Jewish homes have always built for Shabbat — the timer, the eruv, the hotplate. Mendel stands in that lineage: infrastructure in service of the day, never instead of it.
The story
Mendel started with a simple observation: the hardest hours of the Jewish week to get help with are exactly the hours when no one will touch a phone. A grandmother alone across town. A houseful of guests and a door that needs answering. A first-time Shabbat keeper staring down a Friday afternoon of timers and lists.
Mendel is a small company — a founder building for his own community, with rabbinic guidance shaping the product from the first sketch. Every design decision started with the same question: what would make this easier to keep, not easier to skip?
Everything is decided before Shabbat. During Shabbat, nothing is asked of you — and nothing is done that couldn't be.
Your instructions lock in before Shabbat begins. During Shabbat, Mendel accepts no commands and makes no new decisions — it can only follow what was already set, the way a Shabbos clock always has.
No buying, selling, paying, or dealmaking of any kind, in your name or anyone's. Whatever wasn't settled before Shabbat waits for Havdalah.
Candle-lighting and Shabbat's end come from the published calendar times for your exact location — confirmed with you during setup, not guessed.
If Mendel ever can't tell what time it is, it treats the moment as Shabbat and sits still. A broken clock never breaks Shabbat.
A real emergency always escalates to the people you chose — and our Premium plan will add licensed 24/7 professional monitoring. That isn't an exception to the design; it's the oldest rule in it.
Nothing is shown to you during Shabbat. When it ends, you get a short, quiet note about what happened — usually: “all quiet.”
Mendel was designed with rabbinic guidance, and we keep asking questions as we build. But it doesn't answer halachic questions and never will — whether it belongs in your home is between you and your rav. If you bring your rav questions about how Mendel works, we'll gladly provide every technical detail.
Our rule on rabbinic quotes
You'll notice no rabbi is quoted on this site. That's deliberate: Mendel quotes rulings verbatim and with permission, or not at all. When our reviewing rav provides written wording, it will live right here — word for word.
Everything else — the timers, the codes, the recap — exists so that for twenty-five hours, you don't have to think about any of it.
