Mark This For Me

Mark This For Me occupies a narrow but useful niche in the AI writing tools landscape: it is a feedback engine built specifically for students who want to check their assignments against custom criteria before submission. Unlike general-purpose proofreaders or essay generators, this tool explicitly refuses to write or rewrite content. Instead, it uses OpenAI’s GPT models to analyze a student’s draft against the marking criteria they provide, then returns structured guidance on where the assignment meets or misses expectations. The core value proposition is not correction but diagnosis—pointing out, for example, that a critical evaluation section is underdeveloped or that an argument lacks supporting evidence. This positioning is deliberate and, for the right user, genuinely useful. The tool’s standout strength is its personalization: by letting students input their own criteria (e.g., rubric items or assignment briefs), the feedback is tailored to the specific expectations of a given task, not generic style advice. The free tier—10,000 words lifetime with GPT-4o mini—is generous enough for occasional use, such as a high school student checking a term paper or a first-year university student testing the waters. The paid tier at £3.99 per month unlocks 250,000 words, GPT-4o, downloadable feedback, and a wordback feature that preserves the original formatting. For students submitting multiple assignments per month, the paid plan offers practical continuity. However, the tool has clear limitations. It is not a writing assistant in the broad sense; it cannot help with brainstorming, outlining, or drafting. Its feedback is only as good as the criteria provided, and students who are unsure what their instructor expects may struggle to frame effective criteria. The tool also processes data through OpenAI’s APIs, and while the company states that API data is not used for training, privacy-conscious users should review the terms. The feedback itself, being AI-generated, can sometimes be generic or miss nuance—especially for highly specialized or creative assignments. In terms of workflow, Mark This For Me fits best as a pre-submission sanity check. A student writes their assignment, then uploads it along with the rubric or assignment brief. The tool returns feedback within seconds, highlighting gaps in argumentation, alignment with criteria, and opportunities for deeper analysis. This is not a substitute for a human tutor or professor, but it can help students who struggle to interpret vague criteria or who want a second opinion before the final draft. The tool also positions itself as a safeguard against academic integrity concerns, since it does not generate answers—only guidance. The FAQ emphasizes that the feedback is designed to prompt critical thinking, not to provide ready-made solutions. For students who are anxious about using AI in their work, this distinction matters. The ideal user is a conscientious student who wants to improve their writing without crossing ethical lines. High school students with occasional essays may find the free tier sufficient, while university students juggling multiple assignments across different subjects will benefit more from the paid plan. The tool is less suited for students who need help with grammar or style, or for those who want a fully automated grading system. Ultimately, Mark This For Me is a focused, honest tool that does one thing and does it reasonably well. It does not promise to make writing easy; it promises to make feedback accessible. For students who are willing to invest the effort to provide clear criteria and interpret the AI’s suggestions, it can be a valuable part of their study toolkit.
