How Sunbell was made (artificial intelligence)
Sunbell was made by Sunridge Labs LLC with the help of artificial intelligence (AI) tools. We used AI to help write the code, the phrases, and the texts of the App (including these documents), and to create the original sounds and images. We chose, tested, and edited the results before including them.
The Bible verses are not written by AI: they are copied word for word from the public-domain translations listed below. The sleep estimates are calculated on your phone by the App's own rules; no AI service receives your data.
Bible verses (public domain)
Spanish: Reina-Valera 1909, public domain. Spelling was modernized (for example "á" → "a", "fué" → "fue") and psalm titles were removed; the words were not changed.
English: King James Version (1769), public domain in the United States.
Texts were taken from the bible_databases project by Scrollmapper (https://github.com/scrollmapper/bible_databases), whose compilation is offered under the MIT License.
Recorded sounds (CC0, public domain)
These recordings come from BigSoundBank.com by Joseph Sardin, released under CC0 1.0 (public domain dedication). Credit is not required but is given with thanks. They were edited (trimmed, looped, and leveled) for the App.
