Capabilities

What your agent will actually do.

Not another chatbot. A real operator that executes across your tools — every action visible before it runs, costs transparent upfront, and memory that builds with every task it handles.

01 · On the record
Every action, visible.
Nothing moves silently. Every tool call, vault access, and decision is logged before and after execution — append-only, exportable, compliance-grade.
02 · Visible before it runs
You see it. You decide.
Before anything executes, you see exactly what Cosius is about to do. Set rules per tool, per amount, per workflow. Approve, edit, or stop it — on your terms.
03 · Autonomous
Runs without you there.
Scheduled and triggered workflows. Wakes up on Mondays. Fires on webhooks. Handles your inbox overnight. You wake to a briefing, not a backlog.
04 · Remembers
Context that compounds.
Your tone. Your people. Your priorities. Cosius builds persistent memory across sessions — so it gets sharper with every task it handles, and never asks twice.
05 · Infinite extensions
Any tool. Any workflow.
Gmail, Stripe, Calendar, Drive, Slack, Notion, Docusign, HubSpot, Salesforce, QuickBooks, Linear — and a marketplace of thousands more skills built by Cosius and the community.
06 · Built on Anthropic
Reliable. Explainable.
Powered by Anthropic's latest models and infrastructure — so execution is dependable, reasoning is followable step by step, and you're always on the most capable model available.
We're not selling a chatbot

Cosius isn't a chatbot. It's an AI Employee.

Three different tools, three different jobs. Chatbots answer questions. Team members lead and decide. Cosius executes the operational work in between — across your tools, with memory, with a paper trail. Here's where each one fits.

A day in the life

Tuesday, 09:14 AM.

You run a 14-person agency. Coffee in hand, you open your laptop. Three things happened while you were away. None of them needed you — except the one that did.

“Good morning. Here is what happened while you were away. Three decisions need you — none urgent, but Acme is waiting.”
That's the daily brief. You approve two decisions, redirect one, and the agent resumes — finishing each thread while you take your first meeting. By noon, the inbox is handled. By five, the week is moved.
That's roughly 9 hours of operational work, handled before lunch.

“The right way to think about this isn't automation. It's informed delegation— every action visible before it executes, costs transparent upfront, and an operator that learns your context over time.”
