CastCraft

📖 What is CastCraft?

A free comment viewer and stream effects tool for YouTube and Twitch. First-time viewers are marked with a "NEW" label, and each viewer's chat history, notes, and visit count are automatically tracked, making it easier to call out regulars by name. It comes with everything you need: chat TTS integration with Bouyomi-chan and VOICEVOX, "Chatbox" for displaying chat in OBS, and "Screen" for on-screen effects like fireworks triggered by chat or tips. It's completely free and even has its own tipping feature with a 90% payout rate.

💡 When to Use It

Great for streams focused on viewer communication — where you want to greet every first-time viewer and remember regulars' names and visit counts to call out to them. Add chat-triggered fireworks or GIF effects on screen, and you can build audience-participation-style excitement. It also tracks which Super Chats you've already read, which helps prevent missing any.
