Best for AI text and image detection

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.
What this rests on. Winston AI’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
