# Playground

> Test Gladia models and features in the browser before you integrate

[Gladia's playground](https://app.gladia.io/?utm_campaign=197609689-Website\&utm_source=documentation\&utm_content=sign-up) lets you try Speech-To-Text in the browser: mic stream, local upload, or remote URL. Compare models and features on your audio before you integrate.

<Steps>
  <Step title="Select your audio source">
    Choose your audio source (mic stream or local file upload).

    Then proceed to the next step.
  </Step>

  <Step title="Select features">
    Select <Tooltip tip="For the full feature list, see the Features section">some of
    the options</Tooltip> Gladia provides. \
    In this example we enable **named entity recognition**.

    <Note>
      Only a subset of API features is available in the playground. For advanced testing,
      see the [API documentation](/api-reference/).

  </Step>

  <Step title="Talk to Gladia">
    Click **Start transcribing** to see your voice in the Transcription tab.

    </Frame>
  </Step>

  <Step title="Transcribe">
    The Transcription tab shows a readable result. The JSON tab shows the same payload you would get from an API call.

## Test models before integrating

Try the features you need (e.g. diarization or NER) and compare [Solaria-3 vs Solaria-1](/chapters/introduction/models) on your audio. Check both the readable transcript and the JSON tab.
