What Can the Chaldeas Planner Help Fate/Grand Order Masters Plan?

Updated

Chaldeas is the planner half of Chaldea, a cross-platform tool for Fate/Grand Order. According to the site's own description, it helps masters plan materials, servants, events and so on — so if your question is "what can I actually track in it?", the short answer is: the long-term resource and roster decisions that are painful to hold in your head. It is a planning tool, not a gameplay automation tool, and the site does not state pricing or account requirements, so treat access details as something to confirm on the site itself.

The three planning areas the site names

The Chaldea homepage describes Chaldeas as "a planner to help masters planning materials, servants, events and so on." That gives three concrete buckets:

Planning area What it covers in practice
Materials The ascension, skill, and enhancement resources you need to gather
Servants Your roster and the servants you are building or targeting
Events Event-related planning, so limited-time content does not collide with your farming goals

The "and so on" matters: the description is deliberately open-ended, so the planner is positioned as a general-purpose planning surface rather than a single-purpose calculator.

Why this pairs with Laplace

Chaldea is composed of two parts. Chaldeas is the planner; Laplace is described as "a novel battle simulator to help building your team, help 3T farming." The split is useful to understand before you invest time in either:

  • Chaldeas answers "what do I need, and by when?" — materials, servants, events.
  • Laplace answers "does this team actually work?" — team building and 3-turn farming simulation.

If your goal is deciding what to farm next, Chaldeas is the relevant half. If your goal is testing whether a farming composition clears in three turns, that is Laplace's job.

What to expect when you open it

The page evidence shows the app requires JavaScript to run, and the visible state is a loading screen ("Starting...") with a link to a document site. Practical implications:

  1. It runs in the browser as an app, not as a static page — so a JavaScript-enabled browser is a prerequisite.
  2. There is a separate document site, which is where you should look for setup steps, terminology, and feature-level detail rather than guessing from the app alone.
  3. Cross-platform is stated in the description, so the same tool is intended to be usable across devices rather than locked to one platform.

Choosing whether it fits your needs

Chaldeas is worth using if you:

  • Are planning a servant build and want the material requirements in one place.
  • Want to coordinate event participation with your broader farming plan.
  • Want planning and battle simulation in the same ecosystem, since Laplace sits alongside it.

It is probably not what you want if you are looking for a damage calculator only, or for something that plays the game for you — the description frames it strictly as planning and simulation.

Where to go next

Start at chaldea.center, let the app load, and use the linked document site for the specifics of each planning area. Because the homepage description is high-level, the document site is the reliable place to confirm exactly which materials, servants, and events are supported and how they are entered.
