COS

Conversational Operating System interface for cross-platform data orchestration.

What It Is

COS is an experiment in collapsing the app layer. Instead of switching between tools to move, query, and transform data, you converse with a single interface that orchestrates the underlying systems on your behalf — files, databases, calendars, and APIs treated as one addressable surface.

The research question is simple to state and hard to build: can a conversation-first interface beat a GUI for multi-system workflows? COS is our attempt to answer it with a typed, auditable command layer rather than a chatbot bolted onto existing apps.

Key Features

Unified Data Surface

layers

Every connected source is exposed through one typed schema. Ask across systems without writing integrations.

Auditable Commands

fact_check

Each conversational turn compiles to a deterministic, inspectable command plan before it executes. Nothing runs unseen.

Local-First Execution

shield

Sensitive operations resolve on-device where possible. The cloud is a fallback, not the default.

FAQ

When can I try COS? add

The beta program opens once multi-source orchestration stabilizes. Follow the build for progress notes — development is public in the journal.

Is COS a chatbot? add

No. Conversation is the input method, but every turn compiles to an inspectable command plan. You approve what runs, and the plan is the contract.
