You build the app.
We make it viral.
Growing an app today means feeding social media every single day. Hookstr makes the content for you — everything below was generated from one link, ready for you to post.
real, unedited output — each made from one link
One link in
App Store, Google Play, your website, or a sentence — we pull the name, copy and screenshots automatically.
Post-ready out
Vertical 9:16, captions burned in, hook first. No editor, no agency, no brief to write.
Endless takes
Don't like the angle? Regenerate. New hook, new creator, new vibe — until it stops the thumb.
Link in. Content out. Three steps.
Add your product
Paste an App Store, Google Play, or website link — or describe it in a sentence. We pull the details automatically.
Pick a format
Slide carousel or AI UGC video — standard or premium. Credit cost shown up front, always.
Post & get users
Download polished vertical content for TikTok, Reels and Shorts. Post it everywhere and turn views into installs.
Everything you need to get discovered.
Slide carousels
Value-first carousels that hook on slide one and pivot to your app — cohesive AI imagery, bold knockout captions, ready for the For You page.
AI UGC video
Pick a built-in creator, upload your own, or auto-generate one — with voiceover, b-roll and captions.
Seconds, not days
Skip the editor and the agency. Post-ready before your coffee's cold.
No keys, no setup
We handle the AI plumbing. One subscription, credits, done.
Endless variations
Tweak the angle and regenerate as many takes as you want — never post the same thing twice.
From a store page no one sees to a hook no one scrolls past.
The clip on the right is real Hookstr output — the difference is a hook engineered for the first three seconds.
Real output. Zero editing.

Questions, answered.
Hookstr is a viral hook generator for app & SaaS builders. The name says it — a “hook” is the scroll-stopping first few seconds that make someone stop and watch. Paste your App Store or Google Play link (or just describe your product) and Hookstr creates the hook content that gets it discovered: TikTok/Instagram slide carousels and short AI UGC videos, ready to post.
Either a TikTok/Instagram slide carousel or a short AI UGC promo video — captions, voiceover and b-roll included, sized vertical and ready to post. Every piece is built around a strong hook so it stops the scroll.
An App Store link, a Google Play link, or just a sentence describing your product. We pull the name, description and screenshots automatically when you paste a store link.
Each generation costs credits — slides 15 (standard) or 25 (high quality), videos 80 (standard) or 120 (lifelike). Subscriptions include a monthly credit allowance that resets each cycle; one-time top-up packs never expire.
You're never charged for content you don't receive — failed jobs automatically refund their credits to your balance.
Everything is composed vertical for TikTok, Instagram Reels and YouTube Shorts — the formats that get apps discovered fastest.
