This is almost exactly like Textio (https://textio.com), except "similarity of writing" is not always predictive of actual results.

Textio's data is based on how documents performed in the real world along metrics people care about.

Textio looks like a a great product, but IIUC its use case is very specific -- how can you make your job description more enticing and gender-neutral?

Toasted is meant to be more of a big tent product: you're not just working with men/women, but very specific groups of people (e.g., retirees and accountants) and you want to use language in the way that they're using it, which is helpful for things like writing ad copy as well.

How can you know your writing will be effective without actually looking at other writing that you know had positive outcomes?

I think IsItToasted might be confusing "how people talk" with "an effective way of communicating that yields the result you want".
