Quick definition · 2 min Builder & startup term
SaaS
SaaS (software as a service) is software you pay for by subscription and use in your browser, instead of buying and installing it.
Think of it like
Renting vs owning. You pay monthly for access, always up to date, instead of buying a boxed copy.
Example
Netflix, Notion, and most AI tools are SaaS: a monthly fee for ongoing access.
Why it matters
SaaS is the default business model for software, including most AI products. The acronym is everywhere.
