HiYo

Chat anonymously with anyone on the same website in real time — plus detect AI-generated text with a built-in on-device AI detector. Ever wished you could talk to other people browsing the same website as you — right now, in real time? HiYo makes it happen. HiYo is a free Chrome extension that adds an anonymous chatroom to every website you visit. No sign-up. No email. No passwords. Just pick a username and start talking. Whether you're reading the news, watching a video, shopping online, or browsing Reddit — if someone else on that page has HiYo installed, you can chat with them instantly. It's like having a secret chatroom hidden on every corner of the internet. HiYo places a lightweight chat widget on every webpage. Open it with a keyboard shortcut or by hovering near the corner of the page. Messages are delivered instantly — no delays, no refreshing. You'll see who's online, who's typing, and new messages as they arrive. Chat about the article you're both reading. Ask a question about the product you're looking at. React to the video you're both watching. Share a tip on the forum you're browsing. The conversations are as spontaneous and real as the internet itself. • Real-time messaging — messages appear instantly • See how many people are on the same website as you • "Someone is typing..." indicator so conversations feel alive • Works on every website — news, social media, shopping, forums, videos, blogs, and more • Lightweight and non-invasive — the chat hides away when you're not using it 🏠 PRIVATE ROOMS — YOUR OWN SECRET SPACE Sometimes you don't want to chat with everyone. HiYo lets you create private rooms on any website with a unique invite code. Share the code with your friends, classmates, or coworkers, and only they can join. Perfect for: • Study groups — discuss assignments together while browsing course material • Shopping with friends — compare products on the same page in real time • Work teams — collaborate on research without leaving the webpage • Watch parties — react together while streaming the same video • Gaming communities — chat on game wikis and forums with your squad Creating a room takes two seconds. Just click, name your room, and share the code. No apps to install, no links to open — just a code and you're in. Not sure if that article, essay, review, or comment was written by a human or generated by AI? HiYo includes a powerful AI content detector built right into your browser. Select any text on a webpage, right-click, and choose "Detect AI — HiYo." In seconds, you'll see a probability score telling you how likely the text is to be AI-generated. • It runs entirely on your device — your text is never sent to any server • Combines statistical analysis with a machine learning model for higher accuracy • Works offline after the first setup • No subscriptions, no limits, no per-scan fees — completely free, forever • No data collection — what you scan stays on your machine Whether you're a teacher checking student essays, a reader verifying news articles, a recruiter reviewing cover letters, or just curious about the content you're reading — HiYo's AI detector has you covered. Express yourself with emojis. HiYo includes a built-in emoji picker so you can react, respond, and add personality to your messages. Click the emoji button, pick your favorite, and send. ⌨️ KEYBOARD SHORTCUTS FOR POWER USERS • Ctrl+Shift+H (Cmd+Shift+H on Mac) — Toggle the chatbox open/closed • Esc — Close the chatbox • Enter — Send your message • Right-click selected text — AI detection No need to click around.
