Both tools use graph analysis algorithms to surface the most influential and relevant papers. Inciteful processes 200 million+ papers and is completely free to use, making it accessible to researchers at institutions without expensive database subscriptions.
🤖
Typeset (SciSpace)
Freemium
SciSpace by Typeset is an AI research platform for reading, writing, and discovering scientific literature. Its Copilot feature lets researchers highlight any text in a paper and ask questions about it, getting instant AI explanations of complex concepts, equations, and tables. The literature review tool searches 200 million+ papers and generates structured summaries. SciSpace also provides a publishing platform for formatting papers to journal templates. Used by 15 million+ researchers for paper comprehension and discovery.
🤖
Explainpaper
Freemium
Explainpaper is an AI tool that helps researchers and students understand difficult academic papers by providing instant explanations of highlighted text. Upload a PDF, highlight any confusing passage, equation, or technical term, and receive a plain-language explanation powered by GPT-4.

🤖
Keenious
Freemium
Keenious is an AI research recommendation tool that analyses any text you write or paste and recommends the most relevant academic papers based on your content. It integrates directly into Word, Google Docs, and web browsers, surfacing related research as you write without requiring explicit search queries. Keenious helps writers, researchers, and students discover relevant literature they would not have found through traditional keyword search, improving the comprehensiveness of academic work.
🤖
Elicit
Freemium
Elicit is an AI research assistant that automates literature review by searching, summarizing, and synthesizing findings from academic papers using language models trained to understand scientific content. Researchers can upload their own papers, ask research questions, and get structured summaries across hundreds of papers in minutes rather than weeks. Scientists, academics, and policy researchers use Elicit to accelerate systematic reviews, meta-analyses, and evidence-based decision making.
