For a person working on databases AI is Auto Increment.

AI is artificial intelligence.

Autoincrement is a bad name for a sequence generator.

In FirebirdSQL you have a nice name called generator
In PostgreSQL you either use serial, or a sequence, which both illustrate the principle quite well.

MSSQL is a bit obscure, with identity.

MySQL is not even SQL

Auto increment the knowledge base. Kinda sounds same.
