Is it really free?
Yes — Google offers a generous free tier for casual use. You don’t need to enter a credit card to get started.
What if I use it a lot?
If you analyze large amounts of text regularly, you may eventually hit the free limit. In that case, Google will ask you to add a payment method to continue — you only pay for what you use beyond the free tier. Typical personal use costs just a few cents per month at most.
