A short tour

Inside Arc

Five screens from a sample case. What it looks like when discovery shows up, what Arc does with it, and how the lawyer asks it questions.

01 · Ingest

Drag in the box. Walk away.

Arc accepts whatever shape discovery shows up in — PDFs, transcripts, body-cam video, dash-cam audio, photo evidence. Every page is OCR'd, every audio file transcribed, every video characterized. Cost and progress are visible in real time, not at the end of an invoice cycle.

ChargeStack Arc — case dashboard showing ingestion progress, document totals, and live case cost.

02 · Inventory

Every document, sorted by what it actually is.

Arc classifies each file, extracts the entities it mentions, and slots it into a workspace structured for how lawyers actually work a case. Open a folder and find every document featuring that person, that location, that piece of evidence.

ChargeStack Arc — Document Inventory: entity-organized folder tree with document detail, live classification, and deep-search controls.

03 · Reorganize

One case. Many ways to look at it.

The same file might matter as evidence today and as a witness statement tomorrow. Ask Arc to regroup the case by document role, by party or witness, by timeline phase, or by source — and it proposes a folder structure with coverage stats before you commit to the change.

ChargeStack Arc — Reorganize with Arc: scheme picker offering grouping by document role, party/witness, timeline phase, or source/custodian, each with a coverage score.

04 · Characterize

Every file, read and described.

Video, audio, image, or PDF — Arc explains what's in it. For video, it surfaces representative keyframes and writes a plain-English description of the scene. For audio, a full transcript with speaker turns. For PDFs, an OCR'd, searchable copy with a structured summary. All citable.

ChargeStack Arc — document detail view: video file with keyframe preview strip, transcript, and visual-timeline summary.

05 · Open & Search

Open any document. Search inside it.

Click any file and read it where it lives — no download, no external viewer. Find the serial number on an evidence audit trail, the badge number on a body-cam log, the exhibit reference buried on page 47. Arc carries the search bar into every page it OCR'd.

06 · Redact

Redact what can't go out — and know it's really gone.

Open an audio or video file and mark what has to come out — drag on the waveform to mute or bleep a phrase, or pause on the frame and draw a box to blur or black out a face, a screen, an SSN. Arc renders a separate, production-ready copy with the content genuinely removed — audio truly silenced, video truly black — and re-checks its own output, so a redaction can never quietly fail. Your original file is never touched.

ChargeStack Arc — Redaction Studio in the media viewer: a body-cam video with its waveform marked for muting and bleeping, blur / black-box / blackout-frame controls, a 'Render redacted copy' action, and the synced transcript and visual timeline alongside.

07 · Discovery Check

Find what's missing.

Upload your discovery checklist. Arc matches what you have against what you should have — by filename, document type, entity, and narrative content. Surface the gaps before opposing counsel notices them.

ChargeStack Arc — Discovery Check: checklist matching dashboard showing total, confirmed, and per-item match scores.

08 · Ask Arc

Ask in plain English. Get cited answers.

Type your question. Arc reasons across the file using semantic search and document summaries, then answers with inline citations to the specific files it drew from. Tool calls visible, sources listed, per-question cost shown — nothing hidden behind a chat bubble.

ChargeStack Arc — Ask Arc agent interface: question with a cited multi-bullet answer, inline file citations, sources panel, and visible tool-call metadata.
