Evidence review software for criminal defense.

Alarion reads the whole file, phone extractions, call records, body cam and emails, and returns a case chronology, the contradictions in the state's theory, and every exculpatory lead, each one cited to its source.

The Solution

Four things you can take into the courtroom

A complete case chronology, every source on one timeline
The contradictions and gaps in the state's theory
Alibi and exculpatory leads, surfaced rather than searched for
A court-ready report, with the citation behind every line
Every point to prove, disprove or tackle, drawn from the file
Alarion Platform

A full evidence workbench: timelines, entity graphs, location views, contradiction flags and court-ready exports. Ask a question in plain English; every answer cites the underlying artifact.

The architects of the world's leading law-enforcement forensics stack, now solving the evidence crisis for the defense.
The unfair game

The prosecution has a forensic lab.
You have a deadline.

Around 90% of criminal cases now involve digital evidence (ScienceDirect, 2024), and the file only gets bigger.

Your side of the table
A lawyer. A laptop. Boxes of discovery.
You're expected to review the same terabytes by hand, on the clock, before trial.

The other side
Forensic labs. Dedicated analysts. Purpose-built tooling.
The state extracts, decodes and leverages every byte of digital evidence in your client's case.
Which leaves you two choices, and you already know both of them.
Read a quarter of the file
AND HOPE THE REST HOLDS NOTHING
Days of your time still cover a fraction of the evidence. The thing that helps your client is in the part nobody opened, and the state has read all of it.

BECAUSE THE FILE CANNOT BE READ IN TIME
Not because the case is weak, but because the deadline arrived before the discovery did. The file made the decision for you.
The unread file decides
Prosecution throws tons of data at us on purpose. It’s not possible to go over all of it.

How it works

Upload the discovery. Alarion reads all of it.

  1. Step 01

    Upload the discovery

    Phone extractions, call detail records, body cam and CCTV, emails, social media returns, PDFs and scans. The formats you actually get, including the messy ones.

    Step one: the case file list in Alarion, every uploaded item typed, dated and marked ready
  2. Step 02

    Alarion reads all of it

    Every message, record and frame, not a sample. Devices, accounts and locations are resolved into one picture of the case instead of a folder per source.

    Step two: locations from trackers, call records and warrant returns resolved onto one map
  3. Step 03

    You get the timeline, the contradictions and the leads

    A complete chronology, the gaps in the state's theory, and the evidence that helps your client. Ask a follow-up question in plain English and the answer arrives the same way.

    Step three: the analysed case timeline, with contradictions flagged and each entry linked to the file it came from

Every line in every output cites the source file it came from, so you can take it to the judge rather than take it on faith.

Or run it where you already work

Alarion plugins for Claude Cowork and Google NotebookLM bring the same evidence engine into the AI workspace your firm already uses. Same citations, same case isolation, no new workflow to learn.

Built for the standards of the courtroom

AI you can put in front of a judge

01

Every Insight Is Traceable

Every timeline entry, flag and answer links back to the source artifact (message, cell record, frame) so you can defend it on the record.

02

Augments Your Experts

Alarion does the triage and preparation; your forensic experts and investigators focus on the cases, and the questions, that need them most.

03

Your Cases Stay Yours

Case-isolated by design, with cloud or fully on-premises deployment for the most sensitive matters. Your data is never used to train shared models.

04

Built by Cellebrite's Forensics Leadership

The founders ran Cellebrite's Digital Forensics business unit, its investigative analytics and cloud teams, and its AI and SaaS platform. The same discipline about evidence handling, now working for the defense.

Handles the messiest real-world formats, and shows its work.
What it replaces

Three ways the file gets read today. None of them reads all of it.

Doing it yourself
DAYS PER CASE
Reads what a person can read before the deadline, which is a fraction of the file. Alarion reads the rest, and tells you which part of it matters.
Coverage < 25%
Retaining an outside expert
$5K TO $100K PER CASE
Invaluable on the stand, too slow and too costly to triage every case on your desk. Alarion does the triage so the expert is worth retaining when you do.
Reserved for the few
A general-purpose AI assistant
NO CHAIN OF CUSTODY
It does not read a phone extraction, it cannot show which file an answer came from, and an invented citation is a bar complaint rather than an inconvenience.
Nothing you can cite
Harvey does not surface insights. I love the way you’ve built your solution.

  • Evidence gaps found too late
With Alarion
  • Full evidence map in hours, not weeks
  • Contradictions & exculpatory leads surfaced
  • Walk into trial knowing what's in the file

What a design partner found

I have seen what Alarion can do to make an impossible amount of discovery possible.
Steven H.
Criminal Defense Attorney · Design Partner
Read the full design partner story

“Discovery in criminal cases used to be measured in pages. Now it is measured in gigabytes or even terabytes — body-worn camera video, surveillance video, phone extractions, social media, wiretap recordings, financial records and more. I have seen what Alarion can do to make an impossible amount of discovery possible. In one example, a search for a gun across hours of video surfaced images I needed to know about. Alarion also found specific sentences inside an hour-long interrogation. If you do not have hundreds or possibly thousands of hours to review discovery the old-fashioned way, you need Alarion.”

“Justice deserves
a fair fight.”

Bring us one matter. We will show you what reading the whole file looks like, on your own discovery, before you decide anything.
