Smodin

Smodin is a writing toolkit that combines AI detection, rewriting and plagiarism checking in one place. You paste or upload text and it reports an overall AI probability with sentence level highlights, rewrites passages that read as machine generated, and scans the same document against web and academic sources. It is built for students and professionals producing written work. The toolkit covers an AI content detector, a humanizer that rewrites text to read as human written, a plagiarism checker, an AI writer for essays and summaries, a text rewriter, a chat assistant for explaining topics and tutoring, a summarizer and a translator, with support for more than 100 languages. The upper tier adds extended chat memory, premium models, unlimited writing output, a Chrome extension, API access, bulk processing and custom templates. Two paid plans are published. With annual billing selected the page shows Starter at $10 USD per month and Premium at $16 USD per month; monthly billing is also offered, and the page states that annual billing saves 20 percent. Starter opens every tool with standard models and limited output, while Premium adds the premium models, unlimited output, the browser extension and priority support. A referral scheme credits $5 once an invited user has been subscribed for 30 days, capped at $10 of credit or one free month per calendar month. Be clear about what the product is positioned to do. Much of the marketing centers on producing work that passes AI detectors, so institutions with academic integrity policies may treat its use as a problem rather than a feature.
