+# KoalaSync — Marketing Copy Kit
+
+Ready-to-paste copy for product listings, launch pages, directory submissions, and anywhere else you keep re-typing the same pitch. Three lengths, one consistent message. Pick the one that fits the field limit.
+

+
+## 1. One-Sentence Pitch
+
+> KoalaSync is a privacy-first browser extension that synchronizes video playback across almost any website so you can watch with friends in real time — no accounts, no tracking, and your video never passes through anyone's server but the original site's.
+
+**Shorter alternative** (for tight tagline fields):
+
+> Private, universal watch parties on any website — no accounts, no tracking, no media proxying.
+
+---
+
+## 2. Three-Sentence Overview
+
+> KoalaSync is a lightweight browser extension that keeps you and your friends perfectly in sync on YouTube, Netflix, Twitch, Prime Video, Jellyfin, Emby, and almost any other site with an HTML5 video player — press play once and everyone stays together. It's built privacy-first: no accounts, no telemetry, and the official relay server runs entirely in volatile RAM with zero persistence, so nothing about your sessions is ever stored. Open source under the MIT license and fully self-hostable with a single Docker command, KoalaSync is a transparent watch-party tool that works everywhere and respects your data sovereignty.

+
+## 3. Full Description
+
+### Watch together — on any site, on your terms.
+
+Counting down "3, 2, 1, play" over voice chat doesn't scale past two people. KoalaSync fixes that with a tiny browser extension that synchronizes play, pause, and seeking across everyone in the room, on almost any website with a `<video>` element. Create a room, share a link, press play — that's it.
+
+### What makes KoalaSync different
+
+Most watch-party tools fall into one of two traps: they only work on a short allowlist of sites (site-specific extensions that need a separate build for every platform), or they route your video through their own player and servers. KoalaSync was built around three principles that break that mold.
+
+**Universal by design.** If the site has an HTML5 `<video>` element, KoalaSync can usually sync it. YouTube, Netflix, Twitch, Prime Video, Disney+, Jellyfin, Emby, and countless niche sites work out of the box — no per-site integration to wait for, no extension swap when your friends want to switch services.
+
+**Your video never touches our servers.** KoalaSync only relays tiny timing messages — play, pause, seek position, readiness — over a hand-rolled WebSocket protocol. The actual video keeps streaming directly from the original site to each viewer's browser. KoalaSync never proxies, transcodes, uploads, or redistributes a single frame, which also means there is no legal gray zone around redistribution.
+
+**Privacy is the default, not an upgrade.** No accounts, no emails, no telemetry, no analytics, no behavior profiling. The official relay server runs entirely in volatile RAM and keeps zero persistent state — when the room closes, the data is gone. Pick a nickname or let KoalaSync generate one for you and you're in.
+
+### Built for people who actually want to read the code
+
+KoalaSync is MIT-licensed open source, built by a solo developer. Audit it, fork it, change it. The extension is dependency-free with a direct Socket.IO wire implementation — no opaque libraries, no framework bloat, no surprise third-party SDKs. Want full sovereignty? Self-host your own relay with a single Docker command and keep all watch-party coordination traffic inside your own infrastructure. The official public relay is there when you don't care, self-hosting is there when you do.
+
+### Little touches you'll notice
+
+- **Episode Auto-Sync** pauses the room when someone loads the next episode and resumes only when everyone is ready — no spoilers, no one left behind on the previous cliffhanger.
+- **Smart Audio Compressor** tames the modern "whisper dialogue, deafening explosion" mix with one click. Three presets or full manual control over threshold, ratio, attack, and release.
+- **One-click invite links** auto-configure the server and room for your friends — they just click the link and they're in. No fumbling with server URLs or room IDs.
+- **Dual-heartbeat architecture** kills ghost rooms and stale connections before they desync your session.
+- **15 languages** fully translated and switchable in real time from the settings panel — English, German, French, Spanish, Portuguese (Brazil + European), Russian, Italian, Polish, Turkish, Dutch, Japanese, Korean, Chinese, Ukrainian.
+
+### Install and start in under a minute
+
+Install KoalaSync from the Chrome Web Store or Firefox Add-ons, click "Create Room," share the invite link, and pick a video. The official relay is ready out of the box — no setup required unless you want to self-host.
