Drowning in information, you're likely missing valuable insights. LilysAI instantly extracts key takeaways from YouTube, PDFs, and articles—letting you dive deeper with one-click tools like mind maps and more. Reading alone just isn't enough anymore.
I've been using it since the very beginning of the product launch, and I'm really impressed with how well they find what users need and improve it and upgrade the product very quickly.
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. The sleek interface and features like mind maps and "Dive deeper" buttons sound incredibly helpful for both productivity and deep learning. Congrats on your global debut — rooting for your team as you scale beyond South Korea!
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).
Hey team, LilysAI is seriously impressive—feels like the ultimate tool for curious minds! You should consider listing it on Aixyz .Co—it’s a free directory for tools like yours, and a great way to reach more AI and productivity fans. Keep up the awesome work!
Hello! I’m Jihye Kang, a Product Engineer at Lilys AI.
I’m thrilled to be launching our proudest creation for the very first time on Product Hunt.
Driven by our mission—“Helping everyone digest knowledge quickly and deeply”—we’ve poured our hearts into understanding real user needs and crafting the perfect product.
By combining diverse materials, forging connections, enabling rich interactions, and guiding exploration,
Lilys AI is evolving into the ultimate knowledge-digestion tool—so you never have to wonder how best to absorb information again.
Already, we’ve layered multiple interactive features and tools to transform from a simple summary AI into a comprehensive knowledge companion.
Those layers form our sharpest roadmap, propelling us beyond basic summarization toward a true understanding platform.
Since launch, countless releases and relentless user research—observing behavior, conducting interviews, pivoting quickly, and shipping improvements—have taught us that staying focused on user needs and our core mission is the only way to build something truly valuable.
Trust our team—constantly innovating without losing sight of both product excellence and user care—and try out the amazing Lilys AI for yourself.
You won’t be disappointed!
Hi guys! I’m Kiwoo, Product Engineer at LilysAI.
I’m thrilled to premiere on Product Hunt! I’ve always dreamed of launching here—it’s a privilege to be supported by hundreds, even thousands, of product enthusiasts.
What held me back with earlier projects was a lack of confidence and a fear of sharp feedback. Deep down, I sensed they weren’t ready to break through—and I was right.
But today I’m proud to introduce our team and our product, LilysAI. Not because I merely believe it will be ground-breaking, but because it already is.
LilysAI is all about fast, effective comprehension. True understanding isn’t a one-shot AI summary—it’s interactive. After interviewing countless students, researchers, and knowledge workers, we learned that real study is inherently interactive.
LilysAI surrounds every source with rich interaction layers. Read a summary, click any point to jump to the cited passage, chat with an AI agent, highlight, clip, edit—everything you need to comprehend.
We’re obsessed with weaving these layers into a seamless experience, and we’re confident you’ll find this the optimal way to master any material.
So dive in, explore LilysAI, and comprehend like never before.

👋 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 🚀

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 onehelped me truly understandeven 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 🙌
👋 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.
