## 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

## Consensus

Consensus works like a scholarly search engine supercharged by AI. Instead of returning a flat list of PDFs, you ask a natural-language research question and Consensus extracts claims from relevant papers, then shows you what the studies actually find. A Consensus Meter summarizes the weight of evidence for yes/no questions, so you can see at a glance whether scientists largely agree, disagree, or remain divided.

The platform indexes hundreds of millions of peer-reviewed papers spanning medicine, biology, psychology, economics and more. Answers link straight back to the source studies, and you can filter by study design, journal quality, sample size and publication year to separate stronger evidence from weaker signals. Features like Deep Search, Topic Synthesis and Skills let researchers build a working knowledge base over time rather than starting from scratch on every query.

Consensus is designed for researchers, clinicians, students and analysts who need trustworthy signals from the scientific record without drowning in irrelevant results. A free tier gives limited AI-powered searches each month, while paid plans unlock unlimited use, advanced filters and deeper synthesis.

**Pricing & Plans:** Freemium. A free tier offers a limited number of AI-powered searches per month; paid individual plans unlock unlimited searches and advanced research features, with discounted student pricing and team/enterprise options.

- **Evidence-grounded answers:** Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper.
- **Consensus Meter:** A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence.
- **Powerful filters:** Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence.
- **Topic synthesis and Deep Search:** Aggregate findings across many studies into structured summaries that map what is known and where the gaps are.
- **Research workspace:** Save papers, organize sources and build a persistent knowledge base for literature reviews and ongoing projects.

**Strengths:** Answers cite real peer-reviewed papers, so claims are verifiable; Consensus Meter makes it easy to gauge scientific agreement at a glance; Rich filters help separate high-quality evidence from weaker studies; Fast, clean interface designed around research workflows

**Limitations:** Free tier caps the number of AI-assisted searches per month; Coverage is strongest for STEM and health fields, lighter for some humanities topics; It guides you toward sources but is not a substitute for reading full papers
