OffgridStem vs. Moises, LALAL.AI, StemSplit, and AudioShake: Which Stem Splitter Keeps Your Audio Private?
September 2026
AI stem separation has moved from specialist desktop software to everyday mobile apps and browser tools. The question is no longer whether a product can pull vocals off a track — most can. The real differences are where the processing happens, how many stems come out the other end, what it costs over time, and what happens to your audio once you've uploaded it.
We looked at Moises, LALAL.AI, StemSplit, and AudioShake against OffgridStem's on-device approach — six stems, processed entirely on the iPhone, with nothing sent anywhere.
The five compared
Moises — the deepest feature set, built around cloud processing
Moises separates up to 27 documented stem types and pairs that with chord detection, pitch and tempo changes, a metronome, and rehearsal tools. It has a free tier with limited uploads; independent 2026 pricing reports place paid access from around $3.99/month, though store pricing varies by region.
What to know
- Built as a practice companion first, stem splitter second — most useful if you also want chord and tempo tools
- Cloud/web-based processing — your file is uploaded for separation
- Pricing and upload quotas vary by platform and region, making direct comparison difficult
LALAL.AI — broad stem count, cloud by default
LALAL.AI documents up to 10 stem types with batch processing on paid tiers. Lite runs $9.99/month or $90/year; Pro is $19.99/month or $180/year and is reported to add VST and API access, plus an optional local-processing mode.
What to know
- Standard workflow processes audio online — a local option is reported only on the Pro tier
- Usage is measured in minutes, so effective cost depends on how many outputs you request
- Strongest fit for production pipelines that need batch jobs, API access, or plugin integration
StemSplit — pay-as-you-go, browser-based
A credits system rather than a subscription: $2 for 10 minutes, $5 for 30, $12 for 100, or $30 for 300 — credits don't expire. Vocal and instrumental outputs are clearly listed; the full plan scope is worth checking before purchase.
What to know
- Browser/cloud processing — audio is uploaded for each job
- Works out to about $0.10/minute on the largest pack, competitive for occasional use
- Narrower output scope than Moises or LALAL.AI
AudioShake — professional catalogues, priced accordingly
A cloud service aimed at labels, publishers, and licensing workflows rather than individual creators. Reported Indie plans range from $20/month for 4 stems to $60/month for 20 stems.
What to know
- Cloud professional service — built for commercial, contract-backed workflows, not casual use
- By far the most expensive option here on a per-stem basis
- Makes sense for catalogue-scale or licensing work, less so for a single track
OffgridStem — six stems, entirely on your iPhone
Splits a track into six stems — vocals, drums, bass, piano, guitar, and other instruments — using on-device machine learning. There's no upload step because there's no server in the workflow at all.
What's good
- Audio never leaves the device — separation happens fully offline, including in Airplane Mode
- Free to try with a limited number of separations per month; Pro is a one-time £24.99 purchase, not a subscription
- No account required to use the app
- A self-conducted network audit in August 2026 found no outbound connections during a full workflow test
Where it trades off
Six stems is fewer than Moises's 27 or LALAL.AI's 10 documented types, and OffgridStem doesn't try to be a practice tool with chord detection or tempo changes. It's built to do one job — separate a track privately, on the device you already have — rather than compete on feature count.

Why we built OffgridStem this way
For unreleased songs, client demos, or a mix you don't want sitting on someone else's server, the upload step is the whole risk. Every cloud splitter — however good the separation — requires your file to leave the device before you can do anything with it.
OffgridStem asks a simpler question: if the iPhone can run the model, why send the audio anywhere at all? Six stems covers the tasks most creators actually need — an instrumental, an isolated vocal for a remix, rebalanced drums and bass in a demo — without a queue, an account, or a recurring bill.
We're not trying to out-feature Moises or LALAL.AI. If you need 27 stem types or chord detection, they're the better fit. If the first question is "can I do this without uploading the track," that's the problem OffgridStem was built to solve.
Download OffgridStem on the App StoreFrequently asked questions
Do Moises, LALAL.AI, StemSplit, and AudioShake upload my audio to a server?
Yes, by default. All four are built around cloud or browser-based processing — your file has to leave your device so a remote model can separate it, then the result is downloaded back. LALAL.AI's Pro plan is reported to offer an optional local-processing mode, but its standard workflow, like the others, is cloud-based.
How many stems can each tool separate?
OffgridStem separates 6 stems (vocals, drums, bass, piano, guitar, other instruments). Moises documents up to 27 stem types alongside practice tools like chord detection and tempo changes. LALAL.AI offers up to 10 stem types. StemSplit and AudioShake focus on a smaller set of vocal, drum, bass, and instrument outputs.
Which option is cheapest for regular use?
It depends on volume. OffgridStem Pro is a one-time purchase of £24.99 with no recurring cost, which becomes cheaper the more you use it over time. StemSplit's pay-as-you-go credits (from $2 for 10 minutes to $30 for 300 minutes, non-expiring) suit occasional use. Moises, LALAL.AI, and AudioShake are subscription-based, with AudioShake's professional plans priced well above the others.
How is OffgridStem different?
OffgridStem separates a track into 6 stems entirely on the iPhone, using on-device machine learning. Nothing is uploaded, there's no account, and it works fully offline including in Airplane Mode. It's a one-time £24.99 purchase for the Pro tier rather than a subscription. See our Privacy Policy for details.
