Frequently asked
How does ViralMint compare to Opus Clip on pricing?
ViralMint has an open-source tier with a small daily allowance that covers light AI use, plus local features like Pexels stock-footage video assembly, Edge TTS voice (400+ voices) and word-by-word ASS captions. Heavier AI generation is pay-as-you-go via prepaid USD top-ups, no subscription.
Can ViralMint auto-clip long videos like Opus Clip?
Yes. ViralMint's Clip Studio uses Whisper to transcribe a long video and an AI viral-clip picker to identify the highest-potential 30–60 second moments, then exports each as 9:16 with captions burned in. The AI scoring model is different from Opus Clip's, so head-to-head clip quality varies by source content.
Does ViralMint auto-publish to YouTube and TikTok the way Opus Clip does?
No, and that's a deliberate trade-off versus Opus Clip. Opus Clip auto-publishes; ViralMint hands you a finished mp4 plus AI-drafted YouTube and TikTok titles, descriptions and tags to copy-paste when posting. Auto-upload was prototyped here and intentionally removed because it kept breaking on platform OAuth and cookie changes. If hands-free posting is your top priority, Opus Clip wins on that single capability — for trend scouting, AI script writing, Smart Video assembly and the modular Tools page, ViralMint is the broader pipeline.
Is there an open-source Opus Clip alternative?
ViralMint is the closest open-source equivalent. Source is on GitHub at github.com/openclaw-easy/ViralMint under AGPL-3.0, so you can audit the viral-clip scoring model, fork it, or run it from source. Opus Clip itself (at opus.pro) is closed-source SaaS — the auto-clip scoring is a black box. Other open-source clippers exist as command-line scripts, but ViralMint is the only one shipping a real desktop UI with Whisper-based viral-moment detection, word-by-word ASS captions and multi-aspect export in the same package.
What's the difference between OpusClip, Opus Clip and Opus.pro?
They're all the same product. The company brands itself as Opus Clip (two words, the official form), but it's commonly written as OpusClip (one word), OpusClips (plural) and Opus.pro (the domain the app runs on at opus.pro). You'll also see it called Opus AI in some contexts. All five forms refer to the same SaaS clipper. ViralMint is a free, open-source alternative to it — the comparison on this page applies regardless of which spelling you searched for.
Where do I log in to Opus Clip — or sign up for OpusClip free?
If you're looking for Opus Clip's login page, head to opus.pro and use the Log In button in the top navigation — the app is hosted on a subdomain of opus.pro and the marketing site will route you to the right place. If you ended up here searching for OpusClip login, OpusClip sign in or an OpusClip free tier and you'd rather try a no-subscription alternative first, ViralMint is a free download for macOS, Windows and Linux with the same auto-clip flow (Whisper transcription + AI viral-clip picker + word-by-word captions), no monthly fee, and a daily starter allowance that covers light use. Create your account in 30 seconds at viralmint.net/app without a card, then download the app to start clipping.
