Task Sentry
Task Sentry · Other
Task Sentry is a free, AI-powered browser extension that blocks distracting websites at the moment you'd otherwise give in. Most focus apps rely on a static blocklist. Task Sentry reads the context of what you're doing and only steps in when a site would pull you off task. It works as a private website blocker too, because everything runs locally on your computer. So your browsing data never gets uploaded anywhere.
About Task Sentry
What Is Task Sentry
Task Sentry is a focus tool that takes a different angle from the classic website blocker. Most blockers work like a locked door, they cut off a fixed list of sites whether you need them or not. Task Sentry watches the situation instead. It understands the difference between watching a video for work and drifting into a random clip, then blocks the second case without touching the first.
It's built for people who find hardline blockers too rigid and self-control too unreliable. You set profiles and tasks. The extension then acts as an external bit of willpower that catches impulsive clicks in real time, which is the exact moment when a scheduled block or a locked list tends to fail you.
So who is it really for? Anyone who treats a distraction blocker as an AI focus tool rather than a locked door. The design leans on judgment, not force.
The biggest trade-off is that it leans on an on-device AI model, so quality depends on your machine rather than a cloud server. It's also a browser extension, which means it guards what happens in your browser and not apps running outside it.
Getting Started
- Install the Task Sentry extension in your browser from the official site.
- Create a profile that reflects how you work, such as "Deep work" or "Study".
- Add the tasks you want to focus on and the sites that tend to pull you away.
- Let the local AI watch your browsing and block distractions as they come up.
- Review what got blocked and fine-tune your tasks so the blocking stays accurate.

Key features
Context-Aware Blocking
Task Sentry doesn't just block a website. It looks at what you're doing when you open it. That makes it a smarter distraction blocker than a plain list, because a tutorial for a work task passes through while an unrelated clip gets blocked. That difference is the whole point. It means you keep the sites you actually need.
On-Device AI Processing
All the analysis happens on your own computer. Your browsing data isn't sent to a server or uploaded anywhere, which matters a lot if you're blocking sites tied to work or personal accounts. This on-device approach is also what earns it the AI website blocker label, since the intelligence sits in your browser rather than in the cloud. The trade-off is simple. Performance tracks your hardware, not a data center.
Profile and Task Setup
You organize blocking around profiles and tasks instead of one giant list. A "Study" profile and a "Deep work" profile can allow different sites, so the same browser behaves correctly depending on what you're doing. It's easy to run. The free plan covers one profile with five tasks, while the paid plan lifts both limits.
Real-Time Impulse Blocking
The extension reacts at the exact moment a distracting click happens. Not after the fact. That timing is what makes it useful on low-motivation days, when a daily report or a scheduled block wouldn't be enough, and it stays proactive in a way that tools you have to trigger yourself never quite manage.
Built for Distractible Minds
Task Sentry is pitched at people who are bright but easy to pull off course. Rather than a heavy system with dashboards and rules, it keeps the setup small and lets the guardrails do the work. Fewer moving parts means you're more likely to keep it running.
Pros and cons

Frequently asked questions
It's a browser extension that blocks distracting websites based on context. Unlike a fixed blocklist, it decides whether a site fits what you're working on right now and blocks it only when it doesn't.
