## 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

## Semantic Scholar

Semantic Scholar was launched by the Allen Institute for AI as an attempt to solve a very specific problem: scientific output grows far faster than any individual researcher's ability to read it. Instead of matching literal keywords, the platform applies natural-language processing and graph analysis to figure out what a paper is actually about, who it builds on, and which citations inside it mattered — surfacing papers a keyword search would never rank highly.

The catalog spans more than 240 million publications from journals, conference proceedings, preprint servers and repositories, with records combining metadata, abstracts, references, citation counts and extracted entities such as methods, datasets and figures. On top of the core search experience sit features like one-sentence AI TLDRs, Semantic Reader (an augmented PDF reader that surfaces inline citations, definitions and figures while you read), author and venue pages, research feeds, and a Scholar's Hub for tracking the people and topics you care about.

Everything on the site is free to use, and a developer API gives researchers, students and engineers programmatic access to the same corpus — the API now supports paper search, better documentation and improved stability. Because it is a non-profit academic project rather than a commercial product, there is no paid tier: the value proposition is depth of coverage and semantic relevance, not premium features.

**Pricing & Plans:** Completely free. Semantic Scholar is operated as a non-profit academic project by the Allen Institute for AI, with no subscription tiers — accounts, search, Semantic Reader and the developer API are all available at no cost.

- **Semantic search across 240M+ papers:** Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
- **AI-generated TLDR summaries:** Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
- **Semantic Reader:** An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
- **Citation context and influence signals:** See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
- **Free developer API and Scholar's Hub:** A documented public API exposes search and metadata endpoints at no charge, while Scholar's Hub lets you follow authors, topics and citation alerts.

**Strengths:** Free to use with no paywall, subscription or credit limits; Very broad coverage spanning 240M+ papers in all scientific fields; Semantic ranking and AI TLDRs surface relevant work that keyword search misses; Semantic Reader adds inline citations, definitions and figures during reading

**Limitations:** Indexing lag means the newest preprints are not always immediately available; TLDR summaries are machine-generated and can oversimplify nuanced findings; Full text is frequently limited to what publishers or repositories expose; Not a citation manager: no built-in PDF library, BibTeX export workflow or note system
