DOCUMENTATION
Everything you need to turn long-form video into a week of content.
KlipFast is an AI-powered video repurposing tool. Upload a long-form video once and get AI-generated short clips, captions, and 10 types of social content — automatically.
KlipFast accepts most common video formats. Drag and drop your file onto the upload area or click to browse.
Choose a quality tier that matches your deadline and output requirements.
Captions are burned into your clips. Choose a style before processing.
KlipFast analyzes your entire video and scores each segment for viral potential based on speech energy, sentence completeness, topic density, and emotional peaks.
Format: All clips are exported as 9:16 vertical (1080×1920) — optimized for Reels, TikTok, and YouTube Shorts.
Length: 30–90 seconds per clip. The AI targets the sweet spot for each platform.
Virality score: Each clip gets a score from 0–100. Higher scores indicate stronger hooks, complete thoughts, and high information density.
Speaker crop: With speaker diarization enabled, the crop intelligently follows the active speaker.
Every processed video generates 10 types of written content, ready to copy and publish.
Source videos are deleted immediately after processing and do not count toward storage. Clips are stored securely on Cloudflare R2.
The KlipFast API lets you integrate video processing into your own products. Available on Starter plan and above.
