I used Cite This For Me, then ZoteroBib, before building Scholar Sidekick. This is the comparison I would have wanted then.
Cite This For Me, Citation Machine, and EasyBib are three Chegg-owned URL-paste citation generators that share a common shape. The free tier covers many CSL styles - APA, MLA, Chicago, IEEE, Vancouver, Harvard, and others - but the path from input to copyable citation goes through several click-throughs, a style picker that loads each style on demand, and frequent popup prompts to run a Chegg plagiarism check on your draft. Free-tier export is clipboard-only; downloading the citation as a Word .docx is Premium. All three are mature student-essay tools millions of people have used. For a one-off citation where you do not mind the friction or the upsell, any of them works.
Scholar Sidekick (scholar-sidekick.com) is free across all 10,000+ CSL styles at the anonymous tier - no signup, no Premium upsell, no plagiarism prompts, no click-throughs, no slow style menu. We start from the identifier (DOI, PMID, PMCID, ISBN, ISSN, arXiv, ADS bibcode, WHO IRIS URL) and resolve metadata live from authoritative registries (Crossref, PubMed, DataCite, OpenAlex). Free-tier export covers BibTeX, RIS, CSL-JSON, EndNote XML, RefWorks, NBIB, RDF, CSV, plain text, and Word-friendly HTML. The path from input to output is one paste and one copy.
I am writing this from years of personal Cite This For Me use. I used it for almost everything, then moved to ZoteroBib because the click-through friction kept getting heavier. Eventually I built Scholar Sidekick. The page below sets out what Cite This For Me does best, what Scholar Sidekick does best for paste-and-format users and for scripts and agents, and how to use them together when the in-browser bibliography is the right shape.
These tools are not competitors. Most readers who land here will keep using Cite This For Me for the in-browser bibliography workflow on URL inputs and reach for Scholar Sidekick when the friction in a Chegg-tier free generator becomes too much, or when a script, an agent, an identifier other than a DOI, or a retraction check is what is actually needed.

Cite This For Me is the right tool for a specific, large user segment: students writing essays who want a browser-based, URL-paste citation generator with a persistent in-browser bibliography and a Premium upgrade path that bundles plagiarism checking, grammar tools, and Word export. If your work involves any of the following, Cite This For Me (or a Chegg-bundled Premium subscription) is the right tool and Scholar Sidekick is not trying to compete:
Cite This For Me's free tier covers many CSL styles, but reaching the formatted citation is friction-heavy: a style menu that loads each style on demand, multiple click-throughs to add the citation to a bibliography, frequent popup prompts to run a Chegg plagiarism check on your draft. Free-tier export is clipboard-only; downloading as Word .docx requires Premium. For one-off citations where the friction is the bottleneck, or for any work outside the URL-paste essay case, Scholar Sidekick's anonymous tier is built differently. Concretely:
Cite This For Me has no public API for citation formatting. For any workflow that involves scripts, CI jobs, systematic-review automation, or AI agents handling references, the gap between Cite This For Me and Scholar Sidekick is total - this is not a feature comparison, it is a category that Cite This For Me does not occupy.
These tools solve different problems and work well in combination. The most common pattern is: keep Cite This For Me for the URL-paste in-browser bibliography workflow, reach for Scholar Sidekick for identifier-first tasks, friction-free single-citation copy, retraction checks, or any moment a script or agent needs to call the citation generator. A few concrete patterns:
Yes for the citation-formatting and identifier-resolution parts of the workflow. Both tools are free for the basic citation-generation use case, but they are different shapes. Cite This For Me is a free in-browser bibliography builder optimised for URL paste and student-essay workflows; Word .docx export, plagiarism checking, grammar tools, and ad removal are Premium. Scholar Sidekick is a free stateless API plus nine purpose-built free tools, optimised for identifier-first resolution, retraction-awareness, and agent integration; export formats including Word-friendly HTML and BibTeX are free at the anonymous tier. If you only subscribe to Cite This For Me Premium for Word export, Scholar Sidekick covers that case for free.
The style picker loads each CSL style on demand rather than from a pre-loaded set, which adds latency on every style switch. Combined with click-throughs to add the citation to a bibliography and frequent popup prompts to run a Chegg plagiarism check, the path from input to copyable citation is longer than the underlying work. For one-off citations where the friction is the bottleneck, Scholar Sidekick's anonymous tier renders any of the 10,000+ CSL styles instantly with no menu loading or popup prompts.
Both are Chegg-owned siblings of Cite This For Me, and all three share the URL-paste, in-browser bibliography, free-tier-then-Premium-upsell pattern. Citation Machine's free tier covers a broad style range, but reaching it currently requires clicking through several Premium prompts and interstitials before you reach output - roughly five clicks deep. EasyBib follows the same pattern: click through one check, then another, then finally get to the format selection. All three surface frequent popup prompts to run a Chegg plagiarism check on your draft - that is the broader Chegg-ecosystem upsell motion in action. The trade-offs across the three brands shift over time; what stays constant is the URL-first model, the friction layer, and the Chegg cross-product nudge.
Probably not, if you actively use Cite This For Me's in-browser bibliography for an essay workflow, the URL-paste auto-cite covers your inputs, and you have not subscribed to Premium. That free loop works well, and Scholar Sidekick is not trying to replace it. Reach for Scholar Sidekick when you need broader identifier coverage (PMCID, ADS, ISSN, WHO IRIS), retraction or open-access checks, an API or MCP server, deterministic transform versioning, friction-free single-citation copy, or free Word-friendly export - the moments Cite This For Me's free tier does not cover or makes you click through too much.
No. Cite This For Me is browser-first: the citation generator runs in the page, the bibliography is stored in browser local storage, and there is no public REST API for citation formatting. For any workflow that involves a script, a CI job, or an AI agent generating citations, Scholar Sidekick's /api/format endpoint or the first-party MCP server is the right tool.
No. Scholar Sidekick is stateless by design - we do not store your citations on our server or in your browser. If you want a persistent bibliography in the browser, Cite This For Me, MyBib, or Zotero are better fits. If you want stateless, scriptable, one-shot citation generation that produces the same output every time at a pinned transform version, Scholar Sidekick is the right fit.
No. Cite This For Me does not cross-reference Retraction Watch (retractions, corrections, expressions of concern) and does not classify open-access status (Gold, Green, Hybrid, Bronze). Scholar Sidekick provides both via dedicated tool pages: /tools/retraction-checker and /tools/open-access-checker. These currently live as standalone tools rather than being wired into the main /api/format resolver.
Cite Cite This For Me by URL (https://www.citethisforme.com) and the date you generated the citation. Cite Scholar Sidekick by URL (https://scholar-sidekick.com) and including the x-scholar-transform-version value from the response, which pins the formatter chain to a specific snapshot for reproducibility. The /verification page shows how to capture the value programmatically.
