AI that watches your video and writes study notes as you watch
Captures code, equations, diagrams and slide content exactly as they appear, so notes are complete even on videos with no captions.
Generates headings, bullets and syntax-highlighted code blocks that drop straight into an Obsidian vault or any Markdown editor.
One click adds the current frame to your notes at the right timestamp, ideal for diagrams, demos and UI walkthroughs.
Listen to a speaker in your own language while the video stays in sync, and ask Hovie to explain or summarise any moment using your notes and screenshots.
AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
