Jasper: Marketing copy in your brand voice: campaigns, posts and landing pages from templates.

Spellbook: Lawyer's assistant in Word: tracked-change edits, missing clauses and risks.

The brand knowledge base takes public product facts only: unreleased products and prices under NDA stay out
Copy in languages other than English comes out with literal calques: have an editor or LanguageTool proofread it before publishing
The model readily writes benefits the product does not have: check every claim about features against the facts

Spellbook takes market standards from common law practice: edit clauses on jurisdiction, penalties and currency for your governing law yourself
Review every tracked change before accepting: a bulk "accept all" brings the other side's positions into the contract
Contracts with real parties are processed in the cloud: check the vendor's confidentiality terms before the first client contract
