First Answer is a GEO and AEO platform that monitors how ChatGPT, Gemini, Claude, Copilot, Perplexity and Google AI Overviews talk about your brand. It tracks prompt visibility, position and sentiment, shows which sources AI cites, and recommends actions to win more space in AI answers.
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.

Define the prompts that matter to your business and track how ChatGPT, Gemini, Claude, Copilot, Perplexity, Grok and Google AI Overviews answer them over time.
See how often your brand appears versus competitors, where in the answer you are mentioned and how positively AI describes you.
Discover which domains, pages and publications the models reference in your category to find the content gaps worth filling.
Track which AI bots visit your site, how frequently and which pages they read, closing the loop between publishing and AI visibility.

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.
