3Cross-Language Features
Cross-Language Summarization
Watch a Japanese lecture and get an English summary. Watch an English tutorial and get a Spanish summary. The AI handles comprehension and output simultaneously, producing natural-sounding summaries in your target language.
Auto-Translated Transcripts
YouTube auto-translates captions for many videos. In the Transcript Generator, look for the "AUTO" section in the language dropdown. Quality varies — auto-translated is generally less accurate than original language.
Right-to-Left Languages
Arabic, Hebrew, Persian, and Urdu are fully supported. Output displays correctly in RTL format when you copy/export. Both transcript and summary tools handle RTL languages properly.
4Tips for Best Multi-Language Results
Use Original Language When Possible
Original language captions are more accurate than auto-translated. If you understand the video's language, extract transcripts in original for highest accuracy, then use summarizer for output in your preferred language.
Technical Content
For technical videos, the AI preserves terminology appropriately. Some terms may remain in English (global technical standard) while context is explained in your target language.
Check Caption Quality
Videos with manual captions (uploaded by creators) produce better results than auto-generated. Look for the "CC" icon on YouTube player — manual captions often have a "CC" label vs auto-generated.
