For Hearts of Iron IV

Your HOI4 division planner.

Build templates, plan research, compare doctrines, and discuss strategies with the community. All in one place.

Powerful tools

HOI4 division, tanks, & fleet planning. Live stats, no spreadsheets.

Every build, recalculated live, so you know what you’re committing before you unpause.

Designers

All units, modules and slot rules. Experiment in the browser with what's actually allowed and plan a few steps ahead.

Research & doctrines

Research and doctrines are layered on top of your templates and designs and feed straight into your stats as you plan your army. Walk the tech and doctrine routes you want to play toward and see how each step shifts your numbers.

Analytical tools

Compare any two builds side by side. Dynamic stat deltas and heatmaps make it easy to spot where one wins and what you're giving up.

All your builds, one workspace.

Every build you save lives in your Library. Organize them your way and pick them up whenever you need them on any device.

Share your work

Post your build.
Let the stats speak.

Rate my build? Every card packs battalion layout, combat stats, and terrain modifiers into one shareable image. Build something. Export it. Drop it anywhere to get feedback.
