Timeline-O-Tron

About

History deserves better than a bullet list. Timeline-O-Tron lets you build beautiful, interactive timelines on the Mac, iPhone, and iPad. Whether you're tracking the Apollo missions, mapping out the Beatles discography, or charting the rise and fall of empires, every event gets the detail it deserves. CREATE WITH PRECISION Add events with year, specific date, description, notes, color, and tags. BCE dates are fully supported — the Great Pyramid (2560 BCE) and the Moon landing (1969 CE) can coexist on the same timeline, rendered correctly and proportionally. VISUALIZE YOUR STORY Your timeline draws itself on a scrollable, zoomable canvas. Zoom from 0.1× to 200× and watch month markers appear, then days. Events stack intelligently above and below the axis so nothing overlaps. Animated transitions keep everything smooth. ORGANIZE AND FILTER Ten colors. Unlimited tags. Filter by either one, search by text. Color-code eras, categories, or themes — then toggle any of them on or off to focus on what matters. Sort by year or alphabetically. MEASURE AND ANALYZE Tap two events and instantly see the time between them — down to the day. Add notes to any event or to the timeline itself. GENERATE WITH AI Type a topic — "History of jazz," "Ancient Roman emperors," "Marvel Cinematic Universe" — and let AI do the research. Or paste an article and watch it transform into a structured timeline. Works with OpenAI and Anthropic. Your API keys are stored in macOS Keychain, never in plaintext. Typical cost: a few cents per timeline. EXPORT EVERYWHERE Export to JSON for portability. Export to CSV for spreadsheets. Export to HTML and get a fully interactive, standalone website — with zoom, pan, keyboard shortcuts, dark mode, and mobile support. No server required, works offline, zero dependencies. CROSS-PLATFORM WITH iCLOUD Native on Mac. Native on iPhone and iPad. Share your timelines across devices through iCloud. Research on your Mac, present from your iPad, check a date on your phone. KEYBOARD-FIRST ON MAC Full menu bar with comprehensive keyboard shortcuts. ⌘N to add, ⌘D to duplicate, ⌘0 to fit the timeline, ⌘⇧G to generate with AI. Right-click context menus, double-click to edit. It works the way Mac apps should work. BUILT-IN EXAMPLES Three richly detailed timelines ship with the app. Track every crew member from Mercury to Apollo 17. Follow the Beatles from Please Please Me to Let It Be. Examine all of Hitchcock's films in order. ROCK-SOLID PRIVACY No data collection. No analytics. No telemetry. No third-party SDKs. Your timelines are yours. We don't know who you are, what timelines you make, or how often you use the app. Create three timelines for free. Unlock unlimited timelines with a single, one-time purchase — no subscription.
