## Dewey

Dewey solves a very specific and recurring problem in academic reading: you have found one good paper and now want the others that are conceptually close to it. Instead of reformulating queries by hand across a search engine or bibliographic database, Dewey reads the paper page you are currently on and returns a set of related papers, ranked by semantic similarity rather than keyword overlap.

The extension is deliberately small — the Chrome Web Store listing reports a package of roughly 14 KB — and the entire intelligence sits behind the Exa API, an AI-native search engine built for embeddings-style retrieval over web and document content. That architecture is why Dewey can act on any paper page you land on, not just ones hosted in a single database.

Dewey is free, has no advertisements, and the developer discloses that no user data is collected or sold. It is a good fit for graduate students, systematic-review authors, and anyone who routinely jumps between Google Scholar, publisher pages, and preprint servers and wants a faster way to expand a reading list.

**Pricing & Plans:** Completely free. The Chrome Web Store listing states Dewey is free with no ads, and no paid tier is advertised.

- **One-click similar-paper search:** Press the extension on any research paper page and get a ranked list of conceptually related papers without retyping queries.
- **Semantic matching via Exa:** Results come from the Exa AI search engine, which ranks by meaning and context rather than exact keyword matches.
- **Works on any paper page:** Because retrieval runs through the Exa API, Dewey is not locked to a single repository and can act on publisher pages, preprint sites, and personal pages.
- **Zero-ads, lightweight build:** The extension ships as a very small package and shows no advertising, keeping page load and interface overhead minimal.
- **Privacy-conscious defaults:** The developer declares no data collection, no sale of data to third parties, and no unrelated use of browsing data.

**Strengths:** Completely free with no advertising; Extremely lightweight install (small package, minimal footprint); Semantic similarity produces better neighbours than keyword search; Works across publishers and preprint servers, not one walled database

**Limitations:** Depends entirely on the Exa API, so quality tracks that service; No saved libraries, annotations, or export features; Last listed update was mid-2024, so the project moves slowly

## ExplainPaper

ExplainPaper takes the friction out of reading academic literature. Instead of parsing equations, acronyms, and field-specific jargon alone, you upload a PDF and highlight whatever you don't understand. The tool returns a short, contextual explanation of that passage, and you can dial the complexity up or down to match whether you're a newcomer to the field or an expert skimming for detail.

The explanations are context-aware: the model reads the surrounding paper so a highlighted term is explained in the sense the authors actually meant, not in a generic dictionary sense. You can request answers in more than 50 languages, which makes English-language research accessible to readers worldwide. Beyond highlights, a chat mode lets you ask follow-up questions about the paper and get answers drawn from the document itself, with pointers back to the relevant sections.

ExplainPaper also extracts structure for you. It can produce a smart outline, pull out the key findings and main arguments, and show how concepts in the paper connect. The service is used by a large community of researchers and is offered free with usage limits, with a paid Pro tier that unlocks stronger models, whole-paper summaries, and saved highlights.

**Pricing & Plans:** Freemium. The free tier costs $0 and includes unlimited highlight explanations, follow-up questions, and access to basic AI models. Pro is listed at $16/month and adds explanations powered by a more advanced model, whole-paper summaries, saved highlights and explanations, and paper Q&A, after a 7-day Pro trial that requires a card on file. Confirm current pricing on the provider's pricing page.

- **In-context highlight explanations:** Select any confusing sentence or term and receive an immediate plain-language explanation that accounts for the rest of the paper.
- **Adjustable explanation depth:** Shift the reading level from beginner-friendly to expert-detail so the explanation matches your background.
- **Chat with your paper:** Ask questions and get answers grounded in the document's actual content, with references back to the relevant sections.
- **Auto-generated insights:** Produce a smart outline, key-point extraction, and concept relationship views without reading the entire paper first.
- **50+ explanation languages:** Get explanations in your native language, making English-language research easier for a global audience.

**Strengths:** Explains passages in the context of the whole paper rather than in isolation; Reading-level control makes the same tool useful for novices and experts; Chat mode is grounded in the document, reducing generic or off-topic answers; Supports 50+ explanation languages for global readers

**Limitations:** Free tier is capped, and the strongest models sit behind the Pro plan; Pro trial requires a payment card up front; Not a substitute for careful reading of methods and statistics in high-stakes work
