Clumi vs TrainScription

Clumi and TrainScription 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.

TrainScription

TrainScription runs Whisper entirely in your browser via WebAssembly, processing audio in 5-second chunks that are never written to disk and never leave the machine. The Phonetic Brain lets you highlight a misfire — a misspelled proper noun, an industry term Whisper mangles — and that correction fires automatically on every future session. Browser Tab mode covers Google Meet, Teams web, Zoom web, and any other browser-based call; Full Desktop mode, which captures all system audio, is a paid-only feature. The free tier caps sessions, so heavy users who record three or four long calls daily will hit that ceiling and either upgrade or find the cap disruptive. There is no API, no mobile path, and no way to push transcripts into a downstream system without manual export.

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.	All transcription runs locally via WebAssembly with zero network calls during a session, which means audio from privileged conversations — legal strategy, M&A discussions, compliance reviews — never touches a third-party server. No bot joins the call as a participant in either mode, so the other party has no indication the conversation is being transcribed, which matters in client-facing or sensitive negotiations. The trainable Phonetic Brain permanently maps phonetic misfires to correct spellings after a single correction, so domain-specific terms — proper nouns, filing codes, product names — stop breaking after the first session that introduces them. The one-time payment for Pro unlocks unlimited sessions and Full Desktop mode with no recurring charge, which removes the cost accumulation problem for professionals who transcribe daily. Sessions are automatically segmented and grouped in Recovery with full post-session correction capability, so a dropped connection or long meeting does not mean losing the transcript or having to re-review from scratch.
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 free tier caps session count, and professionals running three or more long calls per day will exhaust the free allowance quickly — the next step is the paid upgrade or accepting interrupted workflows mid-week. There is no API and no automated export path, so any team that needs transcripts to arrive in a CRM, document management system, or case file without a manual download step has to build that handoff themselves — and at the point where that overhead becomes a daily tax, teams move to a cloud transcription service that offers a webhook or native integration, accepting the privacy trade-off in exchange. Full Desktop mode, which is required for native app meeting clients like Teams desktop or Zoom desktop, is a paid-only feature — teams on those apps who want to evaluate the tool on the free tier cannot test the primary capture mode they would actually use in production. Whisper's accuracy on heavily accented speech or fast cross-talk degrades, and while the Phonetic Brain corrects recurring proper-noun errors, it does not address the underlying model's accuracy ceiling — teams transcribing multilingual calls or high-interruption conversations will find a residual error rate that manual correction does not eliminate.
