How long does switching from OpenAI Whisper API actually take?

An evening for most accounts. The export from OpenAI Whisper API is the slow step - the import side runs in minutes once the field mapping is settled. Larger teams (50+ seats with custom field schemas) sometimes split it across two sessions: import first, reorganise the next day.

Will I lose data when I switch?

Nothing structural. The CSV/JSON export from OpenAI Whisper API preserves the data: records, fields, history, and attachments come over intact. What doesn't transfer is anything tied to OpenAI Whisper API-specific UI metadata (custom views, saved searches, in-app annotations) - those don't sit in the export, they sit in the source product's UI. Plan an evening to rebuild your most-used views once you're in.

What about my existing OpenAI Whisper API subscription?

Run both side-by-side until you're confident, then cancel OpenAI Whisper API from their side. We don't lock you in - export from Sprachmemo is one click in account settings, same as import.

Is the import path free?

The import button is open on every plan, including the free tier - we don't paywall the way out of a competitor. The data going in still has to fit your plan's per-type quotas (the free-tier caps are listed on /sales); paid plans raise those caps. If you're moving a large set, check the caps first or write to /support and we can advise.

Can I get help with the switch?

Yes. Write to /support - both founders see those threads directly. Reply within a working day. For the field-mapping itself we typically resolve things in one or two exchanges; if your dataset is unusually large or OpenAI Whisper API's export shape is unfamiliar, we'll say so up front.

Sprachmemo is what people use when OpenAI Whisper API stops fitting. Below is the honest side-by-side - same product surface, different posture: hosted in Germany, no third-party trackers, one honest price - plus the migration mechanics that decide whether the switch lands in an evening or in a quarter.

At a glance

If you're building a tool yourself and ship audio to OpenAI's hosted endpoint, Whisper is hard to beat on raw accuracy for English. Sprachmemo is the choice if you don't want to wire transcription yourself, don't want a US data-processor in the loop, and primarily speak German. The two products serve different jobs.

Switching

What moving from OpenAI Whisper API actually looks like

The switch goes in three rough phases: export from OpenAI Whisper API, import into Sprachmemo, and reorganise what came over. Most people allocate an evening for it. The export side is where the time goes - OpenAI Whisper API hands you a CSV/JSON dump and the field mapping isn't always obvious; once that's resolved the import is a couple of minutes. We don't paywall the import path or pretend it's a pro-only feature, and you can run both side-by-side while you decide.

Sprachmemo vs OpenAI Whisper API: feature comparison

	Ours Sprachmemo	Theirs OpenAI Whisper API
Surface	Browser app + transcription	API only - you build the UI
Privacy posture	Audio on EU servers, no training	Audio to OpenAI US infra, OpenAI's policy applies
German accuracy (clean studio audio)	Vosk Large: very good	Excellent
German accuracy (noisy phone audio)	Solid	Strong
Self-hosted option	We host it - or run the same Vosk yourself	Open-weights Whisper exists, but you have to run it
Cost for 60 min/month	Free tier covers it	≈ 0,36 USD via the API (audio only, no UI)
Cost for 60 hours/month	Basis or Power tier	≈ 21 USD via the API (audio only)
Editable transcript + audio archive

When to pick which

Pick Sprachmemo when

You want a working app, not a SDK. Tap the circle, get a transcript, edit it.

Your audio shouldn't transit US infrastructure (clinical, legal, journalistic, kids).

German is your primary language and you want it to work without a configuration step.

Pick OpenAI Whisper API when

You're a developer integrating speech-to-text into a product you ship yourself.

Your audio has unusual characteristics (heavy accents, low SNR, non-German non-English languages).

You want the absolute state of the art on accuracy and the policy footprint isn't a blocker for your use case.

The two products do different jobs

Whisper is an API. To use it you write code, manage an API key, handle rate limits, store the transcripts somewhere, deal with audio formats, build a UI for your user. Sprachmemo is a finished app. To use it you tap a green circle. Comparing them is mostly a comparison of how much work you want to do. If the answer is 'I'm a developer and I'll happily do that work to integrate Whisper into something I'm building', Whisper is in a different category and we'd recommend it. If the answer is 'I want to record a voice note and read it back', Whisper isn't actually the product you want; you want a product built on top of something like Whisper or Vosk.

Vosk is genuinely good at German

The German Vosk Large model is built on Kaldi acoustic models trained on hundreds of hours of clean and noisy German speech. For studio-quality input it's effectively indistinguishable from Whisper on common vocabulary. Where Whisper is meaningfully better is rare proper nouns and code-switched English-in-German speech (calling 'OpenAI' or 'Kubernetes' in the middle of a German sentence). We accept that gap deliberately - the audience that needs frequent code-switching also tends to be the audience that's OK shipping audio to an English-first vendor.

Step by step

Export from OpenAI Whisper API

Find the export option in OpenAI Whisper API's account settings. Most tools provide a CSV or JSON download. Save the dump locally - that's the source of truth for the next step.

Account settings → Export / Download data

Pick the broadest format the tool offers (usually JSON)

Map fields in Sprachmemo

Open the import tool in Sprachmemo. OpenAI Whisper API's field names rarely match Sprachmemo' 1:1; the import flags any unmapped columns so you can pair them up before anything commits.

Account settings → Import

Resolve the mapping prompts the tool surfaces

Run the import

Run the import. Sprachmemo shows a preview of the first parsed rows in the import dialog so you can sanity-check the column mapping + a sample of records before anything commits. If you're nervous about a large dump, import a small subset first, verify it landed the way you expected, then run the full file.

Re-create your views, tags, saved searches

OpenAI Whisper API-specific UI metadata (custom views, saved filters, in-app annotations) doesn't transfer with the data export. Spend an evening rebuilding the views you used most - usually a 30-minute job once you've done it once.

Cancel OpenAI Whisper API when you're confident

Run both side-by-side for a couple of weeks if you want to be sure. When you're confident, cancel the OpenAI Whisper API subscription from their side. Sprachmemo keeps your export option self-serve in account settings - no lock-in either direction.
