Show HN: I Built a Free AI LinkedIn Carousel Generator (opens in new tab)

LinkedIn Carousel posts have the highest engagement rate, but as an engineer, instead of spending hours on Canva, I wanted to build a tool that can generate LinkedIn carousels automatically.

built this for my own startup and would like to give it to the HN community for free.

Feel free to try it out—no email or signup required!

How it works:

[1] Provide a prompt. [2] Pick a theme (Professional, Creative, Tech, Minimalist, or Casual). [3] Adjust settings (colors, number of slides, etc.) and add branding.

Tech-Stack Built using Firebase Studio LLM: Gemini 2.5 Flash lite (all I can afford to keep it free, and I found it was capable enough for the task. If there's interest, maybe I can add a pro version with stronger LLMs, and perhaps generate background images using Nano Banana)
