The idea for Takt.chat came from a fight.
The developer and his girlfriend both used a shared Claude account - separately, without telling each other - to vent about the same argument. The conversation merged. She noticed the chat, joined it, and Claude started receiving two contradictory accounts of the same conflict from what looked like a single user. At some point, the chat had been renamed "Why Michael is an inconsiderate asshole."
That incident exposed something real about shared AI accounts: most AI chat apps have no concept of multiple users in a session. Context from one person's conversation stays visible and active for whoever opens the same chat next. For households and small teams sharing a single subscription, there's no built-in separation between users.
Takt.chat's response is a multi-session-aware AI assistant that tracks who is present in a conversation and clears or segments context when participants change - hence the "forgets things when people leave the room" framing. The AI treats presence as meaningful rather than maintaining a single continuous thread across whoever happens to be using the interface.
It's a narrow use case, but a real gap. Shared subscriptions are how plenty of households and small teams actually use Claude, ChatGPT, and similar tools. The privacy issue is obvious in retrospect - anything you tell an AI in a shared session is sitting there for the next person who opens that chat. Takt.chat addresses this at the session layer rather than requiring each person to manage separate accounts. The app is live at takt.chat.
