Myna is a Mac app that runs end‑to‑end AI localization for product copy on your machine. Connect your own OpenAI API key, drop in XCStrings, App Store metadata, or XLIFF files, and translate into 36 languages at cost. Myna scores every string for accuracy, fluency, terminology, formatting, completeness, and cultural fit, automatically retries weak translations, and reuses local translation memory and glossaries so you can export ready‑to‑ship files in your existing formats.
