Gecko is a hands-free stream deck. Give a thumbs-up and a GIF drops in. Smile and confetti fires. Clap and the last 30 seconds save as a clip — no keyboard, no fumbling, no cloud.

Build a deck of keys, bind each one to a trigger and a stack of actions, then go live. That's the whole app.
Drag actions onto a Stream Deck-style grid. Each key is a preset: a trigger, the actions it fires, and its own cooldown. Organize across pages, search your library, tweak anything.
Pick a gesture, expression, sound, hotkey, or timer. Set a confidence threshold, hold-to-confirm frames, and per-key cooldowns so effects fire when you mean it — and only then. Stack multiple actions with per-action delays to choreograph a sequence.
Switch to live mode and just… stream. Gecko watches your camera and mic, fires your presets in under 300 ms, and burns every effect straight into your recording. Tap any key to fire it manually.
Seven kinds of triggers, nine kinds of actions, any combination.
Thumbs up/down, open palm, fist, victory, point, ILY — plus any gesture you teach it yourself.
Smile, mouth open, eyebrows raised, pucker. Nod or shake your head to trigger too.
Clap or yell past a loudness threshold, or press a hotkey — global hotkeys work even while your game is focused.
GIFs, images, video, and styled text pills — positioned, sized, and timed however you like.
Fire SFX mixed into your recording, speak text aloud, or mute/unmute your mic on cue.
Start, stop, or toggle recording; save the last ~30 seconds as an instant replay clip; screen shake, flash, freeze-frame, counters.
The built-in seven not enough? Show your hand to the camera, hold the pose for three seconds, give it a name — done. Your gestures appear right next to the built-ins, work with either hand, and don't care where in the frame your hand is.
Upload GIFs, animated WebP, images, video, and sounds into a searchable library, then drop them onto any key. Preview everything in place. Animated GIFs actually animate — frames are pre-decoded so they play smoothly on the canvas and in recordings.
Streaming through OBS? Gecko ships a browser-source overlay and streams the composited preview over WebRTC, so your effects land in your existing scene.
Gesture and face detection run on-device via MediaPipe (WASM, GPU-accelerated). The models ship inside the app — no downloads on first run, no account, no telemetry, no cloud. Unplug the internet and Gecko doesn't notice.
Native desktop app with OS-global hotkeys and local file storage. Install, allow camera + mic, hold up a thumbs-up.
