Chronos Timeline

Chronos is a historical timeline visualization tool built for people who actually care about history. If you've ever tried to plot the fall of Rome, the rise of the Han Dynasty, or the history of mathematics on a timeline — and watched your software break the moment you entered a BCE date — you know the frustration.

Most timeline tools are designed for corporate project management: Gantt charts, product roadmaps, quarterly planning. They work fine for modern dates, but they weren't built for history. They break on negative years, they look like they were designed in 2005, and they make simple tasks unnecessarily complicated.

Chronos is different. Enter any date — positive or negative — and it just works. No workarounds, no hacks, no converting BCE to fake positive numbers. The Big Bang? 13.8 billion years ago? No problem.

Key features:

BCE dates that actually work Bulk upload dozens of events at once Add rich descriptions to each event Compare multiple timelines side by side (Pro) Merge timelines into one view (Pro) Folder organization to keep your timelines organized (Pro) Beautiful dark theme that actually looks good Shareable links to share with fellow history enthusiasts Community gallery to browse and save timelines created by others

The free tier gives you 10 timelines with full features — BCE support, bulk upload, descriptions, instant editing, and shareable links. Pro unlocks unlimited timelines and advanced features like compare, merge, and folders. Built by a history buff who spent years frustrated with the alternatives. Chronos exists because the tool I wanted didn't exist — so I made it.
