A secret weapon for anyone who needs content. I don’t need to tell you how important it is to optimize every step in your SEO pipeline. But unfortunately, it’s nearly impossible to cut out time or money when it comes to getting good content. At least that’s what I thought until I came across Article Forge… Built by a team of AI researchers from MIT, Carnegie Mellon, Harvard, Article Forge is an artificial intelligence (AI) powered content writer that uses deep learning models to write entire articles about any topic in less than 60 seconds. Their team trained AI models on millions of articles to teach Article Forge how to draw connections between topics so that each article it writes is relevant, interesting and useful. All their hard work means you just enter a few keywords and Article Forge will write a complete article from scratch making sure every thought flows naturally into the next, resulting in readable, high quality, and unique content. Put simply, this is a secret weapon for anyone who needs content. I get how impossible that sounds so you need to see how Article Forge writes a completearticle in less than 60 seconds!
Hey there! Quick question that’s completely off
topic. Do you know how to make your site mobile friendly?
My site looks weird when browsing from my iphone4.
I’m trying to find a template or plugin that might be able to correct this problem.
If you have any recommendations, please share.
Cheers!

Your place is valueble for me. Thanks!…
Are you writing the articles in your website yourself or you outsource them?
I am a blogger and having difficulty with content. Other bloggers told me I should use an AI content writer, they
are actually pretty good. Here is a sample article some bloggers shared with
me. Please let me know what your opinion on it and should I go ahead and use AI
