Reduce cost & time. Increase accuracy.

Our translation engine intelligently splits files, reuses cached translations, and processes chunks in parallel — so you pay less, wait less, and get better results.

Smart Splitting

Large files are split at logical token boundaries into optimally-sized chunks, ensuring the LLM receives well-structured code instead of arbitrary cuts.

Cache Reuse

Chunks where all strings are already translated are skipped entirely — no API calls, no token usage, no extra cost.

Parallel Translation

Remaining chunks are sent to the LLM simultaneously, so total translation time equals the slowest single chunk — not the sum of all.

Easily edit existing translations

You can easily edit existing translations, or generate new translations using AI.
