Substat Checker

How to use & how scoring works ▼ show

Getting started

Take a screenshot of your gear's substat panel in Star Savior, then either:

Ctrl+V (or Cmd+V) anywhere on this page to paste from clipboard
Click Paste from Clipboard
Drag and drop an image file onto the drop zone

OCR runs entirely in your browser — nothing is uploaded. Detected stats flash green in the manual entry grid. Always check the raw OCR output if something looks wrong and correct values manually.

Set the Item Level (default 15) before or after pasting. Every 3 levels adds 1 upgrade roll, so a max-level item has 5 upgrade rolls distributed across its 4 substats.

Overall percentile

The overall score runs 50,000 simulated items at your upgrade level with the same 4 stats and asks: how many scored worse? This captures both upgrade distribution luck and roll value luck.

Tiers

S TIER90th+ — top 10%. Keep.

A TIER75th–90th — strong piece.

B TIER50th–75th — above average.

C TIER25th–50th — replace eventually.

D TIERBelow 25th — replace priority.
