Know more before making contact. Sentinel is an AI-assisted Field Intelligence Platform that turns fragmented public-source findings into a structured, reviewable intelligence picture before contact or action. Built for investigators, security professionals, due diligence teams, process servers, executive protection practitioners, corporate investigators, and other professionals, Sentinel combines guided research, AI-assisted analysis, professional review, and case workflow on iPhone and iPad. Start with what you have: a name, phone number, email address, company, vehicle, domain, IP address, location, or another available identifier. AI-ASSISTED INTELLIGENCE WORKFLOW Sentinel identifies the target type, recommends an appropriate research path, organizes findings, prioritizes critical information gaps, and helps determine what should be verified next. Understand: β€’ What is supported by available evidence β€’ What may be a possible association β€’ What remains uncertain or contradictory β€’ What may indicate potential risk β€’ What information is missing β€’ What should be verified next AI-assisted capabilities include research planning, evidence classification, source reconciliation, gap prioritization, confidence explanation, alternative hypotheses, analytical quality checks, query assistance, manual-source guidance, and change summaries. PRE-CONTACT INTELLIGENCE BRIEF Sentinel transforms findings into a structured Pre-Contact Intelligence Brief that may include: β€’ Identity and assessment overview β€’ Confirmed and supported findings β€’ Possible associations β€’ Potential risk indicators β€’ Identity ambiguities and contradictions β€’ Alternative explanations β€’ Critical information gaps β€’ Recommended verification β€’ Operational considerations β€’ Confidence explanations and limitations β€’ Supporting evidence and source references Choose a rapid 10-second overview, an operational view, or the full analytical brief. AI SHOULD EXPOSE UNCERTAINTY, NOT HIDE IT Sentinel does not simply generate an AI answer. It keeps evidence, uncertainty, contradictions, information gaps, and limitations visible throughout the workflow. A name match is not an identity. An association is not confirmation. A potential risk indicator is not a conclusion. Missing information affects confidence. AI supports the analysis. Professional judgment remains in control. PROFESSIONAL REVIEW AND CONTROL Review findings, confirm or reject possible associations, mark information for further verification, exclude irrelevant findings, add professional notes, and regenerate the brief using reviewed information. Version history records how an assessment changes as new identifiers, findings, or professional decisions are added. Track assessments through Draft, Verification Required, Ready for Review, Reviewed, and Locked. CONNECTED CASE WORKFLOW Save assessments to cases and keep findings, notes, tasks, timelines, maps, reports, and activity history connected to the investigation. Create professional PDF reports with assessment status, source references, review information, timestamps, limitations, and audit history. BUILT FOR MOBILE FIELD USE Designed for iPhone and iPad, Sentinel lets professionals begin, review, and continue intelligence work wherever the assignment takes them. LOCAL-FIRST DATA CONTROL Case information, notes, reports, and investigation activity remain under the user’s control through Sentinel’s local-first architecture and device security features. 7-DAY FREE TRIAL Try Sentinel Pro free for 7 days. AI analysis is limited during the trial. Pro subscribers get unlimited AI analysis. Sentinel supports lawful professional research and informed decision-making. It is not a consumer reporting agency and is not intended for employment, tenant, credit, insurance, or other regulated eligibility decisions.
