Apogee
Apogee is a browser extension that summarizes webpages, videos, emails, PDFs, DOCX files, and text pasted into it.
What Apogee is
Apogee is a browser extension that summarizes webpages, videos, emails, PDFs, DOCX files, and text pasted into it. It runs models in the browser using WebGPU or WebAssembly, or can connect to a local Ollama or llama.cpp server. Once a model has been downloaded and cached, it can work offline. The extension extracts readable webpage text, including through site-specific extractors for Reddit, GitHub, Wikipedia, and arXiv. For YouTube and Bilibili, it creates timestamped timelines linked to moments in the video. It can answer questions about long documents by retrieving relevant passages and produce summaries in 32 target languages. Picked files are limited to 50 MB, while pasted or plain-text input can contain up to 100,000 characters. Summarizing selected text requires at least 20 characters on a supported page. The maker says content and results stay off cloud services and third parties, and that Apogee collects no usage or performance data. It is MIT licensed and free at no cost, with no subscription, API key, or account required.
