AI translation rules

Tell AI how your spreadsheet should sound.

Add reusable instructions for terminology, tone, formatting expectations, and words that must remain unchanged.

← All features
Translation Rules Manager with reusable terminology and tone instructions
Custom Rules provides one reusable place for protected names, approved terminology, tone, and formatting instructions.

Why it matters

Consistent product names and preferred phrases matter more than a different creative rewrite in every row.

01

Protect brand terminology

Tell the AI engine which company, product, or feature names should stay in their original form.

02

Set tone and audience

Specify concise, formal, friendly, technical, or audience-specific wording.

03

Reuse your instructions

Advanced settings are remembered locally so repeat jobs do not start from an empty prompt.

How it works

Three steps in the sidebar.

  1. 01

    Choose an AI engine

    Select OpenAI, Claude, or Gemini in the Pro sidebar.

  2. 02

    Open advanced settings

    Add direct, testable translation instructions.

  3. 03

    Run a small sample

    Review a representative range before applying the rules to a full sheet.

Good practice

Custom rules apply to AI engines, not the free Google Translate engine. Always review output when terminology has legal, medical, or safety implications.
