A private journal for better decisions.
DecisionOS helps you record the decision, schedule the revisit, and write down what your reasoning got wrong.

One surface for the whole decision.
DecisionOS does three things — and you can see all of them in a single workspace.
Captures reasoning
The options, trade-offs, and assumptions behind a call — structured, not buried in a thread.
Surfaces signals
It reads across your decisions and flags only what matters: a recurring risk, a review you owe.
Keeps decisions alive
Owners, status, and a revisit date carry each decision from consensus through to outcome.
Decisions decay the moment the meeting ends.
Context scatters across calls, docs, and threads. The reasoning behind a choice evaporates — and six weeks later, no one remembers why, so the debate starts over.
You become what you repeatedly decide. DecisionOS makes that compounding deliberate — it keeps your reasoning, not just the outcome, so your next decision starts from earned clarity instead of a blank page.

The cost of forgetting is paid by the next person who has to decide.
Four steps from scattered signal to aligned action.
Capture the decision, compare the paths, commit with a clear rationale, and revisit it when reality answers back.
Capture
Pull in the messy inputs and frame the decision.
Compare
Lay out the options and weigh the trade-offs.
Commit
Make the call with owners and a rationale you can audit.
Revisit
Come back on a set date and write what you got wrong.
Five surfaces, one calm instrument.
The whole system in one place — inspect any part without leaving the others behind.
It surfaces only what matters.
One calm attention surface ranks what genuinely needs you — a recurring risk, an overdue review — and stays quiet when nothing does.
- Severity-ranked and deduped
- Evidence attached to every signal
- High risk, no pre-mortemRisk
A critical-risk call was committed without naming how it could fail.
- Revisit overdueReview
You said you'd look back 6 days ago. The longer you wait, the less honest the review.
- Dominant constraint patternPattern
“Headcount” appears in 43% of constraint tags — a recurring blocker.

Built for decisions that deserve a second look.
Chat, docs, and dashboards each hold a fragment. DecisionOS is the one place the whole decision stays coherent.
- Persistent context
- Structured reasoning & trade-offs
- Pre-mortem & risk checks
- Execution & revisit loop
- Decision memory
Other tools cover one or two of these. None hold the whole loop — from reasoning to remembered outcome.
Questions, answered.
What DecisionOS is, how it works locally, and why the revisit loop matters more than another note.
A private decision journal for recording what you decided, why you decided it, and what you learned when reality answered back.
