P2P Estimating vs STACK
The verdict: P2P is the better fit if you want AI to do the takeoff; STACK is the better fit if you want a cloud platform for manual takeoff with broad team and document features.
P2P Estimating vs STACK
STACK is a cloud takeoff and estimating platform with strong collaboration and document management. Like most tools in the category, the takeoff itself is still manual — you measure on screen. P2P automates the takeoff with AI and prices it for you. Here is the comparison for a sub focused on bidding faster.

Mature team & document platform

Broad material/cost databases
STACK offers extensive catalogs and reporting some larger operations want built in.
STACK uses tiered subscriptions. P2P is free to try with no login, paid plans from $99/mo, ~$25–$75 of credit per estimate.
Choose P2P if your bottleneck is the takeoff itself and you want it automated. Choose STACK if you need a full team platform and are fine doing the measuring manually.
