Rev

Rev is the Investigative Platform that turns digital evidence into a searchable, citable record, built for attorneys, prosecutors, law enforcement, and investigators who are drowning in evidence. Body-worn camera footage, dash cam video, jail calls, 911 recordings, witness interviews, photos, and depositions pile up faster than any team can review by hand, and Rev exists to close that gap between the evidence teams have and the time they have to work through it. Rev combines industry-leading speech recognition, purpose-built for the hardest audio environments in legal and law enforcement, with AI that cites every finding back to a timestamp or image in the original source file. Nothing is generated without being verifiable. That distinction matters: legal transcription accuracy is table stakes, but a citation that can't be traced back to the record isn't useful in a courtroom, a suppression hearing, or an internal affairs review. Every result Rev produces is built to hold up under that kind of scrutiny. What sets Rev apart is what happens after transcription. Investigators and attorneys can search across dozens of files at once instead of reviewing one recording at a time, surfacing the inconsistency or the corroborating detail before opposing counsel or the other side finds it first. Rev also analyzes images and video stills for relevant visual evidence, and it drafts reports, memos, and case documents directly from the record, cutting down the time spent moving information from a recording into a usable document. All of this happens without replacing the judgment of the professional responsible for the case. Rev keeps humans in control by design, and when precision is non-negotiable, optional human review adds another layer of assurance. Security is built in, not bolted on. Rev meets CJIS, HIPAA, and SOC 2 compliance standards and shares zero data with third-party LLMs. Evidence stays in a closed loop, and nothing trains a third-party model, ever. That makes Rev usable in environments where general-purpose AI tools create real ethical and security risk for legal and investigative teams working with sensitive case data. The result is faster case review, fewer missed details, fewer overtime hours, and more time spent on analysis and decision-making instead of playback and paperwork. Responsibility for judgment stays exactly where it belongs, with the people trained to exercise it.

Dictation Daddy

Dictation Daddy is an AI voice dictation app built for professionals whose work depends on writing — lawyers, doctors, researchers, and knowledge workers who need to turn speech into accurate, ready-to-use text faster than they can type. Most professionals lose hours every week typing notes, drafting documents, and updating records. Native operating system dictation is inaccurate, generic, and prone to errors with industry vocabulary. General-purpose transcription tools weren't built for the precision that legal briefs, medical charts, or client communication demand. Dictation Daddy was built to close that gap — with state-of-the-art speech-to-text accuracy, intelligent AI cleanup that removes filler words and structures rambling thoughts into polished prose, and domain-aware vocabulary that recognizes legal terminology, medication names, anatomical references, and the specialized language of your practice. For legal professionals, Dictation Daddy supports rapid drafting of memos, briefs, client correspondence, deposition summaries, and case notes — with custom vocabulary for case names, statutes, and parties, plus reusable templates for common document types. Built with the confidentiality requirements of law firms in mind, including support for DPAs and contractual safeguards for client-sensitive work. For doctors and clinicians, Dictation Daddy accelerates SOAP notes, patient summaries, referral letters, and chart documentation — with medical vocabulary support and a whisper-detection mode that lets you dictate quietly in shared clinical spaces without raising your voice. BAA support is available for healthcare practices handling protected health information. Dictation Daddy works everywhere you do. Native apps for Mac, Windows, Android, and iOS (beta) let you dictate into any application — word processor, email, EHR, case management system, or browser. The Chrome extension brings the same accuracy to web-based tools like Clio, Practice Fusion, Gmail, Notion, and Google Docs. A simple keyboard shortcut activates dictation in any text field — no copy-paste, no app switching, no breaking your flow. Additional capabilities include file upload transcription for converting recorded dictations, interviews, depositions, or meeting recordings into accurate text; custom AI cleanup prompts for matching your firm's or practice's preferred tone; and a credits-based pricing model that scales with usage. Trusted by solo practitioners, small firms, and clinical teams who chose Dictation Daddy over generic AI dictation tools because their work demands more than autocorrect — it demands a tool that understands what they're saying and how it needs to read. Try Dictation Daddy free, then upgrade when voice becomes your primary input.
