Project History shows you a complete timeline of changes to your model. Every time you save, Aire captures what changed, who made the change, and when it happened. You can see old and new values side by side, trace when formulas were updated, and understand how your model evolved over time.History is automatic—you don’t need to turn it on or configure anything. Every edit to a term, block, formula, or structure is tracked as you work.
When multiple people edit the same model, history creates transparency. You can see what your teammates changed since you last looked, review their work before building on it, and avoid accidentally undoing someone else’s updates.
For regulated projects or investor reviews, Project History provides a complete audit trail. Every change is timestamped and attributed to a specific user, creating a permanent record of how assumptions evolved.
If outputs suddenly look wrong, trace back through the timeline to see what changed. Maybe someone updated a formula, or a key assumption shifted. History helps you identify when things diverged from expectations.
If you rename a term, update its value, and add a tag all in the same save, those changes appear as separate entries but stay grouped together under that save. This makes it easy to see all related edits at once.
Each scenario (like “base case” or “optimistic”) has its own independent history. When you switch scenarios, you see how that specific set of assumptions evolved, not a mixed timeline from all scenarios.
