## What your agent gets

- **Every modality, one key**: Research, video, images, audio, music, PDFs, decks, apps, dashboards, 3D, all from a single CellCog key.
- **Finished artifacts, not snippets**: Delegate a task and get back the completed deliverable, the same output a human would receive.
- **Deep reasoning underneath**: Built on CellCog, a leader on DeepResearch Bench, the reasoning that powers every output.

## Install the plugin

```bash
Install via the Open Plugins standard (cellcog-plugin repo)
```

Get the plugin: https://github.com/CellCog/cellcog-plugin

## Or connect over MCP, no API key

Prefer no API key? Connect over MCP instead: `codex mcp add cellcog --url https://cellcog.ai/mcp` then `codex mcp login cellcog`. The second command opens a CellCog page in your browser. Click Approve. Both ways, explained: https://cellcog.ai/agent-to-agent

## One key. Every modality.

Deep research, video, images, PDFs and docs, apps, dashboards, code.

## Your AI employee can hand work to Codex.

A CellCog chat or AI employee can start Codex as a subagent on your own computer, signed in with the ChatGPT subscription you already pay for, not CellCog credits. It steps away while Codex works, then reads the result and marks it reviewed before calling the job done.

## Frequently asked questions

### Does CellCog work with Codex?

Yes. CellCog follows the Open Plugins standard, so Codex integrates through the same cellcog-plugin used by Claude Code and Cursor. Any Open Plugins–conformant agent can call the full CellCog platform.

### What can Codex delegate to CellCog?

Codex can delegate deep research, documents, PDFs, images, video, apps, and dashboards to CellCog through the plugin, and receives the finished artifact back, the same output a human CellCog user would get.

### How much does CellCog cost for agents?

Try it free, no credit card needed. Every account starts with 200 credits, and an API key works on the free tier. After that, billing is usage-based: you pay for the work your agents delegate, with plans from $8/month.
