You can hear a rhyme scheme and you can feel one, but you cannot fix one until you can see it. This annotator labels every line with its rhyme letter, builds the scheme string (AABB, ABAB, ABABCC…), and shows the ending word it used for the match — so broken patterns, accidental monorhyme and lazy repeats become visible at a glance.
The matching uses ending-sound keys, so “on / knew / true / do” reads as AAAA, and a verse that drifts off-pattern shows exactly where it drifts.
Rhyme-Scheme Annotator
How to use it
- Paste your section with one line per row — a verse or chorus at a time works best.
- Press Annotate scheme. Each line gets a letter for its ending sound.
- Read the scheme line: AABB, ABAB, ABABCC, or something accidental.
- Fix the drift: either rewrite an off-pattern line, or change the scheme deliberately and keep it consistent.
Best use cases
- Diagnosing a chorus that “almost rhymes” and finding which line breaks it.
- Designing schemes on purpose: AABB for punchy pop, ABAB for story verses, monorhyme for hooks.
- Checking AI-drafted lyrics for accidental monorhyme across a whole verse.
- Teaching form — the scheme string is the fastest way to show a student their own pattern.
- Rhyme the vowel, not the spelling — the tool matches ending sounds, so “true / do / knew” count together.
- Change the scheme between sections on purpose (ABAB verse into AABB chorus) and the switch itself adds lift.
- Two lines sharing a letter several sections apart is a feature — that is a remote rhyme; make it exact.
What good looks like
A deliberate scheme looks regular on the page: the same letters sit next to each other, or alternate with discipline. What you want to avoid is accidental irregularity — five lines of ABAB, then one stray C that nobody intended. If the scheme string reads clean, the section will feel finished.
Frequently asked questions
How accurate is the sound matching?
It is a heuristic on ending sounds — reliable for most English lines, imperfect on slant rhymes, dialect and stacked multisyllabics. Where the tool and your ear disagree, believe your ear and treat the letter as a hint rather than a verdict.
Does it handle multisyllabic rhymes?
It matches final-sound keys, so “again / rain” works, and long words with the same ending collapse into one letter. Full stacked-rhyme analysis is beyond it — for dense rap schemes, check the last two syllables by ear as well.
Can I annotate a whole song?
Yes, but section by section gives cleaner schemes — verses and choruses usually run different patterns, and the interesting question is exactly how they differ. Annotate verse one, then chorus one, then compare the two strings.
Private?
Yes — everything runs locally in your browser. See the disclaimer.
What do the letters mean?
Every distinct ending sound gets a letter in order of first appearance: A for the first, B for the next new sound, and so on. AABB is two couplets; ABAB alternates; a stray letter that appears exactly once is usually a line that drifted off-plan.
