Show HN: MemeOS – The Ultimate Meme Operating System (iOS)

Hi HN, the creator of MemeOS here.

I built MemeOS because I was tired of the current state of meme generators. Most existing mobile apps / websites are either riddled with ads, have outdated templates, or are just simple image captioners without real editing power.

MemeOS is a native iOS app designed to treat memes as a serious medium. I wanted to build something that feels like a "pro" tool but for something as fun as memes.

Key Features:

AI Meme Maker: I built an agentic workflow using Supabase Vector Search. You can describe a situation or feeling, and my "Meme Maker Agent" (yes, I really built a meme agent!) will find relevant templates and suggest captions.

Professional Editor: Layer-based editing, and precise text controls. It feels more like a mini-Photoshop for memes than a simple captioner.

Meme Lore: Every meme has an origin story. I use AI to research and write the history ("lore") of each template, so you know exactly where it came from and how to use it correctly.

The Tech Stack:

Backend: Supabase (PostgreSQL).

Frontend: SwiftUI (100% native iOS).

AI/Search: Supabase Vector for semantic search of templates and RAG for the "Lore" generation.

Edge Functions: Deno runtime for the heavy lifting of AI coordination.

The app is free to try. I monetize through a separate subscription for power users (AI tools, premium assets, watermark removal), but the detailed Meme Lore and the core editor are accessible to everyone.

I’d love to hear your feedback on the editing feel. I am actively tweaking the vector search weights, so any examples where the AI "missed" the vibe would be super helpful!
