Winston AI

Winston AI checks text and images for signs of AI. It is an AI content detector and plagiarism checker that scans documents, pictures and handwriting (through OCR) and can produce shareable PDF reports.

Image and deepfake detection sits alongside the text checker, and paid plans add writing feedback.

You can start on the free plan, which gives 2,000 credits over a 14 day trial.

Paid plans are credit-based: Essential has 80,000 credits a month, Advanced has 200,000, and Elite has 500,000.

Monthly prices run $12, $19 and $32, with lower rates on annual billing.

Team access grows with the tier, from invited members on Essential to up to 5 on Advanced and unlimited on Elite.

Winston AI also offers HUMN-1 website certification, with HUMN-1+ on Elite.

Credits can be topped up when you run out.
