Built a Full-Featured AI Video Suite
Building a Full-Featured AI Video Suite in Hours (Not Weeks) — Here's How
I've been curious about what Google Antigravity could actually handle — not just toy projects, but something useful. Something I'd actually want to use daily.
Enter ClipGenerator.ai — an AI-powered video suite with 9 features built entirely through vibe coding:
- 🎵 Music Visualizer
- ✂️ Viral Clip Generator
- 🔊 Audio Extractor
- ✂️ Video Trimmer
- ⏱️ Speed Adjustment
- 📝 YouTube Script Summarizer
- 🖼️ AI Image Generation
- And a few more I haven't even launched yet
The wild part? I didn't write this the traditional way. No weeks of planning, no ticket backlog, no endless debugging sessions. I described what I wanted, Antigravity built it, and I iterated from there.
That's the power of vibe coding + OpenClaw. You're not just automating tasks — you're architecting solutions with natural language. The AI handles the implementation; you handle the vision.
The takeaway for this community:
- Tools like Antigravity aren't gimmicks — they're production-ready
- The bottleneck isn't AI capability anymore, it's knowing what to build
- OpenClaw users have a massive advantage: we already think in workflows

Would love to hear what you'd build with this approach.
Technical Prompt, Ideal for Implementation in OpenClaw Gateway or Antigravity:
AI Video Suite - Full Technical Specification
Project Overview
Build a comprehensive AI-powered video editing suite as a web application. The app should be intuitive enough for creators without video editing experience, yet powerful enough to streamline common workflows. Target users: content creators, social media managers, YouTubers, and marketers.
Tech Stack
- Frontend: React + Vite, TailwindCSS for styling
- Backend: Node.js with Express (or serverless functions)
- Database: Supabase or Firebase for user storage
- Video Processing: FFmpeg (server-side), Canvas API for client-side previews
- AI Services: OpenAI API (GPT-4 for summarization), Replicate API (for image generation), custom ML models for video analysis
- Storage: AWS S3 or Cloudflare R2 for video uploads
Core Features
1. Music Visualizer
Function: Generate animated visualizations synced to audio tracks
Technical Requirements:
- Accept audio file upload (MP3, WAV, OGG) or extract audio from video
- Analyze audio frequency data using Web Audio API (AnalyserNode)
- Render canvas-based animations that respond to:Beat detection (BPM analysis)Frequency bands (bass, mid, treble)Volume amplitude
- Animation styles:Waveform bars (vertical, radial)Particle systemsCircular spectrum analyzerNeon glow effects
- Output: MP4 video at 1080p or 4K
- Customizable: colors, bar count, sensitivity, animation speed
2. AI Video Clipper (Viral Clip Generator)
Function: Automatically identify key moments in long-form video and create short clips
Technical Requirements:
- Accept video upload (MP4, MOV, WebM) up to 2GB
- Process video to extract:Audio transcription (using Whisper API)Visual change detection (scene cuts, camera switches)Audio energy analysis (sudden volume changes, spikes)Face detection for speaker presence
- Algorithm to score "highlight potential":Moments with high audio energyScene cuts with speechDuration: auto-detect optimal clip length (15-60 seconds)
- Auto-generate subtitles:Burned into video using FFmpegStyle: bottom third, customizable font/size/colorSupport for keyword highlighting
- Output: Multiple MP4 clips with vertical (9:16) and square (1:1) aspect ratios
- Batch processing: generate 5-10 clips automatically
3. Video Trimmer
Function: Simple start/end point trimming with preview
Technical Requirements:
- Drag-and-drop video upload
- Visual timeline with frame thumbnails
- Set start and end points via:Timecode inputDraggable handles on waveform/timeline
- Live preview before export
- Output: MP4 with same quality as input
- Preserve audio sync
4. Video Speed Adjustment
Function: Change video playback speed
Technical Requirements:
- Preset speeds: 0.25x, 0.5x, 0.75x, 1x, 1.25x, 1.5x, 2x
- Custom speed input (0.1x - 4x)
- Maintain audio pitch option (time-stretching)
- Apply to: entire video or selected segment
- Preview in browser before export
5. Audio Detacher (Audio Extractor)
Function: Extract audio track from video
Technical Requirements:
- Accept any video format with audio track
- Extract and export as MP3 (320kbps), WAV, or OGG
- Option to remove original video audio when using other tools
- Waveform visualization during processing
6. AI Image Generator
Function: Generate images from text prompts
Technical Requirements:
- Text input for detailed prompts
- Negative prompts support
- Model selection (Stable Diffusion, DALL-E 3)
- Aspect ratio presets: 16:9, 9:16, 1:1, 4:3
- Style presets: photorealistic, cartoon, anime, abstract
- Image-to-image (upload reference image)
- Output: PNG or JPEG
- History of generated images
7. YouTube Script Summarizer
Function: Extract and summarize content from YouTube videos
Technical Requirements:
- Accept YouTube URL input
- Process video to extract:Full transcript (YouTube API or Whisper)ThumbnailTitle and description
- Generate:TL;DR summary (3-5 sentences)Key timestamps with topic labelsActionable takeawaysSuggested viral clip timestamps (based on engagement markers)
- Export as: text, markdown, or PDF
- Option to send clips to viral clipper
UI/UX Requirements
Layout
- Dashboard: Grid of tool cards with icons and descriptions
- Workspace: Each tool gets dedicated page with:File upload zone (drag-and-drop)Preview areaControls sidebarExport options
Design System
- Dark mode default (creator-friendly)
- Accent color: #6366f1 (indigo)
- Clean, minimal interface with clear affordances
- Progress indicators for all processing tasks
- Toast notifications for completion
User Flow
- Land on dashboard → select tool
- Upload file or paste URL
- Configure options
- Process (show progress)
- Preview result
- Download or continue to next tool
Additional Features

Example Prompt to Start With
"Build an AI video suite with a dashboard landing page. Include 7 tools: music visualizer (accepts audio, generates waveform animations), viral clipper (accepts video, finds highlights using audio energy analysis, auto-generates subtitles), video trimmer (timeline UI with handles), speed adjuster (presets + custom), audio extractor (video to MP3), AI image generator (text-to-image with Stable Diffusion), and YouTube summarizer (URL input, extracts transcript, generates summary and key timestamps). Use React + Tailwind, dark theme, indigo accents. Each tool page has upload zone, preview area, and export options."
