Winston AI pricing — common questions
Winston AI Pricing 2026: How It Works
Our Winston AI detector runs on a simple two-tier model: a free unlimited basic scan, and a full report available from $2 for a week. There’s no credit system, no per-word charges, and no trial period that expires before you’ve had a chance to actually use the tool.
What the free tier includes
The free scan gives you an AI probability score and a sentence-level preview in under 6 seconds, with no registration and no word limits. It covers detection across GPT-4o, Claude, Google Gemini, LLaMA, and other major language models. For a one-time self-check before submitting an essay, or an occasional check on your own writing, this is usually all you need.
What the full report adds
The full report unlocks the complete sentence-level breakdown, a plagiarism check, AI image detection, and a downloadable PDF — useful when you need to share results with an instructor, editor, or client. Pricing starts at $2 for 7 days of full access with no recurring charge, or from $7.99/month on the annual plan for regular use.
Who should upgrade
Teams, agencies, and educators who check content regularly get the most value from a paid plan — the PDF reports and plagiarism checking save time across repeated use. For individual students, freelance writers, and occasional users, the free detector already covers the core need: a fast, reliable AI probability score with no cost and no commitment.
Monthly vs annual billing
The Monthly plan is $19.99/month and can be cancelled anytime, taking effect at the end of the billing cycle — a good fit if your usage varies month to month. The Annual plan drops the effective rate to $7.99/month but is billed once per year and can’t be cancelled mid-term, so it makes the most sense if you know you’ll be checking content consistently throughout the year. If you only need a one-time check, the 7-day access plan at $2/week avoids any ongoing commitment entirely.
