EIP Build Planner and BG3 Compendium are two web planners for Baldur's Gate 3 that, at first glance, do the same thing: choose race, class, multiclass, and stats. The difference is what happens after you build. EIP optimizes for speed; Compendium optimizes for legibility over time.
Speed vs organization
EIP is the more immediate entry. You move from race to stats to classes with no intermediate steps, and in ten minutes you have a level 12 build ready. If the build is single-class and you'll execute it once, that's all the flow you need.
Compendium leans into organization. Its uncluttered UI separates information into sections, adds inventory sets to plan gear by stage of the playthrough, and a notes panel to record why you made each decision. Making the most of that takes a bit more discipline, but in exchange the build ends up documented.
When documentation matters
The difference shows when a build gets elaborate: a three-way multiclass, gear swaps per act, item dependencies. Without a place to note the reasoning, you end up re-deriving your own plan every time you open it. That's where Compendium wins: the notes and sets let you return to a saved build and understand it immediately.
For a simple build you won't reread, that structure is overhead. EIP gives you the result without asking you to organize anything.
The party planner
EIP integrates a party planner to design all four characters together. Compendium focuses on the well-documented individual character, not the group. If your question is about the whole party, EIP answers better; if it's about a build you want to perfect and keep, Compendium.
When each one wins
| Case | Better option |
|---|---|
| Building a quick, single-class build | EIP Build Planner |
| Documenting a complex build to reread | BG3 Compendium |
| Separating gear by stage of the playthrough | BG3 Compendium |
| Planning all four party members | EIP Build Planner |
| Keeping a repository of understandable builds | BG3 Compendium |
Recommendation
If you want speed and party planning, EIP. If you want a documented build that still makes sense weeks later, Compendium. Many players use EIP for a quick first build and save Compendium for the projects they really want to keep. Each tool has its full analysis in the codex.
