a writing tool that uses the gpt-3 api and that can be integrated on a html website. in javascript

To create a writing tool that uses the GPT-3 API, you first need to obtain an API key from OpenAI. Once you have this, you can use JavaScript to make API requests to generate text using GPT-3. Here's a basic example that sends a prompt to the API and prints the generated text:

index.tsx
const apiKey = 'YOUR_API_KEY';
const apiUrl = 'https://api.openai.com/v1/engines/davinci-codex/completions';

async function generateText(prompt) {
  const response = await fetch(apiUrl, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${apiKey}`
    },
    body: JSON.stringify({
      'prompt': prompt,
      'max_tokens': 1024,
      'temperature': 0.7
    })
  });
  
  const data = await response.json();
  return data.choices[0].text;
}

// Example usage
generateText('The quick brown fox jumped over the lazy dog.')
  .then(text => console.log(text))
  .catch(error => console.error(error));

To integrate this into an HTML website, you can create a form where users can enter their writing prompts and then display the generated text on the page. Here's an example:

<!DOCTYPE html>
<html>
  <head>
    <title>GPT-3 Writing Tool</title>
    <script>
      const apiKey = 'YOUR_API_KEY';
      const apiUrl = 'https://api.openai.com/v1/engines/davinci-codex/completions';

      async function generateText(prompt) {
        // Same code as above
      }

      async function handleSubmit(event) {
        event.preventDefault();
        const promptInput = document.getElementById('prompt-input');
        const resultDiv = document.getElementById('result');

        try {
          const text = await generateText(promptInput.value);
          resultDiv.innerText = text;
        } catch (error) {
          resultDiv.innerText = `Error: ${error.message}`;
        }
      }
    </script>
  </head>
  <body>
    <h1>GPT-3 Writing Tool</h1>
    <form onsubmit="handleSubmit(event)">
      <label for="prompt-input">Enter your writing prompt:</label>
      <textarea id="prompt-input"></textarea>
      <button type="submit">Generate</button>
    </form>
    <div id="result"></div>
  </body>
</html>

This example creates a form with a textarea where users can enter their writing prompts. When the form is submitted, the handleSubmit function is called, which sends the prompt to the generateText function and displays the result on the page.
