In their own words
Eightify
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.
Sidenote
Sidenote is a browser-based AI reading assistant for asking questions about documents and tracing answers back to their source passages. Select a citation to jump to and highlight the cited text. It can summarize and explain documents, build glossaries, search files, and organize material with notes, highlights, tags, starred documents, and multi-document collections. It reads browser-rendered PDFs, including scanned PDFs with OCR, and accepts PDF, DOCX, PPTX, TXT, MD, MDX, and RTF uploads. Dedicated integrations include Confluence, Notion, Google Docs, Slack canvases, SharePoint, and OneDrive. Extensions are listed for Chrome, Edge, and Firefox; Opera is coming soon. The free plan allows 3 documents per month, while Pro is £10/mo billed monthly. A 7-day Pro trial requires no card and limits users to 10 documents, 20 summaries, and 10 chat turns. Users can choose to keep documents while their account is open or discard them, which purges a document within 24 hours. Sidenote says content is not used to train AI models, but it is not yet SOC 2 certified.
