Smodin puts an AI humanizer, an AI detector, a plagiarism checker, and rewriting tools in one place. Starter and Premium are the named paid cards, and the public cards do not show a subscription dollar amount.
Official website · smodin.io
Smodin fits a draft you already have and want to score, rewrite, or check against sources. The detector names ChatGPT, GPT, Claude, and Gemini and shows sentence highlights. It is a weaker fit if you need one paste minimum or a price on the card. The box says 300 character minimum, while the steps say at least 50-100 words. Starter and Premium differ on output limits and the Chrome extension, and the public cards leave the dollar amounts off the page. The 99.8% Accuracy label is the site's figure.
The detector box says paste text or upload (.txt,.doc,.docx,.pdf), with a 300 character minimum, and that your text is never stored or shared. A how-it-works block says to paste or upload your text and add at least 50-100 words you want to check for AI, including essays, emails, articles, or reports. It includes under 1s Speed and 99.8% Accuracy as labels. Run a Quick Scan by clicking Detect AI. The page says it analyzes writing patterns from models like ChatGPT, GPT, Claude, and Gemini, then shows AI vs human scores: overall probability, sentence-level highlights, and a verdict. Help asks whether text is saved.
Official documentationThe homepage says the humanizer will turn AI text into natural, human-sounding writing that passes leading AI detectors and keeps your voice. The plagiarism checker says it scans against billions of sources. Writer and chat are for brainstorming, outlining, and drafting. The footer also lists a rewriter, a summarizer, and a translator. The Premium card says humanization is aimed at Turnitin-level detection and that plagiarism scans cover web and academic sources. Starter gives you instant access to all tools, including essays from prompts and chat for homework. Those are plan sentences, not test results. Help says the rewriter, translator, or plagiarism checker can fail once, and that downtime of up to about one hour can occur before you contact support.
Official documentationThe pricing page shows Monthly and Annual, Save 20%, and Currency USD. Starter lists every AI tool with no locked features: detector, humanizer, plagiarism checker, writer, chat, and a career toolkit for cover letters and mock interviews. Premium lists premium models, unlimited writing output, extended chat memory, the Chrome extension in Google Docs, and unlimited mock interviews. The comparison columns are Starter and Premium. Writing output is Limited then Unlimited. Chat is Standard then Extended Memory. Support is Email then 24/7 Priority. API Access is a row, with Extended nearby, and the checkmarks are not spelled out. The FAQ says Starter gives you instant access to all tools, while Premium adds unlimited access, tutoring and translating chat, and the Chrome extension. Cancel, refund, billing-switch, and payment-method questions have no public answers.
Official documentationHelp says the account email is the one used at checkout, and that Forgot Password is the way to find it. To pay, visit the pricing page, select your plan and currency, then sign up or log in and complete payment. You can start right after. Switching currency means you cancel the current subscription and create a new one. A wrong-charge question is listed without an answer. Stuck tools: retry, allow downtime of up to about one hour, then email support with a screenshot. Browsers named are Chrome, Firefox, Safari, or Edge. The API page offers rewriting, plagiarism detection, and AI content removal, including a Rewrite and Recreate API and a checker that scans web pages and academic sources. It says support for 100+ languages and a simple RESTful API with documentation and code examples. The price view is not in this public text.
Official documentationStarts with the stricter of the two minimums. If the box demands a 300 character minimum, meet that. If you are following the steps, add at least 50-100 words. Paste the essay or upload the.docx or.pdf, then run Detect AI and read the overall probability plus the sentence highlights. Keep the source file. It does not treat 99.
A suggested second pass uses the humanizer only on text you are allowed to revise, then the plagiarism checker on the result. The homepage says the humanizer keeps your voice and passes leading detectors. Read that as the product's description. The checker is described as a scan against billions of sources, not as a citation you can skip. If the rewriter fails once, help says to retry and to allow downtime of up to about one hour. This suggested order is not evidence that another detector will agree.
A suggested writing session uses AI chat or the writer for an outline, then you replace the draft with your own sources. Starter's card includes essays, homework, summaries, and rewrites. Premium is the card that says unlimited writing output and extended chat memory, plus the Chrome extension in Google Docs. Before paying, look for a dollar amount. The public page shows Monthly, Annual, and Save 20%. Confirm that figure at checkout. The sequence is suggested.
Open the tool that matches the draft. The homepage groups humanizer, detector, plagiarism checker, and rewriting tools together.
Paste text or upload.txt,.doc,.docx, or.pdf. Honor the 300 character minimum if that box is showing, or 50-100 words if you are on the steps.
Run Detect AI for probability and sentence highlights, or use the humanizer and plagiarism checker on text you can edit.
Use the pricing page to see limited versus unlimited writing output and whether you need the Chrome extension. Confirm the dollar amount at checkout.
The public pricing cards name Starter and Premium under a Monthly and Annual toggle marked Save 20% and Currency USD. They do not show a dollar subscription price, so the amounts below are Not verified. A referral block is separate from the plan price: you earn $5 after 30 days, with a cap of Max $10 credit or 1 free month per calendar month, and the friend gets 50% off the first month or year.
All listed tools with limited writing output.

Save 20% is shown, but the public cards do not show the two dollar prices that percentage would connect. Cancel, refund, billing-switch, and payment-method questions have no public answers. API prices are not in this public text.
Choose Quillbot when the job is paraphrasing rather than an AI-score plus humanizer bundle.
Smodin's public pages center on a detector, a humanizer, a plagiarism checker, and plan limits for writing output. Quillbot is a separate writing product, and its prices are not restated.
Choose Grammarly when you want writing feedback across documents rather than Smodin's scan-and-rewrite flow.
Smodin documents paste-or-upload detection, sentence highlights, and Starter versus Premium output limits. Grammarly is a different writing product. Bundle copy about other tools is not its feature list.
The pricing page also offers a free month if you refer 3 people in a month, which is a credit, not a feature list. The public Starter and Premium cards do not describe what stays free after that wording.
SourceStarter gives you instant access to all tools. Premium adds unlimited access, no output limits, tutoring and translating chat, and the Chrome extension. The table marks writing output Limited versus Unlimited and support as Email versus 24/7 Priority.

NavHunt did not run Smodin, did not paste a draft, and did not buy Starter or Premium. Detector steps, plan names, and the missing card prices come from Smodin pages reviewed on 2026-10-06. User quotes and the 99.8% Accuracy label are the site's own figures, not NavHunt results. This description is based on Smodin's official materials reviewed on 2026-10-06.
One detector box asks for 300 characters. The steps ask for 50 to 100 words. The plan cards still omit a dollar price.
