Top 5 AI Audio & Video Summary Apps in 2024

Feeling overwhelmed by lectures, podcasts, and webinars? AI-powered summarizers can turn hour-long recordings into concise notes. We tested the standouts of 2024 and ranked them for different use cases—creators, professionals, and lifelong learners.

BibiGPT: The All-in-One Media Learning Assistant

BibiGPT ingests links from Bilibili, Xiaohongshu, YouTube, Xiaoyuzhou, Douyin, or local files, then delivers:

• Watch faster – AI summaries, chapters, bilingual subtitles, mind maps.
• Find smarter – Search inside transcripts, ask follow-up questions, explore highlight cards.
• Use better – Export to Notion, Obsidian, Logseq, Readwise, and more.

Power users can add custom prompts for specialized output or pair BibiGPT with spaced repetition (see our BibiGPT + Anki workflow). The learning curve is slightly higher, but the feature set is unmatched.

MemoAI: Local Transcription with Live Notes

MemoAI focuses on privacy and precision:

• Real-time subtitles with floating notes
• Local processing for MP4, MP3, AAC, and more (especially fast on Apple Silicon)
• Quick clipping and segment-based exports

Ideal when you already have the media file and prefer on-device processing. Fetching web audio still takes extra steps, but transcription quality is top-tier.

Recall: Build a Personal Knowledge Graph

Recall is more than a summarizer—it captures articles, videos, and PDFs into a searchable knowledge graph. Automatic enrichment, backlinks, and concept maps reveal relationships across your saved content. Perfect for researchers who want to connect the dots, not just skim.

Podwise: Podcast Summaries for Busy Listeners

Podwise pulls episodes directly from RSS feeds, highlights takeaways, and surfaces quotes and timestamps. Use it to triage long episodes before committing to a full listen—or to archive the shows you already love.

Alibaba Tingwu: Enterprise-Ready Meeting & Course Companion

Tingwu handles live meetings, cloud recordings, and course videos in Chinese and English. Features include real-time transcription, multi-speaker recognition, and enterprise dashboards. It’s a natural fit for teams already in the Alibaba Cloud ecosystem.

Which One Should You Choose?

Each app targets a different problem—pick the one that aligns with your workflow. And remember: as models like GPT-4o, Claude 3.5, and Gemini Pro keep improving, expect even smarter media workflows ahead. We’ll keep testing and reporting on the tools that help you learn faster.
