Rap lyrics written to your beat
Upload an instrumental, pick a flow for each part and hear it over the beat, then say what the track is about. The lyrics are written to that rhythm: one line per bar, the stresses on the strong steps.

Questions about the lyrics
Is it free, and why do I have to sign in?
It is free. Uploading a beat and trying the flows over it work without an account. Writing the lyrics needs a free sign-in with Telegram or Google: every take is a paid call to an AI model, and signing in keeps bots from using it up, so it can stay free for you. Signed-in visitors get a set number of takes an hour. A friend who signs up through your invite link gets bonus lyrics for when the hour runs out, and so do you, for your first 20 friends; after that only the friend gets them.
How does the AI rap lyrics generator fit the lines to my beat?
The beat is mapped first: its tempo, key, where each bar starts and where the intro, verses, hooks and outro are. Each part gets a flow, the rhythm that says where the syllables sit in the bar and which of them are stressed. You can play it over the beat and switch between five before a word is written. The lyrics are then written to that rhythm: one line per bar, the stresses on the strong steps. A line that misses is re-laid on its own stresses in the same flow, and the sheet shows each line's syllable count and whether its stresses land.
Does my beat leave the site? What does the AI get?
The audio never goes to the AI. The beat is read on our own server and deleted as soon as it has been read. The model (Claude, by Anthropic) gets numbers about it: tempo, key, the bar and section layout and the flow patterns, plus what you wrote about the track, its language, style and mood, and the lyrics so far when you ask for another take on a line. Those numbers are kept for two hours, then deleted.
Which languages can it write in?
Russian and English. Pick the language under the topic box; it does not have to match the language of this page. Syllables are counted exactly in Russian, one per vowel, and estimated in English.
Can I use my own flow?
Yes. For any part, press Record my flow and hum the rhythm over the beat, "na-na-na", in headphones. The page reads where each syllable lands and which ones you lean on, and the lyrics are written to that. The recording stays in your browser: only the rhythm is sent, never your voice.
Can I use the lyrics in my track?
They are written for you to use: rap them, rework them, put them in your track. Treat them as a draft. Click a line's last word for other rhymes, edit any line yourself, or ask for new takes in the same flow. It is AI-written text, so read it through before you release it and change whatever does not sound like you.
