Semantic Scholar is a free, non-commercial academic search engine built by the Allen Institute for AI (Ai2). It indexes more than 240 million papers from every field of science and uses machine learning to extract meaning from abstracts, citations, figures and tables, so researchers find relevant work faster than with keyword-only search.
Side Reader is a Chrome extension that opens PDFs in the sidebar of ChatGPT, Claude and DeepSeek so you can read and interact with them side by side: summarize, translate, explain or ask about any passage without leaving the chat.

Semantic Scholar is a free, non-commercial academic search engine built by the Allen Institute for AI (Ai2). It indexes more than 240 million papers from every field of science and uses machine learning to extract meaning from abstracts, citations, figures and tables, so researchers find relevant work faster than with keyword-only search.
Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
Side Reader is a Chrome extension that opens PDFs in the sidebar of ChatGPT, Claude and DeepSeek so you can read and interact with them side by side: summarize, translate, explain or ask about any passage without leaving the chat.
PDFs render directly in the sidebar next to the chat, so your document and the AI conversation are visible at the same time.
Summarize a whole document, translate it, or have passages explained in simpler terms using the AI you are already signed into.
Built-in buttons cover the common actions, and you can edit their prompts to make the AI respond in the format and tone you need.
Ask about charts, scans or regions that cannot be selected by taking a screenshot question instead.
