Clumi vs Curlo

Clumi and Curlo are both audio & voice tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Clumi

Upload a file, wait a few minutes, download the separated stems. That is the entire workflow. No software install, no configuration, no account required for the initial free processing quota. The tool handles vocal removal, individual stem isolation (drums, bass, piano, guitar), and noise cleanup in the same interface. The ceiling appears fast: the free tier caps at three files, file duration tops out at 10 minutes, and file size is capped at 100 MB. Teams running batch processing or working with long-form audio hit that wall on the first session and move to a paid tier or a different architecture entirely.

Curlo

Curlo is a macOS audio search and organization tool that lets sound designers and editors query their local libraries the way they'd describe a sound to a colleague. The core workflow is semantic search: you describe what you need, and Curlo surfaces matching files from your collection. Processing runs locally, which means your proprietary sound library never leaves the machine. The local API extends this into DAW and production pipelines, so search can live inside the tools you already use. The ceiling appears around complex cross-library deduplication and anything requiring Windows or cloud-sync workflows — those teams look elsewhere.

Pros	No account required for initial processing, so you get a separated track in minutes without handing over an email address or setting up credentials. Runs entirely in the browser across desktop, tablet, and mobile, which means there is no software to install and no local GPU or processing power required — useful when you are on a machine you do not control. Covers individual stem isolation beyond just vocals — drums, bass, piano, guitar each get their own extractor — so a producer testing whether a specific instrument can be cleanly removed does not need a second tool. Noise removal utilities (echo, reverb, breath, crowd, wind, static) live in the same interface as stem splitting, so cleaning a recorded track before separation does not require switching tools. Audio utilities like key/BPM detection, pitch shifting, and audio cutting are bundled, which means a karaoke creator can identify a song's key and trim the track in the same session.	Semantic description-based search, so you find a 'wet gravel footstep' by describing it rather than scanning hundreds of ambiguously named files — the forty-minute browse becomes a query. On-device processing with no audio data sent to external servers, which means studios with proprietary or NDA-covered assets can use it without a legal review of data handling policies. UCS-standard metadata writing that embeds classification directly into files, so your organization survives a migration away from Curlo rather than dying in a proprietary database. Local API on paid tiers, so audio search can be triggered from inside a DAW or a production script instead of requiring a context switch to a separate app. Free tier handles libraries up to 5,000 files, which means a solo editor or junior sound designer can validate the workflow before committing to a paid tier.
Cons	The free quota caps at three files with no reset mechanism described in the page content — a producer evaluating the tool for an album split exhausts the trial before finishing a single project and must upgrade or leave. File duration is hard-capped at 10 minutes and file size at 100 MB, so DJ sets, live recordings, or extended mixes cannot be processed as single files; workarounds require manually cutting audio before upload, adding steps that defeat the speed advantage. There is no API and no batch processing capability at any tier, which means any team that needs to automate stem separation — even a small one running nightly remix pipelines — has to replace this tool with a service that exposes a programmatic interface, such as a self-hosted Demucs instance or a vendor API. No self-hosted option exists, so teams operating under data residency or content confidentiality requirements cannot use the service at all — unreleased tracks processed here transit Clumi's servers.	The tool is macOS-only — a Windows-based post-production team cannot use it at all, and that is a hard stop that sends them to browser-based or cross-platform audio search alternatives regardless of how well the search quality performs. Metadata writing and the local API are paid-only features, which means the free tier is a search-only evaluation tool — teams that discover they need to push metadata back to files or integrate with a DAW hit a paywall before they can run a real production workflow test. Semantic search quality is bounded by the metadata and audio content Curlo can analyze in your existing files; libraries with years of inconsistent naming and stripped metadata will return noisy results until a manual cleanup pass is done — that remediation work falls entirely on the user. There is no shared or cloud-synced library mode described in the vendor documentation, so a team of three editors who need to search the same asset library from different machines cannot use Curlo as a shared source of truth — they either duplicate the library on each machine or switch to a team-oriented DAM solution.

Bottom line

Only Curlo exposes a public API. Choose based on which difference matters most for your workflow.
