Dozens of categories. Thousands of real outcomes. Each figure is the actual regret rate - not modelled, not surveyed. Real people, years later.

Synthesis.
You describe your decision. We read across thousands of structurally similar outcomes and surface what actually mattered - across one year, five years, a decade.
Semantic matching
Not keyword search
Describe your situation in plain language. We find decisions that share the same underlying structure - same stakes, same fear, same tradeoff - not just the same words.

Longitudinal patterns
Tracked over time
We track the same decisions at year one, year three, year five, year ten. The AI identifies when regret peaks and when - and whether - it fades. Most tools show you a moment. We show you the arc.

Wisdom extraction
What they wish they knew
Every submission includes what the contributor wished they'd known beforehand. Our AI reads across hundreds of these and surfaces recurring patterns - not cherry-picked quotes, but statistically consistent insight.

qualitative narratives distilled into data-driven, actionable insights
Query
"Should I leave my VP role at a large company to join a 12-person startup as a founding team member?"
AI
Across 15 matched decisions in our database, the AI identified recurring themes: financial uncertainty peaks early, but those who prioritised team culture over compensation reported lower long-term regret. Every insight is drawn only from real submitted outcomes - zero AI hallucination.

Built like a dataset.
Not like a forum.
Every submission follows the same 14-field structured schema. Outcomes are tracked at multiple points over years. 2.5% of submissions are rejected for inconsistency. This is how we keep it useful.
Structured schema
14-field structured formatNo free-text-only submissions. Every entry follows the same 14-field form - decision type, context, outcome timeframe, regret score. Comparable, queryable, aggregatable across all categories and 0 countries.
Longitudinal tracking
Year 1, 3, 5 follow-upsWe contact contributors at year one, year three, and year five to reassess their regret. Tracking how decisions feel over time - not just in the moment - is what makes this archive different from a survey.
AI grounded in data
Zero hallucinationOur AI reports are generated exclusively from real decisions in our database. Every claim is traceable to actual submitted outcomes. The AI sees only your matched decisions - never its own training data.
No advertiser influence
User-funded modelWe don't take advertising. Our revenue comes from subscriptions and credit packs. That means no outcome is ever shaped by who pays us. The data says what it says - including when the answer is uncomfortable.

The Regret Curve -
how it changes
with time
Most data captures a single moment. Ours tracks the same decision across 1, 3, 5, and 10+ years. The pattern is almost always surprising - and almost always hopeful.
"How people feel about a decision at year one is almost never how they feel at year five. The arc matters more than the moment."
