Shape it on your Mac. Tap it on your iPhone and iPad.
Where it shines
A plastic button box stays wherever its USB cable reaches. Your iPhone and iPad go everywhere you do—bringing your shortcuts, a trackpad, and a keyboard along for the ride.
01 / 05
When an AI agent is writing the code, you don’t need to sit at attention. Lean back with your iPhone: tap to approve a diff, rerun the test suite, or scroll terminal output on the trackpad. Hold down a key to dictate your next instruction, or type a quick follow-up—with ready-made panels for AI chat apps and terminal agents.
02 / 05
Hook a Mac mini up to the living-room TV, a projector, or a spare monitor. Pair once at your desk, and as long as the Mac is awake on the same Wi‑Fi, your phone is its trackpad, keyboard, and media remote—nothing extra to pack or charge.
03 / 05
Folded shut, it’s a quick one-handed deck in your pocket. Unfold it, and Hotglass expands into the full iPad layout—giving your multi-key panels, wide sliders, and pinned controls room to breathe.

04 / 05
Cutting video, mixing a track, streaming, or pushing pixels? Prop your iPad beside your display instead of buying another box for your desk. Nudge timelines and brush sizes with step wheels, watch your Mac’s live system and mic volume on wide sliders, and keep a pinned trackpad right under your thumb as panels shift from app to app.
05 / 05
Step out from behind the table when you’re pitching or leading a call. Advance slides, adjust system volume, or toggle your mic from across the room—and because the mute key reflects your Mac’s live mic state, you’ll never have to ask if people can hear you.

Blade, mark in and out, and dial through frames or timeline zoom one crisp notch at a time with step wheels.

Fire off messages, insert a new line, jump into voice mode, or trigger ready-made prompts like Summarize and Polish.
Mac · Any app
Tap the top bar to pin any panel, return to following the Mac, or switch the look between Glow and Minimal.
Under the glass
Tap to fire a key chord, paste a text snippet, open an app, file, or URL, or run a macOS Shortcut. Or keep a chord held down for as long as your finger rests on the glass—perfect for push‑to‑talk dictation.
Glide the pointer, scroll, click, type on your Mac from your phone’s keyboard, or flick the joystick. Pin a trackpad to the persistent zone so it stays under your thumb on every panel.
Output and mic sliders reflect your Mac’s real volume in real time, and the mute key shows its true state. For app controls like timeline zoom, frame stepping, or brush size, step wheels send precise key presses notch by notch.
Chain a sequence of up to eight actions with timed waits in between—or set a key to toggle back and forth, pick an option at random, or run two actions at once.
Local AI tools on your Mac can design and rearrange panels for you after you approve each tool on the Mac. They can only edit layouts—they can never press a key or trigger an action.
No account, no cloud, and no analytics. Your phone never sends scripts, paths, or commands over the air—it only says which key you touched, and your Mac does the rest.
The Mac editor
Drag keys across the grid, stretch a slider, pick icons and colors, and watch your iPhone or iPad update live as you edit.
Press a shortcut once to capture it, or choose a command straight from a running app’s menu bar.
Move keys, resize controls, or swap panels freely—every change can be undone with ⌘Z.
Approve a local AI tool on your Mac to generate or tidy up a panel. It edits layouts only, never presses a key.
Your iPhone or iPad and your Mac discover each other on your local network and talk directly over an encrypted connection pinned to both devices’ cryptographic identities. When you pair, check that the six digits match, click Allow on your Mac, and they’re locked to each other—with no account, no analytics, and no server in the middle.
Free & Membership
The Mac app is always free. Membership is an In‑App Purchase in the iPhone and iPad app—available yearly or once for life at the local price shown in your App Store, with Family Sharing included on both.
Open Hotglass on your Mac, tap your Mac’s name on your iPhone or iPad, verify the six digits match, and your deck is live.
