I can compare it with Article Forge+WordAI and RYTR (Heavy User), if you invite me, usually I'm making work with 1k+ word articles (mostly), semi manually. I have tested copy.ai, nichesss, and content villain, and so far only RYTR can satisfy my work and my client and its has foreign language that 100% suit the need. The downside of RYTR only its takes longer time to create long form, so its kinda tiredsome if you have to makes dozens articles on daily basis (maybe this is where Jarvis win but Jarvis don't have the language i need).
