Carosello

Hey PH! I built Carosello because I was spending 1-2 hours per LinkedIn carousel in Canva — choosing fonts, aligning boxes, exporting slides one by one. Carosello does the entire thing in about 5 minutes: 1. You describe your topic (or upload a document) 2. AI writes the post — hook, key points, CTA, hashtags 3. AI generates a unique image for every slide using Gemini 4. You tweak anything in the editor, then export as a ZIP What makes it different: - Image to Prompt — Upload any image and extract a reusable text prompt from it - Retouch Mode — Click on a specific area of a generated image to fix just that part - 16-color brand system — Set your brand colors once and every image stays on-brand - BYOK (Bring Your Own Key) — Use your Google Gemini API key and the tool is completely free. You pay Google directly, roughly €0.10 per carousel - No subscriptions — Buy credits when you need them, they never expire The BYOK model was important to me. I didn't want to lock anyone into a monthly fee for a tool they might use 4 times a month. With your own API key, Carosello costs you nothing. Would love your feedback — especially on the image generation quality and the editing workflow.
