What it does

Tracks how the conversation around a competitor's app changes release-to-release. It pulls fresh reviews, classifies each into topics (performance, pricing, bugs, UX, features), stores them in BigQuery keyed by app version, then diffs the topic distribution of the latest version against the previous one. Any topic that moved more than a set threshold gets surfaced as a shift.

When to use it

Use it to catch a competitor's regression or wins in near-real time — e.g. a new version suddenly drawing crash complaints, or a pricing change generating backlash you can exploit in positioning. Good for PMMs and competitive-intel teams monitoring 1-5 rival apps.

How it works

  1. 1A weekly schedule fires the run.
  2. 2Apify scrapes the most recent reviews for each tracked app, including the version each review targets.
  3. 3OpenAI classifies every review into a fixed topic taxonomy with a sentiment score.
  4. 4The classified rows are appended to a BigQuery table partitioned by app and version.
  5. 5A BigQuery query computes the topic-share delta between the newest version and the prior one.
  6. 6A logic step keeps only topics whose share moved past the threshold.
  7. 7The ranked shifts are posted to a Slack channel with example quotes.
