Gamma API- Auto-generate decks, docs and carousels from raw input
Hi HN, I’m Sarafina, an engineer at Gamma, and I’m here to share something we’ve been building the Gamma API, now in public beta. We originally built Gamma as a way to turn rough content into shareable decks and documents, a kind of design layer for non-designers. Over time, we got more automation requests to enable quickly creating new sales pitches, lesson plans, or meeting summaries. The Generate API takes in raw input like text, meeting notes, or CRM data and returns polished content. You can generate: Slide decks Docs Social carousels (LinkedIn-style) All fully designed, brandable, and…
In plain words
Gamma API is a public beta tool that converts raw input like text, meeting notes, or CRM data into polished, professionally designed presentations, documents, and social media carousels. The API accepts POST requests with content and configuration options, returning fully branded outputs exportable as PDF or PPTX. It supports over 60 languages, customizable themes, and AI-generated images, designed for developers and teams needing to quickly generate sales pitches, lesson plans, or meeting summaries without manual design work.

You can generate: Slide decks Docs Social carousels (LinkedIn-style) All fully designed, brandable, and exportable to PDF or PPTX. How it works: You pass a POST request with the input and config (tone, format, theme, etc.) The API responds with a Gamma link (hosted doc), or export file Works with 60+ languages, customizable themes, and AI image support We’d love feedback, especially from developers thinking about “visualization layer” workflows inside internal tools or automation stacks. AMA! -Sarafina (Gamma Engineering)

I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
