What is Smodin?
Smodin bundles the writing-adjacent tools people usually juggle separately - an AI writer for essays, articles, and emails, a humanizer that rewrites AI text to lower detector scores, an AI content detector that flags likely AI-generated passages, and a plagiarism checker - into one platform and a Chrome extension that works inside Gmail, Google Docs, and Notion.
Key features
- AI Writer for essays, articles, emails, and research papers in 12+ languages
- AI Humanizer to rewrite text and lower AI-detector scores
- AI Content Detector that analyzes writing patterns from GPT, Claude, and Gemini-style output
- Plagiarism checker alongside the detector in the same workflow
- Chrome extension usable directly inside Gmail, Google Docs, and Notion
- Text rewriter/paraphraser as a separate standalone tool
How to get started
- Try the writer, detector, or humanizer free on smodin.io without signing up
- Paste or upload a document (.txt, .doc, .docx, .pdf)
- Run the AI Content Detector, then Humanize if it flags AI patterns
- Use the Chrome extension to run the same tools inside Gmail or Google Docs
- Subscribe to Starter or Premium once you need unlimited output
Smodin pricing
Smodin has no free subscription, but every tool can be tried without signing up. Starter unlocks all tools at standard quality with a limited output cap; Premium adds unlimited output, premium models, the Chrome extension, and priority support.
| Plan | Price | Best for |
|---|---|---|
| Starter | $12.99/mo ($10/mo annual) | Occasional use of all tools at standard quality |
| Premium | $19.99/mo ($16/mo annual) | Unlimited output, Chrome extension, priority support |
Our take: The value here is consolidation - if you are already paying for a separate detector, humanizer, and paraphraser, this replaces all three for less than two subscriptions.
