Decisum captures the context behind your decisions—so anyone can understand what happened months later, in minutes.
Teams make thoughtful choices with the right context at the time.
People join, leave, or forget. The why behind decisions disappears.
Project leads become the source of truth, explaining the same things over and over.
Decisum extracts what matters from your existing workflow and builds a timeline anyone can follow.
Each project has a unique email address. Forward relevant threads and Decisum extracts what matters.
Drop in meeting notes, specs, or proposals. Important context is captured automatically.
Decisum generates brief, structured timeline entries. Decisions, assumptions, surprises—all categorized.
Review, edit if needed, and confirm. You stay in control—AI assists, but you decide what matters.
Six months from now, anyone can understand how your project reached its current state in ten minutes.

Client projects require explainable decisions. When handovers happen, context needs to transfer cleanly.
Cross-functional work means many stakeholders. Stop being the person who "remembers why."
Long-running projects accumulate decisions. New team members should understand the history without a meeting.
