## 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

## SciSpace

SciSpace began as a typesetting and paper-formatting service called Typeset and has since grown into a broad AI research platform. Its core promise is that a researcher can move from finding a paper to understanding it to citing and writing about it without leaving one workspace. The platform indexes scholarly content from sources such as Google Scholar, PubMed and arXiv, and layers AI agents on top for reading, extracting data and synthesis.

The signature capability is conversational reading: you upload or open a PDF, then ask questions, highlight confusing sentences for plain-language explanation, or request structured summaries of methods, results and limitations. Around that sit task-specific tools — Literature Review, AI Writer, Paraphraser, Citation Generator, AI Detector, AI Humanizer, Extract Data and a Plagiarism Checker — plus a Chrome extension that adds the same assistant on top of publisher pages and a mobile app for reading on the go.

Access follows a freemium model: exploring and limited usage are free, while paid Premium, Advanced, Max and Enterprise plans raise model quality, credit limits and parallel agent capacity. The company is registered as PubGenius Inc. in Milpitas, California, and markets the product to individual researchers as well as universities and enterprises with SSO and admin controls.

**Pricing & Plans:** Freemium. A free tier with limited usage sits alongside paid Premium (~$12/month billed annually), Advanced (~$70/month) and Max (~$160/month) plans; monthly billing is higher. Enterprise pricing is custom. All plans advertise a 24-hour money-back guarantee, and annual billing carries a discount.

- **Chat with PDF:** Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
- **Literature Review and paper search:** Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
- **Writing, paraphrasing and citations:** An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
- **Extract Data and AI Detector:** Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
- **Chrome extension and mobile app:** Use the same assistant on top of publisher sites and PDF pages via the browser extension, or read and query papers from the mobile app.

**Strengths:** Combines paper discovery, reading, writing and citation tools in one place instead of five separate subscriptions; Conversational explanations of difficult passages are genuinely useful for non-native English readers and cross-disciplinary work; Covers widely used scholarly sources such as Google Scholar, PubMed and arXiv; Free tier plus a Chrome extension make it easy to evaluate before paying

**Limitations:** Credit-based limits can be confusing, and heavy users report hitting caps on the cheaper plans; Model access varies by tier, so the cheapest paid plan does not get the strongest reasoning models; AI-generated reviews and paraphrases still need careful human checking for accuracy and citation integrity
