What it is

Control a personal AI assistant, called openagent, to automate work and create custom apps.

Real use case example

"A solo developer, Sarah, wants to create an Amazon price tracker for a new product. She creates a custom app with openagent, using its coding agent to pull Amazon data, store it in a Google Sheet, and send a Slack notification when prices change. She now tracks prices in real-time without manual updating."

When to use it
  • •When you need to automate repetitive coding tasks and focus on high-level development
  • •When you want to integrate AI assistance into your browser usage for tasks like research or data extraction
  • •When you require an AI-powered assistant for general computer use, such as file management or system monitoring
Ready-to-paste prompt
Visit the demo page at https://demo.openagentai.org and input a prompt like 'Write a simple Python program to print the Fibonacci sequence up to the 10th number' to see OpenAgent in action
Heads up: Ensure you have a compatible version of Go installed, as OpenAgent is built with Go and requires a specific runtime environment to function correctly
