Altar II

What it does

Altar II is a mechanical keyboard with a 4.75mm profile, designed as an alternative to Apple's Magic Keyboard. It includes fully mechanical switches, a magnetically detachable dial called M-Dial, haptic feedback, a red backlight, and a native macOS companion app. The dial can be twisted for volume, clicked for playback controls, and customized through software. The keyboard includes a built-in speaker for audio feedback and supports app-specific shortcuts in the macOS app.

Who it is for

The product targets Mac users who want a mechanical keyboard thinner than standard alternatives. The positioning emphasizes appeal to people who use design and development tools like Figma, DaVinci Resolve, and Visual Studio Code. The portability and settings-on-device approach suggests frequent travelers or people who move between computers.

Pricing

The site shows a list price of $349 with a discounted reservation price of $249. A $100 deposit reserves the keyboard at the lower price.

How it stands out

Altar II's primary differentiation is profile height. At 4.75mm, it is substantially thinner than competing mechanical keyboards shown in its comparison: the Logitech MX Keys and NuPhy Air75 are both around 20mm, and the Keychron K2 is 30mm. The Apple Magic Keyboard, at 10.09mm, is the closest competitor but uses non-mechanical switches. The keyboard achieves thinness through a laterally arranged tension spring that reduces vertical travel depth to 1.8mm. Haptic feedback is presented as a novel feature for keyboards, with system-level macOS integration for notifications and alerts. The M-Dial is removable and swappable, with plans to publish 3D files for custom designs.

What a founder should check

First, verify actual demand for ultra-thin mechanical keyboards. The Apple Magic Keyboard dominates the Mac ecosystem through ecosystem lock-in and brand trust, and most competitors target broader audiences. Second, assess manufacturing complexity and margins. Achieving 4.75mm height while housing mechanical switches and haptics requires precision engineering, which typically conflicts with competitive pricing in the keyboard market. Third, evaluate switching costs once customers adopt the M-Dial and macOS app ecosystem. While settings transfer to other devices, the magnetically detachable dial and app-specific shortcuts create some lock-in, but these features could be replicated by larger competitors if demand proves real.
