Smodin AI detector

The detector is free on the web without an account. The FAQ says the tool "is available with no limits, and sign up to get even more insight into your AI detection score with sentence-by-sentence analysis", and the only published ceiling is the 50,000 characters per check (smodin.io/ai-content-detector, read 9 November 2026). No monthly word allowance is stated, so the card carries no free-words-per-month figure and the free tiers ranking lists it in the second table.

The pricing page sells two subscriptions, Starter and Premium, with a Monthly and Annual toggle labelled "Save 20%" (smodin.io/pricing, read 9 November 2026). The price cards render by script, so the figures below come from the page's own embedded product offer data, read the same day: Starter $12.99 a month or $10.00 a month billed annually, Premium $19.99 a month or $16.00 a month billed annually. The comparison table marks the AI Content Detector as Standard on Starter and Advanced on Premium, and gives Premium the Chrome extension, API access, bulk processing and 24/7 priority support.

Retention is stated as zero on the product page and left open in the legal pages. The detector page says "Your text is never stored or shared" above the text box and "Your content is encrypted and never stored" in its features, and the FAQ adds "We also never store your files" (smodin.io/ai-content-detector, read 9 November 2026). The card's retention rank field takes that clause as a stated zero, the handling the data retention ranking gives Undetectable AI. The privacy policy, last updated March 30, 2026, keeps personal information "when we have an ongoing legitimate business need to do so" and does not mention submitted text (smodin.io/legal, read 9 November 2026). The terms of service on the same page grant the vendor "a worldwide, non-exclusive, royalty-free, perpetual, irrevocable license to use, reproduce, modify, adapt, publish, translate, distribute, and display" User Content, a clause a reader should weigh against the "never stored" line.

The vendor states an accuracy rate of 99.8% in the page header, in a "How We Compare" table that puts competitors at "~85-95%", and in a stat block that pairs 99.8% with the words Accuracy Rate (smodin.io/ai-content-detector, read 9 November 2026). The FAQ splits the figure: "Smodin AI detector maintains 99% (accuracy) when analyzing human-written content. It maintains 99.8% (accuracy) for AI-generated content." The about page uses the same 99.8% as a satisfaction figure, "Users recommend Smodin" (smodin.io/about, read 9 November 2026).

The evidence the page offers for the number is a section titled "Accuracy in Action", which describes three checks: one passage written with ChatGPT that scored 100% machine-generated, one passage copied from a book that scored "100% human-written text with zero false positives", and one mixed text in which the ChatGPT portion was marked (smodin.io/ai-content-detector, read 9 November 2026). Three texts do not produce a rate, so the card records no false positive rate and the false positive ranking does not list Smodin.

The vendor's caveats are in the same page. The false positive section says "a detection result doesn't always mean an AI assistant generated the text" and that "brief, standardized, and mechanically polished" passages can be flagged; the best practices section says a flag "is a risk signal, and human contextual assessment is still required"; and a heading reads "Smodin AI Detector is a Tool, Not a Judge" (read 9 November 2026). The page also carries nine testimonials, several from students who describe using the detector to check that their own work will not be flagged, and a "Humanize AI text" link for revising flagged passages. The Premium plan on the pricing page promises "the highest humanization possible to bypass Turnitin-level detection" (smodin.io/pricing, read 9 November 2026). A detector and a bypass tool sold on one subscription is the caveat a reader should carry away.
