Connected Papers

ResearchRabbit

ResearchRabbit is a literature review tool that helps researchers discover, organize, and understand scholarly papers through visual mapping of citation and topic connections, rather than plain keyword search lists. It draws on a database of over 310 million academic papers and shows how topics relate and evolve over time. The platform lets users organize papers and take notes to avoid losing track of ideas across a research project, and it integrates with reference managers like Zotero. It reports being trusted by over 1,000,000 researchers worldwide, including users at institutions such as Harvard, Stanford, MIT, Oxford, and Cambridge, and offers free sign-up.

Semantic Scholar

Semantic Scholar is a free research discovery platform built by the Allen Institute for AI (AI2). It indexes more than 237 million academic papers across every scientific field and uses AI to surface relevant literature, highlight connections between papers, and help researchers cut through the volume of published work. Beyond basic search, its Semantic Reader feature (in beta) adds contextual augmentation to make papers easier to read and cross-reference, while a Scholar's Hub provides organizational tools for tracking papers of interest. A public API lets developers build their own applications on top of the same paper corpus, and the entire platform is free, reflecting AI2's stated mission that research access should not require deep pockets.

WisPaper Search

WisPaper Search is an AI-powered literature discovery platform focused on helping researchers find academic papers through deep search. Instead of relying solely on exact keyword matches, the tool aims to understand the meaning behind a research question and surface relevant scholarly work from across the academic landscape. It is built around the idea that finding good literature should feel like asking a knowledgeable assistant rather than scrolling through endless search results. The platform is delivered as a web-based application, so users can access it from any modern browser without installing software. Its search workflow is designed for researchers who need to explore a topic quickly, whether they are starting a literature review, checking related work, or trying to stay up to date in a field. By using AI and deep search techniques, WisPaper Search attempts to go beyond traditional database search and make the discovery process more intuitive. While the public launch page does not provide exhaustive technical details, WisPaper Search is aimed at students, academics, and professionals who work with scientific papers. It is particularly useful for tasks such as scoping a research question, finding references, and identifying connections between publications. For researchers who want a faster, more conversational way to discover literature, WisPaper Search offers a promising bridge between modern AI interfaces and academic search.

EssayPass

EssayPass is an AI-powered academic writing assistant designed to help students, researchers, and academics turn scattered ideas into structured, scholarly drafts. The platform walks users through a complete workflow — uploading an assignment topic or draft, generating a logical outline and comprehensive first draft, and then refining the final version with an AI agent editor. It is built specifically for higher education, with output trained on academic datasets to maintain a formal, objective, and logical tone. It claims to serve more than 5 million academics and has generated over 50 million drafts, with a 98% satisfaction rate. Key features include automatic citation suggestions in APA, MLA, or Chicago formats, originality checks against online databases, paragraph-level bilingual support for ESL students, and bonus packages with citation references, mind maps, and FAQ packs. The platform also auto-generates tables, charts, and images, and offers five free revisions per essay to help students polish their work before submission. EssayPass positions itself between traditional essay tutoring services and generic AI chatbots, offering a lower cost per word than tutoring while avoiding common generic-AI pitfalls such as hallucinated sources and unstructured output. The service emphasizes privacy and integrity: drafts are encrypted, data is not sold or used for third-party advertising, and every essay is freshly generated with originality in mind. For students seeking a research-oriented drafting companion rather than a replacement for their own thinking, EssayPass provides an accessible, transparent path from blank page to final draft.
