👋 Hi Product Hunt, I'm Yein, Co-founder of LilysAI.
LilysAI started from a deeply personal frustration. I’m obsessed with learning from the internet’s goldmines—Y Combinator talks, the Lenny Podcast, Starter Story—but always felt like I didn’t have enough time to go deep. Every "summary tool" I tried felt too shallow, too generic. I still had to go back to the original content just to truly understand it. So I built what I needed myself.
We first launched in South Korea and in just one year, we reached 600K users and $1.5M ARR—growing fast thanks to a real need. Now, we’re stepping beyond South Korea and sharing LilysAI with the world. Like BTS, Blackpink, and Squid Game... maybe Product Hunt is our global debut stage 😄
Who’s it for? :
Anyone buried in endless content: marketers, engineers, doctors, creators, students, teachers—and especially, fellow information addicts.
What makes LilysAI special? :
While we support all kinds of inputs (videos, PDFs, articles), we pride ourselves on offering the best experience for video content. Our sleek viewer lets you fact-check every AI-generated report instantly.
You can chew on the important stuff—savor it, break it down, and fully digest it at your own pace—with handy tools like 'Term Explanation', 'Dive deeper' buttons, and auto-suggested report topics to guide you along the way.
Fun fact: we named it LilysAI because it echoes the word “Release”—we’re obsessed with rapid iteration. If you leave feedback, we’ll probably ship your request quickly. 🚀
Super excited to build the future of knowledge with all of you.
— Yein & The LilysAI Team ❤️
@yeinkim LilysAI를 사용하면서 뜻도 모르고 사용했네요. 무료로 며칠 사용하다가 마음에 들어서 연간 구독을 했는데 사용하면 할 수록 마음에 드네요. 다 좋지만 '대화노트'랑 '자료를 기반으로, 이미지가 풍성한 SEO최적화된 블로그 글을 작성해줘'가 제일 마음에 드네요. 지금까지 여러 유튜브 요약 ai를 사용해 봤지만 LilysAI가 최고네요. ai를 연간 구독한 것은 LilysAI가 처음입니다. 앞으로 더 잘 될 거라고 생각합니다. 감사합니다.
@yeinkim 릴리스 ai 너무 좋습니다 신세계를 접한 기분이었습니다 바쁜 일상속에서 빠르게 요약하고 공부 할수 있어서 참 좋습니다 지인들에게 많이 알리고 있습니다 ^^ 더 성장하길 기원합니다

@yeinkim LilysAI is a handy cursor for information addicts – brilliant summarization. Gave my support. Congrats on launch – I'm launching my product today too, feel free to check it out.
@yeinkim LilysAI를 사용해보면서 정말 만족하고 있어요. 여러 가지 AI 툴을 사용해봤지만, 이렇게 실용적이고, 콘텐츠 제작자 입장에서 꼭 필요한 기능들이 잘 정리된 서비스는 처음입니다. 특히 ‘대화 노트’ 기능이 너무 유용하고, 자료를 기반으로 이미지 없이도 SEO 최적화된 블로그 글을 뚝딱 만들어주는 기능은 정말 감동 그자체...
저는 LilysAI가 앞으로 더 성장할 거라고 확신해요. 진심으로 추천드립니다. 감사합니다 😊
@yeinkim Lylis ai 유투브를 통해 알게되엇는데 지금은 너무 잘사용하고 있습니다. 챗지피티도 못하는 유튜브 요약이라니!! 정말 삶의 질 향상시키는 똑똑한 도구, 없어서는 안될 도구입니다. 제 지인에게도 알려줬더니 넘 좋다고 하네요! 한국인니 만들엇다하시니 왠지 더 뿌득하고요 더욱더 발전되길 기원합니다

Hi everyone — I’m John, CEO of Lilys AI.
Like many of you, I was constantly overwhelmed by content I wanted to understand — videos, podcasts, PDFs, research papers — but rarely had the time or energy to fully go through. After starting my company, this only got worse. I needed to learn fast, and learn deeply.
I tried countless AI tools — but not a single one helped me truly understand even one piece of content. Most gave me summaries that were either too short, untrustworthy, or impossible to dig deeper into.
So we built Lilys AI — the tool I wish I had.
Lilys AI is built to help you fully absorb any content, not just skim it. Here’s what it can do:
View layered summaries — from short versions to detailed ones, including mind maps and full transcripts. You can even create your own summary notes, richly formatted with images and charts.
Click the + button to keep exploring — you can go as deep as you want, one layer at a time.
A powerful viewer connects each sentence to the original source with references and timestamps.
Supports YouTube, PDFs, web pages, DOCX, PPTX, and Excel files.
Confused by a word or phrase? Just highlight it and hit “Easy Explain” to get a plain-language breakdown instantly.
If you've ever felt guilty about not finishing a podcast or overwhelmed by a research paper, Lilys AI was made for you.
Would love your feedback or questions — happy to chat in the comments 🙌
@john_oh_11xy 안녕하세요 저는 직장 생활하며 자기 개발에 관심을 갖고 있습니다.
온라인을 통한 정보 수집과 손 글씨 쓰는 것을 즐기며 최근엔 독서와 영상을 통해 삶이 보다 나은 방향으로 나아가도록 노력하고 있습니다. 정보 수집을 하는데 있어 세상에 책과 영상은 너무 많아 내게 현재 필요한 지식을 신속하게 선별하는 능력이 중요해진 요즘입니다.
직접 읽어보고 싶은 책(혹은 더욱 깊게 알아가고 싶은 영상 정보)과 간단한 핵심 내용만 파악하고 싶은 책(혹은 영상)을 구분하기 위해 이동 시간이나 운동하는 시간에 오디오 형태로 책 혹은 정보의 핵심 내용을 정리한 영상으로 읽어 보고 싶은 책과 더욱 깊게 알아보고 싶은 영상을 선별하고 있습니다. 선별한 책이나 영상 중 마음에 드는 영상이나 글을 손으로 써보고 그 아이디어를 체화하는데 있어 마인드 맵이 생각과 기억을 뻗어 나가는데 좋은 역할을 합니다.
이동 시간이나 운동하는 시간에 오디오 청취하면서 발생하는 반복되는 문제점은 간혹 소리에 집중하지 못하는 상황에서 중요한 메시지를 놓치는 점입니다. 시간을 좀 더 효율적으로 정보를 정리하여 내 것으로 만들기 위해선 시각화가 필요했습니다.
제게 정보의 신속한 선별과 정확한 수집, 기록과 기억, 생각의 정리 및 확장을 위한 시각화 도구로 마인드 맵 모두 중요한 요소였고, 이를 대신해줄 무언가에 대한 갈증이 있었습니다. 그 무언가는 보통 영어로 표기되거나 번역을 한다해도 사용법을 직관적으로 파악하기 어려움이 있어 사용 빈도가 낮았습니다.
Lilys AI를 경험하고 위에 늘어놓은 내게 필요한 것을 가진 채로 불편했던 것들을 편리하게 만들어준 Lilys AI 창립자 및 엔지니어 분들에게 감사 인사를 남기고 싶어 댓글 남깁니다.

LilysAI 언제나 응원합니다!! 👍👍👍👏👏

👋 Hi Product Hunt! I’m Jinyoung, Product Engineer at LilysAI.
If you’ve ever stared at a 60-minute YouTube lecture, a dense research PDF, or a pile of Excel data thinking, “There’s gold in here—but I don’t have the time or energy to mine it,” you’re not alone. I’ve been there too.
That’s exactly why we built LilysAI—a tool that doesn’t just summarize, but actually helps you understand complex content, deeply and reliably.
What is LilysAI?
LilysAI is your AI-powered reading and watching companion. It takes YouTube videos, PDFs, Word docs, Excel files—even audio—and turns them into digestible, source-linked summaries you can trust and explore at your own pace.
📌 Why people love it:
Detailed summaries that don’t just skim—they explain.
Multi-source support: Upload multiple files or links and get a unified summary.
Source traceability: Every sentence in the summary links back to its original timestamp or page.
Smart tools for deeper learning: “Easy Explain”, “Dive Deeper”, term glossaries, and more.
Summary templates: A variety of formats like timeline, key, mind map, and insight talk notes to help you absorb content your way.
Whether you’re a researcher, creator, student, or just someone who hoards tabs for later—you’ll find LilysAI surprisingly powerful.
We’re on a mission to be the go-to product for anyone who wants to learn faster, understand better, and never feel lost in information again.
Would love to hear your thoughts and ideas. We're just getting started 🚀

As an early adopter from South Korea, where LilysAI first took off, I can confidently say this tool is a game-changer! Having extensively used both LilysAI and Google's NotebookLM, the difference is super huge.
What truly sets LilysAI apart is its speed and the sheer versatility of its summarization styles. Whether I need a quick overview or a detailed analysis, LilysAI delivers flawlessly. The integrated chat function is also incredibly helpful for instant clarification.
But the most significant advantage, especially with video content, is LilysAI's precision. Unlike NotebookLM, which often shows the entire transcript, LilysAI intelligently pinpoints key moments. This saves me so much time and lets me focus on what matters.
LilysAI
@solaqua Thank you so much for the detailed review! As you said, we think we have an advantage in terms of detailed organization, readable viewer, and more templates! We will continue to work hard to improve our product!
LilysAI
@solaqua Thank you so much for the kind words and for capturing LilysAI’s essence so perfectly!
I couldn’t agree more about the trust gap in other summarization tools—NotebookLM included.
That’s exactly why we built interactive citations and multi-layer summaries: so you can see and verify every insight instead of guessing what’s reliable.
Knowing LilysAI is saving you time and letting you focus on bigger things is everything we hoped for. We’ll keep pushing to make understanding even faster and more effortless, and we’d love to have you along for the journey!

It is very hard to understand foreign materials especially when you are out of time.
I personally watch foreign language materials a lot and felt like It is 10x faster with Lilys AI.

Absolutely love the concept behind LilysAI! In a world overflowing with content, having a tool that distills key insights from videos, PDFs, and articles is a real game changer.

Congrats on your global debut — rooting for your team as you scale beyond South Korea!

minimalist phone: creating folders
I am looking for more languages to be supported.
+ I tried it for YouTube summary and found it very useful. Finally, something where I can leave the link, and it will create a solid abstract.
Surprised that it offers the form, I can consume the overview (e.g. graphs, script and so on).
Hat off! 🙂🏆
