## 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

## Claude

Claude is Anthropic's flagship AI assistant, renowned among software engineers, writers, and enterprise analysts for its natural prose, low hallucination rates, and sustained agentic execution. While the legacy directory slug still references 2023's 'Claude 2', both the Claude 2 and Claude 3/3.5/3.7 generations have been fully retired. As of late 2026, claude.ai runs on the Claude 5.5 generation—led by Claude Opus 5.5 (released September 2026), Claude Sonnet 5.5 for rapid everyday tasks and coding, and Claude Haiku 5.5—supporting up to a 1-million-token context window, 128K output tokens, and adaptive extended thinking.

Inside the web, desktop, and mobile apps, Claude functions as a full production workspace rather than a simple chat box. Users organize persistent knowledge bases with custom instructions in Projects, render and edit live React applications, SVGs, mermaid diagrams, and formatted slide decks side-by-side in Artifacts, and connect external SaaS tools via the open Model Context Protocol (MCP) and native web search. Paid subscribers also gain access to Claude Code—Anthropic's terminal and IDE agent capable of autonomous multi-file engineering across entire codebases—and Claude Cowork for collaborative enterprise task execution.

Anthropic structures Claude's 2026 pricing around compute capacity and team governance. The Free tier offers daily access to Sonnet 5.5, while Claude Pro ($20/month or $17/month billed annually) unlocks Opus 5.5, extended thinking, Projects, and entry-level Claude Code access. Heavy individual builders can upgrade to Claude Max at $100/month (5x Pro capacity) or $200/month (20x Pro capacity), while organizations can mix Team Standard seats ($20/seat/month annual) and Team Premium seats ($100/seat/month annual with 5x capacity and full Claude Code access) or adopt usage-based Enterprise contracts with audit logs and SCIM.

**Pricing & Plans:** Free tier ($0); Claude Pro at $20/mo ($17/mo billed annually at $200/yr); Claude Max at $100/mo (5x Pro usage) or $200/mo (20x Pro usage); Team Standard at $25/seat/mo ($20/mo annual) and Team Premium at $125/seat/mo ($100/mo annual); Enterprise from $20/seat/mo + API usage.

- **Claude 5.5 Model Family & Adaptive Thinking:** Combines frontier Claude Opus 5.5 and high-speed Sonnet 5.5 with configurable extended thinking, up to 1M-token context windows, and 128K-token outputs.
- **Claude Code & Claude Cowork Included on Paid Plans:** Pro, Max, and Team Premium plans bundle Claude Code for autonomous command-line software engineering, test execution, and repository-wide refactoring.
- **Interactive Artifacts & Document Generation:** Renders live interactive web apps, visualizations, spreadsheets, and formatted PowerPoint decks in a dedicated workspace panel alongside the chat.
- **Projects & Model Context Protocol (MCP):** Grounds conversations in shared project knowledge bases and connects directly to local filesystems, GitHub, Slack, and internal databases via MCP.
- **Constitutional AI Safety & Enterprise Governance:** Trained on Anthropic's updated 2026 Constitution with strict privacy guarantees, SSO, SCIM provisioning, and HIPAA-ready healthcare configurations.

**Strengths:** Top-tier coding, bug-fixing, and agentic planning performance powered by Claude Opus 5.5 and Sonnet 5.5; Natural, nuanced writing style that avoids the repetitive clichés common in competing LLMs; Claude Max ($100/mo 5x and $200/mo 20x) and mixed Team Standard/Premium seats provide clear scaling for heavy Claude Code users; Open Model Context Protocol (MCP) ecosystem enables deep, standardized connections to local tools and enterprise data

**Limitations:** No native photorealistic image or video generation inside claude.ai (limited to SVGs, code charts, and diagrams); Free tier does not include Claude Code and hits 5-hour rolling message limits quickly during long-context chats; Pro users ($20/mo) who rely heavily on Opus 5.5 or Claude Code can still exhaust their 5-hour rolling window and require Max ($100/mo)
