But most are really just wrappers connected to OpenAI's GPT-3 and GPT-4 APIs, with a few extra features built on top-even if they try to hide it in their own marketing materials. Some of the bigger apps are also integrating their own fine-tuning or using other LLMs like Claude. There's a big reason for this: 95% of these AI writing tools use the same large language models (LLMs) as the back end. Search Google for AI writing software, and you'll find dozens of different options, all with suspiciously similar features. So, if you're looking for an AI content generator that will help you write compelling copy, publish blog posts a lot quicker, and otherwise take some of the slow-paced typing out of writing, you've come to the right place. These AI writing tools are getting incredibly impressive, but you have to work with them, rather than just letting them spit out whatever they want. Since AI is supposedly trying to take my job, I'm somewhat professionally interested in the whole situation. I've been covering this kind of generative AI technology for almost a decade.
