Guess which decade your lyric actually belongs in.
Paste a verse and the detector tags the signature words, line lengths, and rhyme habits that point to a 60s soul lyric, an 80s stadium hook, a 90s alt mumble, a 00s emo diary, a 10s festival chant, or a conversational modern song. It draws the distribution across all six. Free, runs entirely in your browser.
Your lyric
Paste a verse or chorus, one line per row. Six to twelve lines gives the cleanest read.
Heuristic guess, not a verdict. It counts signature words and habits — a lyric can lean on two eras at once.
Era report
Distribution across six decades. The tallest bar is the best guess.
What the detector looks for
A lyric reads like a decade for more than the words. Four signals are scored and mixed into the final distribution.
Signature word banks
Each decade has a vocabulary it leans on. “Groovy” and “flower” pull toward the 60s. “Squad” and “lit” pull toward the 10s. The detector counts how many of each bank show up in your verse.
Line-length profile
Stadium pop writes short, punchy lines. 60s folk and 90s alternative let lines breathe longer. The average words-per-line adds a small nudge toward the decades that usually write that shape.
Rhyme density
10s festival choruses and 80s hooks rhyme almost every line. 90s slacker verses and modern conversational songs let many lines end on a free beat. Density gives a second nudge.
Theme words
Recurring content words — “cigarette,” “rally,” “basement,” “rooftop” — carry era texture on their own. The detector lists the strongest ones in the reasons so you can hear the bias yourself.
Era tells at a glance
Same job — four lines of verse — written six different ways. The vocabulary and the line feel give the era away before you name the song.
| Era | Signature words | Line feel |
|---|---|---|
| 60s-70s | groovy, honey, tambourine, morning dew, freedom | Long, melodic lines that hold a vowel — soul and folk breath |
| 80s | neon, power, tonight, electric, working | Short, declarative lines built for a big chorus |
| 90s | faded, gray, whatever, numb, basement | Slacker mumble — unrhymed, dry, half-spoken |
| 00s | shattered, scars, eyeliner, parking lot, diary | Raw diary lines, internal, a little overwrought |
| 10s | hands up, bass, vibe, lit, festival | Chant-like, repetitive, built for a crowd to shout |
| Now | kitchen, radiator, grocery, quiet, commute | Plain, conversational lines in small, ordinary scenes |
Most modern hits borrow from three or four of these at once. The detector shows the blend as a distribution, not a single stamped decade.
How to use it
Ten seconds, no account, no upload — your lyric never leaves the page.
- Paste a verse or chorus, one line per row
- Hit Detect the era
- Read the distribution, then the highlighted evidence lines — those are the words pulling the guess where it lands
What this detector can’t do
It guesses by vocabulary and habits, not by sound. A 2024 song that deliberately mimics 1966 soul will read as 60s, because it should. It can’t hear the production, the drum sound, or the melody — those carry half the era. And a genre-blending track will land as a blend; a tall bar is a nudge, not a verdict.
Use it to check whether your verse accidentally sounds like another decade, or whether it has no era personality at all. If the guess feels wrong, trust your ear — the word banks live in the page source and you can argue with them.
About this tool
Built by Alex, the one-person operation behind FreeLyricsAI. I kept catching my own drafts leaning on whatever decade I was that week — a verse full of “whatever” one day, a verse full of “hands up” the next — and I wanted to see the bias on paper instead of guessing. This detector is that habit made visible.
It runs entirely in your browser so the page stays a writing tool, not another thing that watches you. The six word banks are right in the source — steal them, add words I missed, and tell me where the guess went wrong.
