YTubViral: YouTube SEO, Analytics & AI Tools

Free YouTube SEO tools: SEO Score on every video, keyword research, competitor analytics & AI titles — inside YouTube & Studio.

Stop switching tabs. YTubViral is a free YouTube SEO and analytics toolkit that lives right inside YouTube — an instant SEO score on every video, keyword research on every search, competitor analytics on every channel, plus outlier detection and AI title generation, all while you browse YouTube and YouTube Studio. Powered by Claude (Anthropic's AI) — not generic GPT. Whether you're growing your first channel or you're an experienced creator looking for an edge, YTubViral puts the YouTube optimization data you need exactly where you need it — without ever leaving YouTube. ────────── ONE PANEL — ON EVERY YOUTUBE PAGE ────────── YTubViral adds a single panel, docked to the right edge of every YouTube and YouTube Studio page. Click the tab to open it. It has four tabs: • This page — shows whatever is relevant to where you are: the full SEO scorecard on a video or Short, keyword competition and opportunity data on a search, a one-click breakdown on a channel page. • Your channel — your subscriber and view counts, 7- and 30-day growth, monetization progress with an ETA, and a personalized best-time-to-post recommendation. Available from any page, not just Studio. • Ideas — 5 personalized video ideas for the day, if you've connected your channel. • Coach (Pro) — a Claude chat that knows what you're looking at. Ask it about the video, the channel, or your strategy. One consistent place — no hunting for panels that appear and disappear. ────────── SEO SCORE — ON EVERY VIDEO ────────── On any watch page or Short, the "This page" tab shows a full scorecard: • SEO Score ring (0–100) — instant quality check for title, description, tags, and thumbnail • Detailed checklist + Quick Wins — exactly what's missing and how many points each fix is worth • Views per hour (VPH) — how fast the video is gaining traction right now (recent velocity, not just a lifetime average) • Engagement rate and likes ratio • Outlier detection — a pulsing badge appears when a video has 5x+ its channel's average views. Spot viral content instantly. Works without an account. The SEO Score, VPH and outlier detection load on any video or Short even before you sign in (anonymous requests are limited by volume). A free account adds keyword research, comment sentiment, your channel stats and 10 AI generations a month. ────────── VELOCITY BADGES & HOVER STATS ────────── On the YouTube homepage, search results, and the suggested-videos sidebar, every thumbnail gets a small VPH (views per hour) badge — no account needed. Hover any thumbnail and a card expands with views, likes, comments, engagement rate, the channel's subscriber count, and age — reusing the same data, no extra loading. The extension fetches public view counts and publish dates from the YouTube Data API to calculate velocity. Badges load as you scroll — no performance impact. ────────── YOUTUBE STUDIO INTEGRATION ────────── YTubViral works inside YouTube Studio too — no need to switch to another site to check your SEO: • Video list — SEO Score badges appear next to each video title. See at a glance which videos are well-optimized and which need work. • Video editor — a live SEO panel sits right next to the title field, with a score ring, optimization checklist, and outlier badge. As you edit your title, description, and tags, the score updates in real time. • Upload dialog — the same live panel appears while you're uploading a NEW video, so you optimize the title, description, and tags before you hit publish — when it matters most. • A/B test titles without leaving Studio (Pro) — next to every AI-generated title suggestion in the editor, hit "A/B" to automatically start a real title test on your published video: YTubViral rotates your current title against the suggestion and tells you which one wins with real view data. Not even the big analytics extensions offer this. • Best time to post — a personalized hint (based on your channel's own audience activity) appears in both the editor and the upload dialog. • AI tag suggestions — click "Suggest tags" and the extension searches for keywords related to your video title, then displays clickable tag pills you can copy into your tag field. ────────── KEYWORD RESEARCH — FOR EVERY SEARCH ────────── Search anything on YouTube and open the panel — the "This page" tab shows real data for that keyword: • Competition level — Low / Medium / High. Instantly know if a keyword is dominated by big channels or if there's room for a newcomer to rank. • Opportunity Score (0–100) — a combined metric that weighs competition against demand. Above 70 means the keyword is worth targeting. • Total results — how many videos compete for this term. • Average views of the top videos — tells you if there's real audience demand. • Related search terms — click any suggestion to immediately search it on YouTube and see its own stats. Perfect for finding keyword variations you hadn't thought of. ────────── COMPETITOR CHANNEL ANALYSIS (Pro) ────────── On any YouTube video page or channel page, one click pulls up a full audit: • Subscribers, total views, upload frequency, and estimated monetization • Top videos by views — thumbnail, title, and age, so you see exactly which content is working • Title patterns — average length, % with a number, % with a question/hook, % using brackets, computed from their own top videos • Recurring keywords from their last 30 videos — click any to search it on YouTube • "Why does this work?" — one click and Claude explains the pattern behind their top content, instead of just listing the data ────────── COMMENT SENTIMENT ANALYSIS ────────── On any video page, the extension can analyze the top comments and show: • Sentiment breakdown — positive, negative, and neutral percentages with a visual bar • Top comments by likes — the most engaged-with responses • Questions from viewers — surfaced separately, with one-click AI-drafted replies ────────── AI-POWERED CONTENT GENERATION ────────── Watching a video and getting inspired? Click "Generate titles" and get 5 viral title options for a similar topic — without leaving YouTube. In YouTube Studio, the AI can also: • Generate SEO-optimized descriptions based on your video title • Suggest tags by searching for related keywords automatically • Generate replies to viewer comments Content is generated by Claude (Anthropic's AI), the same model powering ytubviral.com — titles land in the 40–60 character CTR sweet spot, use action verbs, and stay honest rather than clickbait. Free users get 10 AI generations per month across the extension and the web app combined. Pro users get 200. Business users get unlimited. ────────── AI COACH — INSIDE YOUTUBE (Pro) ────────── The "Coach" tab is a Claude chat that already knows two things: your channel, and whatever you're looking at right now — the video on screen, the channel page, or your last search. Ask "what would you change about this title?" or "is this a good topic for my channel?" and it answers about that specific thing, with your channel's real data behind it. vidIQ's coach only knows your own channel. This one reasons about the page in front of you. ────────── PART OF THE YTUBVIRAL ECOSYSTEM ────────── The extension is a companion to ytubviral.com — a full AI content suite for YouTube creators: • Full video scripts (complete scripts with intro, sections, and outro) • SEO-optimized descriptions with timestamps • Captions and hashtags for social media • Video concepts and thumbnail ideas • Hook lines for the first 15 seconds • A/B testing for titles and thumbnails • Trending video explorer with filters by country, language, duration, and category • Revenue estimator, retention analyzer, and more The extension puts the most time-sensitive features (SEO scoring, keyword research, competitor data, outlier detection) right where you need them — in YouTube itself. For deeper content creation, the web app has you covered. ────────── HOW IT WORKS ────────── 1. Install the extension — click "Add to Chrome" above. 2. Open the YTubViral panel — click the tab on the right edge of any YouTube page. On a video or Short, the SEO scorecard loads straight away — no account needed. 3. Connect your account for everything else — click the YTubViral icon and sign in with your ytubviral.com account. Or, if you signed up with Google, just open ytubviral.com while logged in and the extension connects automatically — no password needed. Creating an account is free (no credit card required). Once connected, the toolbar popup becomes a mini dashboard — this week's subscriber and view gains, plus the day's ideas. 4. Browse YouTube normally. The "This page" tab always reflects where you are, "Your channel" and "Ideas" are one click away, thumbnails get velocity badges as you scroll, and in YouTube Studio the live SEO panel sits next to the title while you edit or upload. ────────── PLANS & LIMITS ────────── Free plan (no credit card): - SEO scorecard on any video or Short (no account needed for the basics) - Velocity badges on all thumbnails - Unlimited keyword research - Comment sentiment analysis - Your channel stats, growth and best time to post - 10 AI generations per month (titles, descriptions, tags, comment replies) — shared with the web app Pro plan — 9.99 EUR/month or 99.99 EUR/year: - Everything in Free - 200 AI generations per month - Competitor channel analysis - A/B testing for titles, straight from YouTube Studio - AI Coach chat inside YouTube - Full access to all web app tools Business plan — 29.99 EUR/month or 299 EUR/year: - Everything in Pro - Unlimited AI generations - Team collaboration (up to 5 members) - Priority support ────────── PRIVACY & DATA HANDLING ────────── The extension requests the "storage" permission and access to three domains: youtube.com, studio.youtube.com, and ytubviral.com. It does not run on any other website. Data the extension collects and transmits to ytubviral.com over HTTPS: • Login credentials — if you sign in via the extension popup, your email and password are sent to ytubviral.com to authenticate you. They are not stored locally; only the resulting session token is kept in chrome.storage.local. • Session-based connection (no password) — alternatively, when you are logged into ytubviral.com in your browser, the extension can obtain an authentication token from your existing ytubviral.com session over HTTPS. This lets Google sign-in users (who have no password) connect. Only the resulting token is stored in chrome.storage.local. • Authentication token — stored locally in chrome.storage.local to keep your session active. • Language preference — stored locally in chrome.storage.local ("es" or "en"). • Local UI state — a count of how many times you've opened the scorecard, a flag for whether a review prompt has been shown, and the open/closed state and last-used tab of the panel — all stored only in chrome.storage.local. They never leave your device. • YouTube video IDs — when you visit a video or a Short, open YouTube Studio, or scroll past thumbnails on the homepage or search results, the extension sends video IDs to ytubviral.com to retrieve SEO scores, statistics, and views-per-hour velocity data. This happens whether or not you have an account; anonymous requests are rate-limited by IP address. Video IDs are public identifiers, not private data. • YouTube search queries — when you search on YouTube and open the panel, the search term is sent to ytubviral.com to return competition, opportunity scores, and related keywords. • YouTube channel identifiers — when you view a channel page or use the competitor analysis feature, the channel URL or ID is sent to ytubviral.com to fetch public channel statistics. • YouTube Studio draft metadata — when you edit a video in YouTube Studio, the extension reads your draft title, description, and tags from the editor fields and sends them to ytubviral.com for live SEO scoring. This data is processed in real time and not stored on our servers. • Your own channel stats — the "Your channel" tab displays your channel's subscriber count, view count, growth trends, monetization progress, and a personalized best-time-to-post recommendation, fetched from ytubviral.com using your authenticated session. • Daily video ideas — if you have connected a YouTube channel, the "Ideas" tab fetches up to 5 personalized video ideas per day from ytubviral.com, cached locally for the day to avoid repeat requests. • AI Coach messages (Pro) — when you use the "Coach" tab, your typed messages, the conversation so far, and a short note of what you're viewing (a video title, a channel URL, or a search term) are sent to ytubviral.com to generate a reply. The conversation is not stored on our servers. Without an account, the SEO scorecard still works: the extension sends the video ID (a public identifier) to ytubviral.com to compute the score, rate-limited by IP address. If that request is unavailable, it falls back to a title-only score (length, keywords, hook words, formatting) computed locally on your device and never transmitted. Data the extension does NOT collect: • Your browsing history outside the three domains listed above. • Your Google account credentials or YouTube login. • Your watch history or YouTube recommendations. • Any data from websites other than youtube.com, studio.youtube.com, and ytubviral.com. On ytubviral.com itself, a minimal script (detect.js) sets a data attribute on the page so the website can detect the extension is installed (e.g., to show or hide an "Install extension" banner). In addition, if you are logged into ytubviral.com and the extension is not yet connected, this script requests an authentication token from your session over HTTPS and passes it to the extension (the session-based connection described above). It communicates only with ytubviral.com. All data is transmitted exclusively to ytubviral.com over HTTPS. No data is shared with third parties. You can delete all locally stored data by logging out from the extension popup or by uninstalling the extension. Full privacy policy: https://ytubviral.com/privacy ────────── FREQUENTLY ASKED QUESTIONS ────────── Do I need a ytubviral.com account? No — you get the full SEO scorecard on any video or Short, and velocity badges on every thumbnail, without one. An account (free, 30 seconds) unlocks keyword research, comment sentiment, your channel dashboard, and 10 AI generations a month. Competitor analysis and A/B testing are Pro. If you signed up with Google, the extension connects automatically when you visit ytubviral.com. Does it work on YouTube Shorts? Yes — the panel works exactly the same on Shorts as on regular videos. Does this work on Firefox? Not yet — Chrome and Chromium-based browsers only (Chrome, Brave, Edge, Opera) for now. Will it slow down YouTube? No. The panel only loads content when you open it, API calls only happen when you navigate to a supported page type, and velocity badges load lazily as thumbnails scroll into view. Is the keyword data real? Yes. Stats are calculated using live data from the YouTube Data API v3 and cached for 24 hours. Scores (SEO Score, Opportunity Score) are YTubViral's own metrics, not official YouTube data. Can I use it on channels that aren't mine? Yes — that's the main use case. You can analyze any public YouTube channel. Does it work in YouTube Studio? Yes. SEO Score badges appear on your video list, a live SEO panel sits next to the title in both the editor and the upload dialog with a best-time-to-post hint, and the AI can suggest tags and generate descriptions. Pro users can also launch a real A/B title test directly from the editor. ────────── SUPPORT ────────── Website: https://ytubviral.com Email: hello@ytubviral.com We read every support email and typically reply within 24 hours.
