rotranslator

A CLI translator to all supported roblox experience languages/locale. Very formal based on google translate.

What It Does

• translates to all 21 Roblox locale
• copies the final JSON to your clipboard by default (disabled in batch mode)
• stays open like an AI chat for easy and rappid translation

Why this?

• Roblox OpenCloud generative_ai translate_text endpoint doesnt support every experience language, see here
• DeepL doesnt support thai as an translation target

Examples

with --batch flag

2026-04-22.21-43-28.mov

Flags

• --help shows you the info of this flags list
• --meta Show detected input language, total time, and translated percent after the JSON.
• --no-copy Do not copy the final JSON to the clipboard.
• --compact Print compact JSON instead of pretty JSON.
• --batch Enter multiple inputs first, then translate them all in parallel.
• --concurrency 6 Set how many translation requests run at once.

Batch Mode

Batch mode is useful when you want to queue a few strings and translate them together.

Up to 15K characters per API call, batch takes use of this to partition requests. Start batch mode:

uv run rotranslator --batch

Flow:

• enter one line
• choose whether to add another
• when you stop, all queued inputs are translated in parallel
• each result prints as its own JSON object
• clipboard copy is off by default in batch mode

Output Notes

• terminal output is JSON only, unless you enable --meta
• clipboard gets only the JSON string
• if one locale fails, its value becomes null
• the app keeps running until you exit with Ctrl+C or Ctrl+D
