The tool uses GPU OCR and can be integrated with AI models to categorize ad angles, offering a low-cost alternative to commercial ad spy platforms. The developer also provides a free web demo on Hugging Face Spaces and a RapidAPI marketplace listing.", "body_md": "In performance marketing and e-commerce, the first 3 seconds of a video ad (the \"Hook\") determines 80% of its return on ad spend.\n\nIf you analyze winning TikTok and Instagram Reels ads, you'll find that most top-performing ads don't rely on voiceover alone: **they burn bold, dynamic text overlays directly onto the video screen.**\n\nCommercial ad spy platforms (like Foreplay or PiPiADS) charge anywhere from $99 to $299/month for access to their creative databases.\n\nIn this tutorial, we will build an automated **TikTok Ad Hook Extractor** in Python in under 20 lines of code.\n\n```\nTikTok / Reels Ad URL\n        │\n        ▼\n[Video OCR Ripper Engine] ──► (Skips static frames, runs GPU OCR)\n        │\n        ▼\nExtracted Hook Text (First 3s) + Discount Codes + Full .SRT Transcript\n        │\n        ▼\n[OpenAI / Claude] ──► Categorizes the Angle (Problem/Solution, Curiosity, Social Proof)\n        │\n        ▼\nNotion Database / Airtable (Ready for Creative Team)\n```\n\nWe'll use `tiktok-subtitle-ripper`, a lightweight open-source library that extracts on-screen text overlays and subtitle files directly from video links:\n\n```\npip install tiktok-subtitle-ripper\n```\n\nHere is the complete script to extract the visual hook and full transcript from any competitor ad:\n\n``` python\nimport httpx\n\nRAPID_API_KEY = \"YOUR_API_KEY\"\nAPI_URL = \"https://tiktok-reels-subtitle-video-ocr-ripper.p.rapidapi.com\"\n\nheaders = {\n    \"X-RapidAPI-Key\": RAPID_API_KEY,\n    \"X-RapidAPI-Host\": \"tiktok-reels-subtitle-video-ocr-ripper.p.rapidapi.com\"\n}\n\ndef analyze_ad_creative(video_url: str):\n    # 1.
