See the change before it goes public — real-time economic intelligence.

KlockIn Market
klock.opus-studio-eight.com

Grid clock — time as illuminated cubes.

Klock is a brutalist grid clock — instead of digits, the current time is rendered as four columns of illuminated cubes: hours, tens-of-minutes, minutes, and seconds. Each column lights its cubes from bottom up to indicate the value. No animations, no skeuomorphism, no fluff — just time as visible state. Single-page web app, Hebrew RTL, vanilla JS.

/03KOSHERWEB

Kosherweb

One platform, seven signed components — DNS, browser, classifier, search, vision, trust PKI, and the membership layer that holds them together. Not seven separate products: one religious-internet stack.

Kosher BrowserFinishing
kosherweb.co/browser

An Android browser built from scratch around kosher filtering.

Kosher Browser is a native Android browser (v1.0.0, ~3.7K lines of Java) designed for Hebrew-speaking families and institutions. WebView under the hood, but everything around it is custom: a DoH DNS client, a classifier client talking to Kosher Classifier, a parental admin panel, device admin for MDM enforcement, a blocked-page controller, and full RTL Hebrew UI. Release APK signed and ready.

Kosher DNSFinishing
kosherweb.co/dns

A filtering DNS resolver, with signed category feeds.

Kosher DNS is a Go-based filtering DNS resolver. It loads Response Policy Zone (RPZ) feeds signed with Ed25519, swaps categories atomically, and ships an SSE channel for emergency updates. ~1.9K lines of Go, eight regression suites, contract-compliant, no query logging. Ready to deploy on BunnyCDN, AWS Global Accelerator, or self-hosted.

Kosher ClassifierBuilding
kosherweb.co/classifier

Classifies domains the way a posek would — signed, auditable, pluralistic.

A REST API that classifies domains and URLs into 20+ religious and technical categories. FastAPI + PostgreSQL + Redis, Alembic migrations, 14 passing tests, docker-compose environment. Every taxonomy change is signed with Ed25519 and written to an append-only audit log. Halacha-protected categories are immutable; others ride a human-in-the-loop review queue. Crawler and ML classifier follow.

Kosher SearchBuilding
kosherweb.co/search

A Hebrew-first search engine over a rabbinically curated whitelist.

Kosher Search is a /v1/search provider for the ecosystem. Go service, Meilisearch index, curated whitelist of thousands of Hebrew-language kosher sites. Hebrew NLP (HebMorph, YAP) baked in so morphology actually works on queries. No tracking, no advertising, no profiling — the query is for the user, not for whoever paid for the ad slot.

Kosher PlatformBuilding
kosherweb.co

Community, supervision and identity for the kosher internet.

Three integrated apps in one monorepo: a community platform for schools and neighbourhoods, a supervision panel for rabbis and parents, and Keycloak-backed identity for everyone. Policy, analytics and device-fleet management for community admins. The business tier of the kosher stack — where DNS, classifier and browser turn into a product families pay for.

Kosher TrustBuilding
kosherweb.co/trust

A PKI so rabbis can sign websites as kosher, and every browser can verify.

Kosher Trust is a rabbinic Public Key Infrastructure. A rabbi signs a domain (Ed25519, scoped, time-bound) and publishes the signature to an append-only registry. The browser verifies on each load and shows a visible badge. Pluralistic — every rabbi owns their own chain, every user chooses which chains to trust. Contract 10 of the kosher stack.

Kosher VisionBuilding
kosherweb.co/vision

On-device image filtering with religious sensitivity — offline by design.

Kosher Vision is an on-device TensorFlow-Lite model that intercepts WebView images and hides non-tznius content before the pixel reaches the user. Four-level classification (NSFW → religious modesty → violence → symbolic). Embedded in the browser APK, ~5–15 MB quantised. Never leaves the phone. v0 POC in progress, deadline Q2 2026.

EventFundBuilding
eventfund.app

Crowdfund the event before you book the venue.

EventFund is conditional crowdfunding for events. The organizer sets a participant minimum and a payment per head; if the threshold is met, the event runs and funds release to the venue; if not, every participant is refunded automatically. Removes the financial risk of small communal gatherings — bar mitzvahs, lectures, group trips, niche meetups.
