How Jev is used
- Role in the product flow
- On-page personalization routing (headline, layout, copy selection)
- Primitives
- Choice
- State in
- Visitor or segment context plus variant catalog (inferred from showcase description; no open-source schema on this directory).
- Decision out
- Selected headline and layout variant per visitor according to the launch clip.
Ploy uses Jev for discrete variant selection rather than generating entire pages from scratch on every request, per the attributed launch clip. This profile does not claim internal Ploy schemas beyond what Bryant Chou published; treat ploy.ai as the product source of truth for funnels and analytics.
Sourced performance claims
