In their own words
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.
TLDR This
TLDR This summarizes articles and other text, with inputs ranging from a webpage address or pasted text to PDF, DOC and DOCX files up to 25 MB. Its AI generates concise summaries, while article extraction can identify the author, date, title, related images and estimated reading time. Browser extensions summarize webpages in one click, and a PDF chat feature lets students, researchers and professionals ask questions about research documents. Other tools paraphrase text in different voices and styles, filter weak arguments and speculation, and surface relevant points. A reading view removes ads, popups, graphics and other online distractions. The service also provides API access through a link to RapidAPI. TLDR This has a free plan and paid plans, including Starter at $4 a month. The Free plan includes unlimited basic summaries, 10 advanced AI summaries and up to 10 paraphrases as one-time allowances. The service says uploaded files are not opened unless requested and personal information is not sold to third parties. Data is encrypted in transit and at rest; deleted data is purged within 30 days.
