The Founder's AI Stack: 20 Tools for Writing, Customer Replies, Bookkeeping and Content Creation
AI now lets a three-person team do the work of a team of ten. The hard part is no longer access, it is choosing. So here are the five best AI tools in each of the four categories every business touches every week: writing, customer replies, bookkeeping and content creation, with a simple starting stack at the end.
A note before the list: AI tools change fast, and features and pricing move month to month. Treat this as a shortlist to try, not a final verdict, and confirm current capabilities and plans on each tool's own site before you commit.
