Curlo

About Curlo

Curlo is a privacy-first macOS app for searching, previewing, and organizing large local sound libraries. It lets you describe the sound you want in natural language and returns matching SFX or music, while keeping all audio and queries on-device.

Review

Curlo focuses on making it easy to find sounds inside large local collections by using semantic search and local analysis. The app builds an index on import, supports metadata editing and tagging, and offers integrations that streamline moving clips into common audio and video tools.

Key Features

• Semantic search for local audio files using natural language (offline processing).
• Metadata commands and editing, including tag and format searches.
• Similar-audio search from a file or a selected region to find matching clips.
• Drag-and-drop export to DAWs and video editors, plus a local API for custom workflows.
• AI-assisted auto-tagging and support for category/standardized metadata fields.

Pricing and Value

There is a free option available; detailed pricing tiers and limits are not listed on the product summary and should be checked on the official site. The main value proposition is saving time when hunting for specific sounds in a large, local library while preserving on-device privacy, which is especially useful for professionals who keep assets offline.

Pros

• Keeps audio files and search queries entirely on the Mac, which is good for privacy-sensitive workflows.
• Natural language search makes it faster to find sounds when filenames or tags are incomplete.
• Works with common audio/video workflows through drag-and-drop and a localhost API.
• Scales to reasonably large libraries without rebuilding the entire index after changes.
• Offers metadata editing and automated tagging to improve long-term library organization.

Cons

• macOS-only at launch, so it isn't available to users on other platforms.
• New release status means some niche or edge-case sounds may require refinement and more testing.
• Indexing and on-device models may use noticeable CPU or disk during initial import on very large collections.

Curlo is best suited for sound designers, editors, and producers who manage large local audio collections and prefer an offline, privacy-aware workflow. It's a practical tool for anyone who frequently struggles to find the right clip by filename or existing tags and wants tighter integration with their editing tools.
