Terms of Service

Last updated October 28, 2026

1. Who we are

lyricbook (lyricbook.ai, formerly LyricAI at lyricai.io, “the Service”, “we”, “us”) turns recordings into lyrics. You can reach us at support@lyricbook.ai. By creating an account or using the Service you agree to these terms.

2. The service

lyricbook turns songs into written lyrics. You can give it a Spotify song or album link, a link to a YouTube video, or an audio file from your device. Get lyrics transcribes the recording automatically and times every word and line; it can also translate the lyrics and detect the song’s chords. Look up lyrics online, for Spotify songs, looks for existing public lyrics in LRCLIB and then lyrics.ovh and shows them as published, without transcribing anything. Results are deleted from our servers 24 hours after they’re made; your browser keeps a copy unless you turn that off, and you can download anything you want to keep.

You can also use the Service from your own software through its API, with keys you make in your account. Everything sent with your keys counts as sent by you: it uses your account’s credits like songs sent from the site, and these terms apply to it. Keep your keys secret, and revoke any key that may have been exposed.

lyricbook is not affiliated with, endorsed by, or sponsored by Spotify, YouTube, LRCLIB, or lyrics.ovh. Links you submit point to those services, and your use of them is governed by their own terms.

3. Who can use it

You must be at least 13 years old to use lyricbook. If you’re under 18, or under the age of majority where you live, you need a parent’s or guardian’s permission to buy credits. The Service isn’t directed to children under 13.

4. What you send us

• Only submit links and upload files that you have the right to use this way. By uploading a file, you confirm that you own the recording or have permission from its rights holders to have it transcribed.
• You keep whatever rights you have in what you upload. You allow us to store and process it only to make your lyrics; uploaded files are deleted once they’ve been transcribed (see the Privacy Policy).
• Uploads must be audio files of up to 50 MB. Video files aren’t accepted.

5. Acceptable use

You agree to use the Service only for lawful purposes. You may not:

• Use the Service to infringe anyone’s intellectual property or other rights
• Upload recordings you don’t have the right to use, or content that is unlawful
• Publish or commercially redistribute generated lyrics or subtitles without the rights holders’ permission
• Attempt to reverse-engineer, overload, or abuse the Service
• Use automated tools to access the Service other than through the API, or get around the API’s limits

6. Credits, payments, and refunds

Credits are bought through Stripe, priced in US dollars, and used to process songs. One credit covers one minute of audio, rounded up per song. Translating a song uses 1 credit more, and its chords 1 credit more, whatever its length.

• Each person gets one free song, up to 10 minutes long, translation and chords included. Deleting an account and signing up again doesn’t give another one, and temporary email addresses don’t get one
• A song is priced on the length we measure when you send it and settled on the recording’s actual length once we process it: if it is a minute or more shorter, the difference goes back to your balance; if an uploaded file or video is longer, the extra minutes are used from your balance, or the song isn’t processed and you aren’t charged when your balance doesn’t cover them. A Spotify song never costs more than the price shown
• A signed-in account can check in once a day for 1 free credit, or 3 on every 7th day in a row. Days follow the time zone your device reports; after a change of time zone, the next check-in waits until 20 hours after the last one. Free credits have no cash value and can’t be refunded. We may change or end daily credits; credits already given stay in your balance
• Credits never expire
• Bought credits are non-refundable, except where the law requires otherwise (see section 7)
• Credits for songs that fail to process are returned automatically
• Every song sent with Get lyrics is transcribed and timed and uses credits by the minute, plus its translation and chords if you ask for them. Look up lyrics online doesn’t use credits
• A transcribed song we find is already sung in the language you asked to translate it into isn’t translated, and its translation credit is returned automatically
• If no chords can be found in a song, the chord credit it used is returned automatically
• Deleting a song doesn’t return the credits it used

Auto top-up. If you turn on auto top-up on your Account page and save a card, you authorise us to charge that card through Stripe, without asking each time, for the credit bundle you chose whenever a request leaves your balance below the amount you set, and for up to 3 bundles at once when a request needs more credits than you have. We charge at most 3 times in any 24 hours. Credits bought this way are bought credits under this section. You can turn auto top-up off at any time on your Account page; if a charge is declined, we turn it off.

7. Your right to cancel

If you live in the European Union or the United Kingdom, you can withdraw from a credit purchase within 14 days without giving a reason, and the unused credits from that purchase are refunded. Each song you submit is a service we start straight away at your request. When you submit a song, you ask us to begin immediately and acknowledge that you lose the right to withdraw for that song once it has been processed. To withdraw, email support@lyricbook.ai from your account’s address.

8. Lyrics and intellectual property

Song lyrics are protected by copyright and belong to their writers and publishers. lyricbook claims no ownership of any lyrics, transcriptions, or translations. The Service is provided for personal listening, study, and accessibility.

9. Copyright complaints

If you believe material processed or stored through lyricbook infringes your copyright, send a notice to our designated copyright agent at support@lyricbook.ai. The agent is registered with the US Copyright Office (registration DMCA-1082463); its full contact details are in the Office’s DMCA Designated Agent Directory. Under the US Digital Millennium Copyright Act (17 U.S.C. §512(c)(3)), your notice must include:

• Your physical or electronic signature
• The copyrighted work you believe is infringed
• The material you believe is infringing, with enough detail for us to find it (for example, the sheet’s LYRC reference)
• Your address, telephone number, and email address
• A statement that you believe in good faith that the use isn’t authorised by the copyright owner, its agent, or the law
• A statement that the notice is accurate and, under penalty of perjury, that you are authorised to act for the copyright owner

If your material was removed and you believe that was a mistake, you can send a counter-notice with your signature, the material and where it appeared, a statement under penalty of perjury that it was removed by mistake or misidentification, and your name, address, phone number, and consent to the jurisdiction of the US federal district court for your address (17 U.S.C. §512(g)(3)). We terminate the accounts of people who repeatedly infringe others’ copyrights.

10. Accuracy

Transcriptions and translations are produced automatically and may contain mistakes. Don’t rely on them where accuracy matters without checking them.

11. Your data

Audio fetched for a link exists only in a temporary processing container. Files you upload are stored privately and deleted once transcribed, or within 4 hours if never submitted. Our processing provider keeps an encrypted copy of the audio sent for transcription for up to 7 days, then deletes it automatically. Lyric results are deleted from our servers 24 hours after they’re made; copies saved in your browser stay there until you delete them. The Privacy Policy explains what we keep and why.

12. Disclaimers and liability

To the extent the law allows, the Service is provided “as is” without warranties of any kind, we aren’t liable for indirect, incidental, or consequential damages, and our total liability is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability that can’t be limited by law, such as liability for fraud or for death or personal injury caused by negligence, or any rights you have as a consumer that can’t be waived.

13. Ending your account

You can delete your account at any time from your Account page. Unused credits are forfeited when the account is deleted. We may suspend or close accounts that break these terms.

14. Disputes and governing law

If something goes wrong, please contact us first so we can try to put it right. These terms are governed by the laws of the State of California, United States, without regard to its conflict-of-law rules, and disputes will be heard by the state or federal courts located in California. If you are a consumer living in the European Union or the United Kingdom, you also keep the protection of the mandatory laws of your country and may bring a claim in the courts where you live.

15. Changes

We may update these terms. We’ll tell you about significant changes by email or with a notice on the Service before they take effect.
