For songwriters who sing
From first line to finished song. You write. Estrofa checks, and helps you practise, record and master.
Rhymes, syllables and clichés, with the reason shown — never a rewrite you did not ask for.
- English and Spanish
Where the song gets lost
One song, a handful of apps, and none of them knows the others.
Words in one place, sound in another
Lyrics in a notes app, a rhyming site in the browser, the melody in voice memos, the take in a DAW. Every switch costs the line you were holding.
Counting on your fingers
Does the second verse scan like the first? Does that line still rhyme? You check it by ear, again, every time you change a word.
Tools that write it for you
Many AI songwriting tools write the lines for you. Then it is no longer your song.
The path
One app, from the first line to a song you can send.
Estrofa follows a song the way you make it, and stays out of the way where you know better.
Write, or bring your lyrics
Write in Estrofa or import a text you already have. Rhymes, synonyms and phrases are a click away.
Check what you wrote
Syllables per line, stress, rhyme scheme, repetition and worn-out phrases — each finding with the reason it was raised.
Practise over your track
Load your backing track, put on headphones and sing it through with the lyrics in front of you, as often as you like.
Record the take
When it feels right, record your vocal over the track.
Master and export
Pick one of a few mastering profiles, adjust a handful of controls, and export the song.
The check shows its work
Every finding says what it saw, and how sure it is.
Facts and taste, kept apart
A syllable count or a rhyme can be checked, so it becomes a finding. Whether an image works is taste, so it stays a hint. Estrofa never calls your taste an error.
It says when it cannot tell
Some words can be counted two ways. Then Estrofa says so, instead of guessing and sounding sure.
Suggestions only when you ask
Want a way to fix a line? Switch suggestions on. Every suggestion is checked against the same rules before you see it. Off, Estrofa only checks.
- Finding — checked, with the reason
- Hint — taste, yours to decide
- Cannot tell — said out loud
Your words stay yours
Your lyrics are checked on your device.
Local by default
Checks run on your device. If you choose a cloud model for suggestions, Estrofa tells you what is sent.
Never trained on
Estrofa does not train any model on your lyrics, and does not copy anyone else's.
It remembers for you
Your songs, the lines you threw out, your themes: Estrofa keeps them in a notebook on your device, so it knows your voice and not someone else's.
In the studio
In a DAW session, the lyrics come with you.
A VST3 that follows the session
Open the finished lyrics in your DAW. They follow playback while you record with the DAW's own tools.
Small changes, right there
Change a word between takes without leaving the session. The writing and checking stay in the app, where they belong.
Founding songwriters
Help us shape Estrofa before anyone else.
We are looking for a few songwriters who sing their own songs, in English or Spanish, to write and record one song with an early build and tell us what gets in the way. Join the waitlist and tell us what you write — we will write to you.
FAQ
Questions songwriters ask
When can I use it?
Estrofa is in development. Everyone on the waitlist hears first when early access opens. We do not give a date we cannot keep.
Will it write lyrics for me?
No. Estrofa checks what you write and, only when you ask, suggests a fix that you can take or leave.
Does it work in Spanish?
Yes, English and Spanish, including Spanish metre: syllables counted the way poets count them, with sinalefa.
Which AI does it use?
Language rules on your device do the checking; no AI model is needed for that. For suggestions you can choose a cloud model, and Estrofa tells you before anything leaves your device.
Which devices?
We will confirm the devices before early access opens. The VST3 runs in your DAW.
What does it cost?
The price is not set yet. People on the waitlist hear it first.
What happens to my email address?
We use it only to tell you about Estrofa, and delete it when you ask.
Be among the first to write with Estrofa.
We write when early access opens and when the price is set. Nothing else.
