A thinking partner for the everyday. Not a demo, not a toy. We made Casimir to be the one you reach for — capable enough to keep up, generous enough to live with, quiet enough to think alongside.
Casimir 26A is our first model. It isn't the biggest one out there. It doesn't need to be. We wanted one that thinks clearly through the work most people actually do — the email, the draft, the question, the half-formed idea — and keeps up without wandering off.
Some things shouldn't mix. Vaults make sure they don't — each project sealed off from the rest. Folders keep the conversations inside in order. It works the way you do.
The longer you use it, the better it knows you. Casimir picks up what matters from your conversations and holds onto it. So you don't start from scratch every morning.
Plenty of room to use it the way you want. We didn't want a tool people had to ration. We wanted one they could lean on every day, for whatever came up. So that's how we priced it.
A limited experience, on the house. Something to try Casimir out, nothing hidden behind a wall. Use it once to decide, if it earns a place in your day.
Generous limits, every tool unlocked, memory that holds onto what matters. For the kind of work that doesn't fit in a free tier.
Extended memory, maximum context, and an agent that works alongside you. For when conversation isn't enough.
Open to everyone
