PayGuard - Know who you're invoicing

PayGuard Know who you're invoicing before you send the quote. PayGuard is a risk-assessment tool for freelancers and independent contractors. Type what you know about a prospective client — payment history, communication style, anything you've heard — and PayGuard analyzes it for concrete red flags, assigns a risk level, and, when the risk is real, drafts a protective email proposing safer payment terms before you start work. Built for AI Factory — Native.builder Hackathon (lablab.ai × NativelyAI), August 2026. The problem Freelancers and small agencies routinely take on clients who turn out to be slow payers, non-payers, or difficult to work with — and there's rarely a fast way to check a client's reputation before committing time and effort. PayGuard gives freelancers a quick, structured way to sanity-check a new client using whatever information they already have. Who it's for Freelancers, contractors, and small agencies (dev, design, writing, consulting) vetting a new client before signing on. How it works Enter a client name and describe what you know about them — a warning from another freelancer, notes from a call, anything relevant. A Supabase Edge Function sends this to an AI model (via Groq), which: Extracts only concrete red flags actually present in the text (never invents risk that isn't there) Assigns an overall risk level: Low / Medium / High / Insufficient Data Gives 2–4 practical recommendations If risk is Medium or High, automatically drafts a protective email proposing a deposit, milestone payments, or escrow Results are shown immediately — no login, no data saved, fully stateless.
