## HoverNotes

HoverNotes positions itself as the AI note taker that actually watches the video rather than only reading the captions. As you play a lecture, tutorial or course lesson, the extension captures on-screen content — code snippets, equations, slides and diagrams — and turns it into clean, structured Markdown with headings, bullet points and timestamped references. A one-click screenshot tool drops the current frame straight into your notes, which is useful for demo walkthroughs and visual subjects.

The extension works on essentially any site where video plays: YouTube, Udemy, Coursera, LinkedIn Learning, Skillshare, edX, Khan Academy, Vimeo, TED, Bilibili and university platforms such as Canvas, Blackboard, Moodle, Panopto and Kaltura, plus local video files. Because notes are stored as plain Markdown on your device, Obsidian users can point HoverNotes at their vault and keep everything local and searchable. Extra features include a distraction-free split workspace that dims the rest of the page, advanced playback controls from 0.1x to 16x speed, ad skipping on YouTube, and export to PDF or Word.

Beyond note taking, HoverNotes offers Live Translate, which translates a speaker's voice into your chosen language while keeping the picture in sync, and "Hovie," an in-note AI assistant that knows your notes, the transcript and your screenshots so it can explain a confusing moment or summarise a section. A generous free tier covers 20 minutes of AI notes with unlimited manual notes, while the Unlimited Pro plan removes the AI caps for regular learners.

**Pricing & Plans:** Freemium. The free Starter tier includes 20 minutes of AI Video Notes, 10 minutes of Live Translate, unlimited manual note taking, screenshots with timestamps, Obsidian integration and export to PDF or Word. Unlimited Pro is around US$18/month (about US$120/year, roughly US$10/month billed annually) and adds unlimited AI Notes, AI-chosen screenshots, transcript saving to your vault, AI Notes in 24 languages, custom prompts, unlimited Hovie chats and one hour of Live Translate per month.

- **Visual AI that watches the screen:** Captures code, equations, diagrams and slide content exactly as they appear, so notes are complete even on videos with no captions.
- **Structured Markdown notes:** Generates headings, bullets and syntax-highlighted code blocks that drop straight into an Obsidian vault or any Markdown editor.
- **Timestamped screenshots:** One click adds the current frame to your notes at the right timestamp, ideal for diagrams, demos and UI walkthroughs.
- **Live Translate and Hovie assistant:** 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.
- **Works on any video site:** From YouTube, Udemy and Coursera to university lecture systems and local files — if it plays in the browser, HoverNotes notes it.

**Strengths:** Captures on-screen code, equations and diagrams that transcript-only tools miss; Saves to Obsidian as local Markdown files for privacy and long-term ownership; Works across dozens of video platforms plus local files with no per-site setup; Free tier is genuinely usable for occasional note taking

**Limitations:** Requires the Chrome extension, so it is browser-bound rather than a standalone app; AI note minutes are capped on the free plan; heavy users need the Pro subscription

## SciSpace

SciSpace began as a typesetting and paper-formatting service called Typeset and has since grown into a broad AI research platform. Its core promise is that a researcher can move from finding a paper to understanding it to citing and writing about it without leaving one workspace. The platform indexes scholarly content from sources such as Google Scholar, PubMed and arXiv, and layers AI agents on top for reading, extracting data and synthesis.

The signature capability is conversational reading: you upload or open a PDF, then ask questions, highlight confusing sentences for plain-language explanation, or request structured summaries of methods, results and limitations. Around that sit task-specific tools — Literature Review, AI Writer, Paraphraser, Citation Generator, AI Detector, AI Humanizer, Extract Data and a Plagiarism Checker — plus a Chrome extension that adds the same assistant on top of publisher pages and a mobile app for reading on the go.

Access follows a freemium model: exploring and limited usage are free, while paid Premium, Advanced, Max and Enterprise plans raise model quality, credit limits and parallel agent capacity. The company is registered as PubGenius Inc. in Milpitas, California, and markets the product to individual researchers as well as universities and enterprises with SSO and admin controls.

**Pricing & Plans:** Freemium. A free tier with limited usage sits alongside paid Premium (~$12/month billed annually), Advanced (~$70/month) and Max (~$160/month) plans; monthly billing is higher. Enterprise pricing is custom. All plans advertise a 24-hour money-back guarantee, and annual billing carries a discount.

- **Chat with PDF:** Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
- **Literature Review and paper search:** Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
- **Writing, paraphrasing and citations:** An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
- **Extract Data and AI Detector:** Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
- **Chrome extension and mobile app:** Use the same assistant on top of publisher sites and PDF pages via the browser extension, or read and query papers from the mobile app.

**Strengths:** Combines paper discovery, reading, writing and citation tools in one place instead of five separate subscriptions; Conversational explanations of difficult passages are genuinely useful for non-native English readers and cross-disciplinary work; Covers widely used scholarly sources such as Google Scholar, PubMed and arXiv; Free tier plus a Chrome extension make it easy to evaluate before paying

**Limitations:** Credit-based limits can be confusing, and heavy users report hitting caps on the cheaper plans; Model access varies by tier, so the cheapest paid plan does not get the strongest reasoning models; AI-generated reviews and paraphrases still need careful human checking for accuracy and citation integrity
