Who is OpusClip for, and who is MakeViral for?
OpusClip is a clipper. You hand it a long video, by upload or by link from ten or more sources, and it finds the moments, reframes them to vertical, tracks the subject, adds animated captions and gives you clips. Its own homepage says ClipAnything "turns any genre, vlogs, gaming, sports, interviews, explainer videos, into viral clips in 1 click." Everything in the product assumes footage exists.
MakeViral starts one step earlier. There is no upload. You give it a prompt, a written script or a product URL, and it returns a 9:16 video with an AI script, an AI voiceover, word-timed captions and a background. The eight formats are specific posts, not generic templates: Reddit story, fake text message over gameplay, full-screen iMessage typing, Would You Rather, quiz, fade-in meme, 4-photo reveal and an AI voiceover talking head.
That makes the choice mechanical rather than a matter of taste:
- You record long video already. Buy OpusClip. MakeViral cannot use your footage at all.
- You have an idea and no camera. Buy MakeViral. OpusClip has nothing to clip.
- You do both. Run both. They do not overlap, and OpusClip's Free plan costs nothing to keep open.
The common mistake is buying a clipper to start a faceless channel. A clipper multiplies footage you already made. If you have not made any, it multiplies zero.
