Sentenial® is a plug-and-play firewall that protects children from cyberbullying, grooming, and harmful content redirection!
Worried your child could be bullied, groomed, or harassed — and you wouldn’t even know?
Sentenial gives you eyes where there were none.
A private AI firewall that flags dangerous behaviour, alerts you instantly, and helps you protect your child — without invading their privacy.
Early access benefits include
Without giving too much away, here’s what makes Sentenial so unique:
Just Plug It In. Pair. Protect.
Sentenial connects to your home broadband and starts protecting your family instantly, no technical knowledge needed
You pair your phone using a secure QR code — no accounts, no cloud.
The system then works silently in the background, flagging harmful patterns and alerting you when your child needs you most.
At Sentenial, our mission is to empower everyday families with the tools to protect their children in the digital age, without compromising privacy, control, or trust.
We believe:
Parents shouldn’t need to be IT experts to protect their kids.
Privacy should be the default — not an upsell.
Safety tools should work even without the cloud.
We exist to protect.
We exist to empower.
We exist to make the internet safer, one home at a time.
Why It Matters
Over 1 in 5 children in the UK experience cyberbullying.
(Ofcom & Anti-Bullying Alliance, 2023)
Children aged 8–15 spend an average of 3–5 hours per day online.
(Ofcom Media Use and Attitudes Report, 2023)
Online grooming crimes have tripled in the past five years in the UK.
(NSPCC, 2023)
Almost 1 in 3 UK parents don’t use any parental control tools — often because they’re too complex or invasive.
(Internet Matters, 2022)
Nearly half of UK children aged 11–13 say they’ve seen harmful or disturbing content online.
(Children’s Commissioner for England, 2023)
Sentenial is here to stop the damage before it happens, with offline AI, privacy-first design, and no accounts required.
Built using open-source tech like Home Assistant, UFW, FastAPI, and Flutter
We’re in the late prototyping stage now, with private testing underway.
Early backers will be the first to receive updates, exclusive invites, and priority access when we launch.
Why Offline AI?
Most tools rely on the cloud, which means your child’s data is stored, analysed, and sometimes even shared.
Sentenial runs AI locally, on the device, giving you all the safety with none of the surveillance.
We’re not backed by a corporation.
We’re backed by a cause.
Sentenial is being built with love, integrity, and determination — by someone who knows what it means to be a parent in a digital world.
Let’s make the internet safer — one family at a time.
