it's a bad deal, though, cause the content is not that good and you have to burn through a lot of words to create good content. Other tools have much better deals. Maybe they're not as "advanced" as Jarvis, but they surely beat its price. Just purchased Rytr 1 week ago and you get unlimited words for $29/month, not just 20k.
Writesonic is good, too, and you pay like $10 a month for 150 credits or something like that. I don't know how many articles you can create with those credits, but it's still better than Jarvis (conversion.ai).
This being said, you can use Jarvis with group buy tools for like $5 a month... to create 5k words a day. Still better than their $29 / month offer
