You focus on the facts. Arc does the rest. The modern case workspace where you work the file — not just store it. A 400-page production arrives as the affidavits, reports and logs inside it. Six hours of body-cam arrives transcribed and timestamped. Every fact you find keeps its source, and every answer Arc gives is cited to the passage. Built by a prosecutor for prosecutors, public defenders, and investigators working fact-intensive cases.

Stop watching
Every recording is transcribed and timestamped in the background as it uploads. Search six hours of body-cam for one word, click the line, and the player is already there. Mark the stretch, bleep or blur it, ship a clean copy.
03
Stop searching
Every fact you find keeps its source. Clip the admission once and it carries the document and page into the brief, the hearing and the appeal. Every answer Arc gives is cited to the passage.
Every result is a link to the exact spot — the page, the sentence, or the second of video. Paste it to co-counsel and they land on the same line. The link survives reorganizing your folders and never expires; only people on the case can open it.
The production is split for you.
Upload everything that was produced — police reports, body-cam, dash-cam, interview audio, lab results, witness statements, phone extractions. Arc reads each file, finds the documents inside the long ones, writes a summary of every one, and files it in a folder plan it proposes. Files or Documents — your call — and every filter, count and bulk action follows the side you're on.
The same evidence, in whichever view the next decision needs.
Inventory
Know what it is before you open it.
Title, type, people named and an Arc-written summary for every document, whatever the file type. Filter by type, folder, status, date or source file; save any slice as a tab with a live count.
See it in the tour →Folders
Folders that keep themselves filed.
Pick an arrangement — by document role, by party or witness, by timeline phase — and see the plan before anything moves. A folder that holds K-9 reports keeps taking K-9 reports, including ones found inside tomorrow's upload.
See it in the tour →Viewer
Trust what's on screen, whatever the format.
The original beside what ChargeStack read from it — PDFs, images, Office files, audio and video in one viewer. Transcripts scroll with playback; a citation opens on the cited page or second.
See it in the tour →Chronology
In order, with nothing you didn't approve.
Every dated event the case contains, with corroboration counts. Build with Arc and suggested entries stay dashed until you accept them. Export to Word, PDF or CSV, every entry cited.
See it in the tour →Witnesses
The who's-who, already built.
One card per person, ranked by who matters, with one evidence trail cited back to every document that names them. "Garcia," "Det. Garcia" and "the reporting officer" become one card; the borderline calls come to you.
See it in the tour →Redact & export
Get it out the door.
Blur, black out, mute or bleep on the waveform; a separate redacted copy renders and the original is never touched. Export a document, a folder or the whole case as a browsable package that works offline.
See it in the tour →Own comparative sentencing.
Every Montana Department of Corrections sentencing record and every sentence reported in a Montana Supreme Court opinion, combined into one list — one row per sentence, nothing double-counted, nothing dropped. Nothing else in Montana puts both sources in one query.
Ask
"What is the typical term for felony theft in Missoula County?" "How has this judge sentenced this offense before?" Arc answers in plain words — the count, the typical term, where half the sentences fall, where nine in ten fall — with the records in a card and an Open in Browse link to check or extend the result yourself.
Browse
A filter-first finder over the whole dataset: statute, county, judge, year, term, age at sentencing, weapon, persistent-felony-offender status, appeal outcome. Pick one and the others narrow to what's left, with counts. Click any row for the whole docket; export the filtered set to CSV.
Case facts
Word-search the facts the Supreme Court recites — vehicle AND (alcohol OR intoxicat*) — to find comparable appealed cases to read, with the sentencing court's findings, the issues decided and paragraph cites into the Court's own text.
Careful by design. Every figure comes from the records, never from Arc's own arithmetic; fewer than twenty sentences and you get the count, the shortest and the longest instead of a misleading "typical." Earlier versions of a DOC record stay readable when it changes. The same dataset answers sentencing questions inside any case's Arc chat. Historical public-record data for research and context — not a prediction, not legal advice. Enabled per organization. See it in the tour →
Inside a Google Cloud boundary built for criminal-justice data.
ChargeStack runs inside Google Cloud Assured Workloads with the CJIS control package. Google enforces the package as policy on everything inside the boundary — and on top of it, three guarantees are enforced in the runtime, not by a policy document.
US-only residency
Database, files, backups, logs, keys and the AI models that read your documents all live in US regions. Policy blocks anything else from being created.
Your keys, every service
Storage, database, backups, secrets, logs and queues are encrypted under customer-managed keys inside the boundary, with a per-organization key wrapping your content on top.
Restricted services
Only services Google covers under its CJIS package can run inside the folder. Third-party AI vendors cannot be switched on for a criminal-justice organization.
Identity inside too
Accounts are hosted on Google Cloud Identity with two-step verification enforced by policy: a passkey or an authenticator app, never a text message.
01
Runtime gate
Our ops staff literally cannot read your case content. A gate in the data-access layer refuses every ops query that touches content — it is a technical control, not a code-review checklist.
02
You hold the key
If support needs a deeper look, they request it. You approve from your admin panel — single case, time-boxed, revocable instantly. If you don't open the door, no one walks through it.
03
Receipts, every time
Every ops query against your organization writes a row visible to you. "Zero access today" is a real signal, not a marketing line.
