## 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

## 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
