Why a screen and a joystick on a ring?

The smart ring market already has players doing pieces of this — the Pebble Index 01, Sandbar Stream, Oasis and Natura. That crowded field is likely why Aina loaded its ring with more controls than the competition.

The screen shows notifications from your phone and tells you which apps you're controlling. The speaker lets you take calls on the ring itself. The joystick handles navigation, and the device also supports gestures that trigger different actions based on what's on your Mac or phone screen. It controls music and smart home devices too, including Apple TV.

TechCrunch, which tested the ring for a few days, described it as "a smartwatch in a ring format with more controls." The reviewer could read notifications and reply to them, see upcoming meetings, and even call an Uber for a ride home.

The Apple TV use case is telling: the reviewer found the actual remote easier to use, but the ring proved handy the couple of times the remote went missing. A lot of the software and features are still being fleshed out, the review noted, making it hard to place the device firmly in a daily routine.

What does this change for AI power users?

Apoorv Shankar, Aina's founder, argues the ring targets a specific gap: the interfaces we all use were built for a different era of computing.

"Phones and laptop screens were designed for an age of browsing where you think about opening apps. For interacting with proactive agents, we need a better interface, and that is what we had in mind while designing Aina," Shankar told TechCrunch over a call.

Aina isn't alone in betting that AI-heavy users will pay for dedicated hardware. OpenAI has an experimental keyboard, and Rabbit has positioned itself as a controller for AI services. The shared thesis: once enough people run multiple agents at once, they'll buy a specific gadget to keep tabs on them all.

For practitioners — developers, AI enthusiasts, anyone juggling agents and apps across devices — Aina's pitch is a finger-level command layer. You get context-aware controls, voice input and call handling without pulling out a phone or opening a laptop.

The open question is whether a $399 ring beats the phone already in your pocket. Aina won't answer that until shipping starts in January 2027, and by then the agent-hardware field will likely be more crowded than it is today.

The early-bird pre-order window gives the startup a read on demand before that competition arrives. If the agent thesis holds, a screen-and-joystick ring could be the first genuinely new input device category since the smartwatch.
