AI Question Generation

What it does

Send a PDF, DOCX, PPTX, or TXT file. The AI engine reads it, identifies the key concepts, and produces structured exam questions with answers and explanations. Use it inside your LMS, Moodle plugin, or any internal tool.

Highlights

• 15 question types — multichoice, T/F, short answer, essay, fill-in-blanks, matching, numerical, ordering, hotspot, labeling, matrix, calculated, recording, bowtie, interactive.
• 15 languages — English, Arabic, French, Spanish, Urdu, Hindi, Chinese, and more.
• Difficulty control — easy / medium / hard / mixed.
• Smart deduplication — small repeated batches automatically dedupe so Moodle plugins never get repeats.
• Per-package quota — every entity has its own subscription limit + extra pool fallback.
• Audit trail — every request stores who paid, from which subscription.

How to integrate

1. Get your API key from the admin panel → Entities → your row.
