## Description

Sanity Check is a privacy-first browser extension that helps job seekers evaluate job advertisements with clear eyes. Highlight a job description or paste it into the extension and receive an instant analysis based on your own preferences. 

Configure the skills, technologies, keywords, and phrases you want to see, along with terms you'd rather avoid. Sanity Check provides:

• Match and mismatch scoring based on your chosen criteria
• Detection of custom warning phrases and employer red flags
• Plain-English explanations of phrases that may indicate unrealistic expectations, role scope inflation, social engineering, scams, or exploitative workplace practices
• Fully local analysis with no accounts, no telemetry, and no external services
• Customizable settings so you remain in control of the criteria used during evaluation

Unlike AI-powered services that send data to remote servers, Sanity Check performs all analysis directly within your browser. Your job searches, preferences, and assessments stay private. Whether you're reviewing a software engineering role, a data position, or any other opportunity, Sanity Check provides a calm second opinion before you invest your time in an application.
