Frequently Asked Questions

Can I translate very large .po files?
Yes. SimplePoTranslate supports large .po files and processes them automatically in batches.
What does "250,000 strings per month" mean?
A string is a single translatable entry in a .po file. Most UI strings are short labels or messages.
How does the fair usage policy work?
SimplePoTranslate counts usage based on strings, but internally applies weighted counting for very long texts. Each string counts as 1 usage unit by default. If a string exceeds the limit, it may consume multiple usage units to ensure fair usage and cover AI processing costs. Short UI strings typically count as a single unit.
How are long texts counted?
SimplePoTranslate is optimized for UI and application strings. Each string counts as one usage unit by default. If a string exceeds the limit, it may consume multiple usage units to ensure fair usage and cover AI processing costs.
Are my files used to train AI models?
No. Uploaded files are never used for AI training.
