What it is

Use senpi to create a customized command-line agent that integrates various tools and services for automating tasks.

Real use case example

"A founder, Alex, wants to automate their Stripe payment notifications. Alex sets up senpi in 45 minutes, connects their Stripe and Google Spreadsheet accounts, and configures a task to send a thank-you email using Mailgun whenever a new customer signs up. The result is a seamless notification system that saves Alex several hours of manual work each week."

When to use it
  • When you need a customizable AI agent for your startup's specific requirements
  • As a replacement for a basic AI tool, such as pi-mono, with added features and extensions
  • For building a CLI-based AI-powered application with TypeScript
Ready-to-paste prompt
Create a new file `extensions/myExtension.ts` with a custom extension class, then run `npm run build && npm run start` to load the extension into the senpi agent
Heads up: Senpi requires a compatible version of Node.js and TypeScript to be installed on your system, specifically Node.js 16 or higher and TypeScript 4 or higher, to compile and run the code without errors
