What it does

Tripeppi Echo Builder helps you design and track echo sets for your characters: choose main and sub stats, split builds across echo sets, compare presets, and see build ratings and roll probabilities — all stored in a spreadsheet that belongs to you.

Build editor

Set echoes, main/sub stats and set splits per character, with presets and coherence checks.

Probabilities & ratings

Background calculations estimate roll odds and rate your builds.

Optimizers

Tuner and cost optimizers help you reach your build goals.

Your data, your Drive

Everything lives in a Google Sheet copied to your own Google Drive.

How it works

You sign in with your Google account.
On first use, a personal copy of the build spreadsheet is created in your own Google Drive.
The app reads and writes that spreadsheet to display and update your builds, and runs background calculations through Google Apps Script.

Permissions & privacy

The app only requests the Google permissions it needs to work: managing your build spreadsheet, scheduling background calculations, and reading your email address to identify you. We do not sell or share your data. See the Privacy Policy for full details.
