OpusClip virality score vs. ViralGrader: which do you need?
They do different jobs. OpusClip is an AI clipping tool: it cuts a long video, such as a podcast or stream, into short clips and gives each one a Virality Score from 0 to 99 to help you pick which to post, on its Starter and Pro plans. ViralGrader grades a short you've already made, for the app you're posting it to, and tells you exactly what to change. If you start from long videos, use OpusClip to find clips. If you film shorts yourself, use ViralGrader to check and fix them before you post.

- You want a tool to find the best moments for you and rank them.
- You need clipping, captions and reframing in one place.
When ViralGrader is the better pick
- You film or edit shorts yourself and want to know if this cut is ready to post.
- You want exact edits, with the second and frame, not just a ranking.
- You want your on-screen text checked against Reels, TikTok and Shorts buttons and captions.
- You want a score without a subscription: your first scan is free, score included.
Why the two scores differ
OpusClip's score compares clips cut from the same long video, so you can choose between them. ViralGrader's viral score rates one finished video against what short-form viewers reward on the app you pick. A clip can rank first among its siblings and still have a slow first second or text hidden under a button.
Using both
They fit together. Cut clips from a long video in OpusClip, polish the one you'll post, then upload that file to ViralGrader with Reels, Shorts or TikTok selected to check the opening, the pacing and where your text sits before it goes live.
What neither tool can do
Neither tool can promise views. Both predict how well a video is likely to hold attention from the video alone, while timing, topic, your audience and luck still play a part. Treat any score as a guide to what to fix, not a forecast.
