Bring your own sources, and let Ultra find more
Some questions reach beyond the Sefaria library: a Hindu festival set beside Hanukkah, a Christian commentary on a verse, a scholarly article you are reading. SeferAI can now read web pages along with the Jewish texts it searches.
Paste a link into your question
Put the address of a page in your question, and SeferAI reads that page alongside the passages it finds in the Sefaria library. The answer cites the page next to the Jewish sources, so you can follow every claim back to where it came from.
- [Premium](https://seferai.org/premium) reads links to Sefaria and to a set of reviewed scholarly and primary-text websites.
- [Ultra](https://seferai.org/news/ultra/) reads any public web page.
- On the free plan, links are not read; the question is still answered from the Sefaria library.
Ask for more from the same site
Linked one chapter and want the ones around it? Say so ("and the related chapters on this site"), and SeferAI picks up to three pages from that site that fit your question, reads them and cites them too.
Ultra: Find more sources
[Ultra](https://seferai.org/news/ultra/) members get a new switch under the question box: Find more sources. Turn it on and SeferAI searches a set of reviewed scholarly and primary-text websites for pages that fit your question, such as translations of other traditions' scriptures or reference articles. Up to five pages are read and cited, each marked as found by search. The switch is off by default, works on the web for now, and allows ten searches a day.
Every page is checked before it is read
A web page can contain text written to mislead an AI. Before SeferAI uses a page, it removes hidden text and reader comments, checks the rest for instructions aimed at AI systems and sets aside any page that has them, and keeps the page's words apart from its own instructions. Answers link only to the pages you gave or that were found for you, and to Sefaria and SeferAI.
Follow-ups keep their settings
A follow-up question now keeps the collections, style and answer language of the question it follows, and the follow-up box shows which settings it is using. Answers that contain tables now show them as tables.
