Authenix

Note

Authenix is the new name for the project formerly known as SatoriCheck. While the branding and frontend have been updated, internal codebase references (folders, database files) may still use the legacy name to ensure stability during the transition.

Fully vibecoded, AI-powered fact-checking app with live audio transcription, Meta Analysis for quote claims, Pitch Deck fact verification, media ai/authenticity analysis and Stripe billing, using antigravity IDE.

Status: In Production, Active Users. Mission: Provide instant, credible verification of claims using advanced AI and source grounding.

Features

• Live audio with Standard (browser-based speech recognition) or Pro (Deepgram transcription)
• Pitch Deck Check — Verify claims in startup pitch decks (Gemini)
• AI Fact-Checking — Google Gemini with web search grounding and Grok.
• Media Authenticity — Analysis of images and videos for AI generation and manipulation
• Smart Agent — Auto-separates multiple claims for individual verification and meta level analysis.
• Social Sharing — Generate shareable cards for verified claims for X & Linkedin (Privacy-first)
• Streak System — Daily login rewards with CP bonuses
• Token Billing — Stripe integration for Check Points (CP)
• Google OAuth — One-click sign-in.
• Account Deletion — GDPR-compliant data erasure with anti-abuse protection.
• Browser Extension — Universal highlighting and fact-checking integration for Chrome via API tokens.
