AI SaaS
AI SaaS is multi-tenant software whose core paid job is performed by a model API, with accounts, plans, and a usage cap.
In depth
The product is the workflow (extract invoices, write ads, qualify leads), not access to a generic chat. Without metering, one user can erase your margin.
Default stack: Next.js, Postgres, Stripe, one model vendor. See AI SaaS MVP and how to build SaaS with AI.
Real example
A tool that turns discovery-call transcripts into CRM notes, billed per seat plus credits.
