A Brazilian voice, not a European one

The narration uses Brazilian Portuguese voices, Antônio and Francisca, so the accent and the word choice sound like Brazil rather than Portugal.

Built for school work

Students and teachers use it to turn history, geography and science topics into short explainer videos for class, like the video on the independence of Cape Verde in our gallery.

Your script, word for word

Paste a finished script in Portuguese and it is narrated exactly as written, split into boards at sentence breaks. Or type a topic and the script is written for you in Portuguese.
