Apogee
Apogee is a private browser extension that summarizes articles, videos, PDFs, and text locally.

It operates entirely on your device using WebGPU, WebAssembly, or local Ollama and llama.cpp servers, requiring no accounts, API keys, or cloud uploads. The tool supports interactive YouTube timelines, social thread parsing, local document reading, and smart Q&A retrieval with source sentence highlighting. It targets users seeking private AI assistance without data leaks. Set apart by its strict local architecture, it features custom standing instructions, multi-language translation, and per-page focus keywords.
