The 11 Best YouTube Summarizers in 2026
Every major tool compared on speed, pricing, languages, and what makes each one worth (or not worth) your time.
Short answer: PeekaTube is the best overall pick if you want summaries that include what viewers think, in 10+ languages. Eightify is the fastest for timestamped bullets. NoteGPT is best for mind maps and study tools. Glasp is the best fully free option. The ranking below explains each pick.
Disclosure: PeekaTube is our product. We rank it first because of the integrated comment analysis no other tool offers, but every entry includes an honest "best for" verdict and a link to a detailed head-to-head comparison so you can judge for yourself.
1. PeekaTube
Best For: Deep research, multilingual, full video understanding with comments · Pricing: $5.99/mo
PeekaTube generates a structured summary (Summary, Notes, Quotes) in about 7 seconds and is the only tool on this list that integrates YouTube comment analysis into the summary itself, so you see what the video says and how viewers reacted in one view. It translates summaries into 10+ languages (for example, a Chinese summary of a Japanese video) and includes full transcript access and one-click export. Pro costs $5.99/mo or $29.99/yr, with 3 free trial summaries for new visitors.
2. Eightify
Best For: Quick timestamped previews · Pricing: $4.99/mo
Eightify is one of the fastest YouTube summarizers at about 5 seconds, delivering clean timestamped bullet points. It's used by 100,000+ users daily and also offers a "Top Comments Overview" feature for comment sentiment. Eightify supports 40+ output languages and is available on Chrome, Safari, iOS, and Android. At $4.99/month ($59.99/year), it's competitively priced but has a very limited free tier — only 3 summaries total, restricted to videos under 30 minutes.

Best For: Note-taking & mind maps · Pricing: Free / Paid tiers
NoteGPT is an all-in-one AI learning assistant combining video summarization with mind maps, AI chat, note-taking, and even AI presentations. It handles videos without subtitles (up to 150 minutes), supports batch summarizing up to 20 videos, and uses ChatGPT 4 and Claude 3. The free tier gives 15 quotas per month. However, the interface feels cluttered with features, and it doesn't analyze viewer comments.

Best For: Free power users who want model choice · Pricing: Free / $8.99/mo Pro
Glasp is the most popular YouTube summarizer with 2M+ users and a truly generous free tier — unlimited desktop summaries at no cost. It supports multiple AI models (ChatGPT, Claude, Gemini, Mistral) and works on articles and PDFs too. The Pro plan ($8.99/month) adds mobile access. The trade-off: summary quality varies by model, there's no comment analysis, and no built-in cross-language translation.

Best For: Multi-source research & audio overviews · Pricing: Free / $19.99/mo
NotebookLM is Google's AI research assistant — not a YouTube extension, but a multi-source research platform. You add YouTube URLs alongside PDFs, Google Docs, and audio files, then interact with all of them as a unified knowledge base. It generates Audio Overviews (podcast-style discussions) and Video Overviews of your sources. The free tier is generous (50 sources per notebook, 25 audio overviews/day), with Plus at $19.99/month via Google One AI Premium. NotebookLM is built for deep, multi-document research — not quick video previews.

Best For: Content repurposing & no-subtitle videos · Pricing: $9.99/mo
TubeOnAI is a versatile summarizer that works on videos without transcripts by processing audio directly. It claims 99% accuracy and offers 130+ templates for repurposing summaries into blog posts, social media content, and newsletters. Available on web, Android, and iOS. However, at $9.99/month ($20/month after the first month for Pro), it's one of the most expensive options and doesn't offer comment analysis.
Read the full comparison →7. Notta
Best For: Meeting transcription (YouTube is secondary) · Pricing: $8.25/mo
Notta is primarily an AI meeting transcription platform (Zoom, Google Meet, Webex) that also supports YouTube video summarization as a secondary feature. It supports 58 transcription languages and 42 translation languages with 98.86% accuracy. The Chrome extension generates summaries directly while watching. However, the free tier is extremely limited — only 1 YouTube video total — and the pricing reflects its meeting-focused feature set.
Read the full comparison →8. QuickerAI
Best For: Speed-focused summaries · Pricing: Free / Paid
QuickerAI markets itself as one of the fastest summarizers (claiming '3x faster than alternatives') with instant key points and multilingual support. It's lightweight and focused purely on speed. However, it lacks comment analysis, transcript access, and export features — making it best for quick, disposable summaries.

Best For: Bookmarking + summarizing · Pricing: $5.99/mo
Kome AI combines summarization with bookmarking and AI-assisted writing. It works on articles, news, YouTube videos, and websites. It also includes a color palette extractor and content generation from bookmarks. Available across Chrome, Firefox, Edge, Opera, and Brave. However, user reviews report reliability issues — the extension sometimes stops working, shortcuts fail, and subscription management can be frustrating.

Best For: Simple, free one-click summaries · Pricing: Free
Clarify AI is a Gemini-powered summarizer that offers completely free, simple one-click summaries in about 5 seconds. No account required. It's the simplest option for casual users who want a basic overview without paying. However, it lacks comment analysis, multilingual output, transcript access, and export — just the bare-minimum summary.
Read the full comparison →11. DeArrow
Best For: Removing clickbait titles/thumbnails · Pricing: $1 (one-time)
DeArrow takes a completely different approach — it replaces clickbait titles and thumbnails with community-submitted alternatives. It doesn't summarize content at all. Crowdsourced titles are voted on by users, and when no submission exists, it auto-formats the original title and picks a random non-sponsor video frame as the thumbnail. It's a great complement to PeekaTube, not a replacement.
Read the full comparison →How we ranked
Each tool was evaluated on five criteria: summary speed, pricing and free tier, output languages, whether it analyzes YouTube comments, and export or transcript access. Data comes from our hands-on testing for the head-to-head comparison pages and is refreshed with each site update.
What is the best free YouTube summarizer?
Glasp is the best fully free YouTube summarizer, though you manage your own AI model choices. DeArrow is essentially free ($1 one-time) but replaces clickbait titles rather than summarizing. PeekaTube offers 3 free trial summaries without an account.
What is the best YouTube summarizer for non-English videos?
PeekaTube. It summarizes videos in any source language and outputs summaries in 10+ languages, including English, Traditional Chinese, Korean, Japanese, and Spanish. Most alternatives only summarize into the video's original language or English.
Which YouTube summarizer also analyzes comments?
Only PeekaTube integrates viewer comment insights directly into the summary. Eightify offers a separate top-comments overview, but no other tool combines video content and audience reaction in one summary.
