Built for the Translators Rebuilding the Ship of Theseus.
“Even if every material that makes up a ship is replaced, its original course and the way it cuts through the waves endure.”
— The Ship of Theseus
Even when every word and grammar rule is replaced, the text's original context and intent must remain fully intact. Translation is the art of faithfully rebuilding original meaning with new materials.
We build the lightest, most independent, and powerful tool to preserve the true essence of translation.

Frequently Asked Questions (FAQ)
How does local-first architecture work and what are its security benefits?
Prism Studio stores all source documents and translated text in a secure local sandbox on your local machine. Your translation memory (TM) and original documents are never permanently uploaded to our servers. Even when you are offline, all features except machine translation and chatbot features (such as document editing, shortcuts, and local storage) work seamlessly, preventing any data leak risks.
How many languages does Prism Studio support?
Prism Studio is designed in compliance with the international ISO 639-1 language code standard, supporting translation for over 100 languages worldwide, including English, Korean, Japanese, and Chinese. It integrates world-class translation engines such as OpenAI, Anthropic, Google, and DeepL, allowing you to choose the best engine suited for your specific language pairs.
What file formats can be translated in Prism Studio?
We natively parse and support Word (.docx), Excel (.xlsx), and industry-standard localization formats (.xlf, .xliff, .sdlxliff), as well as Markdown (.md, .mdx), HTML (.html), JSON (.json), and plaintext (.txt) documents. Using our local parser, formatting tags and Markdown styles are fully protected while extracting segments, ensuring that your file structure and design are restored perfectly when you export the translated file.
Can I transfer my existing translation memory (TM) or translation database to Prism Studio?
Yes, you can easily import industry-standard translation memory files such as TMX and XLIFF into Prism Studio. Since all imported data stays on your local machine and is saved locally without being sent to external servers, you can leverage your existing translation assets securely.
What are the advantages of Prism Studio compared to other translation and localization solutions?
Prism Studio focuses strictly on security and productivity. First, with our 'local-first' architecture, all source documents and translation assets remain on your device (local sandbox), ensuring zero risk of data leaks. Second, our shortcut-driven UI enables editing, segment confirmation, and file switching via shortcuts and the shortcut commands without reaching for a mouse. Third, our context-aware translation passes surrounding text to the AI to resolve ambiguous pronouns and keep a consistent tone.
