The Problem

Most YouTube tools show you numbers. Few actually analyze the content.

You can see a competitor’s view counts. You can read their titles. But why are some YouTube videos getting views and others aren’t? What’s different about the hook, the pacing, the thumbnail? Finding out takes hours of manual watching and note-taking — per channel.

The problem isn’t data. It’s that most tools still don’t analyze the actual video content — the hooks, the pacing, the visual storytelling.

Contentine uses Gemini’s multimodal AI to watch videos frame by frame — then gives you a structured breakdown of hooks, pacing, thumbnails, and content strategy across an entire channel.

What Makes It Different

AI video analysis from watching, not scraping.

AI watches the actual video.

Most YouTube tools focus on metadata — titles, tags, and descriptions. Contentine sends video frames directly to Gemini multimodal AI for deep hook analysis, thumbnail analysis, and pacing analysis — the things that actually make people click and stay.

Per-video breakdown + channel-wide strategy.

Every video gets its own detailed report — hook quality, thumbnail effectiveness, content structure, strengths, and areas to improve. Then you get a channel-level synthesis of patterns across all analyzed videos.

Bring your own API key — or don’t.

Power users can connect their own Gemini API key for unlimited free-tier usage. Everyone else can use Quick Mode with credit-based pricing — starting at ~$0.10 per video. Switch anytime.

Not an SEO tool. Not a dashboard. A content microscope.

TubeBuddy and VidIQ optimize keywords and tags. Social Blade shows subscriber graphs. Contentine goes deeper — it watches the actual video content with AI and produces structured reports on what’s working and why.

Choose your model, resolution, and depth.

Pick from 15+ Gemini models — fast and cheap or deep and thorough. Control video resolution quality. See estimated costs before you start. You’re always in control.

Common Questions

Before you ask.

Yes, you need an account. You get free trial credits to start — enough to analyze a few videos and see what the tool does. Sign up is quick, and you can also bring your own Gemini API key (BYOK) for unlimited free use.

Yes. Contentine uses the official YouTube Data API for video discovery and publicly available video content for AI analysis — the same information any viewer can access. No private data is accessed, no login credentials are required, and no platform terms are violated.

Those tools focus on SEO optimization — keywords, tags, and search rankings for your own channel. Contentine is fundamentally different: it uses AI vision to watch actual video content, analyze visual and editorial patterns, and tell you why certain videos perform. They optimize metadata. We analyze content.

Two paths. Quick Mode: pay-as-you-go credits starting at ~$0.10 per video, with free trial credits to start. BYOK Mode: bring your own free Gemini API key from Google and pay nothing. The cost estimator shows exactly what each analysis will cost before you start. You choose the Gemini model and resolution — cheaper models cost less, premium models cost more.

Contentine sends each video — including thumbnails and video frames at your chosen resolution — to Google’s Gemini multimodal AI. The model processes the visual and audio content just like a human viewer would, then returns a structured analysis of hooks, pacing, presentation style, content structure, and more. It’s not reading metadata or scraping descriptions — it’s watching the actual content.

Both are in active development. Analyze is available now as the foundation of the Contentine pipeline. Enter your email in the notify form on this page to get early access to Brief and Create when they launch.

Yes. Since the AI watches the actual video content rather than relying on engagement metrics, it works just as well on a 500-subscriber channel as a 5M one. Niche channels often produce the most actionable insights because their content patterns are more focused.

Each video analysis includes 20+ data points — hook effectiveness, thumbnail composition, pacing patterns, content structure, presentation style, audience targeting, and specific improvement suggestions. The channel report synthesizes cross-video patterns. Even experienced creators consistently find insights they missed.

Privacy & Transparency

Your data stays yours.

Contentine uses publicly available YouTube data and Google’s Gemini AI to analyze video content. It does not access private accounts or require any YouTube login credentials. BYOK users connect their own Google API keys directly — your keys never leave your browser. Contentine is not affiliated with, endorsed by, or connected to YouTube or Google.
