One App. Every Clipping Workflow.
From a pasted link to an exported short — every step runs on your machine.
Paste a Link. Start Clipping.
Paste any YouTube URL and ClipSonic downloads and transcribes it automatically — no separate downloader, no manual steps.
- YouTube URLs, auto-downloaded
- Live progress with cancel support
- Pick a quality tier (up to 1080p)
- Auto mono 16kHz audio extraction
Drop Any Video. No Uploads.
Have the file already? Drag it in. ClipSonic reads duration, resolution, and a thumbnail instantly, then transcribes locally — the file never leaves your computer.
- MP4, MOV, MKV, and more
- Instant duration/resolution/thumbnail
- No file ever leaves your machine
- No size or duration limits
AI Picks the Best Moments.
Groq, OpenAI, or a local model on your own machine reads the full transcript and returns ranked clip suggestions — each with a title, a hook reason, and a viral score, so you know why a moment was picked before you even watch it.
- Hook reason + viral score per clip
- Cloud or fully-local AI — your choice
- Handles hour-long videos via chunking
- Approve, refine, or reject each one
Or Skip AI. Auto-Split by Length.
Manual mode slices the whole video into fixed-length clips — no AI, no API key. Cuts snap to the nearest natural silence so you never land mid-word.
- 30 / 45 / 60 / 90 / 120s presets
- Cuts snapped to silence
- Full-coverage, non-overlapping clips
- Captions still optional, on request
A Closer Look at What You Get
The tools that turn a raw upload into a finished, watchable short.
Know Exactly Which Moments Will Hit.
ClipSonic doesn't just guess timestamps — it reads the transcript and scores each candidate moment for hooks, punchlines, and complete thoughts, returning a viral score and a plain-English reason for every suggestion. Run the model in the cloud (Groq or OpenAI) or fully on-device with a local model via Ollama. Long videos are chunked and de-duplicated automatically, so a 60-minute recording still gets sensible coverage from start to finish.
- Title, hook reason & viral score per clip
- 5–15 ranked suggestions per video
- Cloud or local model — no lock-in
- Approve, refine, or reject before rendering
Every Clip, Perfectly Framed.
A plain center-crop always works as a baseline, but ClipSonic can also detect and follow faces frame-by-frame — smoothed so the camera never jitters — to keep a speaker centered in 9:16. Two guests? Use the split-screen layout that tracks each person independently. Gaming or reaction content? Stack a tracked facecam over a looping background clip.
- Single-speaker face tracking
- Two-person split-screen (each tracked independently)
- Gameplay + facecam split layout
- Plain center-crop or original aspect ratio always available
Captions That Actually Get Watched.
Six built-in styles — Clean, Karaoke, Bold Pop, Neon Glow, Bounce, Boxed — each with word-by-word highlight animation as the audio plays. Preview live over the clip, drag the caption to any position on the frame, and the chosen style is saved per-clip, not app-wide.
- 6 distinct animated presets
- Word-by-word highlight as it's spoken
- Drag-to-position, saved per clip
- Live preview before you render
From Approved Clip to Finished Short — One Pass.
Cutting, reframing, and captions render together in a single ffmpeg pass instead of three separate re-encodes, keeping quality high and export times low. Export one clip or hit "Export all" to batch-render every approved clip with live per-clip progress.
- Cut + reframe + captions in one render
- Batch-export every approved clip
- Quality tiers up to 1080p
- Custom output folder, non-colliding filenames
Your Choice: Fast Cloud AI, or Fully Offline.
Every AI step can run in the cloud or right on your own machine. Transcribe with local Whisper (GPU-accelerated whisper.cpp, with the word-level timing the captions need) and detect highlights with a local model via Ollama — no API key, no per-minute fees, no internet required. Nothing, not even the transcript text, ever leaves your computer. Prefer the fastest setup? Point transcription and highlights at Groq or OpenAI instead. Mix and match per feature — it's a setting, not a lock-in.
- Local Whisper transcription — download a model once, run offline
- Local highlight detection via Ollama — no key, on-device
- Or use Groq / OpenAI — pick a provider per feature
- GPU-accelerated where available, CPU fallback everywhere

Common Questions
How does ClipSonic find the best clips?
It transcribes your video, then an AI model reads the transcript and scores moments for hooks, punchlines, and complete thoughts — each suggestion comes with a viral score and a plain-English reason. Run that model in the cloud (Groq or OpenAI) or entirely on your own machine (a local model via Ollama) — your choice.
Can I run ClipSonic completely offline?
Yes. Choose local Whisper for transcription and a local model via Ollama for highlight detection, and the entire pipeline — transcribe, find clips, frame, caption, export — runs on your own machine with no API key and no internet at all. Nothing, not even the transcript text, ever leaves your computer.
Does ClipSonic upload my video anywhere?
No. Cutting, face-tracking, captioning, and exporting always happen locally on your machine. If you pick a cloud AI provider, only the transcript text is sent to find highlights — never the video file. Pick the local models instead and even that stays on your device.
Can I make clips without AI?
Yes — Manual mode auto-splits any video into fixed-length clips (30/45/60/90/120s), snapped to natural silence so cuts don't land mid-word. No AI or API key required.
Does it track faces automatically?
Yes. ClipSonic detects and follows faces frame-by-frame to keep the speaker centered in a 9:16 crop, including a two-person split-screen and a gameplay-plus-facecam layout.
What do the animated captions look like?
Six presets — Clean, Karaoke, Bold Pop, Neon Glow, Bounce, Boxed — each with word-by-word highlight animation, and you can drag the caption to any position on the frame.
Is this a one-time payment?
Yes. Pay once and own it forever — no monthly subscription, no per-clip fees, no watermark.
Which AI providers are supported?
For transcription: Groq, OpenAI, or local Whisper running on your own machine (GPU-accelerated, no key). For highlight detection: Groq, OpenAI, or a local model via Ollama. Pick a provider per feature in Settings — mix cloud and local however you like.
What is local Whisper transcription?
A speech-to-text engine (whisper.cpp) that runs directly on your computer — GPU-accelerated on most machines — with word-level timing for the animated captions. Download a model once and transcribe unlimited audio offline, with no API key and no per-minute cloud fees. Great for long podcasts and anything you want kept private.
What video sources can I use?
Paste any YouTube URL or drop a local video file (MP4, MOV, MKV, and more). YouTube downloads run automatically in the background.
Do I need a powerful computer?
Any modern Windows or Mac machine. Rendering runs locally via ffmpeg — no cloud render queue, no waiting in line. Local AI transcription is fastest with a GPU; on a CPU-only machine it still works, just slower — or use a cloud provider instead.
Stop Paying Monthly to Clip Your Videos.
AI highlight detection, face tracking, animated captions, batch export — one payment, forever.
