Turn audio into text. Easy and fast.

Murmel works on a subscription basis. You start with 14 days of Basic for €0.01 — with full access right away (720 minutes per month, speaker identification, all exports). The €0.01 is only to confirm your payment method. After 14 days Basic automatically continues at €10.89 per month (€9.00 excl. VAT), unless you cancel before then. One day before it ends you'll get a reminder by email.

Murmel is trained specifically for the Dutch language, outperforming generic models-even with heavy accents or professional jargon.

Murmel is 100% hosted in the Netherlands. All processing occurs on Dutch servers, and we exclusively work with European partners. Using our API, you can utilize the 'in-transit' or 'do-not-save' feature, ensuring both audio and transcription are immediately destroyed. In the Studio environment, all data is automatically deleted after 7 days by default, or instantly when you delete it yourself. Furthermore, transcriptions are never used for AI training unless you give explicit permission (for example, to improve a custom model).

You can upload most standard audio and video formats, including MP3, WAV, MP4, M4A, WEBM, FLAC and OGG.

Yes, we offer a comprehensive REST API so you can seamlessly integrate our Dutch speech-to-text service into your own applications.

Extremely fast. Our optimized GPU infrastructure processes audio at 35x realtime speed. A one-hour recording is fully and accurately transcribed in less than 2 minutes.

Highly sustainable. We use Leafcloud's green GPU infrastructure in Amsterdam. Since these servers are housed in apartment complexes, the residual heat from running our AI models directly warms shower water and buildings, actively reducing natural gas usage.

One credit equals one minute of transcription. There are two types: (1) subscription credits that come with your monthly plan and reset each month, and (2) prepaid wallet credits that are valid for 6 months from the purchase date. When you upload audio, credits are deducted based on the file's duration.

Your subscription credits reset each month on the first day of your billing cycle; unused subscription credits do not roll over. Prepaid wallet credits work differently: they remain valid for 6 months from the purchase date and carry over until you use them up or they expire.

Upon upgrading, you immediately pay the prorated difference for the remainder of your current period and receive the higher monthly credits right away. Upon downgrading, your plan changes at the next billing cycle - you keep your current plan until the end of the current month. If you cancel, you retain access until the end of your current billing period. Prepaid wallet credits are always valid for 6 months and are not affected by subscription changes - they remain usable even after cancellation.

Yes, you can cancel at any time without a notice period — including during the trial. If you cancel during the 14-day trial, you won't be charged. After that you keep access and your subscription credits until the end of your current billing cycle. Any prepaid wallet credits remain valid for the full 6 months.

You can see your subscription usage on the Studio page above the history and on your profile page under "Usage". Your prepaid wallet credits appear as a separate tile on both the profile and developer pages, including the expiry date.

We accept iDEAL, credit cards (Visa, Mastercard), Bancontact, and SEPA direct debit. All payments are processed securely. All prices are excluding 21% VAT; VAT is added at checkout.

If you have prepaid wallet credits, they are automatically used once your monthly subscription credits are exhausted - no extra invoicing. If you have no wallet credits but have enabled 'extra usage' opt-in in your profile, the excess is billed at the end of the billing period at your plan's overage rate. The higher your plan, the lower the rate per extra minute.

Yes. You can buy prepaid credits at €0.02 per minute (excl. VAT). Pick any amount from €5 upwards. Credits are valid for 6 months and expire afterwards. No monthly commitment. A subscription is cheaper per minute for regular use — it pays off from about 450 minutes per month.

Your monthly subscription minutes first (they reset each month), then your prepaid wallet credits (valid 6 months). This way you never accidentally burn through your more expensive prepaid credits.
