One app instead of three

A kosher scanner, a zmanim app and a chatbot you can’t check. KosherGPT does all three, in English, Hebrew and Russian.

  • Answers with sources. Numbered links to the Mishneh Torah, the Shulchan Arukh and more.
  • Zmanim and Shabbat reminders. For your city, with a reminder before candle lighting.
  • Shabbat mode. From candle lighting to Havdalah nothing is sent to the network.
  • Barcode scanner. Point the camera at a product in the store.

Kosher lists: rolling out with kashrut departments

Scan in the store. See whose list it’s on.

The scanner never says “kosher” on its own. It shows which organization lists the product, in which edition and with which markings. When it doesn’t know, it says so.

Example products, sample data.

Shabbat, on time

Zmanim for your city or one you pick. A reminder 30 minutes or 2 hours before candle lighting, and one at Havdalah. On Shabbat the app works from saved data and sends nothing.

Ask me about Halacha, Kashrut or the app.
May one eat chicken with milk?
KosherGPT

No. Eating poultry with milk is forbidden by rabbinic decree, though not by the Torah.

Unlike meat with milk, cooking poultry with milk or benefiting from it is not forbidden; only eating it is.

How long after meat before dairy?
KosherGPT

The common practice is to wait six hours.

Some communities keep shorter customs, recorded by the Rema. Ask your rabbi which custom your family follows.

Does the app work on Shabbat?
KosherGPT

From candle lighting to Havdalah the app works from saved data and sends nothing to the network.

Do you keep a kosher product list?

We link it to barcodes for free and show it in the scanner, with your organization named as the source. Nothing goes live before you check it.
