Comparison

Sidenote vs Scholarcy

Scholarcy turns a research paper into summary flashcards and pulls out its references, figures and tables. Sidenote lives in your browser side panel and answers questions about whatever you are reading, citing each claim back to the exact passage it came from.

Sidenote

Reads the page you already have open and cites every answer.

Scholarcy

Breaks academic papers into flashcards and extracts their references.

The short answer

Should you use Sidenote or Scholarcy?

Choose Sidenote if…

Choose Sidenote if you read across web pages, Google Docs, Notion, Confluence and SharePoint as well as PDFs, and you want every answer cited to the exact passage and checked against the source. It also chats conversationally and builds a jargon glossary.

Choose Scholarcy if…

Choose Scholarcy if your work is specifically academic papers and you want summary flashcards, automatic reference, figure and table extraction, and links out to the original open-access sources, plus a developer API to build on.

Both save you from wading through dense documents, both offer a free tier, and both take a source-traceable approach rather than opaque AI. The split is scope: Scholarcy is built around the research paper and its bibliography, while Sidenote rides along on whatever you have open and grounds every answer in a clickable citation.

Compiled July 2026 from Scholarcy's official site and current public sources. Scholarcy summaries are extractive and traceable to the source text, but it does not chat conversationally, does not scroll a live page to a cited passage, and has no built-in OCR for scanned PDFs; its reference, figure and table extraction and its developer API are genuine strengths Sidenote does not match. If anything here is out of date, tell us and we will fix it. The cross-document row is powered by Sidenote Collections.

The core difference

A summariser you feed papers to, or a reader that rides along.

Scholarcy is purpose-built for academic papers: hand it a PDF, DOCX or a journal URL, or point its extension at an open-access page, and it produces summary flashcards, pulls out the highlights, and extracts the references, figures and tables, linking references to open-access copies. Its summaries are extractive so you can trace claims back to the source text, and it exposes a developer API for teams that want to build on the extraction engine.

Sidenote sits in the browser side panel and works on whatever you are reading, whether that is a PDF, a web article, a Google Doc, or a private Notion, Confluence or SharePoint page, with no upload. Every answer is cited to the exact source passage; clicking a citation scrolls the live page to it and highlights it, and the server drops any quote it cannot ground in the document.

A concrete example

You are reading a dense methods paper in your browser. Scholarcy turns it into flashcards and a reference list you can export to Word, Excel, RIS or .bib. Sidenote lets you ask a follow-up question in the side panel and jumps you to the exact sentence in the paper that backs its answer, then defines the jargon in one click.

Giving credit

Where Scholarcy is the better tool.

Scholarcy has been refining academic-paper summarisation for years, and it does several things Sidenote does not attempt. Credit where it is due.

Reference, figure & table extraction

Scholarcy pulls the citations, figures and tables out of a paper and links references to open-access copies on repositories like arXiv, which is genuinely useful for literature work.

Flashcards & study workflow

Its summary flashcards, literature matrices and one-click bibliographies, with export to Word, Excel, RIS and .bib, suit students and researchers building a review.

A real developer API

Scholarcy exposes public reference-extraction, knowledge-extraction and summariser APIs, so teams can build the engine into their own tools, which Sidenote does not offer.

FAQ

Sidenote vs Scholarcy — common questions

If you want to read and question documents in place and get answers cited to the exact passage, yes. Sidenote works across PDFs, web pages, Google Docs, Notion, Confluence and SharePoint from the browser side panel. If your need is specifically flashcards and reference extraction from academic papers, Scholarcy is the more specialised tool.
Scholarcy is built around the research paper: it summarises it into flashcards and extracts its bibliography. Sidenote is a general reader that chats with any open document and grounds every claim in a clickable citation that scrolls and highlights the source on the live page.
Yes. Scholarcy offers a browser extension for Chrome, Edge and Firefox plus a web app, and a free Article Summarizer that allows up to 10 summaries a month. Paid Scholarcy Plus is around GBP or USD 10 per month, with a 7-day trial that needs no card. Sidenote is also freemium with a free tier and a 7-day Pro trial that needs no card, and paid plans from GBP 10 a month.
Not in the same way. Scholarcy produces extractive summary flashcards and highlights rather than a conversational chat, and it does not scroll a live web page to a cited passage. Sidenote is built around back-and-forth questions with citations that jump to the exact source text.
Neither ships a native mobile app. Scholarcy is a web app plus a browser extension, and Sidenote is a desktop browser side-panel extension with a companion web app. Both are best on the desktop.
Scholarcy has the edge for pulling references and figures out of many papers and building a literature matrix or bibliography. Sidenote is stronger when you want to ask one question across a Collection of documents and get per-document citations you can verify.
