Asks why.
You open TikTok, Lumi opens its beak. Type your reason or say it out loud. "I'm bored" gets follow-up questions.
Linden · An AI that guards your blocked apps
Stopscrolling.
Lumi is an AI owl that argues with you before TikTok opens. You will lose that argument more often than you think.

Live · what it actually feels like
You don’tunlock the app.You earn it.
Open TikTok and Lumi steps in first. Tell it why. Sometimes you get your minutes. Sometimes you hear your own excuse out loud and close the phone yourself. That second one is the product.
- Lumi reads your reason, not a timer
- It remembers what you said yesterday
- Denied means denied. Arguing harder won't help

Five things Lumi does
One quiet AI.Five jobs.
02
Calls your bluff.
It remembers you said "just five minutes" six hours ago. And how that went.
03
Negotiates.
Good reason? You get minutes, on a timer you agree to. Weak reason? Counter-offer: do the thing you're avoiding first.
04
Refuses.
Some nights the answer is no. The block screen doesn't have an Ignore button, because Lumi isn't a screen. It's a no.
05
Lets go.
After a few weeks you argue less and open less. Lumi gets quieter as you get better. That's the exit plan.
A wall is somethingyou jump.
Every screen-time app you've deleted worked the same way: show a wall, hope you feel bad. You stopped feeling bad in about two weeks. A conversation doesn't wear off like that, because it isn't the same twice.
Every other blocker
Time’s up!
You’ve reached your daily limit for TikTok
OKIgnore limit for today
That second button is why it’s not working.

open tiktok, 5 min
It’s 1:14 AM. What are you hoping is in there?
...
There is no Ignore button. There’s an owl reading your answer.

What ten days does
The urge doesn’t die.It gets quiet.
Day 1
You argue with an owl. You think this is stupid. You open TikTok anyway, twice.
Day 4
You start losing arguments. Typing "I'm bored" for the ninth time does something to you.
Day 10
You catch yourself not reaching for the phone. Lumi didn't win. You did.

Achievements you can't buy
Stamps forboring victories.
No XP, no leagues, no streak anxiety. Just a stamp when you do the hard, unglamorous thing. They look good in a row.
First refusal.
You asked. Lumi said no. You survived.
Clean week.
7 days under your own limit.
Night owl down.
Zero scrolls past midnight, 5 nights.
Lost the argument.
Typed your reason, read it, closed the app yourself.
100 hours back.
That's two work weeks. Returned to sender.
Quiet phone.
A full day without opening a single blocked app.
People losingarguments daily.
I pay $8 a month to get insulted by an owl and my screen time is down 64%. Money well spent.
Deleted six blockers before this. This is the first one I couldn't outsmart at 1am.
It asked what I was avoiding. I said email. It made me do email. I hate it. Five stars.
My friend holds my override code. She has never once given it to me. Best decision of the year.
Week one I argued constantly. Week four I just... stopped opening TikTok. Weird feeling.
The sarcastic mode is genuinely funny, which is a problem, because I open it just to chat.
Lumi quoted my own excuse from Tuesday back to me. Cold. Effective.
First app where 'hardcore mode' means it. No ignore button, no mercy, no 3am Reels.
In Hardcore mode, even your best excuse won’t survive Lumi.
No override code. No "ignore for today". Your friend holds the key, and Lumi holds the door. You asked for this mode, remember that at 1am.
Why this exists
One person built thisbecause they had to.
I built Linden because I lost a year of my life to TikTok and none of the apps I tried fixed it. The thing that finally worked was being asked, out loud, why I was opening the app. So I made an AI that does that.

Doubts
Things you’realready wondering.
No. Screen-time apps are walls. You jump them. Linden is a conversation Lumi runs with you. It's harder to outsmart a question than a wall.

It takes one month to know if Lumi changes you.
