Crypt Secure vs Sentinel

CRYPT is a powerful, modern encryption sandbox that lets you encode messages, decode secret text, and manage fully custom keys — all locally on your device. No accounts, no servers, no tracking. Just pure, offline cryptography you control. Whether you’re exploring ciphers, protecting sensitive text, or experimenting with encryption systems, CRYPT gives you a clean, intuitive interface with full control over your keys and output.

Know more before making contact. Sentinel is an AI-assisted Field Intelligence Platform for investigators and security professionals who need more than search results. Finding information is only the beginning. Professional intelligence starts with verification. Sentinel combines broad public-source research with publicly available government, law-enforcement, regulatory, and international sanctions data, then helps structure what the evidence supports, what remains uncertain, and what to verify next. AI THAT SUPPORTS THE ANALYST Intelligence and security organizations increasingly use AI to sort, connect, and summarize large volumes of information. Sentinel brings that approach to field professionals, with one rule: AI does the first pass, the professional makes the call. - Field Brief: wanted and sanctions results, risk flags, identity confidence, and the top checks before contact, in seconds - Full Analysis: confirmed findings, possible associations, contradictions, information gaps, and source references - Web Brief: live web research written into a source-cited summary, combined with what Sentinel has already found Sentinel's AI states what it cannot verify, treats a name match as unverified until identity is confirmed, and never merges different people into one identity because they share a name or username. AI analysis is powered by Anthropic's Claude models. START WITH ONE IDENTIFIER Begin with a name, phone number, email, company, vehicle, domain, IP address, or location. Sentinel routes the research, organizes findings, and identifies gaps. 130+ PUBLIC SOURCES. ONE WORKFLOW. Automated wanted and sanctions screening against FBI, Interpol, OFAC, UN, EU, BIS, and Canadian lists, plus guided research across 130+ public sources. A check that cannot run is marked unavailable, never shown as a clean result. EVIDENCE PROVENANCE Finding → Source → Verification Status → Professional Decision. Mark findings Confirm, Reject, or Review. ENTITY RESOLUTION & IMAGE FORENSICS Map relationships between people, phones, emails, companies, addresses, vehicles, and domains with calibrated confidence. Analyze images for metadata, error level, compression and hidden-data indicators, without declaring an image authentic or manipulated from a single indicator. CASE & FIELD INTELLIGENCE Cases, AI field note analysis, voice dictation, timelines, maps, tasks, Watch List change detection, and saved Field Briefs. PROFESSIONAL REPORTING Investigator, Executive Summary, Due Diligence, and Client-Ready PDF reports with sources, methodology, limitations, and your own branding (Pro). 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, which also destroys the encryption keys. No ads. No tracking. AI requests pass through Sentinel's server, which does not store your search terms or AI responses. PLANS Essential and Pro use the same sources, methodology, and security. Pro adds capacity and advanced reporting. - Essential: 20 AI analyses and 20 Web Briefs per month, 10 searches per day - Pro: 100 AI analyses and 50 Web Briefs per month, unlimited searches, all report types and branding Monthly subscriptions through Apple. Cancel anytime in your Apple account settings. 7-DAY FREE TRIAL No card required, and 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 Sentinel is not a people-search or background-check service and does not sell personal records. It is for lawful professional research. Not a consumer reporting agency; not for employment, tenant, credit, insurance, or other eligibility decisions.
