Borrow a hook shape, not a whole song. Steal the rhythm, write the words.
Pick a mood and a style. The vault opens a grid of ready-made hook phrases, each tagged with its syllable rhythm — the short-short-long shape the ear latches onto. Copy the one that fits. Free, runs in your browser.
Open the vault
Mood drives the shelf; style ranks the hooks that fit your sound first.
The rhythm tag shows syllables per word, like 1-1-3. Match it to your melody's pulse.
Hook grid
Red border = matches your style. Copy any phrase, then swap the words for yours.
How a hook is built
A great hook is a rhythm first, a meaning second. The vault shows you the rhythm so you can build your own words on the same pulse.
Short-short-long
The ear loves a three-beat shape: two quick words, then one that lands. “Hands up to the sky” is 1-1-1-1, but “I still reach for you” is 1-1-1-1 too — the rhythm tag lets you match the shape to your melody.
One image, said tight
Every hook here is one idea, in as few words as it takes. No side sentences. If your chorus needs more, the verse is where it lives.
Mood before genre
A hook carries a feeling before it carries a style. Start from the mood you want the listener to feel, then let style pick which ones fit your sound.
Steal the shape, rewrite the words
Do not copy the line. Copy its pulse and its one idea, then write your own specifics on top. That is how hooks become yours without being anyone else's.
Read the rhythm tag
Each number is the syllable count of one word, in order. The shape is what you sing.
| Tag | Shape | Feels like |
|---|---|---|
1-1-1-1 | Four short words, evenly stressed | Punchy, chantable, pop and EDM backbone |
1-1-2 | Two quick, one lands | Classic earworm close – the long word sings |
2-1-1-2 | Wider, more narrative | Country and rock – room to tell a little story |
1-3 | One short, one long – sparse | Atmospheric, risky – works when the melody carries it |
When you rewrite a hook, keep the tag. Change the words but hold the rhythm, and your new line will sit in the pocket the same way.

- Copy a rhythm you like, then swap the words for your own specifics. Shuffle again for a fresh shelf
What this vault can't do
These are shapes, not guarantees. A hook that reads well on the page can refuse to sing, and a plain phrase can become an earworm with the right melody. The vault does not write your chorus for you – it hands you a pulse to build on.
If nothing fits, trust your own instinct more than the bank. The tags are a starting point, not a rule. Every great hook was someone’s small idea, turned up loud.
About this tool
Built by Alex, the one-person operation behind FreeLyricsAI. I kept noticing that my choruses failed not because the words were bad, but because the rhythm was vague. So I started collecting the short, punchy shapes real hits use, and this vault is that collection, sorted by feeling.
It runs entirely in your browser because I would rather it stay a writing tool than become another thing that watches you. The phrase bank lives in the page source – steal it, argue with it, and send me the hooks you wrote that belong in here.
