Trains on your own text archive and holds the brand voice across a whole campaign — not one good paragraph but two hundred consistent ones

About the company
Jasper was founded in 2021 by Dave Rogenmoser, John Philip Morgan and Chris Hull, first as Jarvis — a name dropped after Marvel objected. It was among the first to build a business on text generation and lived through a collapse: once ChatGPT was free, a thin wrapper around a model was worth nothing. It survived by turning into enterprise marketing — a brand voice trained on the company’s archive, whole campaigns, a promise to keep data out of training. There is no free tier, only a seven-day trial, and entry starts at fifty-nine dollars on annual billing.
