Prove what your AI did. The whole turn, sealed and checkable.
An assessor, an examiner, or opposing counsel will eventually ask what your AI was asked and what it did with your regulated data. For most organizations that question has no answer, because nothing was keeping one.
What you hand over, and what it settles.
The answer was being written the whole time. Every captured interaction seals into a record on your own servers, under your own key. When the question arrives, you export the span they ask for. They test it for tampering themselves. The conversation moves from what you believe happened to what the evidence shows.

What an AI audit trail settles
Six questions come up in every review. Here's how the record answers each one before anyone has to scramble.
Each entry is signed on the device it came from, so usage traces to a person, a tool, and a time.
Entries chain together, and an edit or a deletion anywhere breaks the chain right where the person checking can see it.
Retention runs on the clock you set, a year of CJIS audit logs or HIPAA's six-year documentation window, so the span they ask for still exists.
The record is encrypted under keys only you hold, on servers you run. There's no vendor copy to breach or subpoena.
A sealed export of the span they name, plus the means to check it's intact without being shown your content.
It's built as evidence rather than as logs: ordered, signed, and checkable by the very person doubting it.
Everyone keeps logs. Evidence is rarer.
Most of the market treats the audit question as a search problem: collect what every tool emits, store it somewhere, and hope it adds up when someone asks. You end up holding a pile, not an answer. Verillian was built the other way around, starting from the day the record gets challenged.
That's the bar an assessor actually holds you to: not what you can piece together, but what you can hand over and have tested.
When the question comes,
answer with evidence.
Bring your framework's retention clock and your toughest reviewer. A pilot in your own environment is available, and the sealed records are yours to keep either way.
