## Chunk: AI Notebook & Research

Chunk positions itself as a second brain that is switched on: one AI workspace where your notes, PDFs, videos and research live together and where you can interrogate them in plain language. Rather than sending you to several different chat apps, it puts models from OpenAI, Anthropic and Google behind a single interface and lets you switch between them inside the same conversation.

The grounding layer is what separates it from a plain chatbot. Connected Chat answers from your own material and attaches a citation to each claim, so you can tap through to the note or page that produced it. Alongside chat there is a Markdown editor with wiki-style links and backlinks, automatic resurfacing of related notes, and an AI memory that personalizes answers while staying visible and editable.

The application is built for Apple hardware - iPhone, iPad, Mac and Apple Vision Pro - with continuous sync, and it deliberately spans several workflows: students converting lectures into flashcards, researchers producing cited reports with APA or MLA bibliographies, professionals asking questions across large document libraries, and anyone who wants recurring research delivered automatically. Chunk states that your data is never sold and never used to train models, and that everything can be exported.

**Pricing & Plans:** Freemium. A free plan covers everyday AI chat and core notebook use with no demo restrictions, and Chunk Pro unlocks all frontier models, unlimited deep research, larger-scale automations and the full document library; the yearly plan includes a free trial. In-app purchases available on the App Store.

- **Multiple frontier models in one app:** Chat with top-tier models from OpenAI, Anthropic and Google, and switch between them mid-conversation without losing context or opening a separate app.
- **Answers with citations:** Connected Chat quotes your notes, documents and saved pages, and each claim carries a tappable citation back to the original source.
- **Capture and organize anything:** Clip links, PDFs, screenshots and emails into an Inbox, then organize sources into Collections and ask questions across an entire project.
- **Videos and documents into study artifacts:** Turn YouTube videos, lectures, podcasts, webpages and PDFs into transcripts, summaries, flashcards, quizzes and concept maps.
- **Scheduled research automations:** Standing agents re-run research, watch pages and prices, and deliver cited digests on a schedule while you are away.

**Strengths:** Answers are traceable because every claim links back to your own sources; Model choice is flexible and you can switch mid-conversation instead of locking in; Runs natively across iPhone, iPad, Mac and Vision Pro with syncing; Combines note-taking, research, study tools and automations in one place

**Limitations:** Document uploads above roughly 500 pages can slow down or hit performance limits; Early reviews flagged buggy tags and occasionally non-persistent chats; Full power (unlimited deep research, automations, big library) sits behind 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
