Eightify vs Paperlayer

Eightify uses AI to summarize YouTube videos and identify key information. Its summaries include timestamps for jumping to a topic, an overview of top comments, and video transcripts; it also offers a transcript generator and can summarize transcripts. Users can shape key insights by choosing a focus, format, length, and grouping, then share summaries as links or export them. Summaries and translations are available in more than 40 languages. The Chrome extension listing says it handles videos up to 10 hours and is powered by Claude and ChatGPT. Eightify names podcasts, interviews, science and technology, business, investing, news, health, and personal growth as possible subjects. It is available on Android, iOS, web, and as a browser extension. A free plan and free trial are available. Eightify Pro costs $9.99 a month, billed monthly, or $59.99 a year, billed annually. It does not summarize webpages or accept file uploads. Eightify says it collects contact, device, and usage data and applies security measures, while noting that absolute protection cannot be guaranteed.

Paperlayer is a web-based AI reading layer for research papers, pairing summaries and contextual margin notes with evidence in the original PDF. You can find public arXiv papers by title or author, enter an arXiv ID or paste an arXiv link. Summaries cover the paper’s problem, method, results and caveats, while highlights mark claims, methods, results, problems and caveats with adjustable density. Margin notes explain terms, equations and figures beside the text. Summaries and notes support Korean, Japanese, Chinese, Spanish, French and German, and J and K keys navigate through a paper. Paper chat is marked “Soon.” The public demo covers public arXiv papers only and accepts no private or unpublished uploads. Paperlayer says live processing sends paper and request content to OpenAI over encryption without intentionally including account, cookie or anonymous identifiers.
