AI academic search engine for peer-reviewed science
Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper.
A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence.
Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence.
Aggregate findings across many studies into structured summaries that map what is known and where the gaps are.
Turn PDFs into listenable multilingual audio summaries
Upload a PDF and get a condensed set of key points instead of a full-length read-through, so you capture the argument in minutes rather than hours.
Summaries are voiced in many languages with professional-sounding narration, making content usable for audiences that do not share a single language.
The end result is an audio digest you can listen to on the move, suitable for newsletters, class notes, briefings, and internal updates.
An API endpoint lets you convert PDFs to audio programmatically, so the same capability can sit inside your own app or content pipeline.
