2026 OnceTool — Peek YouTube Like Count

OnceTool — Real YouTube Like Counts on Hover Stop clicking on bad videos. Hover any YouTube thumbnail for 0.25 seconds — a small icon appears in the corner. Click it and you'll see the real like count, before you commit to watching. Why we built this "Clicked a clickbait title, wasted 10 minutes" — it happens every day. Like count is the most direct quality signal on YouTube, but YouTube hides it behind the click. This extension surfaces it the moment you're deciding — one more data point, ten fewer wasted minutes. Get started in three steps 1. Add to Chrome → pin it to the toolbar (puzzle button → pin icon) 2. Sign in with OnceAccount (first hover prompts login; or buy a license key anonymously) 3. Open YouTube and pause on any thumbnail for 0.25 seconds What you'll see - Real like counts, sourced from Google's official YouTube Data API v3 - Works on home, search, channel pages, Shorts — anywhere thumbnails appear - 30 ms response for the second person to query a video (7-day server cache) - 0.25-second delay avoids accidental triggers; configurable to 150 / 300 / 500 / 800 ms - Stays out of your way: the icon only appears on hover and disappears on mouse-out Data source & what we don't do Source: Google's YouTube Data API v3 (official authorization) - We don't scrape YouTube pages - We don't call YouTube's private APIs - The numbers come straight from YouTube — same as what you'd see after clicking What we don't do: - We don't track which videos you browse - We don't sell your hover behavior to anyone - Each hover sends only the video ID to our backend, which returns the like count - Your OnceAccount session lives in chrome.storage.local — never leaked to other sites Pricing Credits-based, no monthly fee. - 10 free hovers per day (buy credits when you need more) - Three packs: - Basic: US$4.99 → 1,500 credits - Value: US$9.99 → 3,500 credits (best deal, +17% credits per dollar) - Pro: US$19.99 → 8,000 credits - One-time purchase.
