AgentOp demo: build a private AI agent and ship it as one HTML file

A 62-second walkthrough of AgentOp: describe an agent and have AI draft it, add Python tools, run a real open language model entirely inside the browser with no install and no server, switch between on-device and cloud models, and export the finished agent as a single standalone HTML file that runs offline.

What happens, and when

• 0:00 Intro What AgentOp is: a private AI agent you ship as one file.
• 0:05 Generate an agent with AI Describe the agent you want; your own OpenAI or Anthropic key calls the model from the browser and a draft template opens in the editor.
• 0:14 Write Python tools Add Python functions to the agent; AgentOp extracts the tool schema the model calls them with.
• 0:22 Run it locally A Private Spending Auditor agent running entirely on-device: the open model downloads into the browser, then answers questions about a statement that never leaves the tab.
• 0:48 Local or cloud The same agent switched between an on-device open model and a cloud provider called with your own key.
• 0:55 Ship it as one file Export the finished agent as a single standalone HTML file that runs offline, from disk, with nothing to install.

Try the thing in the video

Everything shown above runs in an ordinary browser tab — there is nothing to install and no account needed to watch an agent work. If you want to know whether the on-device models will run on the machine you are reading this on, the browser check answers that in about a second, before anything downloads.
