Lets be honest: Jasper/Jarvis/Conversion.ai were one of the first and probably the best on the market for 1-2 years. But now they are redudant, because people can directly use ChatGPT for free or for $20 per month.
The majority of people who are still subscribed to Jasper are fans of the brands. Some dorks who feel obligated to support the company/brand, while they are completely overpricing their service.
GPT 3.5 became much cheaper than the previous GPT 3. Since Jasper was running on GPT 3 and then got upgraded to GPT 3.5 it made them save tons of money for using the OpenAI API.
Also the Jasper company is a very good example of how you can shoot yourself in knee. They made a company based on GPT 3 / OpenAI, hired a lot of staff, etc. and now their USP became mainstream, everyone knows how to make the same website/SaaS, even OpenAI themselves have ChatGPT. They should have see this coming, earn as much money as possible....but hiring a lot of people and then keep offering the same product....not really smart a good move imo
