## ExplainThis

ExplainThis is an AI assistant aimed squarely at people who read for a living. It is distributed mainly as a Chrome extension, so instead of copying text into a separate tool you can summarise and explain a page right where you found it. That low-friction placement is the point: the tool is meant to slot into an existing browsing habit rather than demand a new workflow.

Its core jobs are summarisation and explanation. Long articles can be distilled into the essentials, and YouTube videos can be turned into the key points without watching start to finish. For startup knowledge workers — founders, marketers, salespeople and product managers — that means faster grounding when researching a market, a competitor or a topic that just came up in a meeting.

The product fits a category of lightweight AI copilots that augment browsing rather than replace it. It will not do your thinking for you, and summaries should still be checked against the source for anything high-stakes, but it removes a meaningful amount of reading overhead from the day. Check the official site for the current feature set and plan limits, since AI assistant products in this space evolve quickly.

**Pricing & Plans:** ExplainThis is generally offered as a free-to-start AI assistant with paid options for heavier usage. Review the official site for current pricing, as details may change.

- **Page and article summarisation:** Turn long articles and pages into a readable summary so you can decide what deserves a full read.
- **Video explanation:** Get the key takeaways from YouTube videos without sitting through the entire runtime.
- **Browser extension workflow:** Primarily a Chrome extension, so it sits alongside whatever you are already browsing rather than forcing a separate app.
- **Built for fast-moving teams:** Built for startup knowledge workers who need context fast across marketing, sales and product research.
- **Explanations on demand:** Ask follow-up questions about the content you are viewing to dig into the parts that matter to you.

**Strengths:** Sits inside the browser as a Chrome extension, so there is nothing new to launch; Handles both web pages and YouTube videos; Speeds up research for founders, marketers and product teams; Useful for triaging which long articles actually deserve a full read

**Limitations:** Relies on a browser extension, so it is most useful inside desktop Chrome; Summary quality depends on how well the page is structured; You need to review AI output before acting on it for anything important; Best experience requires signing in, which some users prefer to avoid

## 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
