Questions
HoverNotes vs Knowt — common questions
Is HoverNotes better than Knowt?+
It depends on what you need. For capturing notes while you actually watch a video, HoverNotes is purpose-built: it follows any video in your browser in real time, captures timestamped screenshots of on-screen code, equations and diagrams, and saves AI study notes to your Obsidian vault. Knowt is the stronger choice if you want a free flashcard and test-prep system — unlimited learn mode, spaced repetition, practice tests and AI quizzes from your materials.
What is the difference between HoverNotes and Knowt?+
Knowt is a free study platform built around flashcards and exams: it imports or generates flashcards, runs learn mode, spaced repetition and practice tests, and has Kai, an AI tutor. HoverNotes watches the video with you in real time, captures timestamped screenshots of the code and diagrams the moment they appear, and writes AI study notes straight to a local Obsidian vault.
Does Knowt capture on-screen code and diagrams from videos?+
Knowt can summarize a YouTube video or lecture recording into notes and flashcards from its transcript, but it doesn't watch alongside you or capture the visual frames — so the on-screen code, equations and diagrams aren't saved as images. HoverNotes follows the video as it plays and grabs exactly those moments as timestamped screenshots, which is what makes it strong for coding tutorials and diagram-heavy lectures.
Is HoverNotes cheaper than Knowt?+
Knowt has a generous free plan and a paid Ultra plan at about $12.49/month billed annually for unlimited AI features. HoverNotes is also free to install, with paid plans for heavier use. The bigger difference is what each does: Knowt is a cloud flashcard and test-prep library, while HoverNotes is local-first and captures screenshot-rich notes from video as you watch, saved to your own Obsidian vault.
Who should use Knowt instead of HoverNotes?+
Choose Knowt if your main need is flashcards and exam prep — a free Quizlet alternative with unlimited learn mode, spaced repetition, practice tests, AI-generated quizzes and a huge shared library for AP and class material. Choose HoverNotes if you learn from video and want notes and screenshots captured automatically as you watch, saved to your own vault.
