## 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

## Text Selected

Text Selected is a small, single-purpose Chrome extension. Its job is narrow and clear: you highlight text on a web page, pick the extension's option from the right-click context menu, and it returns a relevant answer without you having to open a new tab or search engine.

Under the hood the extension sends the selected text to a remote service, which looks through a JSON file hosted on Google Cloud Storage for the corresponding entry. The answer is shown in a simple browser alert, so the interaction stays inside the page you were already on. This makes it useful for quick reference lookups where the source data is already curated in the backing file rather than generated on demand.

Because answers come from a fixed dataset, what you get back depends on what the JSON file contains; it is not a general-purpose AI chatbot. The extension is free, published by an individual developer, version 2.0, and uses a Spanish (Latin America) interface, with a declared data policy covering user activity and website content.

**Pricing & Plans:** Free. The extension has no paid tier or subscription; you install it from the Chrome Web Store and use it at no cost.

- **Select text anywhere:** Works with any page: highlight a word or phrase and use the context menu to submit it.
- **Remote JSON lookup:** The selection is sent to a remote service that searches a JSON file for a corresponding answer.
- **Instant alert response:** Results appear immediately in a browser alert so you can read them without leaving the page.
- **Minimal footprint:** Small, focused add-on that does one job: fetch relevant information for the text you selected.

**Strengths:** Free with no account or subscription; Answers appear in a simple alert without leaving the current page; Works from the standard right-click context menu; Very small download (around 28 KB)

**Limitations:** Answers are limited to whatever is stored in the remote JSON file; Spanish (Latin America) interface only; Relies on a remote service, so it needs an internet connection; No ratings and a small user base
