Sidenote is an AI reading assistant and document summarizer available through a Chrome extension and web dashboard. It is designed for students, researchers, analysts, legal teams, consultants and organizations working with internal documentation. The product summarizes webpages, PDFs, Word documents, PowerPoint files, research papers, wikis and connected documents, then attaches citations to source passages. Users can also chat with documents, generate glossaries, explain selected text, search semantically and create multi-document collections.

The free plan provides 3 documents, 10 standard-length summaries, 10 explanations, 3 glossary builds and 10 chat turns per month. Pro costs £10 per month or £96 per year and adds TL;DR, Standard and Detailed summaries, cited chat, collections, OCR for scanned PDFs, and Word and PowerPoint support. Pro+ costs £20 monthly and adds Claude Opus for chat, multi-document collections and Confluence space indexing. Pro Max costs £100 monthly for Opus chat at power-user volume. Team costs £18 per seat monthly or £14.40 per seat monthly when billed annually, with shared collections, centralized billing and SAML SSO with domain auto-join. A 7-day free trial is also available.

Sidenote fits teams that need source-linked answers across browser content, files and connected workspaces. Its integrations include Confluence, Notion, SharePoint, OneDrive, Google Docs, Gmail, Outlook, Google Drive and Slack canvases. Export options include Markdown, HTML, plain text and PDF, while shareable summary and chat links support distribution. Choose it if citations, document chat, OCR and cross-platform access matter; choose a lower-tier workflow if advanced collaboration, indexing or higher-volume Claude Opus access is unnecessary.
