Free AI is the most expensive AI

You are not paying with money, so you are paying with something else. A back-of-the-envelope on what a year of your prompts is worth.

The oldest business model on the internet

When the product is free, the transaction has not disappeared — it has moved. You are paying with the most valuable dataset that has ever existed about you: your questions, in your own words, in real time.

A rough valuation of you

  • A heavy user sends thousands of prompts a year — a live feed of intent, worth far more per record than browsing history.
  • Ad platforms price verified high-intent signals at dollars, not cents, per user per month.
  • A year of your prompt stream, packaged as a profile, is plausibly worth hundreds of dollars — recurring, forever.

Paying with money instead

The alternative is unfashionably simple: pay for software, own the result. A one-time licence for a local-first tool costs less than what your data quietly earns for someone else in a year — and the asset it builds (your indexed, searchable knowledge) belongs to you.

Free is a price. Make sure you know which currency it is charged in.

Keep your documents — and your questions — yours.
