Some additions to this list

1. Consensus (consensus.app) (Developer: Consensus) Consensus is an AI-powered academic search engine that searches through over 200 million scientific papers and synthesizes research findings directly. Unlike general AI tools, it cites peer-reviewed sources for every claim, making it an essential tool for anyone doing evidence-based research. It is one of the most popular research-specific AI tools and is widely used by students, academics, and professionals.

2. Elicit (Developer: Elicit) Elicit is an AI research assistant that automates literature review by finding, summarizing, and extracting data from academic papers. It is purpose-built for researchers and is frequently cited as a top tool for systematic reviews and evidence synthesis. Its exclusion alongside ChatPDF and Phind is a significant gap.

It has become extremely popular for processing research papers, reports, and long-form content, and should not be overlooked.
