Constraint diagnosis
Sophie names your single binding constraint using Goldratt theory of constraints. Not a list of 12 problems — the one that, if fixed, unlocks everything else.
See the methodology →Citation discipline
Every claim Sophie makes cites a framework slug, a peer-reviewed paper DOI, or an operator-essay URL. No hallucinated references. A NEVER_MENTION canary list catches confabulated vendors.
360 fw / 607 papers / 636 essays / 4364 cites →Vertical-native vocabulary
Sophie speaks the language of your vertical: DTC blended MER + cohort contribution margin, Fintech RAROC + three-lines-of-defense, ProfSvc utilisation × realisation × leverage, SaaS MEDDPICC + Magic Number net of S&M.
Try a vertical preview →Memory continuity
Sophie remembers what you discussed last week, tagged by archetype and vertical. Return to a Discount-Addiction conversation and she opens with the prior turn — no fresh-session amnesia.
Live in workspace →Public methodology
Every reasoning step is documented at /sophie/method. The 12-pillar × 4-dimension GRIP scoring formula is open. The 22 calibration rules are open. The independent-grader rubric is open. No black box.
Read the methodology →Independent weekly grader
Every Wednesday a Haiku 4.5 second-opinion model grades 30 sampled Sophie answers against a public rubric. Last week's average: 95.2 / 100. Failing cases trigger calibration the same day.
See live stats →Six native languages
Sophie thinks and writes natively in English, French, German, Spanish, Polish and Dutch. Every framework, archetype, helpdesk entry and answer is human-authored by a native speaker — never machine-translated.

When the answer matters more than the latency, you want sources, scoring, calibration, and memory. That is Sophie.
