Create tasks from meeting transcription
Overview
This example demonstrates how you can create task assignments based on a transcription of meeting recording.
Example
<?php
$loader = require 'vendor/autoload.php';
$loader->add('Cognesy\\Instructor\\', __DIR__ . '../../src/');
use Cognesy\Instructor\Enums\Mode;
use Cognesy\Instructor\Instructor;
// Step 1: Define a class that represents the structure and semantics
// of the data you want to extract
enum TaskStatus : string {
case Pending = 'pending';
case Completed = 'completed';
}
enum Role : string {
case PM = 'pm';
case Dev = 'dev';
}
class Task {
public string $title;
public string $description;
public DateTimeImmutable $dueDate;
public Role $owner;
public TaskStatus $status;
}
class Tasks {
public DateTime $meetingDate;
/** @var Task[] */
public array $tasks;
}
// Step 2: Get the text (or chat messages) you want to extract data from
$text = <<<TEXT
Transcription of meeting from 2024-01-15, 16:00

PM: Hey, how's progress on the video transcription engine?
Dev: I've got basic functionality working, but accuracy isn't great yet. Might need to switch to a different API.
PM: So the plan is to research alternatives and provide a comparison? Is it possible by Jan 20th?
Dev: Sure, I'll make it available before the meeting.
PM: The one at 12?
Dev: Yes, at 12. By the way, are we still planning to support real-time transcription?
PM: Yes, it's a key feature. Speaking of which, I need to update the product roadmap. I'll have that ready by Jan 18th.
Dev: Got it. I'll keep that in mind while evaluating APIs. Oh, and the UI for the summary view is ready for review.
PM: Great, I'll take a look tomorrow by 10.

print("Input text:\n");
print($text . "\n\n");
// Step 3: Extract structured data using default language model API (OpenAI)
print("Extracting structured data using LLM...\n\n");
$tasks = (new Instructor)->respond(
messages: $text,
responseModel: Tasks::class,

// Step 4: Now you can use the extracted data in your application
print("Extracted data:\n");
