AI Hook Generator: Stop the Scroll in Under 2 Seconds

Anyone can write a good opening line for a single video. The difficulty appears when you're posting daily across three platforms and several accounts, because that's three hundred hooks a quarter, and hook quality is the first thing to collapse when volume goes up.

What usually happens is that a creator finds two or three formulas that work and runs them into the ground. Retention decays, the audience stops reacting to a pattern they've seen forty times, and the account plateaus without an obvious cause.

ShortFast writes the hook as the first line of every script, fresh for each topic, rather than repeating whichever one worked last month. You get variety without having to personally think of it.

When an automation writes its next episode, it starts from scratch: a new topic on the same theme, and with it a new hook. Across a series, your posting schedule becomes a steady stream of different openings without any extra work on your side.

This is the part that's genuinely hard to do manually. Writing a fresh, strong opening for every daily video is the first thing people stop doing when volume goes up. Because it happens automatically, new openings keep going out whether or not you feel like writing them.

Over time this compounds. Compare early retention across your episodes and you learn which kinds of opening work for your specific audience, rather than which openings work in general.

Two upgrades are on the way. A/B variations will give every variation of a video its own opening, so your normal posting schedule doubles as a test of which hooks hold your audience. Per-platform tuning will write the opening differently for TikTok, where fast completion wins, for Reels, where saves and sends count, and for Shorts, where viewers give a little more runway for a clearer promise.

Both are coming soon. Start your ShortFast trial from this page to get early access when they ship.

If you'd rather generate hooks by hand and write your own videos, the free hook generator does the same pattern-matching without an account. It runs in your browser, gives you twenty openings per topic, and explains the mechanism behind each one so you can learn the patterns rather than just copy the output.

The automated version exists for the case where you're producing at volume and can't hand-write an opening for every video. If you're posting once a week, the free tool is genuinely all you need.
