Writesonic's AI Article Writer produces long-form pieces of “3,000 to 8,000 words” after analysing search results and competitor pages. The goal, in its own words, is “to rank on Google AND get cited in AI search”. Every paid plan bundles the writer with AI-visibility tracking and site audits. Those are tools for a brand's website, and nothing in them is aimed at a marked assignment.

Users notice the gap. One SoftwareReviews reviewer says it “isn't very good at writing academic essays/articles” and asks for a citation generator for fact checking. A review by NoGood, a growth-marketing agency that recommends a rival AI-visibility tool, calls the output uneven and generic without detailed prompts and its factual accuracy inconsistent.

Both tools pull from the web, but for different readers. Grammarly's Citation Finder flags a claim in your essay that needs support, suggests a web-based source, then formats and inserts the citation in APA, MLA or Chicago. It doesn't name the databases it searches, so open each source before you keep it.

Writesonic says “Every claim backed by a first-party source before publish”, drawing on a bank of sources that excludes competitor blogs and SEO-spam aggregators. Those sources are web pages picked for marketing articles, not scholarly papers, and its article writer page lists no academic citation styles. It doesn't cite from your own library or a scholarly database either.

Writesonic writes complete articles end to end; it calls the process “The Agentic Content Pipeline”. Point it at a topic and the whole piece is its work. Trustpilot reviewers praise the speed, while others call it overpriced next to general chatbots.

Grammarly mainly works on your own text, though it will also write: docs agents add new text on request, and AI Grader suggests AI rewrites that Grammarly itself says could get work flagged for AI use. Authorship helps here: it records whether text was typed, pasted or AI-assisted and gives you a replay and a report you decide whether to share.

This is where Grammarly has no competition from Writesonic. AI Grader takes your assignment details and rubric, estimates your grade and gives personalized feedback, and Reader Reactions points out where a reader could get confused. Treat the grade as a guide: Grammarly says it shouldn't be taken as your actual grade.

Writesonic's site audits check websites, and its listed features include nothing that reviews an essay draft. If you paste coursework into it, you're using a marketing tool for a job it doesn't advertise.

Writesonic is priced for businesses. Starter is $79 a month billed annually for 15 AI articles, Basic is $199 and Growth $399, and its pricing page doesn't show monthly-billed prices. There's no free plan listed, only a 7-day free trial with no credit card needed. On Trustpilot, charges after cancelling and refused refunds come up often, especially on annual plans.

Grammarly Pro is $144 a year (shown as $12 a month on the plans page) or $30 month to month, so a year of Pro costs less than two months of Writesonic Starter. Grammarly's free plan includes docs, Authorship and most agents, with daily limits on AI Grader, Citation Finder and Reader Reactions and 100 AI prompts a month.

Choose Grammarly if you're a student. It works on your own essay, estimates a grade against your rubric, suggests and formats citations, and its free plan is enough to try all of that before paying.

Choose Writesonic only if you also write SEO content for a brand and need long articles plus AI-visibility tracking. Try the 7-day trial first, and read the renewal terms before you commit to annual billing.

Students who want every citation drawn from sources they picked are who we make EthiWrite for. It cites only from the papers, PDFs and web pages in your Library, and its Examiner Mode flags unsupported claims without rewriting a word. It will not write paragraphs from a prompt, so it's the slower choice if what you want is a finished draft.

Can I use Writesonic for essays?

You can paste a prompt into it, but it isn't built for that. Its homepage and article writer page don't mention essays or students, its sources are web pages chosen for marketing articles, and it lists no academic citation styles.

Is Grammarly cheaper than Writesonic?

By a wide margin. Grammarly Pro is $144 a year; Writesonic Starter is $79 a month billed annually. Grammarly also has a free plan, and Writesonic offers only a 7-day trial.

Does Grammarly or Writesonic add academic citations?

Grammarly's Citation Finder suggests web-based sources and formats them in APA, MLA or Chicago. Writesonic says its articles cite first-party web sources, but it lists no academic citation styles and doesn't search a scholarly database.

Will Grammarly or Writesonic get my work flagged as AI?

Writesonic writes the whole article, so anything you submit from it is AI text. Grammarly warns that its own AI rewrite suggestions could get work flagged, and students on Reddit report high detector scores after only editing with it.
