If you handle discovery in a criminal case, redaction is no longer an occasional chore — it is a recurring tax on every case. Bodycam footage with bystander faces, jail calls with spoken PII, scanned police reports with confidential informant details, and 911 call audio all need to be scrubbed before turnover, and doing it by hand in a PDF editor burns hours you do not have. AI redaction software promises to speed that up, but the tools on the market were built for very different buyers: some were designed for police departments clearing FOIA backlogs, some for firms redacting medical records, and only a few actually fit the defense workflow of reviewing evidence, redacting it, and citing it. This guide compares five tools attorneys are evaluating in 2026 — what each actually does, what it costs, and where each fits. We ranked Evidence Copilot first because it is the only option here built specifically for criminal-defense evidence review, where redaction is one step in a larger workflow of transcripts, citations, and human review rather than a standalone task.
#1 Evidence Copilot — Published pricing, no sales wall: Solo $39/user/mo (15 media-processing hours included), Firm $99/user/mo (60 hours, priority queue), PD Office $750/attorney/yr (100 hours). Overage is metered and hard-capped at 3x included hours. Every plan includes the full workspace — no feature tiers.
Evidence Copilot is a grounded evidence-review workspace built for US criminal-defense attorneys, law clerks, defense investigators, and public-defender offices — and redaction is designed to fit inside that workflow, not sit beside it. You upload the discovery dump: bodycam video, interrogation footage, jail calls, 911 audio, police reports, photos, and scanned documents. The platform produces timestamped, diarized transcripts and OCR'd document text, and an AI evidence agent answers questions with clickable citations into the exact second of video or page of a PDF. For redaction specifically, Evidence Copilot supports frame-accurate manual video redaction (drag a rectangle, choose black or blur), audio redaction where you pick the exact spoken words and that span is muted, plus image and PDF redaction. AI-suggested regions — bystander, victim, or minor faces, PII screens, license plates — file as suggestion cards marked "AI-suggested — needs review," and nothing is ever auto-applied. Every redaction produces a new derived file, originals are never touched, and every action is audited. That audit trail and original-preservation model matters for discovery turnover, where you need to show what was redacted and why. Beyond redaction, the same workspace handles multi-camera sync of bodycam, dashcam, and interview footage, auto-signals that surface candidate inconsistencies like report-vs-bodycam conflicts, suppression-motion and Miranda-timeline playbooks, and exhibit packs with a citation manifest. Every AI output is marked AI-generated and pending human review — the product never makes legal conclusions.
Pros
- Only tool on this list built specifically for the criminal-defense evidence workflow
- Nothing is auto-applied — AI suggestions require human review, consistent with ethics obligations
- Originals are never modified and every redaction action is audited
- Transparent published pricing with hard-capped overage; full workspace on every plan
- Redaction connects directly to transcripts, citations, and exhibit exports
Cons
- Defense-only by design — not built for prosecution or law-enforcement buyers
- Redaction is manual/assisted rather than fully automated bulk processing
- Newer product with a smaller track record than established redaction studios
Best for: Solo defenders, small firms, and public-defender offices that need redaction for discovery turnover as part of a full evidence-review workflow — transcripts, citations, inconsistencies, and motion prep in one place.
#2 CaseGuard Studio — Published comparisons list Doc at $99/mo, Lite at $199/mo, Standard at $249/mo, and Premium at $329/mo; the vendor also offers quote-based plans. Contact CaseGuard to confirm current pricing.
CaseGuard Studio is an on-premise desktop redaction application that handles video, audio, images, and documents in a single platform, with a strong footprint in law enforcement and government records offices. According to its website, the AI automatically detects and tracks faces, license plates, screens, and notepads across video, with blur, pixelate, or black-box options, and users can review AI detections before export. Audio redaction works through auto-transcription, letting users mute, bleep, or replace spoken PII in interviews, 911 calls, and bodycam audio, with transcription and translation in 100+ languages. For attorneys, the main draw is multimedia breadth: CaseGuard claims support for 750+ file types (its LawNext listing says 900+ document formats), OCR for scanned documents, bulk redaction of thousands of files, Bates numbering, and tamper-proof audit trails with customizable redaction reasons for FOIA, HIPAA, and CJIS-style compliance. A TeamSpace feature supports real-time collaboration, task assignment, and approval workflows. Because it is fully on-premise, sensitive files never leave your environment — a genuine strength for firms with strict data-residency concerns. The trade-offs are that it is desktop-only (no cloud or SaaS option, which limits remote collaboration), pricing is per-seat and scales with users, and it is a redaction studio rather than a case-review workspace: there is no grounded citation layer or defense-specific evidence-review workflow. Entry-level plans start around $99–$279 per month depending on tier, per published comparisons.
Pros
- Broadest multimedia format coverage of any tool reviewed
- On-premise processing keeps sensitive files fully under your control
- Strong bulk-redaction and audit-trail features for compliance-driven work
- Mature product with a large installed base in law enforcement and government
Cons
- Desktop-only — no cloud or remote collaboration option
- Redaction studio only; no transcript citation layer or case-review workflow
- Per-seat costs scale quickly for larger teams
- One published review notes it was flagged for lacking FIPS validation in a federal risk program
Best for: Firms and agencies with strict data-residency requirements that need high-volume multimedia redaction on local machines.
#3 VIDIZMO Redactor — Contact for pricing. Research indicates consumption-based (per processing unit) enterprise pricing with no published rate card; a free trial is available.
VIDIZMO Redactor is an enterprise-grade AI redaction platform covering video, audio, documents, and images in one interface, with research citing support for 255+ file formats. According to its website, it auto-detects 40+ PII types including PHI and PCI data, with country-specific patterns for the US, UK, Canada, India, and the EU, and supports OCR for scanned documents plus ICR for handwritten text. Bulk processing has been tested at over two million recordings, and full audit trails document every redaction decision — who, what, and when. What sets VIDIZMO apart for legal teams is deployment flexibility: SaaS, government cloud, on-premises, Azure Government Cloud, and hybrid environments. That matters for firms handling government contracts or matters with data-sovereignty constraints that rule out cloud-only tools. Role-based access controls, chain-of-custody logs, and transcript-based audio PII masking round out the compliance picture, and the platform is positioned around legal workflows including eDiscovery, privilege review, and court-ready evidence preparation. The honest caveats: it is built for multi-format, high-volume workflows, so a document-only or small-firm team will use a fraction of what it offers. Pricing is consumption-based (per processing unit), which requires estimating your volume upfront, and published comparisons characterize it as enterprise-level pricing with no public rate card. For a solo defender or small PD office, it is likely more platform than the redaction problem requires — but for a large firm or agency with mixed media and strict compliance needs, it is one of the most complete options available.
Pros
- Broadest deployment flexibility on this list, including government cloud and hybrid
- Handles very high volumes across all media types in one platform
- Strong compliance documentation: audit trails, chain of custody, role-based access
- Free trial available to test on your own files
Cons
- Enterprise-oriented; overkill for solo practitioners and small firms
- Consumption-based pricing requires estimating processing volume upfront
- No published pricing — budgeting requires a sales conversation
- Document-only teams will pay for multimedia capability they may not use
Best for: Large firms, courts, and government-adjacent legal teams processing high volumes of mixed-format files with HIPAA-level compliance and flexible deployment requirements.
#4 Redactable — Starts at $29/month according to one published review; other 2026 comparisons list entry plans around $19/month. Contact Redactable to confirm current tiers.
Redactable is a cloud-based, AI-powered redaction platform focused on documents — primarily PDFs and text-based files. According to its website and published comparisons, it permanently removes sensitive data and hidden metadata in one step (rather than visually masking it), uses AI to detect PII, and generates full audit trails for compliance. Published reviews state its AI can detect personally identifiable information significantly faster than manual methods, and the platform supports real-time collaboration with integrations into Clio, Google Drive, Dropbox, and Box. For attorneys, Redactable fits the document-heavy side of practice: court filings subject to FRCP 5.2 partial-redaction requirements, discovery PDFs, medical records, and client documents. Its interface is frequently described as clean and quick to onboard, which matters when paralegals and law clerks — not IT staff — are doing the redaction. An API is available for connecting to existing document management systems. The limitations are clear and worth stating plainly: it is documents only — no video, audio, or image redaction — so it cannot touch bodycam footage, jail calls, or 911 audio. It is SaaS-only with no on-premises deployment option, and published comparisons note no CJIS or FedRAMP compliance, which limits use for government-adjacent work. Pricing starts around $19–$29 per month according to published 2026 comparisons, making it one of the most accessible entry points for small firms whose redaction workload is paper-shaped.
Pros
- Permanent redaction with metadata removal, addressing the classic black-box failure
- Low, accessible pricing for small firms and solos
- Fast onboarding with a clean, document-focused interface
- Native Clio integration fits existing practice-management stacks
Cons
- Documents only — no video, audio, or image redaction whatsoever
- Cloud-only; no on-premises option for data-residency-sensitive matters
- No CJIS or FedRAMP compliance per published comparisons
- AI processing means documents leave your local environment
Best for: Small firms and legal teams whose redaction workload is documents and PDFs — court filings, discovery productions, medical records — and who are comfortable with a cloud-only platform.
#5 Secure Redact (Pimloc) — Contact for pricing. No published rate card was found in research.
Secure Redact, built by Pimloc, is an AI-powered platform focused on video and audio redaction, designed for high-volume footage from bodycams, CCTV, and dashcams. According to its website, it automatically detects faces, license plates, screens, and documents in view, and offers AI-driven audio transcription with redaction of spoken names, places, and dates — a capability most video-only tools lack. It claims detection accuracy above 99% and supports SaaS, API, private-cloud, and on-premise deployment, with integrations into digital evidence management systems. For attorneys, Secure Redact fits when the redaction problem is footage-shaped: preparing bodycam or interview video for disclosure, court use, or media release where bystander faces and spoken identifiers must be removed. Batch processing handles large backlogs, and published reviews highlight full audit trails and preservation of originals as strengths for evidential integrity. One 2026 legal-tech comparison notes its ISO 27001-certified security posture and irreversible redaction aligned with data-minimization requirements. The limitations for a defense practice are significant, though: Secure Redact is video and image focused — published comparisons note no document or PDF redaction — so it cannot handle scanned police reports or paper discovery. It has limited presence in the US legal market and no US government certifications (CJIS, FedRAMP) per one comparison, and it is built primarily for law-enforcement and agency buyers rather than defense workflows. There is also no transcript citation layer connecting redactions back to case review. As a focused video-redaction engine, though, it is among the strongest options available.
Pros
- Strong purpose-built video detection with audio redaction of spoken PII
- Flexible deployment including on-premise and API access
- Audit trails and original preservation support evidentiary integrity
- Scales to large backlogs via batch processing
Cons
- Video and image only — no document or PDF redaction per published comparisons
- Limited presence in the US legal market; no CJIS/FedRAMP certifications noted
- Oriented toward law-enforcement and agency buyers, not defense case workflow
- No published pricing; budgeting requires contacting sales
Best for: Teams whose redaction workload is primarily video and audio — bodycam, CCTV, interview footage — and who need high-volume, evidence-grade processing.
Redaction software in 2026 splits into two camps: standalone redaction engines built for agencies and document-heavy firms, and workspaces where redaction is one step inside evidence review. If your redaction work is mostly PDFs for filings, Redactable is an affordable, capable choice. If you are clearing footage backlogs for an agency or need on-premise multimedia processing, CaseGuard or Secure Redact fit. For large mixed-format compliance work, VIDIZMO is the enterprise option. But if you are a criminal-defense attorney, the real question is not which tool redacts fastest — it is whether redaction connects to everything else you do with discovery: diarized transcripts, report-vs-bodycam inconsistencies, suppression-motion prep, and exhibits you can cite down to the exact second. That is why Evidence Copilot leads this list. Every AI answer cites its exact source moment, every output is marked pending human review, originals are immutable, and pricing is published — Solo at $39/user/mo, Firm at $99/user/mo, PD Office at $750/attorney/yr — with no feature tiers and no sales wall.

Frequently asked questions
What is AI redaction software and how is it different from drawing black boxes in a PDF editor?
AI redaction software automatically detects sensitive information — faces, license plates, spoken names, Social Security numbers, dates of birth — across video, audio, and documents, then permanently removes it from the file rather than covering it visually. This matters because a black box drawn over text in a basic PDF editor often leaves the underlying text extractable via copy-paste or text-extraction tools, which has led to court sanctions. Proper tools modify the file's content streams, strip metadata, and log every redaction in an audit trail so the work is defensible.
Can AI redaction be fully automated, or does an attorney still need to review everything?
Even the strongest tools require human review. AI detection catches the majority of identifiers, but complex scenes, partially obscured faces, and context-dependent judgments (like whether a bystander is a witness who must be protected) still need a person making the final call. Evidence Copilot takes this further by design: AI-suggested redaction regions file as suggestion cards marked "AI-suggested — needs review" and nothing is ever auto-applied. For defense attorneys bound by ethics rules on client confidentiality and discovery obligations, that human-in-the-loop posture is a feature, not a limitation.
What should criminal-defense attorneys look for when choosing redaction software for discovery turnover?
Prioritize five things: (1) originals are preserved and every redaction is audited, so you can show what was changed and why; (2) both visual redaction (faces, screens, plates in bodycam video) and audio redaction (spoken PII in jail calls and 911 audio) are supported; (3) OCR handles scanned police reports and photo evidence; (4) redaction connects to the rest of your review — transcripts, citations, and exhibit exports — rather than living in a separate tool; and (5) pricing is transparent, since redaction volume varies wildly case to case and metered overage should be capped, not unlimited.
How much does AI redaction software cost in 2026?
It varies widely by buyer type. Document-focused tools like Redactable start around $19–$29/month per published comparisons. CaseGuard's published tiers run roughly $99–$329/month depending on plan. Enterprise platforms like VIDIZMO use consumption-based pricing with no public rate card. Evidence Copilot publishes its pricing openly: Solo at $39/user/mo with 15 media-processing hours, Firm at $99/user/mo with 60 hours and a priority queue, and a PD Office tier at $750/attorney/yr with 100 hours — with overage hard-capped at 3x included hours so runaway intake cannot overbill, and the full workspace included on every plan.
Does Evidence Copilot auto-redact faces and PII in bodycam footage?
Evidence Copilot provides AI-suggested redaction regions — bystander, victim, and minor faces, PII screens, and license plates — but files them as suggestion cards marked "AI-suggested — needs review." Nothing is ever auto-applied. The attorney or reviewer drags a frame-accurate rectangle and chooses black or blur for video, selects the exact spoken words to mute in audio, or redacts images and PDFs directly. Every redaction creates a new derived file, originals are never touched, and every action is audited.
Is redaction software secure enough for privileged case files?
Security posture varies by tool, so verify directly with each vendor. Key questions to ask: where is data processed and stored, is data used to train AI models, what encryption and access controls exist, and what audit records are produced. On-premise options like CaseGuard keep files entirely in your environment; cloud tools like Redactable and VIDIZMO publish encryption and compliance documentation. Evidence Copilot takes a workflow-level approach: originals are immutable, every action is audited, exports are gated by per-member export permission, and its MCP integration is read-only, org-scoped, revocable, and fully audited. The company is candid about its current security posture rather than claiming certifications it has not earned.
Why is Evidence Copilot ranked first over tools with more automated redaction features?
Because ranking depends on the job. For an agency clearing a FOIA backlog, a bulk-redaction studio is the right tool. But for criminal-defense work, redaction is rarely the whole task — it is one step in reviewing 40 hours of bodycam, finding report-vs-bodycam inconsistencies, prepping a motion to suppress, and building exhibits. Evidence Copilot is the only tool on this list built for that entire defense workflow, with timestamped diarized transcripts, an AI agent that cites the exact video second or PDF page, multi-camera sync, suppression-motion and Miranda playbooks, and exhibit packs with citation manifests — with redaction integrated into the same audited, original-preserving workspace. If your only need is standalone bulk redaction, a specialist tool may fit; if redaction is part of case prep, it belongs in the workspace where the rest of the work happens.
