Translate sends your input to CastReader’s translation service. This tool does not save your original or translated text. Clear or leave the page to end the session. Reading uses on-device voices; languages depend on your device and browser, and do not use CastReader AI reading minutes.
Keep the original close
The original stays beside your translation. Check names, numbers and conditions before relying on the result. Translation changes the language; it does not explain or verify the content.
Listen one side at a time
Read the original to hear its rhythm, then read the translation to connect sound and meaning. Switch languages or edit the text to stop the previous reading.
Try the reverse direction
Swap after translating to move the result into the input. A reverse translation can reveal differences in wording, but is not proof that the first translation is accurate.
Before you begin
Is the translation read aloud automatically?
No. Translation and reading are separate actions. Press Read original or Read translation when you want to listen.
Why is a read-aloud button unavailable?
This tool uses on-device voices. A matching voice must be installed and exposed by your browser. You can still translate and copy the text when no matching voice is available.
Can I upload a PDF here?
This tool accepts pasted text. For a short PDF passage, copy its readable text here. It does not translate a PDF layout or transcribe scanned pages.
