Free Polish subtitle generator

Drop a Polish-language video and Captionly transcribes it with AI Whisper, lets you fix names and proper nouns with a click, and exports SRT, VTT, ASS or a burned-in MP4. Detects Polish automatically. Free, in-browser, no signup.

Polish-language video has its own audience and its own search index. Captions extend the reach: they make Polish video accessible to sound-off viewers, indexable to search in Polish, and ready for downstream translation. Captionly is a free Polish subtitle generator that runs Whisper locally in your browser, supports inline editing, and exports the formats every editor and platform accepts.

Whisper transcription for Polish

OpenAI Whisper transcribes Polish into its native script with word-level timing. Runs entirely in your browser via WebAssembly — no upload, no API key.

Click-to-fix Polish transcript

Misheard a name or proper noun? Click the word, type the correction in Polish, the timing stays locked. Glossary handles recurring slips across the whole video.

Native Polish characters preserved

All exports are UTF-8 so Polish characters, diacritics and punctuation survive cleanly into SRT, VTT, ASS and the burned-in MP4.
