StudyGlen
Generate diagram-rich quizzes from PDFs, scans, and pasted notes, then study and export them.
Strong quiz generator, but mixed on flashcards and polish.
- You need quizzes generated from PDFs, scanned notes, or pasted study material.
- You want MCQ, True/False, and Short Answer questions with explanations and source context.
- You care about inline diagrams and broad export options such as PDF, Word, CSV, Anki, or QTI/LMS.
- You need reliable flashcard deck creation today; validation failed in this run.
Our take
StudyGlen handled typed PDFs, scanned notes, and pasted text, and its clearest strength is embedding AI-generated diagrams directly inside quiz questions. The study-mode loop and export options are solid, but flashcard generation failed validation in this run, the free tier is tightly capped, and one short-answer question leaked an internal prompt tag into the visible stem.

Feature-by-Feature Breakdown
Multi-format Material IntakeVerified on PDF, scan, and pasted text▾
Feature tested: Multi-format Material Intake
Result: Passed
Verdict: Verified on PDF, scan, and pasted text
Expected behavior: StudyGlen can generate quizzes from uploaded PDFs/images and from pasted text. In the tested run it handled a typed biology PDF, a handwritten/scanned notes upload, and a long pasted-text sample.
Test case: PDF document → Image
Input type: PDF document
Input used: Input artifact (PDF document): NCERT Input 1.pdf — a biology chapter on sexual reproduction in flowering plants. — input1_primary.pdf
Observed output: Output artifact (Image): A typed PDF produced a True/False quiz item with an explanation panel and quoted source context. — out1_truefalse_explanation.png

What changed: Text prompt transformed into Image
Why it matters / Conclusion: Typed PDFs, handwritten/scanned notes, and pasted text all worked in the tested flow. The OCR/scanned-file warning appeared in the capture set, but it should be treated as a generic notice rather than a proven handwriting-specific detector.
StudyGlen can generate quizzes from uploaded PDFs/images and from pasted text. In the tested run it handled a typed biology PDF, a handwritten/scanned notes upload, and a long pasted-text sample.

Inline AI-Generated DiagramsDistinctive and useful, but not perfectly clean▾
Feature tested: Inline AI-Generated Diagrams
Result: Partial
Verdict: Distinctive and useful, but not perfectly clean
Expected behavior: StudyGlen can embed AI-generated diagrams and flow-style visuals directly inside quiz questions when a topic benefits from visuals. In the biology run it produced diagrammed questions for topics like Vallisneria pollination, apomixis/polyembryony, and megasporogenesis.
Test case: Text prompt → Image
Input type: Text prompt
Input used: Input artifact (Text prompt): Pollination-sequence question
Observed output: Output artifact (Image): A multiple-choice question included a labeled diagram about water pollination in Vallisneria. — out1_diagram_question_vallisneria.png

Output artifact: Output artifact (Image): The Generate AI image control was visible on a short-answer question but locked. — shortanswer_generateaiimage_locked.png
What changed: Text prompt transformed into Image
Why it matters / Conclusion: This is StudyGlen's clearest differentiator: the diagrams are integrated into the quiz itself rather than bolted on afterward. The visual layer is not flawless, though — the tested biology set showed repeated motifs, one locked manual image control, and one internal prompt tag leak.
StudyGlen can embed AI-generated diagrams and flow-style visuals directly inside quiz questions when a topic benefits from visuals. In the biology run it produced diagrammed questions for topics like Vallisneria pollination, apomixis/polyembryony, and megasporogenesis.
