Nelly is a desktop platform for building, using, and sharing AI agents. It is made by Pine Enterprises AB and describes itself as a complete AI agent platform covering the full cycle: building agents in Studio, working with them in Chat, and, once it launches, sharing them on a Marketplace. The site says no coding is required, and agents can handle anything from simple tasks to complex workflows.
The company's stated direction is that software will increasingly be AI itself rather than something AI writes. Nelly is presented as a first step: agents work alongside existing software to automate routine tasks, with a longer-term goal of autonomous teams that need only strategic direction. The product is currently in beta, and the pricing page notes that limits and features may change when it exits beta.
Agents are created in Nelly Studio by writing instructions in natural language. Users describe what the agent should do and can format the instructions with headings, lists, and other content types. Agents can be given toolkits, such as a browser and a database, and can be tested in plain language and refined until their behavior matches what the user intended.
Nelly's FAQ explains the architecture. Agents and their tools run locally on the user's computer, and agent data is stored locally, while the language model that powers them runs in the cloud. Only conversation history and context are sent to the LLM provider, and Nelly says it does not store that data. The site states it currently uses Anthropic's Claude Sonnet 4 and may change providers.
In Studio, sub-agents let users split a complex task into smaller problems and hand each to a specialized agent, which is how a team of agents is assembled. In Chat, conversations are organized into threads, which the site says also improves performance, and agents can be grouped into departments using drag and drop. Chat is described as natural, with no special commands or syntax to learn.
An Activity view shows what agents are doing in detail: which tools they use, browser screenshots, and step-by-step progress. Agents operate at human-like speeds and use one browser at a time, which the company says supports compliance with website terms of service. Paid plans can connect custom LLM providers, and support for user-supplied MCP servers is listed as coming soon.
Nelly is an AI agent platform from Pine Enterprises AB for building, testing, using, and sharing AI agents. Agents are created in natural language with no coding required, and they run locally on the user's computer.
Nelly has a Free plan at $0 per month, Pro at $9 per month, and Pro+ at $20 per month. The plans differ mainly in message limits: 30, 100, and 250 messages per 30 days. Custom enterprise plans are available through sales.
Yes. The Free plan costs $0 per month, needs no credit card, and allows unlimited AI agents with up to 30 messages per 30 days. The site notes that limits and features may change when Nelly exits beta.
Agents and their tools run locally on the user's computer, and agent data is stored locally. The LLM that powers them runs in the cloud, and only conversation history and context are sent to the LLM provider. Nelly states it does not store that data.
Nelly currently uses Anthropic's Claude Sonnet 4 and may change providers based on performance and cost. With a paid plan, users can connect models from OpenAI, Anthropic, OpenRouter, and LM Studio.
Every user-to-agent and agent-to-subagent message counts. If you message an agent and it consults a sub-agent, that is two messages. Limits use a rolling 30-day window from the first message, and unused messages do not roll over.
The sources list LLM providers (Anthropic, OpenAI, OpenRouter, LM Studio) and built-in tools such as a browser and a database. Connecting custom MCP servers is coming soon. No business-app integrations are named.
No. Nelly does not offer refunds for subscription payments. Users can cancel at any time, and the subscription stays active until the end of the current billing period.
