The Leading Investigative Platform for Secure, Accurate Evidence Review

As the trusted leader in legal transcription and AI-powered discovery analysis for state and local government agencies, Rev transforms hours of audio, video, and discovery materials into accurate, searchable, and analyzable transcripts — reducing review time by up to 94%.

Designed for investigative precision, Rev combines accurate legal transcription with AI-powered chat, search, and review to enable faster discovery processing. Plus, everything uploaded to Rev is covered by a secure, privilege-protecting infrastructure. Rev users maintain full ownership and control of their data - their information is never used to train third-party AI models. Rev is SOC 2 Type II, HIPAA and CJIS compliant, ensuring confidentiality throughout every stage of the investigative process.

Rev was created to help fix the pain points of traditional evidence review. Law enforcement agencies, investigators, district attorneys, and public defenders all lose valuable time scrubbing through recordings, interviews, and body cam footage — time that should go toward strategy and case evaluation. Rev changes that by making the entire case searchable, centralized, and defensible:

  • Centralize every file. Bulk file upload and structured workspaces for different cases eliminates the need to jump between systems.
  • Find what matters fast. Surface contradictions, key facts, and critical insights instantly across multiple evidence types at once.
  • Defend every decision. Generate reports and summaries with verifiable citations directly tied to the original evidence source.
  • Reduce burnout. AI-powered transcription and evidence empower teams to find key moments faster without getting bogged down in manual searches.​​​​​​​​​​​​​​​​​
  • Protect privilege. Rev acts as a secure, trusted service provider — preserving attorney–client confidentiality and agency integrity.

What Sets Rev Apart:

  • Accuracy First: 47% more accurate than major global providers (Google, Amazon, Microsoft), with optional human verification for court-level defensibility.​​​​​​​
  • Privilege-Protecting Security: Attorney–client confidentiality upheld; Rev refuses all third-party data requests without explicit consent.​​​​​​​
  • Zero Third-Party Data Training: User data is never used to train external AI models.​​​​​​​
  • Discovery at Scale: Handles large, complex evidence sets across multiple file types seamlessly — no file size or upload limitations.​​​​​​​
  • Defensible AI: All outputs include timestamped citations tied to verifiable evidence sources — never hallucinated content.

Since 2010, Rev has processed over 7 billion words and developed proprietary models purpose-built for sensitive legal environments. Backed by SOC 2 Type II, HIPAA, and CJIS compliance, Rev provides a secure, accurate, and defensible foundation for justice professionals to uncover the truth and achieve fair, just outcomes. Trusted by leading law enforcement agencies and technology partners like Axon and AM Law 200 firms nationwide, Rev continues to set the standard for secure, high-accuracy speech intelligence in public safety and legal investigation.
