A marketplace of AI skills that actually run: 593 skills ship inside the Nexus Runner desktop app, reading your files, processing them, and producing charts and conclusions on your own machine. It executes, it doesn't just chat.

How is this different from Zapier or just asking a large model?

Zapier connects cloud apps through APIs; we work on the files on your machine. A model hands you prose; we hand you a table, a chart and a conclusion you can check. A skill is a program with an input contract, not a prompt.

No. Skills execute on your computer, source files never leave it, and output is written straight to your folder. Content is sent to the built-in model only when you use AI chat or a skill that needs a model.

What do I need to install?

Just Nexus Runner — the runtime ships with the app. No Python setup, no code.

How much is the free tier?

200 Nex per month on signup, reset at the start of each month, with every skill available and no tier gates. The four Runner tutorial skills are not billed.

How many runs does Pro at CNY 49 cover?

3,000 Nex per month. Skills bill per run and most cost 3-10 Nex, which works out to several hundred runs. Each skill's exact price is on its detail page.

Which Windows versions are supported?

64-bit Windows 10 and Windows 11. Windows is the only desktop client we ship.

How do I connect it to Claude Desktop or Cursor?

Nexus Runner speaks MCP: register it as an MCP server in your client and the skills show up as tools. The docs page walks through the setup step by step.

Where do skills come from? Can I build my own?

Skills are maintained by the platform and its creators, each with an input contract and sample data. You can also build your own in the Runner workbench — those stay yours, never published or encrypted.

Do you offer refunds?

Subscriptions can be refunded under our refund policy; the conditions and process are on the refund policy page. Nex already consumed is not refundable.
