PERRLA vs Grammarly: Which Is Better for Academic Writing?

What does Grammarly actually do?

Grammarly is a writing assistant. Its core job is the quality of your sentences - grammar, spelling, clarity, tone, and word choice. It's good at that.

‍
Grammarly does offer citation-related features, including tools that can help users create citations. However, Grammarly's primary focus is writing assistance, not formatting entire papers to APA, MLA, or Turabian requirements.

What does PERRLA do that Grammarly doesn't?

PERRLA is built around the paper itself, including the citations and formatting requirements that fall outside Grammarly's primary focus.

‍
• Building accurate references in APA, MLA, and Turabian
• Formatting the whole document to the style guide (title page, headings, spacing, reference list)
• Keeping in-text citations and the reference list in sync as you write

‍

PERRLA's citation engine is built from the APA 7 manual and verified against it.

Why a paper can look perfect and still lose points

This is where students often run into trouble: a paper can read perfectly clean and still lose points because the formatting and references don't match what the style guide requires. Polished sentences and correctly formatted APA are two different jobs.

‍
A simple way to think about it is this: Grammarly focuses on the writing itself. PERRLA focuses on the formatting and citations around that writing..

Do you have to choose one?

No. Many students use Grammarly and PERRLA together. Grammarly helps improve grammar, spelling, clarity, and readability.

‍
PERRLA helps ensure citations and formatting follow APA, MLA, or Turabian requirements. Because they're solving different problems, many students find they work well side by side.

Does PERRLA change your writing?

No. PERRLA formats what you've already written. It doesn't rewrite sentences, adjust tone, or alter your voice. That's intentional.

‍
Grammarly is designed to help improve how your writing reads. PERRLA is designed to help ensure the formatting and citations are correct while keeping the student's writing unchanged.

‍
PERRLA also makes only standard spelling suggestions, deliberately, so it doesn't alter a student's voice. A tool built to rewrite and reword sentences changes how the writing sounds. PERRLA leaves the student's words alone. For students and faculty, that's an important distinction.

Where Grammarly wins

We're not going to pretend PERRLA is better at everything, because it isn't.

‍
Grammarly does several things better than PERRLA:
‍

• Grammar correction
• Clarity suggestions
• Tone feedback
• Sentence-level editing
• General writing assistance

‍
If your biggest concern is improving how your writing reads, Grammarly is built for that.

A Note on AI

‍
The one disclosed place PERRLA uses an LLM is to pull bibliographic details such as author, title, and publication date from a PDF. Those details are then verified against third-party databases such as CrossRef and ISBNdb.

As AI tools become more common in academic writing, it's worth understanding the difference between generating citations and formatting them. Asking a chatbot to generate citations can sometimes produce references that look correct but contain inaccurate or fabricated information.

‍
Grammarly and other AI-powered writing tools can also suggest reworded sentences, revised phrasing, and tone adjustments. For some students and instructors, that raises questions about how much of the final wording comes from the student versus the software.

‍
PERRLA serves a different role. Its citation engine is built from the APA 7 manual, and it never generates or alters the content of your paper.

Grammarly Authorship vs. PERRLA's Writing Timeline

‍
Both tools give students a way to show how a paper was written. They go about it differently.

‍
Grammarly Authorship records your writing as it happens. It labels text as typed, pasted, or AI-generated, names the sources pasted text came from, and can replay how the document was written. Students choose whether to share the report.

‍
PERRLA's Writing Timeline is built from the saves PERRLA already makes. It shows your writing sessions, how long you worked, how the paper grew, and the sources you added. It never includes the paper's text, never labels anything as AI or human, and never shows dates or times of day. At schools that use it, a link on the title page lets faculty open the timeline, and the student can take that link off.

‍
Grammarly Authorship works in more places, including Google Docs. The Writing Timeline covers writing done in PERRLA Online and the PERRLA add-in for Word.
