What Is Whisper AI Dictation?
Whisper AI dictation uses OpenAI's open-source Whisper speech recognition model to convert speech to text. JesType is a desktop app that runs Whisper entirely on your Mac or Windows PC with no internet connection, no API key, and no cloud processing. Whisper supports 99 languages and multiple model sizes for different accuracy and speed trade-offs. JesType costs €14.95 one-time.
What Is OpenAI Whisper?
Whisper is an open-source automatic speech recognition (ASR) model released by OpenAI. It was trained on 680,000 hours of multilingual audio data, making it one of the most capable speech recognition models ever created. Because Whisper is open-source, it can be run locally on any computer without requiring an OpenAI account or API access.
Whisper supports 99 languages, handles accented speech well, and comes in multiple sizes — from the fast, lightweight Tiny model to the highly accurate Medium model. This makes it suitable for everything from quick voice notes to professional multilingual transcription.
How JesType Uses Whisper
JesType packages Whisper into a native desktop application that runs entirely on your device. Here is what that means in practice:
No API Key Needed
JesType includes the Whisper model runtime. You do not need an OpenAI account, API key, or any cloud service. Download the model once and it works offline forever.
Complete Privacy
Your audio is processed by the Whisper model on your own CPU. No audio data is ever sent to OpenAI, JesType servers, or any third party.
No Per-Use Cost
The OpenAI Whisper API charges $0.006 per minute of audio. JesType runs Whisper locally for €14.95 total — no per-minute charges, no usage limits.
System-Wide Integration
Unlike running Whisper from the command line, JesType provides a hold-to-record shortcut that inserts text at your cursor in any application.
Whisper Model Sizes
Whisper comes in multiple sizes. Larger models are more accurate but require more RAM and processing time. JesType lets you download and switch between models at any time.

| Whisper Tiny | 39M | ~1 GB | Fastest | Quick notes, low-power devices |

| Whisper Small | 244M | ~2 GB | Moderate | Balanced accuracy and speed |

Frequently Asked Questions
Do I need an OpenAI API key to use Whisper with JesType?
No. JesType runs Whisper entirely on your device using the open-source model weights. There is no API key, no cloud connection, and no OpenAI account required. You download the model once and it runs locally forever.
Which Whisper model size should I choose?
For most users, Whisper Small offers the best balance of accuracy and speed. If you need faster transcription and primarily dictate in English, try Parakeet instead. Whisper Medium provides the highest accuracy but requires more RAM and processing time.
How many languages does Whisper support?
Whisper supports 99 languages including English, Spanish, French, German, Chinese, Japanese, Arabic, Hindi, and many more. It can also auto-detect the language being spoken.
