Smodin vs Yomu AI: two essay writers, one with a library
Both will write your essay. Smodin's plans let you “write full essays with simple prompts”, and Yomu AI's new-document flow “writes a full, researched draft”. Their annual prices are nearly identical too. The differences are in what surrounds the draft.
Yomu AI is built as an academic editor: a source library, citations you can see coming from your own sources or its search, and feedback on your draft. Smodin is a broader toolkit, and part of it is a humanizer sold to get text past AI detectors. For a student, that tips it toward Yomu.

Writing assistants help you write; essay generators write the essay for you.
| Product | Type | Paid from | Free tier | Citations | Ghostwriting |
|---|---|---|---|---|---|
| Smodin | Essay generator | $12.99/month | Yes | Not verified | Writes the essay |
| Yomu AI | Writing assistant | $10/month | No | Your sources, or papers it finds for you | Writes the essay |
Two ways to write the whole thing
Smodin's AI Writer drafts essays, articles and research papers from a topic, with your choice of style, tone and length, and expands the next section when asked. Its writer FAQ says to “Always follow your institution's academic integrity policies when using AI writing tools.”
Yomu AI writes from a description of the paper, and its Document Assistant helps “write entire sections”. Yomu's ethics statement wants students to use it alongside their own writing, “not as a replacement for” it. Both, in other words, put the decision on you. If your course bans AI-generated text, neither is safe to lean on.
Citations and sources
Yomu cites from sources saved to your library, which you can reuse across documents, or from sources its Sourcely-powered search finds, in 700+ citation styles. You can also chat with PDFs, images and web search. A review based on public information liked the single workspace but warned that the citations still need checking against the sources.
Smodin says its writer can find sources and add references in APA or MLA in one click, and claims facts and statistics come out “100% accurate”. It doesn't say where the sources come from. Its users say generated references and facts need checking by hand, so treat each one as a lead, not a citation.
Matching prices, different limits
On annual billing the two line up almost exactly. Smodin Starter and Yomu Pro are both $10 a month. Smodin Premium is $16 and Yomu Ultra $17, and both of those remove the cap on writing. The caps below them differ: Yomu Pro allows 1,000 AI actions a month, while Smodin Starter's writing output is described only as limited.
Month to month, Smodin is cheaper: $12.99 and $19.99 against Yomu's $21 and $35. Smodin Premium also adds premium AI models, advanced humanization and a Chrome extension; Yomu's paid plans let you choose among models from several AI providers, with frontier models on Ultra.
Neither lists a free plan for its main product. Smodin lets you try its tools without signing up but doesn't publish the limits. Yomu's pricing FAQ says you can start for free to try the service, and it has separate free tools such as an essay outline generator and citation generators.
Feedback, or a way past the detector
On Yomu's side there's Get Feedback, added in September 2026: focused academic reviews of the draft that you preview, then apply. Read before you apply: an accepted suggestion becomes your text.
Smodin's bundle includes checks of a different kind: an AI content detector and a plagiarism checker. Next to them sits the humanizer, which its plans pitch as “Highest humanization possible to bypass Turnitin-level detection”. Submitting humanized text as your own is an academic-integrity risk, whatever a detector reports.
What reviewers report
Yomu has little independent coverage. Its only Trustpilot review complains that the subscription renewed without notice.
Smodin's reviews have a different problem. Its site shows a 4.8 out of 5 rating citing Trustpilot, but Trustpilot says Smodin's rating “is unavailable due to a breach of our guidelines” and that it removed fake reviews. Among the reviews that remain, the positive ones mostly praise its summaries and help with wording, and billing is the most common complaint: annual charges users didn't expect, and renewals they couldn't get refunded.
Which should you choose?
Choose Smodin if you want a cheap month-to-month toolkit, writer, summarizer, translator and plagiarism checker together, and you'll verify every reference it produces. Skip the humanizer for anything you submit.
Choose Yomu AI if you want an academic editor with a reusable source library, citation search in hundreds of styles and feedback you can apply, and you're ready to pay once you've tried it free.
Both of these will draft the essay if you ask. If you'd rather use a tool that can't, EthiWrite, which we make, won't write paragraphs from a prompt, and it cites only from sources in your Library. That makes it the slower choice when a deadline is close.
