AiViralCut

AiViralCut is a browser-based AI video editor for making short-form clips for TikTok, Instagram Reels, and YouTube Shorts, built as a privacy-focused alternative to CapCut. All editing and AI run locally: it uses 100% in-browser WebGPU processing with 60 FPS exports and no watermarks, so footage never leaves the machine. On-device Whisper transcription captions a 10-minute video in seconds without a cloud upload, and the editor adds per-word text effects (word punch, dual gradient, stroke, glow), real-time 3D LUT color grading, and ripple transitions placeable at any timestamp across four tracks. Safe-zone collision detection covers nine vertical and horizontal aspect ratios including 9:16, 1:1, 16:9, and 4:5, so captions and effects stay inside each platform's crop. The Community Edition is free forever with unlimited editing and 25 daily AI credits; Creator Pro is $12/month and Lifetime Pass is $99 one-time. The audience is short-form creators who want fast, private editing without a recurring subscription or cloud dependency. For BestAIFor readers weighing AI video editor tools, AiViralCut stands out by keeping processing on-device rather than in the cloud.

Editing and captioning short-form viral videos for TikTok, Reels, and Shorts locally in the browser with text effects, color grading, and transitions.
