A research or history timeline that holds its evidence: events from seconds to centuries, a source on each, chapters, filters, a map, and CSV or PDF export.
Research turns up dated facts faster than a document can absorb them, and a spreadsheet holds a decade without ever letting you see it. Boromlia keeps them as one chronology you can read, filter, map and cite.
What you get
Any time scale in the same tool: four hours of telemetry or nine centuries of parish records.
A source on every event, and a filter that lists the ones still unsourced.
Chapters for periods and tags for themes, so a long record has a table of contents.
A map of every located event, for when the question is where the evidence clusters.
A CSV that round-trips: export it, work on it in a spreadsheet, import it back on Advanced.
From field notes to a chronology
Events are single moments or ranges, which is what a reign, a tenure or a field season really is. Each one carries rich text, people, a place with real coordinates and as many images as it needs.
Bulk photo upload reads the date and GPS position out of the files, so a folder of fieldwork photographs becomes dated, placed events without typing. The PDF export is a document rather than a screenshot: a title sheet with the period and counts, then a dated column with the images in the text.
AI finds material. A research timeline shows what holds up.
Ask an assistant about a period and you get a fluent answer with dates in it, some of them wrong and none of them tied to where they came from. A research timeline is the opposite: fewer words, every event dated, and a source you can open and check.
The useful split is simple. Let AI help you search and draft. Put what survives checking on the timeline, with its source. When two sources disagree about a date, both events sit on the same axis and the conflict stays visible instead of being averaged away.
Views worth leaving open
River: A reading shape for a long chronology: a line with cards either side of it.
Map: Where the evidence clusters, rather than when.
Log: On Advanced: every event as a sortable row, for counting and cross-checking.
Questions
Can I keep a source on every event?
Yes. Every event has a source field of its own, and "has a source" is one of the filters, so the unsourced events in a long chronology are one click away.
Can I work at a scale other than days?
Yes. A timeline’s horizon runs from seconds through minutes, hours, days and months to years. Changing it redraws the same events against a different axis; it does not alter what is stored.
Can a colleague add to it?
Yes, on Advanced. Collaborators add events alongside the owner, and a read-only link lets a wider group read it.
