This comprehensive comparison with real screenshots will help you choose the right tool for your workflow. Updated December 2025.
Clean web interface focused on comprehensive summarization. Input any YouTube URL, choose from 111 languages, select a template, and get detailed summaries with AI chat capability.
Chrome extension that adds a sidebar directly to YouTube. Get 8 key ideas in 5 seconds with timestamped navigation to jump to specific topics. Mobile apps available for on-the-go access.
Eightify's approach: Built for speed and convenience. The Chrome extension integrates directly into YouTube, giving you instant access to summaries without leaving the video page. Their "8 key ideas in 5 seconds" positioning is perfect for rapid content scanning. The mobile apps (iOS + Android) extend this convenience to your phone.
AI Vid Summary's approach: Designed for depth and customization. The web interface may require an extra tab, but it offers comprehensive summaries with full paragraph context, custom template options, and 111-language translation. The AI chat feature lets you dig deeper into any topic mentioned in the video.
Verdict: Choose Eightify if you want seamless YouTube integration and rapid scanning. Choose AI Vid Summary if you need comprehensive summaries with translation, custom templates, and deeper analysis through AI chat.
AI Vid Summary supports 111 languages for both input and output, while Eightify supports 40+ languages. This difference matters significantly for multilingual research and global content consumption.
Comprehensive Global Coverage
Supports 111 languages including regional variants, minority languages, and emerging markets.
Bidirectional Translation
Watch a Japanese video, get a summary in Spanish. Watch an English video, get a summary in Hindi. Any combination works.
AI Chat in Your Language
Ask follow-up questions about the video in any of the 111 supported languages.
Major Languages Covered
Supports 40+ major world languages including English, Spanish, French, German, Japanese, Chinese, etc.
Translation Available
Can translate summaries into supported languages for global accessibility.
Focused on Popular Languages
Prioritizes major languages with large user bases rather than comprehensive coverage.
Real-world example: A crypto researcher using AI Vid Summary can watch a Korean crypto analyst's video (Korean audio), get the summary in English, then ask follow-up questions in Spanish to share with their Latin American team. Eightify would handle the Korean-to-English part well, but the 111-language coverage gives AI Vid Summary more flexibility for global teams.
AI Vid Summary lets you create custom templates from scratch to extract exactly what you need. Eightify provides a standardized "8 key ideas" format, which works well for general use but cannot be customized.
Sales Team Template for Product Demo Videos:
Standard Output for All Videos:
Simple, fast, but not adaptable to specific workflows.
Sales Team Template:
Extract: Pricing mentioned, competitor names, pain points discussed, feature requests, objections raised. Format as categorized bullet points for CRM entry.
Academic Research Template:
Extract: Methodology, data sources, key findings, limitations, future research directions. Format with citations and timestamps for literature review.
Content Creator Template:
Extract: Viral moments (with timestamps), thumbnail ideas, hook strategies, engagement tactics, audience comments sentiment. Format for content repurposing.
Market Research Template:
Extract: Market size claims, growth projections, customer segments mentioned, competitive landscape, trends identified. Format as market intelligence brief.
Developer Tutorial Template:
Extract: Prerequisites, step-by-step commands (with timestamps), code snippets, common errors, dependencies. Format as implementation checklist.
Executive Briefing Template:
Extract: Key decisions, action items, strategic implications, risks mentioned, ROI data. Format as one-page executive summary.
Why this matters:
Eightify's "8 key ideas" format is excellent for general consumption—you get the highlights fast. But if you're a researcher who needs methodology details, a salesperson who needs pricing mentions, or a developer who needs step-by-step commands, AI Vid Summary's custom templates extract exactly what you need in the format you want.

AI Vid Summary |
Interpretation: AI Vid Summary wins on depth, customization, and global features (languages, templates, AI chat). Eightify wins on speed and convenience (Chrome extension, mobile apps, comment analysis). Your choice depends on whether you prioritize comprehensive analysis or rapid scanning.
Everything you need to know to make the right choice for your workflow.
Eightify is significantly faster — it generates summaries in ~5 seconds optimized for rapid scanning. AI Vid Summary takes ~60 seconds because it creates more comprehensive summaries with full context. If you're scanning dozens of videos quickly, Eightify wins. If you need depth and understanding, AI Vid Summary's extra time delivers better insights.
Yes. AI Vid Summary is entirely web-based — just paste any YouTube URL and get your summary. Eightify requires a Chrome extension that integrates directly into YouTube's interface. If you prefer not installing extensions or use browsers other than Chrome (Firefox, Safari, Edge), AI Vid Summary is your better option.
It depends on your use case. If you only watch English content, 40+ languages is plenty. But if you're a researcher tracking global trends, a crypto analyst monitoring Korean/Japanese channels, or a multilingual professional working with international teams, AI Vid Summary's 111 languages becomes essential. You can watch a video in one language and get the summary in another — including minority languages Eightify doesn't support.
Eightify has dedicated mobile apps for iOS and Android, which is a significant advantage if you summarize videos on your phone. AI Vid Summary works on mobile browsers (responsive web design) but doesn't have native apps yet. If mobile convenience is critical, Eightify wins here.
No. Eightify always delivers "8 key ideas" in a standardized format. This consistency is great for rapid consumption but lacks flexibility. AI Vid Summary offers 12 preset templates (study notes, blog posts, meeting minutes, etc.) plus the ability to create custom templates from scratch. If you need summaries formatted for specific workflows (CRM entry, academic citations, code documentation), AI Vid Summary is your only option.
It depends on your tools: If you use Notion, AI Vid Summary has one-click export (Eightify requires manual copy-paste). If you spend your day on YouTube, Eightify's Chrome extension sidebar is more convenient. If you process entire playlists, AI Vid Summary's batch processing saves hours. If you want to ask follow-up questions about the content, only AI Vid Summary has AI chat.
Yes, both tools offer free plans. AI Vid Summary lets you use it without signup OR create a free account for higher daily limits (no credit card required). Eightify also has a free tier with usage limitations. Both are generous enough to test thoroughly before committing to a paid plan.
Eightify's biggest strengths are speed (5-second summaries), convenience (Chrome extension sidebar on YouTube), mobile apps (iOS + Android), and comment analysis (see what other viewers think). If you're a power user who scans 20+ videos daily and wants the fastest possible workflow, Eightify is built for you.
Absolutely! Many users do exactly this: Eightify for rapid scanning (quickly filter through videos to find what's worth watching) and AI Vid Summary for deep analysis (comprehensive summaries with custom templates and AI chat for important content). Use Eightify's free plan to scan, then upgrade AI Vid Summary for deep dives.
Both tools are excellent — the question is which workflow fits you better.
Free forever • No credit card required • 40% student discount
Free tier available • Chrome extension required
Pro tip: Many power users use both tools together — Eightify for rapid scanning and AI Vid Summary for deep dives on important content. Start with the free plans to find what works for you.
