FAQs
The practical details behind Curlo's local AI search, privacy model, and sound library workflow.
Which languages can I use for AI search?
Curlo supports almost all major languages for semantic search. Search quality may vary by language and query, and semantic search is free to use, so you can download Curlo and try it with your own language and library.
Does Curlo upload my audio files or require the internet?
No. Curlo indexes your library and runs AI search locally on your Mac. Your audio files, metadata, indexes, and search queries stay on your device, and no network connection is required for indexing or search.
Is Curlo safe?
Yes. Curlo only needs network access to check subscriptions and updates. Everything else can run without a network connection, and all other content is processed locally on your Mac.
How do I manage or cancel my subscription?
You can manage or cancel your subscription in Curlo under Settings > Pro. You can also visit the Creem Customer Portal, or contact [email protected] for help.
I already subscribed to or purchased Curlo in the Mac App Store. Do I need to buy it again?
If your Mac App Store subscription or purchase has not ended, please contact us at [email protected] with your purchase record or invoice, and we will help migrate your Pro subscription.
What is semantic search?
Semantic search lets you describe the sound you want in natural language, such as heavy rain, sci-fi laser, or gentle piano. Curlo searches by meaning instead of relying only on exact filenames or tags.
How large of a sound library can Curlo handle?
Curlo is designed for large local libraries and can still run smoothly with a library of 100,000 audio files.
What kind of sound libraries is Curlo for?
Curlo is built for local sound effects, samples, music cues, and mixed audio libraries used by sound designers, editors, musicians, and creators on Mac.
How is Curlo different from cloud sound libraries?
Cloud libraries help you discover or download sounds online. Curlo focuses on the audio files you already have on your Mac, with private local AI search, metadata, tags, UCS classification, and DAW handoff.
