One script, a whole continent of viewers
Spanish-language Shorts, TikToks and Reels reach viewers from Mexico to Argentina to Spain. The challenge for a creator isn't the audience; it's producing a polished video every day. ContentRoof turns a single line into a finished Spanish video: script, voice, captions, visuals and music.
The AI drafts the script in English first, for accuracy, then translates it into natural Spanish. A natural Spanish neural voice reads it with word timing, so captions highlight each word as it's spoken and drawings appear as their words are said.

Topics that suit Spanish-speaking audiences
- Pre-Columbian history: the Maya, the Aztecs, the Inca. Name Cusco or Lima and the globe flies there; dates appear on a timeline.
- Exploration and empire: write "de Madrid a Lima" and the globe frames both cities, dropping a pin on each as the narration names it.
- Geography and records: the Andes, the Amazon, the Atacama desert, with counters for heights, lengths and distances.
- Football in numbers: goals, transfer fees, attendances that count up on screen.
- Science and space: black holes, DNA, the brain and galaxies have hand-made animations.
Tips for Spanish narration
- Choose your register and stick to it. Tú or usted, vosotros or ustedes. The AI writes neutral Spanish; edit it towards your audience's variety if you want a local feel.
- Spanish runs long. Spanish usually needs more syllables than English for the same idea. As a starting point, aim for about 140 to 160 words for a 60-second Short, then check the length in the preview.
- Keep the opening question short. "¿Sabías que...?" works, but the surprise should arrive within the first sentence.
- Use plain digits for big numbers. Spanish writes thousands with a point or a space depending on the country, and both can trip up an on-screen counter. Writing 1500 or "3 millones" is safest; listen to how it's read in the preview.
- Maps work best with names spelled as in English. Lima, Madrid, Cusco and Buenos Aires are recognised; Spanish-only spellings such as Sevilla or México may get a drawing instead of a map.
- One idea per paragraph. Each paragraph becomes a scene with its own picture.
Formats
Vertical for YouTube Shorts, TikTok and Instagram Reels; 16:9 for a regular YouTube video, with the narration on the left and the animation on the right; square for Facebook and LinkedIn. You can also export a thumbnail and a carousel (PDF for LinkedIn, images for Instagram). The post kit writes titles, a description, tags and hashtags from your script.
