ViralMint
ViralMint is an open-source desktop application (macOS, Windows, Linux) that provides a complete pipeline for short-form video creation. It scouts trending content from platforms like YouTube, TikTok, Douyin, Reddit, and Google Trends, scoring videos on virality and channel-outlier breakouts. Built-in download support via yt-dlp covers over 1,800 video sources. Local Whisper transcription and AI analysis extract hooks, structure, and tone from top-performing clips. For original video generation, ViralMint offers multiple modes: an AI-scripted pipeline with stock footage, voiceover (Gemini 3.1 Flash TTS, free Edge TTS, or on-device cloned voices), word-by-word captions, and automatic background music; direct AI video generation using models like Sora 2 Pro, Veo 3.1, and Wan; motion-graphics animations rendered from HTML; and automatic promo video creation from any website URL. All outputs are watermark-free. The application operates without mandatory subscriptions, providing a small daily starter allowance for pay-as-you-go AI features. It also includes a 58-tool MCP server, enabling integration with Claude, Cursor, and other MCP clients to drive the entire pipeline via plain-language commands. Released under the AGPL-3.0 license, the tool emphasizes local processing and user control, requiring no API keys to get started.
