AI portrait blending that lets you hold the child you were and show them who you became.

Upload a childhood photo and a present-day selfie, and Gemini blends them into a Polaroid-style keepsake. It's part nostalgia trip, part self-reflection, wrapped in a real-time fullstack app with Convex and Clerk.

// PROBLEM

The Problem

We all have old photos tucked away somewhere. And we all wonder sometimes what our younger selves would think of who we've become. But there's no easy way to bridge that gap visually or emotionally.

// SOLUTION

The Solution

PastMeet uses Gemini 2.5 Flash to blend two portraits into one. Upload your past and present, and the AI creates a natural composite with Polaroid aesthetics, film grain, and gentle lighting. Share it to a public gallery or keep it private.

// HIGHLIGHTS
