## Overview

Nelly is built around the idea that a small team of specialised agents beats one general assistant. Inside Nelly Studio you describe what an agent should do using headings, lists and plain sentences - no code and no special syntax. You attach toolkits such as a browser or a database so agents can actually act, then test and refine their behaviour conversationally until they match your intent. Complex goals can be broken down into tasks delegated to sub-agents, effectively building a coordinated team.

Nelly Chat is where those agents go to work. You hold natural, contextual conversations with them in organised threads, group agents into departments with drag-and-drop, and inspect an activity view that shows which tools were used, browser screenshots and each step of progress. On the technical side, agents and their data run locally on your machine while the reasoning model runs in the cloud; Nelly says it transmits only conversation history and context to the LLM provider and does not store it.

Paid subscribers can connect their own model providers, including Anthropic, OpenAI, OpenRouter and LM Studio, for more control and privacy. Nelly currently uses Anthropic's Claude Sonnet 4 as its default model, supports Windows, macOS and Linux, and has an MCP server integration and a marketplace for sharing and monetising agents marked as coming soon.

## Key Features & Capabilities

- **Studio natural-language agent builder:** Create custom agents by describing their job in plain language with headings and lists; no coding or special syntax required.
- **Toolkits and sub-agents:** Give agents browser and database tools, and split complex work into specialised sub-agents to form a coordinated team.
- **Nelly Chat with threads and departments:** Hold natural conversations in organised threads, group agents into departments by drag-and-drop, and review detailed activity logs with browser screenshots.
- **Local-first data with cloud LLMs:** Agents and their data stay on your computer while only conversation context is sent to the model provider and not stored by Nelly.
- **Bring your own model provider:** Paid plans connect Anthropic, OpenAI, OpenRouter and LM Studio models for extra control and privacy, with MCP server support coming soon.

## Primary Use Cases

- **Automate repetitive knowledge work (Operations or admin professional):** Build agents that browse the web or query a database to gather, compare and summarise information you would otherwise handle manually.

- **Keep data on your own machine (Privacy-conscious user):** Run agents locally and, on a paid plan, connect your own LLM provider so sensitive context stays under your control.
- **Organise a virtual agent department (Team lead):** Group specialised agents into departments, delegate tasks to sub-agents and monitor progress from the activity view.
