## 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

## Semantic Scholar

Semantic Scholar was launched by the Allen Institute for AI as an attempt to solve a very specific problem: scientific output grows far faster than any individual researcher's ability to read it. Instead of matching literal keywords, the platform applies natural-language processing and graph analysis to figure out what a paper is actually about, who it builds on, and which citations inside it mattered — surfacing papers a keyword search would never rank highly.

The catalog spans more than 240 million publications from journals, conference proceedings, preprint servers and repositories, with records combining metadata, abstracts, references, citation counts and extracted entities such as methods, datasets and figures. On top of the core search experience sit features like one-sentence AI TLDRs, Semantic Reader (an augmented PDF reader that surfaces inline citations, definitions and figures while you read), author and venue pages, research feeds, and a Scholar's Hub for tracking the people and topics you care about.

Everything on the site is free to use, and a developer API gives researchers, students and engineers programmatic access to the same corpus — the API now supports paper search, better documentation and improved stability. Because it is a non-profit academic project rather than a commercial product, there is no paid tier: the value proposition is depth of coverage and semantic relevance, not premium features.

**Pricing & Plans:** Completely free. Semantic Scholar is operated as a non-profit academic project by the Allen Institute for AI, with no subscription tiers — accounts, search, Semantic Reader and the developer API are all available at no cost.

- **Semantic search across 240M+ papers:** Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
- **AI-generated TLDR summaries:** Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
- **Semantic Reader:** An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
- **Citation context and influence signals:** See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
- **Free developer API and Scholar's Hub:** A documented public API exposes search and metadata endpoints at no charge, while Scholar's Hub lets you follow authors, topics and citation alerts.

**Strengths:** Free to use with no paywall, subscription or credit limits; Very broad coverage spanning 240M+ papers in all scientific fields; Semantic ranking and AI TLDRs surface relevant work that keyword search misses; Semantic Reader adds inline citations, definitions and figures during reading

**Limitations:** Indexing lag means the newest preprints are not always immediately available; TLDR summaries are machine-generated and can oversimplify nuanced findings; Full text is frequently limited to what publishers or repositories expose; Not a citation manager: no built-in PDF library, BibTeX export workflow or note system
