For prosecutors and defenders, few evidence types are as time-consuming, or as revealing, as jail calls. They’re often full of key insights: admissions, witness details, or behavioral patterns that can make or break a case. But with hundreds of calls recorded in a single investigation, even the most dedicated teams struggle to review them all.
That challenge is exactly what Brief One is helping to solve.
The Challenge: Hundreds of Calls, Limited Time
At the Brazos County District Attorney’s Office, Jonathan Eisenrich, who manages digital forensics, described how the sheer volume of calls had become unmanageable.
An area we’re really using Brief One right now is actually with the jail calls. There are tons and tons of jail calls and it is impossible for us to go through them all. We had interns go through some, we’ve had prosecutors go through them just trying to make anything of note.
Each jail call on its own may seem manageable, but when hundreds accumulate in a single case, the workload becomes overwhelming.
It’s the volume. Most of the time they’re 10–15-minute jail calls, but there can be hundreds of them. So it’s just sheer volume that they can’t sit and listen to every single call, and there’s often a lot of good information.
For many offices, that meant dedicating countless hours of staff time, often forcing legal professionals to work nights and weekends just to meet their obligation to review every piece of evidence.
The Breakthrough: AI Summaries at Scale
With Brief One, Eisenrich’s team can now upload all jail calls directly into Axon Justice and receive concise AI-generated summaries of each recording.
With that summary that Brief One shows, you can actually just upload all of the jail calls straight to Axon and it’ll give you that AI summary. At a quick glance, we can tell what’s useful, what’s not. It took jail calls from taking days to a matter of hours. It has saved us an incredible amount of time.
The change was immediate and even morale-boosting.
One of our prosecutors even jokingly said it’s so nice now he’s gonna start doing jail calls again.
By turning long hours of playback into instant overviews, Brief One helps prosecutors quickly identify the calls worth deeper review while preserving full access to the original recordings for verification when needed.
Rebecca Gross, a Technical Litigation Analyst with the Shelby County District Attorney’s Office, has seen the same impact.
Definitely jail calls — it’s the area we use Brief One the most. It’s saved us an incredible amount of time.
Her team initially approached AI summaries with caution, but that skepticism didn’t last long.
We were hesitant first with worrying because transcripts aren’t a hundred percent accurate, but it’s amazing how accurate the summary is.
The Impact: From Missed Evidence to Meaningful Insight
Before Brief One, reviewing every jail call was an exhaustive, time-intensive process that often stretched limited resources to the limit. Now, prosecutors can triage dozens of calls in a single sitting, flag what matters, and focus on building stronger cases.
For Eisenrich and his team, that shift represents more than just time saved, it’s the ability to fully engage with their evidence again.
We’re glad we now have Brief One to go through and start utilizing jail calls fully again. It’s a huge gain for justice.
Transforming How Legal Professionals Work
What once took days now takes hours. What once depended on limited staff can now be managed by anyone with access to Brief One.
By combining AI-powered summarization with human expertise, prosecutors and defenders are reclaiming one of their most valuable resources, time, and applying it where it counts most: uncovering the truth.
Brief One doesn’t replace the human element of case review; it restores it.
