Explore who lived when, what happened where, and what was being created, discovered, or fought over at the same time — across civilisations and centuries.
Enter facts — people, events, periods — with dates going back to the earliest BCE. Upload a CSV or spreadsheet if you have a lot.
Assign tags by geography, discipline, era, or any grouping you invent. Tags are what build your timeline lanes.
Choose a mix of tags for each lane, pick a colour, and stack them. Drag lanes to reorder, zoom, scroll, and explore.
Dates span from ancient history into the modern era. Enter year, month, and day — or just the year.
Layer multiple timelines on the same board to see what Greek philosophers, Roman emperors, and Renaissance artists have in common.
Rearrange lanes with a drag handle. Your preferred order is saved and shared with anyone viewing the board.
Already have data in a spreadsheet? Upload a CSV or Excel file and Symeon maps it to entries and tags automatically.
Keep your research private, share selected entries with collaborators, or open a board to the world.
