Detects explicit images & video
Every image and video is checked as they download. Explicit content is swapped for a blurred copy or blocked completely while the rest of the page loads normally.
Kellet blocks porn across every browser and app on your device. Built-in AI detection blurs or blocks explicit images and video in real time, even on websites other blockers miss. Built-in tamper protection ensures you can’t simply switch it off when temptation strikes.
Every feature on for 14 days. No card needed. Windows 10 and 11.
You asked to allow Adult content
Requested at 00:41. The block stays exactly where it is until the timer ends.
If it has an off switch or a workaround, it’s not good enough.
Most blockers have an off switch, or a session that simply ends.
Two taps and the blocker was gone, and your willpower along with it.
The browser extension guarded Chrome, but Firefox was already installed.
A blocklist only knows the sites someone has already reported.
Most blockers only look for nudity, so swimwear, lingerie, feet and fetish content get straight through.
Search engines, social media, and video platforms give you plenty of ways to find content you thought you blocked.
A browser with its own VPN carries its traffic straight past a network filter.
Blockers filter what comes in from the internet. Photos and videos already saved on the device never touch the web, so they are ignored completely.
Blocking porn should never depend on willpower. If it were that simple, you wouldn’t be here.
Every image and video is checked as they download. Explicit content is swapped for a blurred copy or blocked completely while the rest of the page loads normally.
Kellet's AI scans your screen as often as every few seconds, detecting explicit content across websites, apps, and videos, even when traditional filters can't see it.
Multiple actively maintained adult lists detect and block explicit domains.
Google, Bing and DuckDuckGo always use strict SafeSearch, and YouTube always runs in Restricted Mode.
Add the words, names and phrases you want stopped. A search containing one is blocked before the results load, on Google, Bing, YouTube, Reddit, X, TikTok and more, including searches made inside sites like Facebook.
Block a program, give it a daily limit, or hold anything newly installed until you approve it. Scheduled blackouts close everything for the hours you name.
You decide what Kellet does the moment it detects porn, and what happens if you keep going.
Swap the page for a block page in your own words, or send the browser somewhere safe.
Shut the tab it was on, straight away. Everything else stays open.
Close every window and every tab. Whatever was on screen is gone.
Escalations allow you to lock the device when detections pile up. Each lock lasts longer than the last.
Tightening a rule takes effect immediately. Loosening one waits out the delay you chose in calmer waters.
Download, sign in, and Kellet starts as a Windows service. Explicit content is blocked from the first minute, in every browser.
Decide how long any loosening has to wait, and set a longer wait for uninstalling if you like. You pick the number while nothing is pulling at you.
Kellet takes the request, starts the clock and leaves the block exactly where it is. When the moment has passed, cancel the request in one click.
Invite a spouse, sponsor or friend as an accountability partner. They see your activity, you choose what they can approve or change, and they never pay a penny.
Many accountability tools work by reporting your activity to someone else. Kellet focuses on preventing it in the first place, while keeping your activity history private by default.
Images and the screen are checked by a model running on your own device, not by a cloud service.
No one looking over your shoulder. Your activity history stays in your account, and you decide who gets to see it.
Invite someone you trust to see your activity. You decide what they can manage, and you can revoke their access, straight away or after a delay you choose.
Kellet is designed to avoid decrypting sensitive traffic, including banking, healthcare, and password managers.
Kellet is built for your own devices. There is no covert install and no hidden mode, and it is not a parental control app. On a shared PC, get the agreement of everyone who uses it before you install.
Kellet runs on Windows today. Android and macOS land in Q4 2026, and iPhone and iPad in Q1 2027.
One subscription covers every Windows device you own. No device limits, no extra fees. Try Kellet free for 14 days, with every feature unlocked and no credit card required. The 14 days start when you add your first device, not when you sign up. Your settings, history, and progress stay in place if you decide to subscribe.
If someone adds you as their accountability partner, your side costs nothing, forever.
Not for you? Ask within 30 days of paying and we refund it in full.
Pick a plan, or blocking stops on the day the trial ends. Your rules, your history and your clean streak stay put.
Not in the moment. There is no off switch and no pause. You can loosen any rule, but the change waits out the cool-down you set. Making a rule stricter takes effect straight away.
You can. It's your PC. Uninstalling is a request that waits out its own cool-down, which you can set longer than the others. If you set no delay, it removes straight away.
Yes. Kellet is a Windows service, not a browser extension, so it filters the whole PC. Chrome, Edge, Firefox, Brave, Opera and Opera GX, Vivaldi, Zen, Waterfox, LibreWolf, Floorp, Yandex, Pale Moon, SeaMonkey, Tor Browser and Internet Explorer are all covered, and so is the next one you install. Browsers built into other apps are covered too.
The screen AI still sees it. A browser that routes its own traffic, like Opera with its built-in VPN or Tor Browser, can carry it past the network filter. It can't get past on-screen detection, which looks at what is on your screen however it got there. You can also block those browsers outright.
Not yet. Kellet runs on Windows today. Android and macOS land in Q4 2026, and iPhone and iPad in Q1 2027. Lifetime plans get each one the day it ships.
Yes, for the part a blocklist cannot do. Rules only work for sites somebody has already listed, so an AI vision model on your PC looks at the pictures themselves: as the browser downloads them, and on the screen as often as every few seconds, whatever app put them there. It blocks explicit nudity and sexual content from day one. Narrower categories, from suggestive poses and swimwear to lingerie, are yours to switch on, and you choose how sensitive it is. The model runs on your own processor rather than in a cloud service. No detector is perfect, so everything it acts on shows up in your activity for you to check.
No, unless you invite them. Your own activity log lives in your account for you to read. The only way another person sees any of it is if you add them as an accountability partner. They see your activity, you choose what, if anything, they can manage, and you can remove them, straight away or after a delay you choose.
No. Kellet is for adults who want a guardrail on their own devices.
On a shared Windows PC, Kellet watches every Windows user account on that computer, not only the one that installed it, unless you turn an account off on the device's page. It runs as a system service, so the browsing and app activity of everyone who signs in to that PC is recorded and reported to the account Kellet is enrolled to, and to any accountability partner on it. Get the agreement of the other people who use the computer before you install it. Kellet is meant for your own accountability, not for watching anyone without their agreement.
You pick a plan, or protection stops that day. The 14 days start when you add your first device, not when you sign up, and there is no extra window afterwards: blocking runs for the full 14 days and Kellet stops enforcing when the trial ends, until you subscribe. Your rules, your settings, your history and your clean streak stay in your account either way, so coming back later is not starting over.
Yes. We want you to genuinely love Kellet and if you don't, we'll give you your money back within 30 days of your purchase, no questions asked.
It shouldn't. And we make every reasonable attempt to ensure that it doesn't. Kellet is code-signed, appears in your installed programs and shows itself in the system tray. It never makes any attempt to hide itself because it is not spyware.
Fourteen days free, every layer on, no card needed.
