Hardware startup Aina has launched its flagship wearable, an AI-focused smart ring equipped with a tiny display, a miniature joystick, a microphone, and a speaker. Positioned as a physical controller for both software applications and artificial intelligence agents, the device aims to offer a direct interface for users managing proactive software across their computers and smartphones.
The announcement comes as hardware makers experiment with dedicated devices tailored for AI interactions. Aina, which raised $5.5 million in funding in July, previously developed Mirage, a three-key physical controller designed to trigger context-aware actions based on active desktop applications. The new smart ring expands on that concept, bringing desktop control and voice-driven AI interactions into a wearable form factor.
Navigation, Voice Input, and Desktop Control
Unlike traditional smart rings focused primarily on health metrics and fitness tracking, Aina's wearable incorporates hardware components designed for active software control. The ring features a small built-in screen that displays smartphone notifications and indicates which application or AI agent is currently active.
For input and interaction, the hardware relies on three core mechanisms:
- Voice interaction: Built-in microphones allow users to dictate notes, set reminders, and issue prompts directly to AI agents. Voice input can interface with Mac applications using either Aina's proprietary dictation engine or Wispr Flow.
- Physical navigation: A micro-joystick provides direct manual navigation through menus and settings without requiring users to reach for their phone or laptop.
- Gesture controls: Integrated sensors detect hand movements, enabling custom gesture triggers mapped to specific desktop or mobile applications.
The ring also includes an onboard speaker, allowing users to take phone calls directly from their finger. Beyond AI interactions, the device functions as a compact peripheral capable of controlling music playback, operating smart home devices such as Apple TV, managing desktop notifications, and calling rides through services like Uber.
Rethinking Hardware Interfaces for the AI Era
As software development shifts toward autonomous and proactive AI agents, hardware developers are rethinking how users monitor and direct these automated tools. Standard inputs like keyboards, touchscreens, and trackpads were designed primarily for manual browsing and app launching rather than continuous engagement with active AI software.
"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," said Apoorv Shankar, founder of Aina.
Aina joins a growing list of companies attempting to build specialized hardware for AI workflows. The market for AI-oriented peripheral hardware has expanded rapidly, with devices ranging from dedicated note-taking rings like the Pebble Index 01, Sandbar Stream, and Natura, to experimental coding tools like OpenAI's developer keyboard and Rabbit's handheld hardware controllers. Aina's addition of a display, speaker, and tactile joystick represents an effort to differentiate its hardware from wearables that rely solely on audio recording.
Pricing and Availability
Pre-orders for the Aina smart ring open at an early-bird price of $399. Following the initial pre-order window, the regular retail price will increase to $499. The startup plans to begin shipping completed units to early backers in January 2027.
While the software ecosystem supporting continuous AI agent interaction is still maturing, hardware developments like Aina's highlight a broader push toward physical, multi-modal interfaces designed to complement automated software tools.
