Know more before making contact. An AI-assisted Field Intelligence Platform for investigators and security professionals in the U.S. and Canada. Sentinel shows what the evidence supports, what is uncertain, and what to verify next. SAFETY BEFORE CONTACT The checks that matter most, right on the home screen. Choose United States or Canada: • Sex offender registries: NSOPW (U.S.); Alberta and Manitoba (Canada) • Wanted lists: FBI, U.S. Marshals, Secret Service and 26 state pages; Canadian police pages • Custody & release: VINE (U.S.) • Courts: PACER and CourtListener; CanLII Links open in your browser, with use rules shown where they apply. AI THAT SUPPORTS THE ANALYST AI does the first pass. The professional makes the call. • Field Brief: wanted and sanctions results, risk flags, identity confidence, and top checks before contact, in seconds • Full Analysis: findings, associations, contradictions, gaps, and sources • Web Brief: live web research written into a source-cited summary It flags what it cannot verify and treats a name match as unverified until confirmed. AI is powered by Anthropic's Claude. 19 OFFICIAL LISTS. CHECKED AUTOMATICALLY. FBI, Interpol, OFAC, UN, EU, UK, BIS, Canada, the U.S. Consolidated Screening List (including the SDN, Entity, and Denied Persons Lists) and the HHS OIG exclusion list. Results appear right after the search, before any AI: every match shows its list, match quality, source, data date and, where the list has them, identifying details. A check that cannot run is marked unavailable, never shown as a clean result. Sentinel is independent and not affiliated with or endorsed by any government. 150+ PUBLIC SOURCES. ONE WORKFLOW. Start with a name, phone, email, company, vehicle, domain, IP, or location. Guided research covers social media name searches, courts, FEC contributions, nonprofit filings, and more, without background-check sites. FIELD MAP Apple Maps with standard, satellite, and hybrid views, Look Around street-level imagery, address search, and case pins for Target, Staging, and Exit points, listed in the case PDF report (Pro). Photo GPS opens on the map. IMAGE FORENSICS Metadata, error level, compression, and hidden-data analysis for JPEG, PNG, and iPhone HEIC photos, plus an on-device SHA-256 hash of the original file. VEHICLES VIN decoding, U.S. and Canadian recall checks, and a CPIC stolen-vehicle link. CASE & FIELD INTELLIGENCE Cases, AI client intake, AI field note analysis, voice dictation, timelines, entity maps, evidence provenance, Watch List, and saved Field Briefs. PROFESSIONAL REPORTING Investigator, Executive Summary, Due Diligence, and Client-Ready PDF reports after a Full Analysis, with sources, methodology, limitations, and your own branding. LOCAL-FIRST PRIVACY Case data stays on your device, encrypted with AES-256-GCM, with keys in the iOS Keychain. Auto-lock, device integrity checks, and Wipe All Data (keys too). No ads. No tracking. AI requests, responses, and analyzed images are not kept on Sentinel's server. PLANS Same sources and security in both plans. • Essential: 20 AI analyses and 20 Web Briefs per month, 10 searches per day • Pro: 100 AI analyses (50 in the first 14 days) and 50 Web Briefs per month, no daily search cap, tool and case PDFs, AI client summary A Full Analysis counts as two. Monthly via Apple; cancel anytime. 7-DAY FREE TRIAL No card required; the trial never converts to a paid plan on its own. It includes 5 Field Briefs, 1 other AI analysis, 1 Web Brief, and 5 searches per day. Full Analysis requires Essential or Pro. WHAT SENTINEL IS NOT Not a people-search or background-check service; does not sell personal records. For lawful professional research. Not a consumer reporting agency; not for employment, tenant, credit, insurance, or other eligibility decisions.
