The report card
Best for AI text and image detection
Winston AI detects AI-written text and images and adds plagiarism checks from Essential at $10 a month. The free account is a 14-day trial with 2,000 credits, not a plan that renews, and annual plans can't be cancelled during the term.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | $10 a month billed annually ($18 monthly) for Essential, close to the category's $9.75 middle. |
| Free plan and trial | C | A free account with 2,000 credits for 14 days, with no paid plan needed. It doesn't renew. |
| Features | B | AI text and image detection, plagiarism, OCR, reports and writing feedback. Nothing in the listing shows a gap in the core job. |
| Ease of use | C | No store rating on record. An account, credits and plan tiers to learn. |
| Platforms and integrations | B | Web and a browser extension, with Zapier, ChatGPT and an API. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Winston AI is for

- Works for small teams that can share credits on Advanced
Who it is not for
- Tight if you stay free: 2,000 credits for 14 days, with no plagiarism, OCR or PDF reports
- Not for you if you want to cancel mid-term, because annual plans can't be cancelled during the term
- Watch out: plagiarism checks start on Essential, not the free account
- Watch out: the page advertises a 50% coupon code, so list prices here may not match what you pay

Keep it
Nothing Winston AI does is plain enough to make in a weekend. The 5 things listed below take a company.
It costs $120 a year.
What you could not
- Grammar checking as you type, wherever you type.
- It plugs into other products, Zapier and ChatGPT among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
- Hooks into the device itself: handwriting.
- The depth: we grade its features B, which means it covers the whole job.
