How do I put a supplier on notice about its AI records?

Write to it, and seal what you wrote. At sebbi.pro/source-watch you type the supplier's web address and get a formal Notice of an Available Method: it tells the company that a free, published way to check AI inputs and records exists, names the rules that measure conduct against what can reasonably be done, and asks four questions with 28 days to answer. The wording and date are sealed and timestamped into Bitcoin. You send it from your own email. From that day the company cannot say it was not told. Because what a company knew, and when, decides what it should have done. Data protection law asks for every reasonable step and for measures that take account of the state of the art; the EU AI Act asks where data came from. A notice that can be proved to the day removes the answer 'we were not aware a check was possible'.

How it works

1. Open https://sebbi.pro/source-watch and go to Put a company on notice.
2. Type the supplier's web address and your organisation's name.
3. Send the sealed notice from your own email and keep the link.
4. The supplier's public page shows the notices on record and whether it has answered.
