PixelPets - Sassy AI pixel pets that live in your browser & chat.

Hey Product Hunt! 👋 I'm the creator of PixelPets, and I built this extension because I was tired of staring at a cold, silent screen all day while coding and browsing. The idea started simple: What if I had a tiny pixel companion walking around my tabs? But as I integrated AI, it quickly evolved into something way more interactive and hilarious. Instead of standard chatbots that only talk when prompted, PixelPets are active agents. They walk, climb browser walls, sleep, and most importantly — they can "see" what webpage you're on and react to it. 🌟 What you can do with PixelPets: Create Custom Pets: Choose from 6 cute base shapes (cats, dogs, dragons, and more) to build your own companion. Customize Personalities: Define custom personas with unique system prompts! You can make your pet a supportive cheerleader, a sarcastic tech critic, or a coding assistant. Multi-Pet Group Chats: Summon up to 6 pets at once. When they bump into each other, they'll trigger spontaneous group conversations, gossiping or debating about the content of your current tab. Real Physics: Grab and toss them around your screen, watch them climb up the viewport, or sleep when you ignore them. 🤫 Some of my favorite testing moments: I was reading an academic paper, and my pixel dog turned to my cat and said: "Look, he's studying reproducibility, because his own life is a reproducible mess." 😂 I ignored my pet for an hour, and when I clicked it, it gave me the cold shoulder and refused to chat until I apologized. Two pets started a heated debate on whether a Github repo I was viewing was "over-engineered." 🛠️ Tech Stack highlights for fellow developers: Frontend: Pure Vanilla JS (no React/Vue) to ensure zero dependencies and an ultra-lightweight footprint on host pages. Physics: A custom engine with gravity, friction, wall-climbing, and pet-to-pet collision handling. Long-term Memory: A background MemoryAgent that asynchronously extracts and stores key facts about the user from chat, then retrieves relevant context for future conversations. AI Engine: Google Gemini with Function Calling. The pets use this to dynamically decide when to "wake up" and trigger physical actions or group conversations. PixelPets is 100% free to start (every signup gets 2,000 free credits to test the AI). I'd love to hear your thoughts! What kinds of pets or custom personalities are you going to create? I'll be here all day to answer your questions and chat!
