What Serjeant AI does differently
Every answer checked. Every time.
"The question isn't whether your opponents are using AI. It's whether they're verifying it."
Verification Architecture
Four shields.
Zero blind spots.
Independent verification layers that audit every claim before it reaches your brief.
Source-Backed
Every claim traced to its source document.
If it’s not cited, it’s not in your answer.
Jurisdiction-Verified
Checked against federal, state, and circuit hierarchy.
The right precedent from the right court.
Time-Current
Freshness thresholds tuned per practice area.
Stale law flagged before it reaches your brief.
Consistency-Matched
Semantic cosine similarity between claims and sources.
Catches contradictions before you file.
Four independent checks. Trust earned, not assumed.
How It Works
Ask. We verify.
Three steps. Every answer checked before you see it.
Ask
Type any legal question in natural language.
