I've tried ArticleForge and SEO Content Machine in the past and here are my experiences with them
ArticleForge
- expensive... $300+ per year is too much for a simple content generator
- bad support... they have manually terminated my trial account, because I gave them negative feedback after 3 articles that I have generated, in 3 different niches, have said something like "you will get cancer and die" (not the exact phrasing, but the exact idea)
- produces decent content for a software... the content still needs human interaction (grammar fixing, fact checking, proofreading) if you want to use that content for people, if you want to use it for backlinks on web 2.0s and other useless places like these the content produced by AF is ok. And that was when they used the GPT-2 model. Few weeks after I got banned from their software they've upgraded to GPT-3 so I assume that the content is better now, but... at the end of the day it's still machine generated content and you still have to fact check, proofread, and edit the content yourself.
- it inserts relevant images into the content (if the niche / topic of your keyword is broad enough for the software to be able to find relevant images), which makes the content pretty
- it's fast. You can generate one article in 2-3 minutes if I remember correctly (but with the fact checking and manual editing you will still end up spending 10-20 minutes on finalizing the article if you're a native english speaker, or over an hour if you're not a native english speaker... probably...)
Overall, AF is great for creating content for autoblogs that you don't care about, or for backlinks. The content is almost always 100% unique right out of the bat. Whether or not it makes sense or it's factually accurate, however... that's a different story
SEO Content Machine
I won't list what this tool does because I wouldn't be able to finish explaining until tomorrow. What I will say, however is that I've tried this tool twice, last year, and each time I had to stop using it because I'm too big of a lazy fucker and I can't be bothered to work for my money. Had I not been so lazy I would have used this software and probably gotten rich already.
And yes, this is a shameless promotion of SEO Content Machine (but no, I'm not affiliated in any way with it), I just freely recommend it because I feel sorry for the owner. I just feel like he's not getting enough customers for how much work he's put into this tool, and if you'll spend some time playing with the software you will be able to see the insane amount of work that's been put into it. It's also constantly updated and improved (based on the customers' feedback, too!), and for less than $150 per year that this tool costs you are getting a helluva service. I just can't recommend this enough, honestly. I think it comes with a free trial, so get it and see for yourself how complex and powerful the tool is. It handles all of the content creation and content optimization you might need for your money sites, autoblogs, PBNs, SEO tools, or whatever.
