Built for Brazilian Shorts, Reels and TikToks
Brazilian creators post short videos on everything from curiosities to history, science, football and personal finance. Many of those channels are faceless: a voice, captions and visuals that change with every sentence. ContentRoof makes exactly that kind of video from one line of text.
The AI drafts the script in English for accuracy, then translates it into natural Portuguese. A neural voice with a Brazilian accent reads it with word timing, so captions highlight each word as it's said and drawings arrive on cue.

Topics that work well in Portuguese
- Curiosidades: "Você sabia que...?" facts about the body, animals or space. The hand-made heart, brain and black hole animations suit these well.
- Brazilian history and geography: the Amazon, the bandeirantes, the founding of Brasília. Name São Paulo, Manaus or Salvador and the globe flies there.
- Football: records, titles and transfer sums that count up on screen.
- Personal finance and economy: inflation, interest rates or the price of things over time. The data story mode draws a line or grows bars as each number is said, using your numbers exactly.
- Quizzes: a question, options, a 3-2-1 countdown and the right answer lighting up green.
Tips for Portuguese narration
- Write for Brazil if your audience is in Brazil. The voice has a Brazilian accent, so Brazilian vocabulary and "você" read naturally. For audiences in Portugal or Africa, edit the wording, but the accent stays Brazilian.
- Length. As a starting point, aim for about 140 to 160 words for a 60-second Short, then check the length in the preview and adjust the voice speed if needed.
- Hook first. Start with the strangest fact, not with "Olá, pessoal".
- Numbers. Write them as plain digits (1500, or "3 milhões") rather than with thousand separators, so the on-screen counter reads them right. Portuguese uses a comma for decimals (3,5); listen to the preview to check how they're read.
- One idea per paragraph. Each paragraph becomes its own scene and picture.
Formats and posting
Vertical for Shorts, TikTok and Reels; 16:9 for regular YouTube, with the narration on the left and the animation on the right; square for feeds. The post kit writes Portuguese titles, a description, tags, hashtags and captions for TikTok and Instagram from the same script, and the carousel export turns every scene into a slide for Instagram or a PDF for LinkedIn.
