Gamma API- Auto-generate decks, docs and carousels from raw input

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.

Build with the Gamma API — generate presentations, documents, websites, and social posts programmatically.

In the maker’s words, at launch

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…

  Hi HN, I’m the maker of ChartGen AI. Last year, we launched a text-based AI agent called Ada.im. After analyzing thousands of user interactions, we stumbled upon a pattern we hadn't expected: users were constantly trying to paste data rows and ask for visual representations, but the text-based model couldn't handle it well. We realized that for marketers, seeing the trend is more valuable than reading about it. We pivoted that insight into a standalone tool: Drag & Drop: Upload raw CSVs (FB Ads, GA4, TikTok, etc.). Processing: We map the disparate column names into a unified schema. Viz: It…

  Talanoa▲338

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Term.everything – Run any GUI app in the terminal▲1,094

  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…

  I recreated Windows XP as my portfolio▲1,032

  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…
