What's New in NotebookLM 2026?

Quick Answer: NotebookLM 2026 introduces Slide Editing, Data Tables, Custom Personas, Deep Research, and a 1M token context window — making it a powerhouse for document analysis. However, it remains primarily focused on text/PDF inputs, with limited multi-platform video processing capabilities.

As of March 2026, NotebookLM has rolled out five major features:

• Slide Editing: Create and edit presentation slides directly within notebooks
• Data Tables: Extract structured data and generate tables from sources
• Custom Personas: Customize AI response styles for specific domains
• Deep Research: Cross-document analysis and deep investigation workflows
• 1M Token Context: Process massive documents with a million-token context window

These updates solidify NotebookLM as a powerful research tool. But if your primary learning materials are videos — YouTube tutorials, online courses, podcasts, or meeting recordings — you may need a different solution.

BibiGPT's Unique Strengths

Quick Answer: BibiGPT is an AI-powered audio-video content tool trusted by over 1 million users with over 5 million summaries generated, supporting 30+ platforms including YouTube, Bilibili, TikTok, and podcasts for one-click video summarization.

While NotebookLM excels at document analysis, BibiGPT solves a different core challenge: How do you efficiently digest audio-video content scattered across dozens of platforms?

30+ Platform Support

Simply paste a video URL, and BibiGPT generates a timestamped, structured summary within 30 seconds. Whether it's YouTube, Bilibili, TikTok, Douyin, or any podcast — everything is processed through one unified interface. Explore the AI YouTube video summary feature.

Subtitle Download & Transcription

BibiGPT includes built-in video subtitle extraction and download supporting multi-language subtitle export in SRT, TXT, and more. For videos without subtitles, it offers AI speech-to-text engines including ElevenLabs Scribe.

Note Export Ecosystem

Summaries sync to Notion, Obsidian, Readwise, Cubox, and 10+ knowledge management tools — turning video content into searchable, lasting knowledge.

Feature-by-Feature Comparison

Quick Answer: NotebookLM excels at deep document analysis (PDFs, text, web pages), while BibiGPT excels at multi-platform audio-video processing (30+ video platforms). They complement rather than compete with each other.

Hands-On Test Experience

We compared both tools processing the same YouTube tutorial: NotebookLM requires uploading the video transcript as a notebook source to indirectly process video content, while BibiGPT generates timestamped structured summaries directly from the URL. For Bilibili and podcast content, NotebookLM cannot process these platform links directly, while BibiGPT handles them seamlessly.

Step-by-Step: How to Summarize Videos with BibiGPT

Quick Answer: Summarizing videos with BibiGPT takes just three steps: paste a link, wait for processing, and view/export results. Supports Chinese, English, Japanese, and Korean output.

1. Open BibiGPT: Visit aitodo.co or launch the desktop/mobile client
2. Paste a Video URL: Enter any platform video link in the homepage input
3. Get Structured Summary: The system automatically extracts subtitles, generates summaries, and annotates timestamps
4. Deep Interaction: Click timestamps to jump to video moments, or use AI chat to ask follow-up questions
5. Export Notes: One-click sync to Notion, Obsidian, or export as Markdown/PDF

For batch processing, use the multi-link batch summary feature to process multiple videos at once.

FAQ

Q1: Can NotebookLM summarize Bilibili videos?

A: Currently, NotebookLM does not directly support Bilibili video links as input sources. You would need to manually obtain the video transcript first. BibiGPT can directly paste a Bilibili link for one-click summarization.

Q2: Does BibiGPT have deep research features like NotebookLM?

A: BibiGPT offers Collection Summary and Collection AI Chat features for cross-video Q&A and comparative analysis. While the approach differs from NotebookLM's multi-document research, it achieves similar depth for video-based learning scenarios.

Q3: Can I use both tools together?

A: Absolutely. Recommended workflow: First summarize videos with BibiGPT and export as Markdown, then import the text into NotebookLM alongside other documents for deep research. This leverages the strengths of both tools.

Q4: Does BibiGPT use the same AI model as NotebookLM?

A: No. NotebookLM is powered by Gemini, while BibiGPT supports multiple advanced AI models that users can freely switch between to get the best summarization results for their needs.

Conclusion

NotebookLM 2026's upgrades make it a formidable tool for document analysis, while BibiGPT continues to lead in audio-video content processing. They are complementary, not competitive. If you are a video learner or need to process multi-platform audio-video content, BibiGPT is your essential learning companion.
