iLang Detect is free, requires no signup, and gives you a list of sentence-level issues across six dimensions plus a probability score. It also offers fix suggestions for every flagged fragment. Winston AI is a freemium tool aimed at educators, SEO teams, and publishers, with features like plagiarism checking, deepfake detection, and team management. Both tools detect AI text, but they serve different purposes. Which one should you use? That depends on whether you want to fix the writing or just verify it.

Where they differ
Pricing and Access
iLang is completely free with no signup required, and there is no rate limit. You can use it as much as you want. Winston AI offers a 14-day free trial with 2,000 credits, then paid plans start at $18 per month or $120 per year. For a casual user, iLang's pricing is much more accessible. But if you need ongoing checks for a team, Winston AI's subscription might make sense.
Output and Suggestions
iLang gives you a detailed list of issues across vocabulary, structure, tone, punctuation, logic, and rhythm. Each flagged fragment includes a problem explanation and a fix suggestion, plus overall rewrite advice. Winston AI provides an AI probability score and shareable PDF reports with sentence-level highlighting, but it does not offer any suggestions to improve the text. If you want to edit and revise, iLang is more helpful.
Features and Accuracy
Winston AI includes a plagiarism checker, AI image and deepfake detection, OCR for documents, and team seats for up to unlimited users. It claims 99.98% accuracy on its homepage, but independent reviews report real-world false positives around 8-10% and blind spots with Claude-generated text. iLang focuses solely on AI detection with detailed analysis, but it does not make a specific accuracy claim.
Which one to pick
For educators and content teams who need plagiarism checks and team collaboration.
Winston AI offers a broader suite: AI detection, plagiarism, deepfake detection, and OCR. It's built for institutional use with shareable PDF reports and team seats. If you need to verify originality and manage multiple users, Winston AI is the better fit.
For writers and editors who want to fix their text, not just get a score.
iLang goes beyond detection by highlighting specific issues in vocabulary, structure, tone, and more. Every flagged fragment includes a problem explanation and a fix suggestion. It's free with no signup, making it ideal for anyone who wants to improve their writing.
When you need both verification and editing, use them together.
Use Winston AI to get a broad check including plagiarism and deepfake detection, then use iLang to get detailed suggestions for improving the text. This combination covers both verification and revision.
