For Writers — Promise Legal Insights
Insights for Writers
Substack operators, newsletter publishers, and indie authors running their own publishing business.
Newsletter operators, Substack publishers, and indie authors increasingly run real businesses with revenue, contracts, and AI-training-data exposure that didn't exist five years ago. Publishing contracts that read fine in 2018 are missing critical clauses today — audiobook subrights, AI training opt-outs, ghostwriting frameworks for AI-assisted work, and the platform terms that govern your distribution.
This hub is for writers running their work as a business — newsletters, indie publishing, ghostwriting, audiobook deals, and the contracts that connect them.
Content sprint: Active content sprint underway. New posts on Substack monetization tax, modern publishing contract clauses, AI training opt-outs for writers, and audiobook subright negotiation are in development.
