Our verdict

Castly turns a conversation with its AI, or questions asked of an uploaded document, into content refined inside a built-in text editor and then published directly. The free plan caps things at five PDF uploads and five published posts, while the $12-a-month plan removes those caps and adds unlimited uploads. Bloggers and learners who like drafting through conversation rather than a blank page fit well, though anyone publishing often will outgrow the free tier fast.
