I Let AI Translate My YouTube Titles. Then I Asked What It Actually Said.

Description and use

Channel Tongues automatically translates YouTube video titles and descriptions into 12 languages, validates them, and publishes via the YouTube Data API while keeping local backups.

Problem

YouTube automatically machine‑translates video titles and descriptions for foreign viewers, but creators never see or control those translations.

Outcome

The tool reduces manual effort, ensures translation quality through checks and read‑back, and keeps the channel’s credentials local.

Workflow

• Open YouTube Studio and the Channel Tongues Chrome side panel
• Press Translate to run Gemma 4 locally via Ollama
• Review the translated titles/descriptions and read‑back English translations
• Untick any translations that fail checks
• Press Publish to send the approved translations to YouTube through the API
• Backup current translations before publishing
• Restore from backup if needed via the panel or command line

Evidence

Channel Tongues opens next to YouTube Studio as a Chrome side panel; you press Translate, and Gemma 4 running on your computer through Ollama writes the title and description in the twelve languages with the biggest YouTube audiences.

The helper runs the model, keeps the sign‑in file and writes backups, and Chrome starts it when you open the panel.

The read‑back line. A placeholder check can’t tell me what a Thai title means. So the same model translates each translation back into English, and the panel shows it under the title.
