Keep a project’s history on one timeline: phases as bars, milestones and decisions as dated events, and a PDF or CSV whenever someone asks what happened.
Six months after a launch, somebody asks why it slipped, and the answer is spread across a standup, a chat thread and a document nobody can find. Boromlia gives the project one dated record: every phase, decision and change in order, with the evidence attached.
What you get
Phases drawn as bars, milestones and decisions as points on one axis, so you can see what overlapped and what slipped.
Each decision dated, with the ticket, message or document it came from in its source field.
Tags such as "scope change" or "vendor" that pull one thread out of a two-year project.
A post-mortem PDF or a CSV for a stakeholder, filtered to exactly the events they asked about.
How a project timeline works
Add events as the project moves. A spike that ran two weeks is a range; a go/no-go call is a single date. Chapters split the timeline into phases, discovery to rollout, so two years still read in one pass.
Export follows the screen. Filter to the events tagged "incident", press export, and the post-mortem appendix is an A4 PDF or a CSV of every field. On Advanced, collaborators add events to the same timeline, and the whole record opens as a sortable table in the Log style.
Why keep a project timeline when AI can summarise the threads?
An assistant can summarise the messages it is shown. It cannot tell you which of three dates in them was the real deadline, or that a call in week twelve quietly reversed one made in week four. That takes one dated record a person has checked.
The two work well together. Paste meeting notes into an assistant, ask for a CSV with date, title, description and source columns, and import it on Advanced, reviewing every row before it is saved. Going the other way, export the CSV and give the assistant a clean, ordered history to summarise instead of a pile of messages.
Views worth leaving open
Spans: Phases as bars and decisions as points on one axis, which is what shows the overlap.
Cards: A quarter at a glance, when the detail is not what you need.
Log: On Advanced: one sortable row per event, in the same shape the CSV export writes.
Questions
Is this a Gantt chart tool?
Partly. The Spans style draws start-and-end events as bars on a shared axis. There are no dependencies, no critical path and no resource levelling: Boromlia records what happened rather than scheduling what will. Keep your planning tool and use this for the record.
How many events fit in one project timeline?
The free plan holds one timeline of up to 20 events. A $2.99 slot, bought once, adds a timeline of up to 50. Advanced removes both limits for $12 a month, which is what a long project usually needs.
Can my team add to the same project timeline?
Yes, on Advanced. Collaborators add events alongside the owner, with no seat to buy for each of them. Visibility, style and settings stay with the owner.
