Gig Scam Shield: a private scam checker for side-gig hunters, powered by EmbeddingGemma in the browser

Description and use

Gig Scam Shield is a browser‑only web app that flags side‑gig job posts as safe, caution, or scam using a local EmbeddingGemma model and regex rules. It runs offline, preserves privacy, and costs zero per check.

Problem

Job seekers and group admins struggle to identify scam side-gig posts, risking time and money.

Outcome

The app achieves 9/11 correct verdicts on held-out posts, catching reworded scams missed by regexes, with zero marginal cost and privacy by design.

Workflow

• Paste job post into the web app
• The rules engine scans for regex-based red flags
• EmbeddingGemma generates an embedding of the post
• kNN vote against a small labelled reference set
• Combine rules and AI verdict, raising only if AI is higher
• Display verdict, red flags, and similar reference post

Evidence

Gig Scam Shield is a tiny, private scam checker for people hunting online side income, and for anyone who screens job posts for others
