## Recall

Recall turns scattered bookmarks, half-finished articles and long YouTube videos into one searchable, connected library. You save a link, a PDF or a note in one click and Recall pulls the transcript or text, writes a summary you can read or listen to, and files it with smart tags that grow more accurate as your collection grows.

The distinctive part is how Recall treats the models underneath. Instead of locking you into a single provider, it lets you bring ChatGPT, Claude, Gemini, Grok or DeepSeek and chat against your saved sources, so answers are grounded in material you actually chose rather than the open web. Related ideas across different items get linked automatically, and a knowledge graph view shows how topics overlap, while a built-in memory assistant resurfaces the right item while you browse.

Recall also leans into learning rather than just storage. Automatic quizzes on a spaced-repetition schedule convert your library into an active-recall practice loop, which is why students, analysts and researchers use it as a second brain. It runs on web and desktop and is free to start, with paid tiers that lift limits and add power features.

**Pricing & Plans:** Free to start with no account required for some summarizer tools; paid subscription tiers unlock higher limits and advanced features. Check the website for current plan details.

- **One-click saving:** Capture YouTube videos, podcasts, PDFs, articles, blog posts and personal notes from the browser, desktop app or mobile without copying text by hand.
- **Instant summaries:** Long-form sources are condensed into short readable or listenable summaries, with timestamped key moments for video and audio content.
- **Chat with your own sources:** Ask questions against your saved library using ChatGPT, Claude, Gemini, Grok, DeepSeek or other supported models, so answers stay grounded in your material.
- **Automatic connections and graph:** Related ideas across items are linked automatically and mapped in a knowledge graph so you can follow a topic from one source to the next.
- **Spaced-repetition quizzes:** Recall generates quizzes from your own content on a personalized schedule, turning saved material into long-term memory.

**Strengths:** Keeps all saved content in one searchable place instead of scattered bookmarks and chats; Lets you choose among major LLM providers rather than locking you into one; Summaries, transcripts and timestamps make long videos and podcasts quickly usable; Quiz and spaced-repetition features push knowledge into memory, not just storage

**Limitations:** Best experience requires a paid subscription once free limits are reached; Automatic tagging and linking are helpful but still need periodic manual cleanup; Some advanced capabilities depend on third-party model availability and quotas

## 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
