Sherlock Warrants is built for sworn law enforcement officers. Verified access only. The warrant is the hardest paperwork in policing: the statutes, the structure, the format the court expects, the hours it takes to get all of it exactly right. Sherlock was built for that job first. You bring the probable cause. Sherlock builds the warrant around it. Talk to it or type to it. Say "Hey Sherlock" and tell it what you need on the case you are already working: "On my homicide case, I need call detail records and timing advance locations for the suspect's Verizon phone." Sherlock picks the correct warrant family, asks for the precise records from the right provider, and writes a complete, court-ready application and affidavit around the probable cause statement you supply. Statutes quoted word for word, formatted the way your court expects. Sherlock never writes your probable cause and never decides your legal grounds. Those are yours. It does the clerical work, so you can do the police work. With your probable cause statement ready, the draft comes back in about two minutes. Review it, edit right on the page, print it or export it. TWO WAYS TO WRITE InstaWrite: One tap. A complete, court-formatted warrant for your warrant type and provider appears instantly, statutes and items to be seized already in place. Add your case specifics, trim what does not apply, sign. Build: Want to be walked through it? Build asks for exactly what the warrant needs, field by field, and writes it in finished form. BUILT FOR THE WARRANTS YOU ACTUALLY WRITE Person, place, thing and vehicle searches. DUI blood draws. GPS vehicle trackers. Cellphone pings. Tower dumps. Arrest warrants. In all, 35 warrant families across 7 categories. Not sure which one? Describe what you need and Sherlock selects the family for you. ANY PROVIDER, THE RIGHT RECORDS 150 named providers across 19 categories: phone carriers, social media, banks, rideshare, doorbell cameras and more. Every warrant comes populated with the current items to be seized for that provider, plus the legal process address and service details preloaded, so you ask for the right records and the warrant lands exactly where it has to go. Provider not on the list? Sherlock looks it up on the spot. SAY "HEY SHERLOCK" Hands free, in the field or at the desk. Tell it what you need and keep moving. YOUR LIBRARY, ORGANIZED BY CASE Every warrant you write is saved to your Library and tied to its case number. Working a case that needs more than one warrant? Start the next one from the last one. Sherlock carries the case details forward, so the suspect, the location, and the facts you already entered are waiting. The second warrant on a case takes minutes, not another evening. Your whole filing history, on your phone or on the web. FREE. VERIFIED ACCESS ONLY. Free for sworn officers and authorized civil investigators. No cost to you, no cost to your agency. Supported by a small group of vetted sponsors. Every account is identity verified before access is granted. Sherlock Warrants accepts no crime reports, tips, or complaints from anyone, and transmits nothing to any law enforcement agency. It is a drafting tool for the officer who is already assigned the case. SECURE BY DESIGN Runs in a secure United States government cloud environment built for criminal justice information, architected to the FBI CJIS Security Policy, with your data encrypted in transit and at rest. Launching in Arizona. More US jurisdictions on the way. Less paperwork. More police work. Sherlock Warrants is a drafting assistance tool. All output is a draft for review. The sworn officer or authorized investigator is solely responsible for verifying the accuracy, completeness, and legal sufficiency of every document before signing or submitting it to a court. Sherlock Warrants does not provide legal advice. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
