Lines turns history into stories you can feel. Search for any historical figure — from world leaders and scientists to artists, activists, and explorers — and instantly generate a beautifully crafted timeline of their life. Each event is researched by AI, verified against multiple sources, and presented in an editorial reading experience that feels like turning the pages of a book. DISCOVER REMARKABLE LIVES Browse timelines of the people who shaped our world. Search by name, or explore by domain, era, cultural region, and archetype. From ancient philosophers to modern-day pioneers, every life tells a story worth reading. AI-POWERED RESEARCH Lines uses a multi-stage research pipeline to build each timeline. It searches across Wikipedia, Wikidata, Google Knowledge Graph, and the open web to gather the most reliable information available — then uses AI to weave it into a compelling narrative of 15 to 30 key life events. FACT-CHECKED WITH REAL CITATIONS Every event in a timeline is backed by verifiable sources. Expand any event to see where the information came from — including source type, publisher, relevant quotes, and direct links to the original material. Lines doesn't just tell you what happened; it shows you where it's documented. EDITORIAL READING EXPERIENCE Swipe through life events one page at a time in a clean, book-like interface. Serif typography, thoughtful spacing, and a distraction-free layout let you focus on what matters: the story. SMART FILTERING & DISCOVERY Find people by what they're known for. Filter by domain (science, politics, arts, sports), cultural region, historical era, or archetype (visionary, rebel, pioneer). Discover connections across time and culture you never expected. YOUR PERSONAL LIBRARY Every timeline you generate is saved to your library. Come back anytime to revisit a life, pick up where you left off, or share what you've learned. BUILT FOR CURIOUS MINDS Whether you're a student researching a paper, a history enthusiast exploring a new era, or simply someone who loves a great story — Lines makes the lives of extraordinary people accessible, engaging, and trustworthy. Start exploring. Every life has a story.
