The Carousel is the center feature of Notas BLA. You write a note with some sections marked by two hashes (H2 in markdown vocabulary), tap the Carousel button on the editor top bar, and in two seconds each section becomes a card ready for Instagram. In three sizes: Standard at 1124 by 1500 pixels (for the regular feed), Square at 1080 by 1080 (for the profile), Stories at 1080 by 1920 (for Stories and Reels).
The logic is direct. The app reads your note, finds all blocks delimited by H2, and renders each block as a carousel page. The H2 title becomes the card title, in large serif New York. The text below the H2 becomes the body, in editorial typography comfortable for reading on Instagram. If there are lists, quotes or bold, the app preserves the visual formatting.
The applied typography is BLA’s typographic palette: serif Literata for the main text, monospace IBM Plex Mono for the editorial eyebrow at the top of each card. Colors in Areia BLA paper #F1EEE7 as background, Tinta #2A2723 as text. Result: cards that look like magazine pages, not PowerPoint slides.
The rendering is via SwiftUI Canvas, not HTML turned into screenshot. Each element is drawn natively at high resolution. The result is a PNG with print quality, exportable straight to iPhone Photos (or macOS Photos, on the Mac). You tap Save, the PNGs go to Photos. You open Instagram, choose the photos, post the carousel. The whole flow, from writing to publishing, takes less than five minutes.
The decision to use H2 as separator was editorial. H2 is section, H3 is subsection, paragraph is continuation. A carousel is a sequence of sections, not a sequence of paragraphs. Whoever writes a note with H2 is thinking in structure. Whoever writes without H2 is thinking in flow. The Carousel respects the difference.
A comparison with doing it manually: to create a five-card carousel in Photoshop or Figma, you open the program, configure the canvas size, choose font, define alignment, copy and paste the text, adjust spacing, save. Each card takes about ten minutes. Five cards takes almost an hour. In Notas BLA, it takes two seconds. Five cards in two seconds is one hundred and eighty times faster. The math justifies the app.
For whoever maintains consistent Instagram presence (content creator, small company, editorial house, professional with own profile), the automatic Carousel changes the math. You do not need a designer for every post. You do not need Photoshop. You need to write well and tap a button.
The signature feature of the app is this. Without the Carousel, Notas BLA would be just another beautiful markdown editor on the App Store. With the Carousel, it is the tool that turns text into a publishable piece. It is the main reason to buy the app.
