Grammarly is one of the most widely used writing tools among UK students. SafeGrade is built specifically for the UK university essay context. They overlap in some areas and diverge significantly in others — and understanding the difference will help you use the right tool at the right point in your writing process.
What Grammarly does
Grammarly is a writing assistant. Its core function is grammar, spelling, punctuation, and style correction — it identifies errors in your text and suggests fixes in real time as you write. The premium version adds more advanced suggestions: clarity, engagement, delivery, and tone adjustments.
It also has an AI writing feature (Grammarly GO) that can help rephrase sentences, generate text, or summarise documents. And it includes a plagiarism checker in the premium tier that compares your text against web sources.
What Grammarly doesn't do: it doesn't check Harvard or APA referencing, it doesn't estimate your UK grade band, it doesn't analyse AI-risk patterns the way Turnitin does, and it has no concept of UK academic writing conventions or subject-specific requirements.
What SafeGrade does
SafeGrade is a pre-submission checker built specifically for UK university students. Rather than correcting grammar as you write, it analyses your finished essay across dimensions that matter for submission: AI-risk patterns, writing quality, referencing accuracy, and grade estimation.
It also has grammar and spell checking — but that's one of several tools, not the primary function. The primary function is answering: "Is this essay ready to submit, and what might get flagged?"

The problem with using Grammarly on academic essays
Grammarly is optimised for general English clarity — not for UK academic writing conventions. This creates a few specific problems:
- It flags correct academic constructions as errors. Passive voice ("it was argued that"), formal hedging ("it could be contended"), and complex sentence structures are all standard in academic writing. Grammarly often flags these and suggests simpler alternatives that would actually lower your academic register.
- Its AI suggestions can introduce AI-sounding phrasing. Using Grammarly GO or accepting its style suggestions can produce text that reads more uniformly and formally — closer to AI writing patterns — which could raise your Turnitin AI detection score.
- It doesn't know about Harvard referencing. Grammarly will happily let you submit with mismatched citations, orphaned references, and formatting errors. These are among the most common reasons students lose marks.
- It doesn't know what's happening in your subject. A criminology essay and a biochemistry lab report require completely different writing conventions. Grammarly applies general English rules to both.
There's ongoing discussion among students about whether using Grammarly's suggestions raises AI detection scores. The honest answer is: it depends on how heavily you use it. Accepting suggestions in bulk can reduce the natural variation in your writing. Using it selectively for clear errors is generally fine.
The verdict
Many students use both — Grammarly while drafting for grammar, SafeGrade before submitting for everything else. They're not competing for the same job. If you're already using Grammarly and happy with it, SafeGrade handles the gaps it leaves.
doesn't cover.
