Kosher AI for Jewish Families
Tznius-first AI with GHOST intent filtering, zmanim, Sefaria sources, and family-safe SMS, web, and mobile.
If you searched for kosher AI, Jewish AI assistant, or tznius-safe chatbot, you are not alone. Jewish families want the productivity of modern AI without compromising halachic values, shalom bayis, or the standards they teach at home.
KosherChat is built for exactly that — not as a thin filter pasted onto someone else's model, but as a safety-first assistant designed from the ground up for Jewish life.
What "kosher AI" actually means
Most AI products treat "safety" as a checkbox: block a list of bad words, add a disclaimer, ship. That fails in two ways familiar to observant households:
- Surface filters are easy to bypass. Kids and adversaries rephrase requests; keyword lists miss context.
- Over-blocking ruins normal life. Strict regex filters refuse legitimate questions about health, grief, marriage, or current events.
Kosher AI needs a third path: strict on content, generous on real life. KosherChat hard-blocks sexual content, profanity, graphic violence, drugs, and harassment — then helps with zmanim, parsha, work, school, sports, recipes, and everyday tasks.
Built for Jewish daily rhythm
KosherChat is not a posek. It finds sources on Sefaria, links relevant passages, and always ends with: ask your rav. That boundary matters for families who want Torah help without accidental halachic authority.
What it does handle well:
- Zmanim and calendar — candle lighting, Havdalah, Yom Tov, local times
- Source hunting — Gemara refs, Shulchan Aruch pointers, Sefaria links
- Reminders and tasks — Shabbos prep, appointments, grocery lists via SMS
- One standard everywhere — same guardrails on SMS, web, iOS, and desktop Tether
Why intent-layer filtering matters for Jewish families
KosherChat uses GHOST — Generative Harm Observation via Subspace Trajectories — to filter at the intent layer, not just surface text. Instead of asking "does this sentence contain a bad word?", GHOST asks "what is this conversation actually steering the model toward?"
That architectural choice matters when:
- A teen tests boundaries with clever phrasing
- A multi-turn chat slowly escalates toward inappropriate content
- Someone frames a harmful request as "hypothetical" or "for homework"

SMS-first for the whole mishpacha
Many Jewish families prefer texting — on the go, during carpool, without opening another app. KosherChat works as a personal sidekick by SMS with the same clean filter as the web app.
Parents can also use custom skills to shape tone, vocabulary, and boundaries for each child — short answers for homework help, no slang, reminders to ask a parent before acting on advice.
