Why Marksy Excels for IB Grading

Purpose-Built Specialization

While ChatGPT is an impressive general-purpose AI, Marksy is specifically designed for IB assessment grading. This specialization means built-in IB rubrics, subject-specific training, and workflows optimized for teachers—no prompt engineering required.

Time-Saving Efficiency

Bulk grading 15 assignments simultaneously versus one-at-a-time processing makes a massive difference for teachers. What takes hours with ChatGPT takes minutes with Marksy, without sacrificing quality or consistency.

Consistency & Standards

ChatGPT's grading quality varies based on prompt quality and can be inconsistent. Marksy is calibrated to IB standards, ensuring every assessment receives the same rigorous, fair evaluation aligned with official criteria.

Better Value for Grading

For dedicated IB grading needs, Marksy's Pro Plan offers superior value with 200 monthly gradings, bulk processing, and specialized features—all for less than ChatGPT Plus, which lacks grading-specific tools.

Frequently Asked Questions

Can I use ChatGPT for IB grading instead of Marksy?
While ChatGPT can assist with grading through custom prompts, it lacks specialized IB features like built-in rubrics, bulk grading, visual criteria mapping, and AI detection. You'd need to manually input rubrics, grade one assignment at a time, and format results yourself. Marksy is purpose-built for IB grading efficiency and consistency.
Is Marksy's AI grading more accurate than ChatGPT?
For IB assessments, yes. Marksy is specifically trained and calibrated on IB rubrics and standards, ensuring consistent, accurate grading aligned with official criteria. ChatGPT's accuracy depends heavily on prompt quality and lacks IB-specific training. While ChatGPT is excellent for general tasks, specialized tools deliver better results for specialized needs.
Why would I choose ChatGPT over Marksy?
ChatGPT is better if you need a versatile AI assistant for multiple purposes: creative writing, coding, general research, image generation, or conversational AI. If you're only grading IB assessments, Marksy offers better value and efficiency. Many educators use both: Marksy for grading and ChatGPT for other teaching tasks.
Can ChatGPT do bulk grading like Marksy?
No. ChatGPT processes one conversation at a time. To grade multiple assignments, you'd need to upload and prompt for each submission individually, which is time-consuming. Marksy's bulk grading feature allows you to upload up to 15 assignments simultaneously and receive consistent grading across all submissions.
Which is more cost-effective for IB users?
For dedicated IB grading, Marksy is more cost-effective. The Pro Plan (~€14.99/month) provides 200 IB-specific gradings with bulk processing, compared to ChatGPT Plus ($20/month) which requires manual prompting for each assignment. ChatGPT Pro ($200/month) offers unlimited usage but is significantly more expensive for grading-focused needs.
Does Marksy have the same conversational abilities as ChatGPT?
No. Marksy is specialized for IB assessment grading and doesn't function as a general conversational AI. It excels at grading tasks but won't help with creative writing, coding, or general questions. ChatGPT is the better choice for versatile AI assistance beyond grading.
Can I upload PDFs to both platforms?
Marksy natively supports PDF uploads with annotation and highlighting features on all paid plans. ChatGPT offers PDF analysis on Plus and Pro tiers, but without grading-specific features like criteria mapping or IB rubric integration. Marksy's PDF handling is optimized for assessment grading workflows.
