genei vs Sidenote

genei is an AI-powered research and note-taking tool for analysing webpages, documents, and PDF files.

Its natural language processing supports abstractive summarisation, entity annotation, semantic search, and question answering. The web app organizes documents into projects and supports comments, highlights, custom definitions, and notes. It also provides citation management and reference generation for uploaded documents. The Chrome extension can summarise webpages or save them for later reading. genei supports PDF and web.x files, but currently handles English-language documents only and is designed for desktop rather than mobile devices. The free Extension plan offers one-click webpage summaries. A 14-day trial is listed, and the pricing note lists paid access from £3.99/user/mo on annual billing. Separately listed monthly plans are Genei Basic at $5.49 a month and Genei Pro at $20.99 a month; Pro adds multi-document summarisation, search, and question answering, along with other features. The terms describe personal and non-commercial use, with enterprise subscriber access for authorised institutional users.
