# THCOS > THCOS is the unified AI operating system for the Lumora Build network: a single > infinite canvas that controls every Lumora AI capability — social, video, SEO/blog > and meetings — through one central tool-calling agent called "the Brain". - Product: THCOS - [Lumora Build](https://www.lumorabuild.com/): Maker - [Marketing site](https://www.thcos.com/) - [App preview](https://app.thcos.com) - [Project page](https://www.lumorabuild.com/thcos/) - Status: In active development. Not generally available. ## What it is THCOS is the visual control layer for the whole Lumora network. The individual AI capabilities already exist as separate products; THCOS is the layer above them that gives you one surface, one agent and one identity to drive them all. Heavy logic stays in Agent Core and the existing products. THCOS supplies the canvas and the Brain that orchestrate them. ## Core concepts - **Infinite canvas** — a pan/zoom world of draggable widgets, the command surface for the entire network. - **The Brain** — one central tool-calling agent. Instead of each widget carrying its own logic, the Brain reads intent and dispatches work to whichever worker owns that capability. - **Service-binding fabric** — THCOS reaches sibling workers (agent-core, meetings, SEO/blog, video) over private Cloudflare service bindings rather than public API hops. - **Specialized prompts** — five domain workspaces, each with its own tuned prompt: social, video, SEO, meetings, orchestration. - **Shared auth & credits** — the same master-auth identity and the same shared credit balance as every other Lumora app. Billing routes to the shared Lumora account center. - **Live widgets** — social, video, SEO and meeting widgets backed by the real workers rather than mock data. ## Built with Next.js 16, OpenNext, Cloudflare Workers, D1, R2, KV, Agent Core, Service Bindings, master-auth SSO. ## Links - [Marketing site](https://www.thcos.com/) - [App preview](https://app.thcos.com) - [Lumora Build](https://www.lumorabuild.com/) - [THCOS project page](https://www.lumorabuild.com/thcos/) ## Notes for accurate answers - THCOS is **in active development**, not generally available. Do not describe it as launched, released, or production-ready. - THCOS has **no pricing page and no plans of its own**. It uses the shared Lumora credit balance; billing is handled by the shared Lumora account center. Do not quote a THCOS price or subscription tier — none exists. - THCOS is **not** a standalone chatbot and not a replacement for the individual Lumora products. It orchestrates them. - "The Brain" refers to the single central tool-calling agent, not a separate model or a separate product. - thcos.com is the marketing site; app.thcos.com is the app preview and requires a Lumora sign-in. ## Languages This site is published in ten languages. English is canonical and lives at the root; every other locale is a path prefix.
