Moises App
Pros
- + Independent pitch and tempo control plus chord/key/BPM detection makes it a daily practice tool, not just a splitter
- + Drum separation outperformed the field in the community benchmarks Chartlex compiled (~9.1 dB SDR) and held transients in my listening tests
- + Premium at about $35.88/year (July 2026 web check) is extraordinary value for the full practice toolkit
- + Full feature parity across iOS, Android, web and desktop — the same library wherever I opened it
- + Hi-Fi 48kHz/24-bit exports, guitar/piano separation and AI mastering with reference-track mode on Pro
Cons
- - Vocal stems trail LALAL.AI's Phoenix (~9.8 vs ~10.4 dB SDR in compiled benchmarks) and carried bleed on dense choruses in my tests
- - Pricing is fragmented: web pricing page now requires login, app-store SKUs run higher ($5.99 Premium monthly on iOS per Sensor Tower)
- - Free tier is a five-upload demo with ads — not a working plan
- - No VST plugin, no DAW session export, and no self-serve API on consumer plans
- - Extreme time-stretch settings introduce audible warble on sustained notes
AssemblyAI
Pros
- + Transparent, published rate card: $0.15/hr for Universal-2 and $0.21/hr for Universal-3.5 Pro at time of writing (assemblyai.com/pricing.md), with worked examples showing exactly how add-ons stack
- + $50 in free credits at signup with no credit card required, so I could benchmark real audio before paying anything
- + Guardrails (PII audio/text redaction, profanity filter, content moderation) are first-party add-ons instead of a second vendor contract
- + EU data residency at the same price as US processing — no GDPR surcharge in my review of the rate card
- + Voice Agent API bundles STT + LLM + TTS + turn detection at one $0.075/min rate, which I found cheaper than assembling the same pipeline by hand
Cons
- - No end-user app: everything runs through the API, so non-developers have no path in
- - Streaming bills by open-connection time, not audio sent — an idle socket left open after a call keeps charging in my testing
- - Add-ons stack on the base rate until a 'cheap' transcript approaches $0.40–$0.60/hr for the feature set most teams want
- - Long-file processing is async only; no synchronous option for large uploads
- - Legacy Auto Chapters and Summarization add-ons are deprecated and can fail silently on newer models per the vendor's own pricing reference
