Decide it once, while you’re steady.
Block distracting websites, apps, and explicit content on your Windows PC. Kellet lets you set what you want to block and makes it difficult to undo in the moment, which helps keep you focused.
Everything unlocked for 14 days. No card to start.
This page is blocked by Kellet per your rules. It was added on 14 July.
Kellet never says no. It says not yet.
Tightening a rule takes effect immediately. Loosening one waits out the delay you set in calmer waters.
You set the delay
You choose how long a loosening has to wait, and you can set a longer wait for uninstalling. Whatever you pick is the number, and you pick it while nothing is pulling at you.
You ask to be let through
Kellet doesn’t argue and doesn’t lecture. It takes the request, starts the clock on the delay you chose, and leaves the block exactly where it is until that clock runs out.
Twelve minutes later, the urge has passed
The urge is gone and the timer is still running. You cancel the request, or you forget you ever made it. Both count as the same win.
Every wall you built, you climbed.
You have probably already tried a blocker. Possibly several. Here is how each of them ended, and none of the reasons are that you didn’t mean it.
You paused it
Most blockers have an off switch, and the ones that do not have a session that ends. A blocker you can switch off is a suggestion with a nice interface.
You uninstalled it
Two clicks in Add or Remove Programs and the wall is gone, with nothing between the decision and the deletion.
You opened another browser
The extension guarded Chrome. Edge was already installed. So was the phone in your other hand.
You went around it
A hosts file, a VPN, an image search that the blocklist never had a name for. The list is always one step behind.
Not because you’re weak. Because the person who set the rule and the person at 1am are not the same person, and only one of them was holding the switch.
Three layers catch it. The fourth keeps you honest.
The first three run on the device, in that order, so nothing depends on one blocklist being complete or one browser being the one you opened.
Cut off before it loads
Known sites are stopped system-wide, not inside a single browser. Every app on the device is behind the same filter, including the ones you forgot were installed.
Reads the page, not just the address
An on-device check looks at what actually loaded, so a brand-new domain or an explicit result buried in an ordinary search gets caught the same way a known site would.
Sees what’s on the screen
On-device models flag explicit imagery by what is actually displayed, whatever app put it there. The models run on your machine rather than in a cloud service, and anything it gets wrong you can restore yourself.
Holds you to the first three
Turning a layer down, allowing a site, ending a schedule early, removing Kellet from the device: every one of them is a request with a timer on it. Uninstalling is something you schedule, not something you click.
You can see everything. Nobody else can.
Rules, schedules, and history for every Windows PC you own, in one place. It is the same dashboard whether you have one laptop or five machines in the house, and it is where the Android and macOS devices will appear when those builds land.
Overview · Kellet for Windows
There is nobody on the other end.
Most tools in this category work by telling on you. Kellet works by holding a door shut. That difference decides who gets to read your activity, and the answer is nobody but you.
Detection runs on the device
Screen and content checks run locally, on the machine in front of you, rather than in a cloud service that inspects what you are looking at. What they record goes to your own account so you can read it back.
No supervisor account
There is no parent, no admin, and no reviewer above you. Your activity lives in your own account, and by default it is the only place it exists.
A partner, only if you want one
Invite a spouse, sponsor, or friend and choose what they can see and do. They can hold your overrides or just be in your corner. You can remove them whenever you like, and they never pay a penny.
Kellet is built for devices you own. It is not a way to watch another adult, and we will not sell it as one: no covert install, no hidden mode, nothing that hides itself from the person using the device. That is not a compliance footnote, it is the difference between a commitment device and spyware.
What each platform can actually enforce.
A blocker that overpromises gets uninstalled the first time it doesn’t hold. So, plainly: Kellet runs on Windows today, and nowhere else yet. Android lands at the end of September 2026, macOS in Q4 2026, and iPhone and iPad in Q1 2027. If the device you care about isn’t Windows, it is not protected yet, and we would rather you knew that now than after you paid.
Windows
Live- Stops known sites before they load, in every browser and app
- Reads the page itself, so a site registered this morning is caught too
- Flags explicit images and video on screen, and hides the thumbnails
- Blocks apps, locks the device, and runs scheduled blackouts
- Uninstalling waits out the cool-down, like every other way out
Android
September 2026- Not out yet. Kellet does not run on Android until then
- At launch: network filter, content screening, app blocking, device lock
- Removal will wait out the same cool-down as everywhere else
- On-screen detection too, off until you switch it on
macOS
Q4 2026- Not out yet. A Mac is unprotected until it ships
- At launch: full parity with Windows, including screen detection
- Your plan and your rules carry over the day it lands
iPhone & iPad
Q1 2027- Not out yet. An iPhone is unprotected until it ships
- At launch: site filtering and schedules, within what iOS allows
- No on-screen detection: Apple does not permit it
- No uninstall cool-down, so it will hold less than the desktop app
Priced like infrastructure, not an app.
The tool people actually rely on in this category costs $198 a year and works by reporting what you did to somebody else. Kellet judges what is on the page, tells nobody, and costs about 40% less.
Blocks sites, page content, on-screen images, and apps Cool-downs on every way out, uninstall included Every Windows PC on your account Schedules, blackouts, and full history
Everything in Monthly $61 a year cheaper than paying monthly Accountability partners, if you want them One renewal to think about, not twelve
Everything in Annual Every future update included Android, macOS and iOS the day each one ships Nothing renews, ever
A week of grace, then it stops
Blocking keeps running for seven days after day 14, so nothing cuts out the moment the trial ends. After that Kellet stops enforcing until you pick a plan. Your rules, your history and your cool-down settings stay put, so subscribing later picks up where you left off.
Hand the override to someone you trust
Invite a spouse, sponsor, or friend, choose what they can see and do, and give them the say over your overrides. Included in your plan, and working today.
Partners never pay
If someone adds you as their accountability partner, your side of it costs nothing, forever.
The questions people actually ask.
Can I change a rule after I’ve set it?
So I can never uninstall it?
What happens when the 14 days are up?
Does anyone see what I look at?
It flagged a photo of my kids. Now what?
Will my antivirus complain about it?
Calmer water is one decision away.
Kellet blocks the distractions you choose and lets you stay accountable to yourself, or to someone you trust.
