How tools are selected
Every tool on aistacks is manually reviewed before being added. We look at real-world usage, workflow fit, and whether it genuinely saves time — not just popularity.
What belongs in a good stack
Tools are grouped by workflow role — not thrown together. Each stack is built around a specific persona and task, so every tool has a clear reason for being there.
