What is Whisper?

Whisper transcribes audio recordings, recognizes the spoken language and translates recordings into English. It serves people who want to obtain transcriptions or produce subtitles with timestamps from audio.

According to its documentation, Whisper lets you:

  • transcribe an audio recording
  • recognize the spoken language
  • translate a recording into English
  • produce subtitles with timestamps

We file it under Speech to text, the category of tools to transcribe audio to text, and it also overlaps with aI translation and subtitles and dubbing. The category lists 15 verified tools on this site.

The publisher is OpenAI. The service launched in 2022, which gives it some track record.

Who is it for?

It is mostly useful to these profiles: developers, podcasters, video creators, and researchers. The need it covers is simple to state: transcribe audio to text.

Whisper is a good candidate if:

  • you want to try before paying
  • you plan to connect it to your tools or automations through its API
  • you want to read the code or host it yourself

The best test is a concrete case from your daily work: if the tool does not beat your current method within a week, move on to an alternative.

How much does Whisper cost?

Pricing model: open source (public code). A free plan is offered, usually limited in volume or features.

The first paid plan costs $0.01 pay as you go (whisper-1 API, per minute of audio; model marked as deprecated but still offered. Free local execution), according to the pricing page, checked on October 24, 2026.

Data and privacy

According to its privacy policy, data is processed in several regions depending on the plan.

Exporting your content: yes (details on the official site). Being able to get your data back makes switching tools easier later.

Three habits apply to every AI tool:

  • turn off the use of your content for training if the option exists
  • use a work account separate from your personal account
  • review everything the tool produces before publishing or sending it

Whisper runs on: Windows, macOS, Linux, and API.

Interface languages are not specified.

A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
