What it is #
whoblinked watches your competitors’ catalogues and tells you what they launched, discontinued and repriced. I co-founded it and have been CTO since July 2026. The code is private.
I built it end to end, from the data model and API contracts to the React product. It is multi-tenant.
How it works #
- Extraction with fallbacks. Each scan tries the store’s API first, then structured markup on the page, then a headless browser.
- Block detection. A scan that was blocked or failed is recognised as such, so it never shows up as a change in a competitor’s catalogue.
- LLM features. Competitor discovery, gap analysis and ownership research. Model output is checked against live search results before a user sees it.
- Cost and release. Every LLM call has its cost tracked, and an automated test-and-release pipeline gates deploys.
