# About About # Professional legal research, open to everyone it serves. Antecedint turns the public legal record into research anyone can search for free from their AI assistant. It is measured against decisions professionals already made, and it gets better as the people who use it report what is wrong. Patents and prior art are searchable today. Case law is being built the same way, and tax is next. Platforms that want it inside their own products build on the API, and that is what keeps search free. ## How it works ### From the public record Patents, Board decisions, court opinions and agency filings, taken from public sources and parsed to the parts a question turns on. ### Measured in the open Every area is tested against decisions professionals already made: examiner citations, Board decisions, how courts treat earlier cases. The numbers are published with their labels. ### Corrected by the people who use it Searching is free from your AI assistant. When you or your agent find a wrong record, report it: once it is checked, the fix reaches everyone and the report earns credits. ## We are hiring for legal analysis and data science. People who read the law closely, and people who measure retrieval honestly. Send a résumé and a note about the work you would want to do.
