Write lyrics that hit.
InnerHook is a lyrics editor for songwriters. The whole song on one page, syllables counted on every line, rhymes and synonyms one click away, and an AI that helps when you ask — without ever touching your song's structure.
Keep a daily writing habit, write with friends live, hear it sung, and take it to the stage.
The numbers in the margin are syllables. Of course they are.
Dana left her spare key on the fridge
under a magnet from Tallinn
I kept it there for seven months
turns out she got new locks in May
Call it a habit, call it a phase
I still set out two cups anyway
Select a word and the bubble gives you two buttons: Synonyms and Rhymes. Click one of the words and it's in the line, with the line's new syllable count. No tab to another site, no losing the thread.

to buy Lorraine a ring she won't wear

This demo has a few word lists built in. The app looks up any word.
A song is one document. Write, and press Enter twice when the stanza ends: you're in a new section. Sections label themselves — Verse 1, Chorus 1, Verse 2 — and the chip in the margin changes the type.
Got a whole lyric somewhere else? Paste it. It splits into sections on the blank lines, and [Chorus] style headers set the types.
A drawer full of them? Import .txt, .md and .docx files, read right in your browser: each file a song (or a song per heading), split into sections. A stanza that doesn't say what it is comes in as a Part, and Detect structure sorts the Parts into verses and choruses.
Type here. Enter twice for a new section, click a chip to change its type.
Today's pages
A few minutes of unfiltered writing a day. No sections, no syllables, no AI — just the page and whatever is in you today. Pick 5, 10 or 15 minutes, take the day's prompt (an everyday thing and a sense to write it through) or skip it, and keep the pen moving.
There's no ticking clock. The page slowly gets lighter and a thin line fills along the bottom. When the time is up, nothing stops you. Turn on No backspace to quit fixing as you go.
Today · sound
the last bus
What do you hear? Near and far, loud and barely there.
The doors fold open with a sigh like my dad getting off the couch.
Somebody's phone plays half a song and stops.
The driver says last stop to nobody, twice, like he's trying it out.
Brakes, coins, the hum of the heater under my seat.
Time. Keep going if it's flowing.
A made-up morning. In the app the page is all yours: no clock, no numbers, no sound.
Co-writing
Share a song and write in it at the same time, from anywhere. Every co-writer's caret shows in their colour with their name on it. Leave a comment on a line and @mention someone to let them know (by email, if they get comment emails). Undo only takes back your own changes, never your co-writer's.

“phase”
Mia @Joe is phase too soft? Maybe “call it a phase” stays.
Joe Keep it. It's what she'd say.
Share “Spare Key”
Line numbers on the left, syllables on the right, updating as you type. It counts English, and Finnish with its own rules for long vowels and diphthongs. So you see at a glance which line won't fit the melody, before the band does.
Line 3 is the one you'll trip over on stage. Now you know before rehearsal.
Line 1 is the tune:
Tell me I can keep the key
Type your rewrite, and the count tells you when it lands on 7.
Select lines and ask: Improve, Fix grammar, Make shorter or longer, Change tone, Translate — or type anything. The suggestion shows up as a diff right on your page. Accept, Discard, Insert below or Try again. Same number of lines in, same number out. It never rearranges your sections.
Call it a habit, call it a phase
I still set out two cups anyway
and than I end up pouring yours in the sink
because it's cold and you are not here
Scripted demo, same buttons. The real thing writes fresh lines every time.
Space on an empty line
Continue writing, write a verse or a chorus, or brainstorm — with the whole song as context.

Next to the AI button
Rhymes and synonyms, one click from any word.
No AI needed. Select a word, pick one, keep writing.
Hear it sung · Record an idea
Hear it sung sends the whole song, a section or a 30-second preview to AI (Eleven Music) and brings it back sung. You set the style: genre, mood, tempo, key, the singer, the sound. You see the length and its credits before it starts, and a take that fails costs nothing. The song's owner and anyone who can edit it can have it sung, with their own credits. Takes stay with the song: everyone who can open it can play and download them.

Chorus 1 · Folk · 96 BPM
Silent here: no voice in this demo. Prices on the pricing page.
Or sing it yourself. Record an idea on any section: the melody in your head, a hum, a demo take. With the song's tempo you get a bar counted in and, if you like, the click while you sing (headphones keep it out of the take). Up to three minutes, kept with the song. The owner, editors and commenters can record. Your own recordings use no credits.

Everyone who can open the song can hear and download your recordings.
Describe an artist or a project once: the style, the language, genres, themes, favourite imagery, the words it would never use. Pick some of your own songs as examples. From then on the AI drafts in that voice. It's built from your material and never imitates named real artists.
Still in last night's shirt at the gas station
my cousin's bouquet on the passenger seat
Mom sent me off with a plate of cake
and said call when you get there, not text
Three hours home and I'm already late
for a life I don't live in this state

Setlists · Stage
Put songs in order for a gig or a rehearsal. Drag them around, add what you'll say between songs, and a break for Set 2. Each song's length comes from a sung take or its tempo, so you know whether the set fits the slot. Print it for the floor.
Then press Stage: one song at a time, the words as big as the screen allows, the tempo and key on top, the next song at the bottom.
Spare Key
Verse 1
Dana left her spare key on the fridge
under a magnet from Tallinn
I kept it there for seven months
turns out she got new locks in May
A made-up gig. “≈”: estimated from the song's tempo; 3:12 from a sung take.
Every section has an A, a B and a Scratch version. Reimagine a section to get a fresh take on it. Version history keeps the song's past, ready to restore — and undo covers everything, AI edits included.
Nothing you wrote at 2 a.m. is ever really gone. Which may or may not be a good thing.

A private workspace.
Every account is its own workspace. Your songs, versions and artist profiles are yours alone, until you share a song with co-writers or turn on its public link: then only that song. Your daily pages are never shared.
Not training data.
Your lyrics are not used to train AI models. The half-finished ones included.
Questions
InnerHook is a web app for writing song lyrics. A song is one page split into sections (Verse, Chorus, Bridge…), every line shows its syllable count, and each section can keep three versions. Writing tools that use AI are there when you want a nudge, and you can write together with others live. More on “What is InnerHook?”
People who write lyrics: songwriters and lyricists, bands, writers who write for other artists, and teams who write together. It counts syllables for lyrics in English and Finnish. More on “Who is it for?”
InnerHook is for words. It is not a tool for composing music or chords, not a DAW or a recording studio, and not a machine for turning out finished songs in bulk. More on “Who is it not for?”
A notes app or a document editor sees text. InnerHook sees a song: sections with labels, a syllable count on every line, versions of each section and the song's tempo and key, and co-writers work in that same structure live. More on “How is it different from a notes app or Google Docs?”
No, unless you ask it to. InnerHook is a writing app first: the editor, the syllable counts, versions, Today's pages, setlists and co-writing use no AI at all. The AI tools are there for a nudge, and you decide what to keep. More on “Does AI write my songs?”
You do. You own what you write in InnerHook: your lyrics, notes, artist profiles, daily pages and comments. InnerHook claims no ownership of them. More on “Who owns the lyrics?”
No. InnerHook does not use your lyrics to train AI models, and its AI provider, Anthropic, does not use the content sent through its API to train its models. More on “Is my writing used to train AI?”
InnerHook is in closed beta: you need an invite. Join the waitlist on innerhook.com, or get invited to a song by someone who already writes in InnerHook. More on “How do I get access?”
