Luscinia: AI-Powered Sidekick for Product Teams
Luscinia is a browser extension that helps product and engineering teams understand why API calls fail. Instead of manually digging through responses and logs, you get AI-driven root cause analysis in seconds.
What it does
Captures API failures (e.g. failed requests, error responses) from your browsing session
Runs instant root cause analysis using AI (Gemini) so you see likely causes and fix directions
Surfaces clear, actionable explanations—so developers and QA spend less time triaging and more time fixing
Fits into your workflow as a lightweight sidekick: no heavy setup, works where you already work
Who it’s for
Developers debugging APIs and integrations
QA engineers investigating test failures
Product and business analysts who need to understand technical failures quickly
Why Luscinia
Luscinia turns “something broke” into “here’s what went wrong and how to fix it.” It’s built to be fast, clear, and focused on product teams—so you get from failure to fix with less guesswork.
