MetalGlot is a desktop application designed for local AI translation, specifically tailored for software developers and content creators who need to translate text and structured files without using the cloud.

Key Features

Privacy & Data Sovereignty: All translation happens 100% locally on your own hardware. It is "air-gap ready" with no telemetry or external API calls, ensuring your intellectual property remains private.
Localization-First Workflow: It is built to handle i18n files, such as XLIFF, ARB, JSON, PO, YAML, and Fluent, while preserving placeholders and file structures.
Predictable Cost: Unlike many SaaS models, MetalGlot uses a one-time license for unlimited usage, eliminating per-token fees and subscriptions.
Flexible Hardware Scaling:
- CPU: Can run smaller models like TranslateGemma 4B (requiring 8GB+ RAM) on standard laptops.
- GPU: Can scale to TranslateGemma 12B or 27B on workstations with NVIDIA graphics cards (16GB–32GB+ VRAM) for higher efficiency and technical complexity.

How it Works

The app uses a Docker-based architecture to run AI models locally. Users install the desktop app, which helps set up the Docker environment, download the preferred TranslateGemma models, and then manage translation tasks through a reviewable workflow.

Language & Format Support

It supports over 300 languages and 13 file formats, including plain text, markdown, and subtitle formats like .srt and .vtt.
