A decision-quality journal for thesis-driven investors
Were you right, or were you lucky?
Log your thesis before you buy. Conviction extracts your claims and checks them against reality — so your process gets graded separately from your P&L.

01
What would prove you wrong?
A thesis that can't be wrong isn't a thesis. Entries refuse to save without a falsifier — that friction is the product, not a bug.
02
Reality checks you didn't ask for
Your stated range and falsifier thresholds are checked against price every day. When reality disagrees, you're confronted: still hold? Hold takes written reasons.
03
A score P&L can't fake
The Process Score grades falsifiability, completeness, pre-commitment, and follow-through. It never looks at returns — a lucky win can't buy a good grade.
Why not a spreadsheet — or a chat with an AI?
Spreadsheets are silently editable and never talk back. A chat only confronts you if you ask — and hindsight-you never asks.
Conviction keeps an immutable, timestamped record and does the confronting unprompted. Trade journals grade your execution. This grades your reasoning.
Your next decision deserves a record.
Log it before the outcome can distort it. The first entry takes five minutes.
