## ExplainTXT

ExplainTXT turns any web page into something you can interrogate. After installing the Chrome extension, a single shortcut (⌘⇧E on Mac, Ctrl+Shift+E on Windows) reads whatever is in front of you. With nothing selected it summarizes the entire page — one line on what it is, followed by the key points. With text highlighted it explains just that passage in plain words and opens a sidebar where you can keep asking follow-up questions.

The workflow is designed to keep you in the text rather than bouncing to another tab or chatbot. Long articles, dense documentation, contracts full of legalese, forum threads and emails all become easier to skim. You can trigger it from the keyboard, from a highlight context menu, or from the toolbar icon, and the shortcut can be rebound at any time in Chrome. A dashboard on explaintxt.com lets you choose your language and text size.

The extension is free to install and monetized through in-app purchases, and the developer notes that mobile browsers do not yet support extensions. The Chrome listing reports version 4.4.0, a 4.2 rating and a few hundred users, positioning ExplainTXT as a lightweight utility for students, researchers, professionals and anyone who reads a lot of dense material online.

**Pricing & Plans:** Free to install with in-app purchases (freemium model). The developer does not publish fixed subscription tiers on the site; payments happen through the Chrome extension's in-app purchase flow.

- **One-shortcut page summaries:** Press ⌘⇧E (Ctrl+Shift+E on Windows) with nothing selected to get a concise summary of the whole page, led by a one-line gist and then the key points.
- **Highlight-to-explain:** Select any term, clause or paragraph and ExplainTXT explains just that part in plain language, right where you are reading.
- **Sidebar follow-up chat:** Answers open in a sidebar so you can ask additional questions about the page without leaving it or opening a separate chatbot tab.
- **Flexible triggers:** Run it from the keyboard shortcut, a highlight context menu, the toolbar icon, or an alternate ⌘⇧S shortcut, and rebind the keys in Chrome.
- **Language and text-size controls:** A dashboard on explaintxt.com lets you set your preferred explanation language and reading text size.

**Strengths:** Zero-friction workflow: one shortcut works on any website without copying text; Sidebar answers keep you in context and allow follow-up questions; Keyboard, mouse and toolbar triggers with rebindable shortcuts; Works across articles, docs, contracts, emails and forums

**Limitations:** No mobile support yet, since mobile browsers do not run extensions; Currency of full feature set depends on the extension, so the website itself is thin; Fixed pricing tiers are not published, only in-app purchases

## 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
