Mantle Chat

Mantle Chat is an AI-powered collaboration platform that lets teams work with AI together—in the same chat, at the same time. They support GPT-5, Claude, Gemini, and other major models all in one interface, so teams can swap between AIs depending on what they're working on. It's basically Slack meets ChatGPT meets a multiplayer game where everyone's driving the AI together. Collaboration in AI tools has mostly been solitary—you ping something to an AI, it replies, repeat. Mantle Chat flips that: multiple people can canvas an AI simultaneously, see each other's inputs, build on ideas collectively. Whether you're drafting strategy, debugging code, or brainstorming product direction, the whole team can work the AI in real-time rather than taking turns in a slow prompt-response loop. It's still early innings—they just launched on Product Hunt—but the premise hits different. Every team's trying to figure out how to actually use AI as a group, not just as individuals copying and pasting outputs back and forth. Mantle Chat is building the collaborative layer that everyone else is still talking about.
