Daily Lowdown is reimagining how people stay informed. We built an AI-native journalism platform that delivers a beautifully written, fully personalised daily email newsletter — Monday to Friday — covering exactly the topics each reader cares about most. Every morning at 8am local time, our readers wake up to a concise briefing tailored entirely to them. They choose up to six topics — anything from climate tech and geopolitics to Formula 1 and personal finance — and our AI scours the internet for the latest developments, synthesises what matters, and writes it in the kind of clear, engaging prose you'd expect from a great journalist. No noise, no algorithm-driven outrage, no doom-scrolling required. We're bootstrapped, remote-first, and deeply focused on one thing: making the daily news habit feel effortless and genuinely worth it.

What we are building: Nullgen is a localized data loss prevention (DLP) browser extension and administrative platform. The product operates on a freemium model, with the premium enterprise and education tiers offering centralized management, zero-touch MDM deployments, and tamper-proof policy enforcement. The hard problems we are solving: - Enterprise Shadow AI: Employees constantly leak proprietary company code and sensitive financial data into unvetted public LLMs. We stop this data loss locally before the prompt ever hits the network. - K-12 Academic Integrity: Students easily bypass traditional DNS school filters to use AI for essays and tests. We provide district IT administrators with an impenetrable, device-level roadblock. - Privacy-Preserving Security: Traditional DLP software requires routing traffic through third-party servers. Because our custom ML model runs entirely on the user's local device, zero payload data ever leaves the machine, ensuring total data privacy and massive reductions in cloud compute costs.
