About Luscinia
What it does
API Analyzer – Captures API failures (failed requests, error responses) from your browsing session and runs instant root cause analysis using AI (Gemini). You get likely causes and fix directions, plus Jira-ready tickets with editable content, full cURL commands, and optional test credentials—all stored locally and encrypted.
Responsiveness Analyzer – Tests the active page at desktop, tablet, and mobile viewports, then uses AI to report layout issues, overflow, touch targets, and other responsiveness problems, with Jira-ready tickets.
Issue Companion – Records screen activity and creates Jira tickets with AI assistance. Capture screen recordings, DOM activity, and screenshots, then use AI to enhance summaries and descriptions before one-click ticket creation.
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 and responsiveness
Product and business analysts who need to understand technical failures and layout issues quickly
Why Luscinia
Luscinia turns “something broke” into “here’s what went wrong and how to fix it,” and “does it work on mobile?” into “here’s what’s broken and how to improve it.” It’s built to be fast, clear, and focused on product teams—so you get from failure to fix with less guesswork.
