The thesis:
Great agents need
more than intelligence.

They need context, a way to act, and memory that carries experience forward.

Cetus begins with a simple belief. As intelligence becomes more capable, the environment around it matters more. The desktop is where our intentions, conversations, and unfinished work already meet.

One person.
Several kinds of intelligence.

We build for people who use several agents together. Codex for one task, Claude Code for another, a different runtime for a second opinion. Each brings its own strengths, tools, and ways of working.

A personal assistant should leave that choice open. Choose the runtime for the task while keeping the surrounding work — projects, schedules, and results to review — in one place.

Your accounts.
Your tokens. Your choice.

You already have a relationship with your model providers: API keys, CLI logins, preferred models, and a token budget you decide how to spend. That should be the starting point.

Cetus is designed around using those existing accounts and runtimes. Intelligence stays with the provider you choose; the assistant layer makes it useful across your desktop.

An agent is a loop.
Give it a world to work in.

Context gives intelligence something meaningful to reason about. Tools turn that reasoning into action. Reflection brings the outcome back into the next decision. Over time, useful experience should accumulate.

Quick Launcher makes this loop reachable. The distance between having an intention and involving your agent should be a gesture, wherever you happen to be working.

Context

The environment becomes available to the agent through your voice, meeting transcripts, selected text, and opt-in screen memory. You decide what enters the conversation.

Reasoning

Each provider’s runtime brings its own intelligence, models, and tools. Cetus gives that runtime a place in your day and leaves its capabilities intact.

Action

Runtime tools do the work. Automations give it a schedule. Conversations and the board make progress, results, and requests for your judgment visible.

Reflection

Memory carries decisions forward. Dreaming consolidates experience into durable notes. Proposed Skills offer recurring workflows for you to review and enable.

The models will change.
Your context should compound.

Your goals give the loop direction. Your feedback becomes part of what it knows next.

Your agent, right where you are.
