Stories, not soundbites
Viral Clipper transcribes the recording, works out who is speaking and picks complete moments: the question with its answer, the story with its punchline.
Free beta
Viral Clipper
A free AI clip maker for Mac. Drop in a stream, podcast, interview or audio file and Viral Clipper finds the clips worth posting, with the AI running on your Mac instead of a cloud service.
- Clips are ranked strongest first and appear as soon as each one is ready.
- Clips are cut to keep the setup with the payoff, so they make sense on their own.
- Trim from the transcript, pick a caption style and export for TikTok, Reels, Shorts, X or YouTube.
Made for long recordings
Hours of footage is the point, not a problem. Viral Clipper reads the whole recording, so the best moment can be quiet, late or off topic and still make the list.
Start posting before it finishes
Clips are ranked across everything you dropped in. Watch and export the first ones while the rest are still being found.
No uploads, no quota
Transcription, speaker identification, clip finding and rendering all run on your Mac. There is no account, no subscription and no per-minute limit.
A free OpusClip alternative that runs on your Mac
Cloud clip makers such as OpusClip (Opus Clip) work on their servers: you upload the recording, and a plan decides how many minutes you can process each month. Viral Clipper does the same job on your own Mac, so none of that applies.
No plan, no credits
There is no subscription, no credit balance and no monthly minutes. Process a three-hour stream every day if you like.
Nothing to upload
Recordings stay on your Mac, so there is no upload wait, no file-size limit and no account to create.
No watermark
Exports carry your captions and nothing else, in the shape each platform wants.
The trade-off is hardware: a cloud service runs in any browser, while Viral Clipper needs an Apple-silicon Mac (what you need). Viral Clipper is not affiliated with OpusClip.
How it works
-
1
Drop in a recording
Video or audio, minutes or hours long. Drop several files and they become one session, so clips are compared across all of them.
-
2
Watch the clips arrive
Each clip appears in the list with its title and transcript as soon as it is ready, strongest at the top.
-
3
Make it yours
Start or end a clip on any transcript line, or drag the timeline. Pick a caption style and fix any word.
-
4
Export and post
Export one clip, or every clip into a folder with its own trim and captions, shaped for where it is going.
Export for where you post
Pick a destination and Viral Clipper sets the shape, framing and captions, and warns you when a clip runs past that platform’s length limit.
Vertical, framed on faces
1080×1920 with the crop placed on the people in the shot, splitting the frame top and bottom when two people share it. Audio-only recordings become a captioned vertical video.
Seven caption styles
Burned-in, word-timed captions in styles from clean to loud, previewed live on the clip. Fix any word before you export.
Every other shape
A square face-framed crop for X, the original shape with a subtitle file for YouTube, or a timeline for Final Cut Pro, DaVinci Resolve or Premiere Pro.
What you need
Viral Clipper runs its AI on your own Mac instead of a server, so it asks a little more of the Mac than a typical app.
Apple silicon, macOS 15
Any Mac with an M-series chip running macOS 15 Sequoia or later.
32 GB, or an OpenRouter key
With 32 GB of memory everything runs on your Mac. With less, you can find clips using your own OpenRouter key instead.
30 GB free to start
The AI models download once on first launch, about 20 GB, and resume if interrupted. The rest is working room for your recordings.
Frequently asked
Does anything leave my Mac?
Not your recordings. Everything runs on your Mac. Viral Clipper goes online to download its AI models on first launch and to check for app updates, which it asks about before the first check.
Is Viral Clipper a free alternative to OpusClip?
Yes. It does the same core job, finding the strongest moments in a long video and exporting them as captioned vertical clips, and it is free with no credits, minutes cap or watermark. The difference is where the work happens: OpusClip is a cloud service you upload to, and Viral Clipper is a Mac app that runs the AI on your own machine.
My Mac has less than 32 GB of memory. Can I still use it?
Yes, with your own OpenRouter API key. In that mode the transcript text of your recordings (never the audio or video) is sent to OpenRouter to find and order clips, billed to your OpenRouter account. Speech recognition, speaker identification and rendering still run on your Mac. You can switch modes in Settings.
Are the clips ready to post?
Many are, as they come out. This is a beta, though: some clips start a line too late or end a little early, so watch each one before posting. Moving a start or end to another transcript line takes a click.
How long does a recording take?
It depends on the recording’s length and your Mac. The first clips appear while the rest of the recording is still being read, and you can leave a session and come back: progress stays in the Library.
How do updates work?
Choose Check for Updates… in the Viral Clipper menu, or let the app check automatically. Updates are signed and install with one click.
