## 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

## Elephas

Elephas is built for the kind of work that should never be pasted into a general chatbot: contracts, client files, policies, research notes and reports. Instead of uploading documents to a cloud service, you point Elephas at files or entire folders on your machine. It reads and indexes them locally, then lets you ask questions in everyday language. Every answer comes with a source reference, so you can open the quoted passage and check it against the original page, slide or sheet.

The privacy model is the core of the product. Documents, the search index and your chats stay on your computer in an encrypted database. When you ask a question, personal details such as names, emails and phone numbers are masked before the request leaves the device, and you can inspect exactly what was hidden under each answer. You also choose where answers are generated - the default Elephas gateway, your own API key for OpenAI, Claude or Gemini, or a local model that runs entirely on your machine with nothing sent anywhere.

Elephas supports documents in English, German, Spanish, French, Japanese and Chinese, with cross-language search, and ships as a macOS and Windows desktop app. A team tier lets an organisation put shared contracts and policies into a common Brain with role-based access, private per-person chats and end-to-end encrypted sync. Pricing is a 7-day free trial with no card required, followed by individual plans and a Teams option at $29 per person per month with no minimum team size.

**Pricing & Plans:** Free 7-day trial with no credit card required. After the trial, individual subscription plans apply, and Elephas Teams is priced at $29 per person per month with no minimum team size.

- **Local document indexing:** Files, folders, PDFs, Word documents, spreadsheets, slides and scans are read and indexed on your own computer rather than uploaded to a third-party service.
- **Answers with sources:** Every response cites the underlying file plus the page, slide or sheet it came from, so you can open and verify the passage yourself.
- **Personal detail masking:** Names, email addresses and phone numbers are hidden before a question leaves your device, and you can view exactly what was masked under each answer.
- **Choice of AI engine:** Use the default Elephas gateway, plug in your own OpenAI, Claude or Gemini API key, or download a local model so answers are generated on your computer with nothing sent.
- **Shared team Brains:** Invite teammates to a common Brain with manager, contributor or reader roles, keep individual chats private, and sync through end-to-end encryption.

**Strengths:** Documents, index and chats stay on your own machine in an encrypted local database; Every answer cites the exact file and page, making verification fast; You choose the AI backend, including fully local generation with nothing sent; Cross-language search across six languages without a language setting

**Limitations:** Desktop-only: there is no browser version, so you need macOS or Windows; Answers still travel to a cloud model unless you pick local generation, and cloud requests are not end-to-end encrypted; Automatic masking of personal details can miss things, so answers should still be reviewed
