Hi, my name is Timothy and I've been working on Nelly for the last few months.
Nelly is an AI agent/assistent platform where you can build, use and soon share AI agents. You create the agents by simply writing instructions in natural language, and you can break down these instructions into smaller parts as sub-agents. You then use these agents with Nelly's chat interface to perform tasks for you.
Nelly is a desktop app, currently for Mac but soon also for Windows and Linux, that you install on your computer. The agents and their data are stored on your computer but the LLM used for decision making, etc. is running in the cloud (currently Claude 3.7 Sonnet via OpenRouter). With a paid subscription you can connect Nelly directly to your own LLM providers.
You will soon be able to both share and explore third-party tools and agents on the Marketplace. Built-in tools at the moment include a browser, a calculator, and a database.
Read about how I use Nelly to pay out my salary, from calculating the net salary, making the bank transfers, and declaring it to the tax authorities, to recording it in my accounting software:

This is just the beginning, the next step is to add MCP support, then launch the Marketplace with both agents and tools, and improving the platform with file support and more.
I'm looking forward to see what you build!
Installed Nelly last night and spent half an hour just roaming around the interface; even at first glance, the no-code builder feels intuitive—slotting in sub-agents and toolkits is nearly drag-and-drop.
One idea that could speed up onboarding: a public gallery of ready-made agents (think SEO audits, inbox triage, churn-risk pingers). Starting from a template would slash time-to-value and jump-start your upcoming marketplace.
Minor blocker for me: I split my day between Mac and Windows. Any ETA on Windows support or a browser-based option? Once that’s live, I can roll Nelly out across my whole team. 😬
In the meantime, great work! 🙏
I just tried building a simple agent to fill out a form using the provided data, and it worked really well- 3 out of 4 forms were submitted successfully, so there’s still a bit to improve, but overall it’s promising. Earlier today, I accomplished the same task using Automatio.io, but the key difference was setup time: Automatio took me about 10 minutes (and I had to click a lot!), while Nelly handled it in just 1 minute. I’m definitely planning to push it further with more complex scenarios. Combining NLP and RPA really feels like the future of automation
Hi Timothy,
I’m Nima, founder of Bestofweb .site where we spotlight standout digital tools and the people building them. Congrats on launching Nelly — love how you're combining natural language agent creation with local data and a clean desktop setup. The sub-agent structure and built-in tools make it feel both powerful and approachable. We're cheering on your launch and would love for you to explore our directory.
@Firecrawl is trying to hire AI agents (and the even have Slack with AI agents) :D maybe something for collab?
This is super cool! Love how Nelly makes knowledge sharing within teams so much faster and smoother. Definitely something modern workplaces could use. Great job!
