Built for people who think better together
TandemChat started with a simple question: why do we always plan alone with AI, when the best decisions happen with other people?
Our story
Every day, millions of people use AI to plan trips, make decisions, and brainstorm ideas. But they do it alone. The people they are actually planning with are left out of the conversation entirely.
TandemChat changes that. We built a collaborative space where you and the people you care about can think together with AI in real time. No more screenshotting AI responses. No more copying and pasting between apps. Just one shared conversation where everyone contributes.
We believe the future of AI is not solitary. It is social. The best ideas emerge when diverse perspectives meet intelligent tools. That is why we are building TandemChat.
What we believe
Collaboration first
AI is powerful. AI with your people is transformative. Every feature we build starts with the question: how does this work for a group?
Privacy by design
Your conversations are yours. We encrypt everything end-to-end, never train on your data, and give you full control over what is shared.
Simplicity over complexity
Planning should feel effortless. We strip away everything that does not serve the goal of helping you think and decide together.
Speed of thought
Conversations move fast. Our AI responds instantly, our interface stays out of the way, and your plans take shape in real time.
The "team"
TandemChat is built and maintained by one person: a PM who loves travel and has an almost pathological need to plan things. Weekend getaway? He has a spreadsheet. Dinner with friends? He has a spreadsheet. Going to the grocery store? You get the idea.
For years, he was the designated Trip Planner in every friend group. And for years, his friends gave him endless shit about it. "You're sending another itinerary?" "Why is there a Google Doc for a beach day?" "Please stop adding agenda items to our group chat."
So he built TandemChat, a tool that lets him bring his friends into the planning process instead of just inflicting his plans on them. Now when they complain, he can say: "You were literally in the room when we decided this."
This is a side project, built with love and an unreasonable amount of caffeine. If you find a bug, he'll fix it as quickly as he can, which, depending on his day job, could be anywhere from "immediately" to "this weekend, probably." He appreciates your patience and your willingness to plan things with other humans.
Built with love (and OCD),
