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.
