02 · The pitch

What is a Lion Gatekeeper?

A Lion Gatekeeper is a short, silent video of a lion that takes over the screen once you've scrolled past your limit. Install the Pet Gatekeeper extension, and when a feed keeps you too long, a lion walks into the tab and holds its ground right in your way — no counter, no nagging popup, just a very regal cat that isn't leaving until the cool-down ends.

03 · Why it works

Why a lion gatekeeper works so well

The feed is built to keep you on autopilot. A lion walking into view is the kind of thing your brain can't ignore — a Lion Gatekeeper borrows that instinct to break the scroll, no willpower speech required.

It also has authority. A Lion Gatekeeper doesn't negotiate or lecture; it takes the throne in the middle of your timeline and waits, with the patience of an animal that naps most of the day, until you close the tab.

04 · Where it earns its keep

Where a Lion Gatekeeper fits

Deep-work guard duty.

Point the Pet Gatekeeper extension at X and the usual rabbit holes, and a Lion Gatekeeper shows up the moment you drift — a much firmer hint than a gray timer.

Late-night wind-down.

It's completely silent, so a Lion Gatekeeper at 1 a.m. won't wake anyone — it just plants a calm, sleepy lion between you and another hour of Reddit.

For the lion person.

Team mascot, a Leo birthday, or a lifelong big-cat fan — a Lion Gatekeeper is a gift that's funny and genuinely useful.

Make it yours.

Swap the lion for your own cat, dog, or rabbit anytime — the Pet Gatekeeper extension treats every animal the same.

05 · How it works

How to make a lion gatekeeper

  1. 01

    Bring a few lion photos

    Upload 1–4 clear images of a lion — a zoo shot or a sharp reference photo showing the whole body, without heavy shadows.

  2. 02

    Approve the pose

    Your photos become two green-screen poses. Keep the ones you like, or regenerate until the lion looks right.

  3. 03

    Generate two clips

    An intro and a loop render out, then you fine-tune the green-screen removal right in your browser.

  4. 04

    Redeem in the extension

    You get an 8-character code. Paste it into the Pet Gatekeeper extension or desktop app, and your Lion Gatekeeper guards the next feed that tries to keep you.

06 · Tips

Tips for a great lion gatekeeper

  • Use a sharp, high-resolution lion photo — the more detail in the mane, the better the finished Lion Gatekeeper looks.
  • Pick a shot where the whole lion is in frame, mane to tail tuft, rather than a tight face close-up.
  • A simple background (dry grass, sand, rock) works better than a busy scene with other animals or heavy shadows.
  • Not happy with the first pose? Regenerate before moving on — it's much easier to fix the pose than the finished video.
