What Smodin does

• AI Content Detector: estimates how much of a text looks AI-written, with a sentence-by-sentence breakdown, across 100+ languages. Smodin says a score is a risk signal, not proof.
• Plagiarism Checker: scans your work against web and academic sources.
• AI Writer and AI Chat: drafts essays, summaries and rewrites, and explains topics like a tutor.
• AI Humanizer and Rewriter: rewrites text so it reads more naturally.
• Extras: summarizer, translator, a career toolkit with mock interviews, and a Chrome extension on Premium.

Is Smodin free? Not as a plan. The pricing page lists only Starter and Premium. Smodin’s homepage says you can paste, scan and try the tools without signing up, so you can test the detector before paying. Writing output on Starter is labelled limited.

Students mainly worried about AI flags should read our guide to free Turnitin-style AI detectors and our test of whether Turnitin detects ChatGPT. For citations and proofreading, Scribbr is the more academic option.

Who Smodin is for

Students and freelance writers who want detection, plagiarism checks and drafting in one subscription for less than most single-purpose tools. Teachers can use the detector, but should treat any AI score as a starting point for a conversation, not a verdict.

Limitations

• No free plan listed: only no-sign-up trials on the tools themselves.
• Detector accuracy claims are Smodin’s own: its 99.8% figure comes from its own tests. No AI detector is reliable enough to prove misconduct.
• Humanizers raise integrity questions: Smodin markets bypassing detectors. Using that to pass off AI writing as your own can break your school’s rules.
• Starter output is limited: unlimited writing is a Premium feature.

Smodin is a practical all-in-one writing kit for students, and the plagiarism checker plus detector combo is good value on Starter.

Use it to check and improve your own work. Don’t rely on its detector to accuse anyone, and don’t use the humanizer to hide AI writing your school doesn’t allow.
