SaaS

ReplyCurrent is an AI customer support SaaS I built to help businesses answer customer questions automatically. You connect your website, help center, or documents, and it creates an AI chatbot that answers visitors using your own content. It also supports lead capture, conversation tracking, and a dashboard to see what customers are asking. The goal is simple: help businesses save time on support while giving visitors quick, accurate answers.

Lie Dedector

TruthScan AI is an entertainment app that turns any iPhone into a party lie detector. It analyzes voice stress and 43 facial landmarks to detect micro-expressions and delivers a “truth or lie” verdict with a confidence score. Features question templates, video recording and sharing, and multi-person mode. Freemium model with subscriptions and coin packs. Live on the App Store with zero paid marketing so far; I built it solo and have no experience running ads, so all traction to date is organic.
