Courses/Claude Code + Local AI/Assistant for freelancers
Lesson

Assistant for freelancers

A small local application that helps you with day-to-day paperwork as a freelancer: create invoices, keep track of income and expenses, and answer questions about your own documents. Everything on your computer, with no monthly fees.

  • Build a simple invoicing tool tailored to your needs.
  • Automate repetitive office tasks with local AI.
  • Keep your financial data private on your machine.

Key concepts

Step by step

Terminal
cd ~/proyectos-ia
mkdir asistente-autonomo
cd asistente-autonomo
claude

Run on your computer

Terminal
npm install
npm run dev

Create a test invoice and export it to PDF.

If something goes wrong

  • Incorrect totals — tell Claude Code the exact VAT/IRPF percentage for your situation; ask it to show the breakdown.
  • Lost data — that's why we insist on backups; restore the latest one.
  • The PDF looks bad — ask for a cleaner invoice design with your logo.

Practice challenge

Add reminders for unpaid invoices and a button to generate the quarterly summary ready to send to your accountant.
