The rules for using blüp, in plain words.
Last updated 9 November 2026. Using blüp means agreeing to these terms.
You are responsible for what happens under your account and for keeping your password and recovery code safe. If you lose both and gave no email address, the account cannot be recovered — that is the trade-off for being able to sign up without one.
One person, one account. Don't impersonate somebody else in your username, avatar or bio.
You keep every right to the patterns you write. blüp does not claim ownership of your work and will not sell it, license it, or train anything on it.
What blüp needs is narrow and only for running the site: permission to store your track and show it back to you, and — only if you press Share to community — to display it publicly alongside your username, and to let other people open and remix it. That is what sharing means, and it is why it is a deliberate button rather than the default.
Unshare a track and that permission ends for the future. Copies other people already made are theirs, in the same way that is true anywhere else.
By sharing, you confirm the track is yours to share.
blüp plays sample libraries it did not create, and their terms are not all the same. A pattern you write is yours; the recordings it triggers are not automatically yours to sell.
Some libraries here are clearly licensed. Others — including Dirt-Samples, the long-standing TidalCycles library — declare no licence at all. They are distributed for making music with, which is not the same as a grant of rights. The full list and what is known about each is on the credits page.
So: making music, learning, playing, and sharing here is what blüp is for. If you are going to release something commercially, or if a track leans on a recognisable break, clear the samples yourself. blüp cannot grant rights it does not hold, and does not pretend to.
The same goes the other way: don't upload or paste in material you have no right to use.
Ask AI sends your prompt and the current track's code to Anthropic's API and writes the reply back into the editor. Three edits per track, unless your account is set otherwise.
It produces Strudel patterns and nothing else, and its output is checked before it is accepted. It can still be wrong, break your track, or misunderstand you — check what it gives you before you keep it. blüp is not responsible for what the model writes.
Don't put anything confidential into the prompt. See the privacy page.
blüp is free and runs on one modest server. Requests are rate-limited, and the AI editor is capped per track. Don't try to route around those limits, script the site, or scrape it.
No guarantee is made about storage limits, uptime, or how long the service will exist. If blüp is ever going to shut down, reasonable notice will be given so you can export your work — and you can export it at any time, as audio, MIDI or code.
Shared tracks and public profiles can be moderated. A track can be unshared, and an account can be suspended, when these rules are broken.
blüp is provided "as is", with no warranty of any kind, express or implied, including fitness for a particular purpose. It might lose your work, go down, or change. Export anything you care about.
To the fullest extent the law allows, blüp and its operator are not liable for any indirect or consequential loss, or for lost work, arising from using the service. Nothing here limits liability that cannot legally be limited.
You can stop using blüp at any time and ask for your account to be deleted: hello@blupit.app.
Accounts that break these rules can be suspended or removed, generally with an explanation unless the breach is serious.
These terms may change; the date at the top says when they last did, and continuing to use blüp means accepting the current version.
blüp is operated from the United States and these terms are governed by the laws of the State of Texas, without regard to conflict-of-law rules. If any part of this is unenforceable, the rest still stands.
blüp is built on Strudel, which is free software under the AGPL-3.0 licence. Details and the other credits are on the credits page.
