Is this service really free?

Yes! Invobi is completely free to use. You only pay for the AI API calls directly to your chosen provider (like Google Gemini).

There are no hidden fees or subscriptions on our end.

Are there any usage limits?

The core service is completely free and always will be — no account registration required. Just bring your own API key and start generating invoices.

To ensure fair usage for everyone, you can generate up to 5 invoices per 24 hours. This is a rolling limit based on when you generated your invoices.

In the future, we plan to offer optional paid plans with unlimited invoice generations, the ability to save your invoices, edit existing invoices, iterate on generated invoices, create new invoices from existing ones, and schedule automatic invoice generation.

Is my data secure?

Your privacy and security are our top priority:

  • API keys are never stored — your key is only used for the single request to generate your invoice and is immediately discarded.
  • Invoices are never stored — your invoice is generated on-the-fly and sent directly to you. We don't keep copies of your invoices on our servers.
  • No data retention — all processing happens in real-time. Once your PDF is delivered, no trace of your data remains.

We believe in privacy by design — we simply don't collect what we don't need.

How is my API key remembered?

When you check "Remember API key", your API key is stored in your browser's localStorage — a secure, local storage area that only this website can access.

Important points:

  • We never store your API key — it stays entirely in your browser, on your device.
  • We never send it to our servers — except when making the API call to generate your invoice, where it's used once and immediately discarded.
  • You're in control — uncheck the box anytime to remove it from your browser.

This is the same technology used by countless websites to remember your preferences. Your API key never leaves your device unless you explicitly generate an invoice.

How do I get an API key?

Currently we support Gemini 2.5 Flash, with more AI models coming soon.

To get a Gemini API key:

  1. Visit Google AI Studio
  2. Sign in with your Google account
  3. Click "Create API Key"
  4. Copy the key and paste it above

Google offers a generous free tier, so you can generate many invoices at no cost.
