Prompts in the background:

  const systemPrompt = `
    Convert the following PDF page to markdown. 
    Return only the markdown with no explanation text. 
    Do not exclude any content from the page.
  `;

For each subsequent page: messages.push({ role: "system", content: `Markdown must maintain consistent formatting with the following page: \n\n """${priorPage}"""`, });

Could be handy for general-purpose frontend tools.
