PlaiiinLight is the companion app for PlaiiinLightOS — free, open‑source firmware that turns any ESP32‑based LED lamp into something you shape with a sentence. Describe a pattern in plain words — "a slow aurora," "fire crackling in the corner," "a calm blue breathing glow" — and AI writes an effect that runs right on the lamp. A live in‑app preview shows the result before you push it to the LEDs, so you can iterate without ever touching the hardware. From the dashboard, drive every lamp at a glance — set color and brightness, switch between effects, and tune each one live with on‑screen dials for speed, scale, intensity, and more. Adjust a knob and the lamp responds instantly. Stream an animated GIF straight to the lamp, frame by frame, or write your own effect in JavaScript — Manage your effects it in the app, save it to the lamp, and upload or tweak it anytime. It all runs on the device itself, not in the cloud. Turn your lamp into a pixel canvas — paint, brush, spray and fill tools, live streaming as you draw, photo import, and images you save on the lamp itself to show again anytime. Got more than one lamp? Group them into a swarm and they act as one: a color, an effect, a brightness change or a tap on Off propagates to every member instantly, lamp to lamp over your Wi‑Fi. Add or remove members anytime, and show the whole swarm as a single dashboard tile. Onboard a new PlaiiinLightOS lamp over Bluetooth, then control it over your local Wi‑Fi network. Keeping it current is effortless: the app checks for new firmware, shows a badge and installs the update over the air with one tap — no cables, no computer. Adjust the lamp's settings — name, network, MQTT, and more — right from the app. Share a lamp with family or friends by minting a share key, scanning a QR code, or handing it over via Bluetooth — no re‑pairing, with roles that keep admins, creators, and users apart. Bring your own AI provider key (Anthropic, OpenAI, or Google). It's stored only in your device's Keychain — PlaiiinLight has no account to sign up for and no servers of its own. Your lamps, your key, your light.
