Open-source quality copilot for WeChat Official Account (公众号) authors. Export your own published-list metrics with a privacy-first Chrome MV3 extension, or paste interchange JSON/CSV into an Agent running the gzh-review skill. Get a fixed four-block report: conclusion → factors → title candidates → shippable experiment, with honest degradation when article count is low. No recommendation guarantees, no competitor scraping, no project cloud account for your data.
