Free AI-powered academic search engine with 200M+ papers and citation graphs

Free📚Education & Research Launched November 2015 API Available Updated March 2026

What is Semantic Scholar?

Semantic Scholar is a free, AI-powered academic search engine developed by the Allen Institute for AI (AI2). It indexes over 200 million papers across all scientific disciplines and uses machine learning to help researchers find and understand the most relevant work in their field.

The platform's AI capabilities go well beyond basic keyword search. TLDR (Too Long; Didn't Read) provides one-sentence AI-generated summaries for millions of papers, allowing you to quickly scan results without opening each paper. The citation graph feature maps how papers cite and are cited by others, helping researchers trace the lineage of ideas and find seminal works. Semantic Reader offers an augmented reading experience with inline definitions, citation context, and skimmable highlights.

Influential citations are distinguished from perfunctory ones using machine learning, so you can see which papers actually built upon a cited work rather than just mentioning it. The Research Feed learns your interests over time and surfaces new relevant papers automatically. Semantic Scholar also provides paper recommendations, author profiles with h-index metrics, and research trend tracking.

The platform offers a robust free API used by thousands of developers and researchers for bibliometric analysis and research tool development. With its commitment to being permanently free and open, Semantic Scholar has become essential infrastructure for the global research community, serving millions of researchers monthly.

AI Patent Research — Search, Analyze & Draft Claims

Patent research used to require expensive attorneys for even basic prior art searches. AI changes the workflow dramatically: it can help you understand whether your invention is potentially patentable, search the conceptual landscape of prior art, break down existing patents into plain language, identify the key claims in a competitor's patents, and even draft initial patent claim language. This doesn't replace a patent attorney — it makes your time with one far more productive and focused.

Manage Citations and References with AI

Citation management is the unglamorous backbone of every research project — and doing it badly costs you hours of cleanup right when you have a deadline. AI tools can help you find sources, format citations correctly, identify which sources support specific claims, and catch inconsistencies in your reference list. This guide covers a practical workflow from finding sources all the way to generating a properly formatted bibliography.

Write a Literature Review with AI — Systematic and Comprehensive

A literature review is not a summary of papers you have read — it is a critical analysis of what the field knows, debates, and has left unresolved. The hardest parts are: finding the right papers, synthesizing dozens of sources into a coherent argument, and identifying genuine gaps versus gaps that only look like gaps because you missed something. AI helps with all three — especially the synthesis step, which takes most researchers weeks. This guide covers the full process from search strategy to final draft.

Write Your Thesis with AI — Research to Defense

Writing a thesis is one of the most demanding intellectual challenges of academic life. AI won't write your thesis for you — and it shouldn't — but it can dramatically reduce the time you spend on the mechanical parts: structuring arguments, drafting literature reviews, refining your writing, and preparing for defense questions. This guide shows you how to use AI at every stage of the thesis process while keeping your original thinking and academic integrity intact.
