Lilys AI

Lilys AI is a multimodal AI-powered summarization and research workspace designed to combat “information obesity” by transforming long videos, audio, documents, and web content into structured, source-grounded insights with sentence-level citations and timestamps.

Evolving beyond its origins as a YouTube summarizer, it now supports diverse inputs (videos, audio files, PDFs, websites, raw text), generates visual outputs like mind maps, infographics, timelines, and quizzes, and emphasizes transparency through its DeepSearch feature that links every claim back to exact source locations.

With strong multi-language capabilities, agentic workflows, and integrations such as Notion exports, Lilys AI positions itself as a productivity and research hub for students, creators, professionals, and lifelong learners, distinguishing itself through speed, visual thinking tools, and verifiable summaries.

Lilys AI Review 2026: Multimodal YouTube & PDF Summarizer with DeepSearch Citations

The world of digital content is a firehose, and Lilys AI is essentially the high-performance filter we’ve all been waiting for. If you’ve ever stared at a two-hour YouTube podcast or a 50-page PDF with a sense of impending doom, this tool is designed for you.

Lilys AI (lilys.ai) has evolved significantly in early 2026, transitioning from a simple YouTube summarizer into a robust multimodal research and productivity hub. It is designed to solve “information obesity” by distilling massive amounts of video, audio, and text into structured, actionable insights.

What is Lilys AI?

Lilys AI is an AI-powered summarization and research workspace. While many tools simply “summarize,” Lilys AI focuses on source-grounded intelligence. It doesn’t just tell you what happened; it shows you exactly where in the video or document the information lives, using sentence-level citations and timestamps.

Core Capabilities

• YouTube Mastery: Turn any video link into a structured report with timestamps and screenshots.
• Multimodal Ingestion: It processes YouTube links, local video/audio files, PDFs, websites, and raw text.
• Visual Thinking: Beyond bullet points, it can generate mind maps, infographics, and diagrams to help you visualize complex topics.
• Multi-Language Support: Supporting over 50 languages, it can summarize a foreign-language lecture into your native tongue with surprising nuance.

Key Features & 2026 Updates

1. Multimodal Input Support

While it gained fame for its YouTube summarization, Lilys AI now processes a wide array of sources:

• Video & Audio: Direct links or file uploads (MP4, MP3, WAV). It provides real-time transcription and translation in 50+ languages.
• Documents: PDFs (including complex academic papers), DOCX, and plain text.
• Web Clipper: A dedicated Chrome extension that “scraps” and summarizes articles or entire websites with one click.

2. Advanced Visual Outputs

Unlike text-only competitors, Lilys AI offers diverse visual formats to suit different learning styles:

• Mind Maps: Automatically generates hierarchical diagrams to show how ideas connect.
• Infographics: Uses the Nano Banana (Gemini 2.5 Flash) model to create visual summaries suitable for social media or presentations.
• Timeline Notes: Perfect for historical content or project meetings, organizing information chronologically with timestamps.
• Quiz Generation: Turns any source into a set of flashcards or multiple-choice questions for active recall.

3. “DeepSearch” & Source Grounding

To combat AI hallucinations, Lilys AI introduced DeepSearch. This feature:

• Provides sentence-level citations that link directly to the exact second in a video or the specific line in a PDF.
• Cross-references information with external trusted sources to verify facts.
• Uses “Deep Insight” reports to move beyond simple summaries and offer critical analysis and “Explain Like I’m 5” (ELI5) modes.

Most summarizers give you a generic “TL;DR.” Lilys AI provides a hierarchical breakdown. You get a high-level summary, followed by detailed sections with bolded key terms. If a point interests you, you can “unfold” the original script to verify the context instantly.

Once a report is generated, you can use the Lily AI Assistant to ask follow-up questions.

Example: “Based on this hour-long interview, what were the three specific mistakes the founder made in their first year?”

Advanced Workflows

• The “Notion Sync”: Many users leverage Lilys AI to summarize a 3-hour podcast, generate a mind map, and then export the entire structured note directly into their Notion Second Brain for long-term storage.
• Foreign Language Research: You can input a Korean tech vlog or a German research paper; the AI will summarize it in English (or your preferred language) while maintaining the original context.
• Agentic Chat: The “Lily” assistant isn’t just a chatbot—it’s an agent. You can ask it to “Extract all mentions of $X$ variable and format them into a table,” or “Rewrite this summary into a 5-tweet thread.”

Lilys AI vs. NotebookLM

While Google’s NotebookLM is excellent for grounded research on uploaded documents, Lilys AI excels in web-first workflows. It is significantly faster at handling YouTube URLs and provides more varied output formats (like timelines and infographics) compared to NotebookLM’s focus on “Deep Dives” and Audio Overviews.

Note on Confusion: Ensure you are using lilys.ai. There is a separate company called Lily AI (lily.ai) that focuses on retail e-commerce data. Lilys AI (with the “s”) is your productivity companion.

Who is Lilys AI for?

• Students & Researchers: Turn a semester’s worth of recorded lectures into a searchable, cited knowledge base.
• Content Creators: Quickly extract the “meat” of a competitor’s video to find gaps or inspiration for your own scripts.
• Business Leaders: Digest industry webinars and 1:1 meeting recordings without losing hours to playback.
• Curious Minds: Keep up with podcasts like Huberman Lab or Lex Fridman by reading the key takeaways in 5 minutes.

The Verdict

Lilys AI is a “quality-first” summarizer. Its greatest strength is transparency—the fact that every claim is linked to a timestamp or a specific line in a PDF makes it much more reliable than a standard chatbot that might “hallucinate” details.

If you prefer visual learning, the Mind Map feature alone makes it worth a try. It transforms a linear video into a web of ideas, which is significantly better for long-term retention.
