who_its_for

Multilingual publishers and educators

Useful when one source set needs to become multiple language versions without paying for another SaaS translation layer.

Researchers and content operators

A fit for folders of PDFs, DOCX files, Markdown notes, and text files that need repeatable translation rather than one document at a time.

People who want cost control

Strong if you want to choose your own provider, translate into multiple target languages, and keep the outputs on your own PC.

privacy_and_control

This is a bring-your-own-key translation workflow. You choose the provider, model, and cost profile. API keys are encrypted locally using Windows DPAPI. The translated outputs are saved to your PC, not stored in a hidden 3thousand30 service.

Important distinction: local files stay local after translation, but the translation request is sent to the external AI provider you selected. That transparency is part of the product promise.
