IACompara

You upload an electricity bill as a PDF or image, or type in your figures by hand, and IACompara returns a personalized savings estimate for your home in Spain.

The AI energy comparator reads your actual kWh usage and contracted power, then looks for cheaper electricity and gas rates than the ones you pay now.

The cost calculation includes taxes such as IVA and the electricity tax, so the figure you see is closer to what a real bill looks like than a headline price per kWh.

IACompara also helps you move to a better provider once you find one.

The site says savings can reach up to 400 a year, though what you save depends on your own consumption and current contract.

Automatic extraction from a bill saves typing, and manual entry works if you do not have the document on hand.

The service is meant for Spanish energy customers, so it is not useful elsewhere.
