Sentra is the first safety platform built specifically for AI chatbot monitoring — watching ChatGPT, Character.AI, Claude, Gemini, Replika, and Copilot for patterns that signal risk, so you don't have to become a cybersecurity expert overnight.
Kids today grow up beside AI companions, algorithm-driven platforms, and strangers that know how to find them. Traditional parental controls — built for a simpler web — can't see what matters anymore.
Teens share secrets with ChatGPT and Character.AI that they'd never share with parents — including emotional distress.
Deepfaked images and voice clones are now a weapon in schoolyards. Most parents have no idea it's happening.
Predators have mastered the language of gaming, fandoms, and TikTok trends. Grooming takes weeks, not minutes.
Hidden in that number: sleep lost, anxiety rising, and social media apps that are engineered to be addictive.
Sentra's Chrome extension runs silently on your child's browser, monitoring the AI chatbots they actually use. You only hear from us when something matters.
The world's first system designed specifically for AI chatbot safety. Sentra watches interactions with ChatGPT, Character.AI, Replika, and emerging AI tools — detecting emotional manipulation, unsafe advice, jailbreak attempts, and unhealthy dependency before patterns become problems. We don't read messages. We read behavior.
Catches when your child tries to instruct an AI to ignore its own safety rules. Consistent red flag for what they're actually searching for — surfaces on your dashboard immediately.
Detects romantic roleplay and parasocial attachment forming with AI personas on Character.AI and Replika — flagging escalating emotional investment before it becomes dependency.
Identifies when a child increasingly confides in AI instead of people — tracking session frequency and patterns without reading message content. Sentra never sees what's said.
Detects requests about self-harm, eating disorders, drug use, and dangerous instructions — the kinds of questions teens ask AI because they're afraid to ask anyone else.
Tracks when, how long, and how often your child uses each AI platform. Late-night sessions, sudden spikes, or compulsive daily use surface as signals on your dashboard.
When a signal crosses a threshold, you get an email immediately. No dashboards to remember to check — alerts come to you with context, on your schedule.
All your children, all their connected browsers, one calm view. See recent AI signals, weekly summaries, and connection status without logging into three different places.
Legacy parental controls treat AI apps like regular apps. But a chatbot isn't like TikTok — it remembers everything, speaks with authority, and forms a relationship. That changes the safety conversation entirely.
Sentra is the only platform with a dedicated AI-safety engine built specifically to monitor the chatbots kids actually use — not general-purpose content filters adapted from an older internet.
Four steps from sign-up to live monitoring — no technical skills required, no configuration that takes an evening.

Multi-parent access, unlimited devices, and our expert AI coach for tough parenting conversations.
Sentra is built on the principle that surveillance isn't safety. We detect patterns, not content. We inform children honestly. We store as little as possible.
Our AI pattern-matching runs inside the browser extension itself. Only the alert type and risk score ever leave the device — never the text that triggered it. We literally cannot read your child's messages.
Secret surveillance erodes trust. Sentra is visible to your child and includes their own simple view of what's being monitored.
We store only behavioral metadata, never content. All data for minors is automatically purged after 90 days. Fully compliant with every major child data protection standard.
All data is encrypted between the extension, our servers, and your dashboard. Signal metadata is stored securely and never shared with third parties.
Sentra focuses on the browser — where kids use ChatGPT, Character.AI, Replika, Claude, Gemini, and Copilot on school Chromebooks and home laptops. Mobile app monitoring is on the roadmap.
One tap wipes your family's data from our servers permanently. No dark patterns. No "are you sure?" guilt trips.
