MemoryBox: A Privacy-First Screenshot Search Tool Powered by Local AI

MemoryBox is a privacy-focused screenshot search tool that lets students, developers, and researchers find images using natural-language queries. The current browser demo requires manual uploads and relies on local OCR, the Gemma 3 4B vision model, and local embeddings for search. Its planned desktop version would index selected screenshots automatically, with user permission, and run open-weight models on the user's device.

Seven AI design tools tested on five identical free-plan jobs, ranked by output quality
