The closed loop for high-stakes decisions

Log decisions when they're made. Review outcomes on schedule. Learn patterns over time. Reflect OS is the operating system for how your best thinking gets captured, reviewed, and improved.

Built for executives, investment teams, and anyone who needs to get better at deciding

Structured logging at the moment of decision

Context, confidence, risks, and rationale — captured in a consistent format while memory is fresh.

Scheduled outcome checkpoints

Reflect OS pings you when outcomes are due. Compare what you expected with what actually happened.

Patterns across your decision history

Calibration scores, recurring biases, outcome quality trends. The insights you can't see without a structured record.

Everything a serious decision-maker needs

Reflect OS is not a note-taking app or a task manager. It's infrastructure for decisions — built around the closed loop of capture, review, and learn.

Decision log

Every decision captured with structured fields: context, rationale, risks, confidence, stakeholders, and situational notes. Fast to complete — nothing gets lost.

Outcome checkpoints

Set review milestones at 30, 90, 180 days or custom horizons. Reflect OS surfaces them at the right time — so outcomes are reviewed, not forgotten.

Decision intelligence

Calibration curves, quality scores, and pattern detection across your history. The app earns trust by showing you something true about how you actually decide.

Team workspaces

Share decisions with your team. IC votes, collaborative review, shareable decision briefs via secure expiring links — for non-users too.

AI risk assessment

Every decision gets a structured risk analysis. Surface what you might have missed, scored by severity and confidence, with mitigation suggestions.

Financial modelling toolkit

Run projections and scenario analysis within the decision record. Outputs stay linked to the decision that created them — not buried in a spreadsheet.

Built for decisions that actually matter

Reflect OS is designed for the contexts where decision quality has real consequences.

Executive & leadership teams

Capture strategic rationale, track decision outcomes over quarters, and build institutional memory that doesn't walk out the door.

Your reasoning is yours alone

Decisions often contain your most sensitive thinking. Reflect OS is built around the premise that what's private stays private — without compromising what the AI needs to work.

Full security details

End-to-end encryption for sensitive fields

Decision rationale and sensitive context fields are encrypted at rest. Not readable by anyone without your key.

Granular access controls

Workspace, team, and individual permissions. You decide who can see what — including coaches and advisors.

Full audit log

Every view, edit, and export is logged. Defensible records for governance and compliance.

The moment the app proves it knows something true about how you decide

"The first time Reflect OS flagged that I was consistently overconfident on decisions made under time pressure, I felt it before I could argue with it. That's rare."

Head of Strategy, PE firm London

"We'd been repeating the same diligence gap for two years. Reflect OS made that visible in about ten minutes of looking at our IC history."

Investment Director, VC fund Edinburgh

"Logging a decision used to feel like work. Now it feels like talking to a smart colleague who asks the right questions and files everything correctly."
