Curlo

Curlo is an AI-powered, privacy-first audio asset manager built exclusively for macOS. Powered by fully local AI models running directly on your Mac, Curlo helps sound designers, film & video editors, short drama creators, and audio post-production professionals organize, search, preview, and manage massive sound effect and music libraries without relying on cloud services. Unlike traditional asset managers that depend on filenames and manual tagging, Curlo understands the actual sound content of your audio files. Using AI-powered Semantic Search, you can find sounds naturally by describing what you want to hear, including: • “heavy rain on a tin roof” • “footsteps on gravel” • “gentle piano melody” Optimized natively for Apple Silicon, Curlo delivers a lightning-fast, high-density workflow even when managing tens of thousands of files—all while keeping your data and search queries 100% private and on-device. -------------------------- KEY FEATURES: • Semantic & Metadata Search Search using natural language, or use powerful slash commands (like /filename, /tag, /ucs, or /format) for precise metadata filtering. • Fluid DAW Integration & Clip Extraction Preview audio in a smooth, zoomable waveform interface. Highlight exactly the clip you need, then drag it directly into Pro Tools, Logic Pro, Reaper, Premiere Pro, and more. You can also bounce clips instantly to local folders or custom collections. • Similar Audio Discovery Select any audio file or just a specific waveform region, instantly find other sounds in your library with a similar sonic character. • AI Auto-Tagging & UCS Support Organize your library using custom tags or the industry-standard Universal Category System (UCS). Curlo can automatically infer and batch-assign UCS categories and tags for uncategorized files based on their metadata and acoustic signature. • Professional Metadata Editing Read, write, and edit metadata directly inside your audio files, including Artist, Album, Genre, Grouping, and detailed UCS fields. • Flexible Collections Group sounds into virtual Collections without altering your hard drive's folder structure. • Deep Filtering & Sorting Refine any search by Duration, Format, Sample Rate, Bit Depth, Channel Count, and more. • Local Developer API Integrate Curlo directly into your studio’s custom automation pipelines or scripts via the built-in localhost HTTP API. • Broad Format Support Supports all major professional audio formats, including WAV, AIFF, FLAC, MP3, CAF, RF64, OGG, OPUS, and more. -------------------------- SYSTEM REQUIREMENTS: • Mac with Apple Silicon (M series chips) • macOS 14.6 or later
