LogicGrid Family Bot Live

A WhatsApp-native family archive — living family tree, photo vault, automatic birthday reminders, and an AI historian that answers questions about your family from its own records. No app to install; it runs entirely inside an existing WhatsApp group. Built for extended-family structures, with SafeRelay's engine scrubbing sensitive data from every message before storage.

Our story

Built by an engineer who wanted AI speed without giving up security

LogicGrid AI is led by MJ — a Linux and DevOps engineer with more than a decade of experience across infrastructure, containers, security, and distributed systems. The security training came early, and it stuck: a deep, reflexive caution about untrusted systems and sensitive data.

That caution collided with the speed of generative AI. The collision became LogicGrid.

The origin

While building a WhatsApp platform for families and communities back home in Nigeria, AI coding tools compressed weeks of work into hours. But the speed created a new problem. Logs, webhook payloads, config snippets — and occasionally values that should never have left a terminal — were getting moved by hand into AI chats.

The same engineer who had spent years telling people not to expose credentials was doing the AI equivalent. And the workflow itself was a grind: copy, Alt-Tab, paste, switch back, repeat.

"I wanted text to move the way files move in Linux — captured, redirected, and sent exactly where I wanted, without exposing what should stay private."

What came out of it

SafeRelay. Highlight text anywhere, press one hotkey, and it relays into the right place — AI tool, editor, ticket, terminal — in milliseconds, with the sensitive parts stripped out locally on the way. Fast enough to stay in your flow. Safe because the redaction never leaves your machine. Accurate because it's built on purpose-made detection patterns, not guesswork.

It shipped across the browser, VS Code, the CLI, Docker, an SDK, and a signed Windows desktop agent — on a hardened CI/CD pipeline.

What LogicGrid builds

Practical infrastructure and workflow tools for people and organizations that need speed, accessibility, and security at the same time — spanning secure AI workflows, local-first data protection, WhatsApp-first services, and developer tooling.

The throughline is simple: build security in, ship it for real, and let nothing leave the machine that shouldn't.
