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.
Learn languages from Netflix, YouTube, and real-world texts with dual subtitles and AI
View your target language together with a translation, pause, replay single lines, and jump back to the previous subtitle with a hotkey.
Hover or click any subtitle word to see definitions, part of speech, and pronunciation without leaving the video.
Automatically saves looked-up words and phrases, then quizzes you with the original context to build durable recall.
Bring the same translation and lookup workflow to ebooks, PDFs, articles, and other web pages.
