Offer me or build a text generator from Keywords

Hi everyone, I need to generate descriptions for 100k+ videos asap, i will have all the data in an Excel file ( Actor name, primary keywords, secondary keywords) and then your software will generate a natural text like if it was an human who written it. I want something seamless, no pre-built excel template with repetitive core. The description will need to be imported on the same excel file. Each description will have a length of 200 words. Have a look on this tool : [login to view URL] I want pretty much same features but I want something one time buy, no monthly membership or no pay per text cost.
