LALAL.AI vs Undetectr

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. Undetectr publishes a starting price ($39); LALAL.AI does not. Only LALAL.AI has a free tier. Only LALAL.AI ships a public API.

What our research says

LALAL.AI

Still one of the cleanest stem splitters per minute you can buy, and the one-off packs suit people who need this occasionally rather than every month.

Pros

  • Separation quality is consistently near the top of this category
  • Minutes can be bought outright, so light users avoid a subscription
  • Desktop apps, a VST plugin and an API alongside the browser tool
  • 10 free minutes are enough to judge output quality before paying

Cons

  • Subscriptions are billed in euros, so the USD cost moves with the exchange rate
  • Free tier is relaxed-queue only and therefore slow
  • VST plugin, batch processing and API are all locked out of the free tier
  • Two parallel pricing schemes, packs and subscriptions, make comparison awkward

Undetectr

Undetectr's premise is narrow and specific: strip whatever lets a distributor detect a track as AI-generated. If the flat one-time $39 pricing holds up, that's an unusual and buyer-friendly structure for this kind of tool. Everything here comes from search-indexed content rather than a direct site visit, since the live site blocked every fetch attempt during this check, so treat the specifics as reported, not confirmed. The larger issue is that the product exists to defeat AI-content disclosure, which conflicts with the policies of platforms that require it.

Pros

  • Described as a flat one-time $39 payment rather than a recurring subscription
  • Says it accepts the three formats musicians actually export — MP3, WAV, FLAC
  • A narrow, specific job rather than a bundled do-everything audio tool

Cons

  • The live site blocked every direct fetch attempt during this check, so none of its claims could be confirmed firsthand
  • No company name, location, or accountable entity is disclosed anywhere found
  • The product's purpose directly conflicts with AI-content disclosure policies on the platforms a musician would distribute to

Which one fits

Choose LALAL.AI if you need
