Public launch
Cortex is in general availability. Auth, real-time candidate scoring, calibrated winner-probability, divergence heatmap, brand-signature builds, leave-one-out validation, Stripe billing with overage, role-based workspaces, audit log, and the full UI redesign all ship together. Free 14-day trial, no card.
Production environment wiring
Live cortexads.ai, custom domain, production Supabase, Resend transactional email from hello@cortexads.ai, Sentry error reporting, Stripe live mode. Health-check page, env-var guard at deploy time.
Stripe billing & metering
Three plans — Starter ($99/mo, 30 scorings), Growth ($299/mo, 200 scorings), Agency ($799/mo, 1000 scorings) — with per-scoring overage. Customer portal redirect, trial period, hard caps configurable per plan, failed scorings released from the monthly quota and never billed.
Hardening & polish
Rate limiting on every public endpoint, audit log for privileged actions, role-based access control (owner, admin, member, viewer), invitation flow with expiring tokens, account deletion path.
Candidate scoring
Upload a candidate ad, get a calibrated winner-probability in under four minutes. Three-score breakdown (final, winner-likeness, attention), six-network brain-activity timeline, second-by-second divergence heatmap, plain-English narrative.
Brand signatures & references
A brand's reference library — historical ads tagged as winners or losers — is the source of truth for that brand's signature. Build a signature from the library, see leave-one-out validation against itself, edit per-reference weights when one ad needs to count more or less.
