Key Benefits of Paperpal
Here is what makes Paperpal worth a look:
- Academic focus: Every suggestion is tuned for academic text. It protects your formal writing style instead of casualising it.

Feature Comparison
Ready for a closer look at Paperpal vs Grammarly? We compare ten areas below, from grammar checking to price. Each one tells you which tool fits which job.
| Feature | Paperpal | Grammarly |
|---|---|---|
| Starting Price | $19/month | $12/month |
| Free Plan | ✅ 200 credits | ✅ No expiry |
| Academic Training Data | ✅ | ❌ |
| Edits Per Document | 392 average | 1.5 per sentence |
| Academic Translation | ✅ 25+ languages | ❌ |
| Plagiarism Checker | ✅ | ✅ |
| Tone Adjustment | Academic only | ✅ Full range |
| Word & Google Docs | Word add in | ✅ Both |
| Best For | Research papers | Everyday writing tasks |
1. Grammar Checking and Sentence Structure
Paperpal: Grammar checking runs against academic conventions rather than general English. It breaks long sentences apart while keeping the sentence structure a journal expects. It also flags technical inconsistency, such as a term spelled two ways across a manuscript.
Grammarly: The grammar engine covers a broader error set, from comma splices to dangling modifiers. It catches more error types overall. On academic text it sometimes simplifies a clause that already makes sense.
2. Paraphrasing and Word Choice
Paperpal: Rewrites aim for precision in academic phrasing. Word choice shifts toward discipline-standard terms, not simpler synonyms. Extensive mode will untangle complicated words while holding the formal tone.
Grammarly: The paraphrasing tool is optimised for casual writing styles and readability. It trims wordy phrases well. For a thesis paragraph, it can flatten your voice toward everyday language.
3. AI Writing Assistant
Paperpal: The AI writing assistant drafts abstracts, outlines, and section summaries from your notes. It is designed specifically for research papers. Ask it for ideas on framing a discussion section and the output already sounds academic.
Grammarly: Its generative ai tool writes emails, replies, and outlines from a short prompt. The range of writing tasks it covers is wider. The default register is business casual, so academics end up editing it back up.
4. Plagiarism Checking
Paperpal: Plagiarism detection is tuned for academic text and journal submission. A plagiarism check costs credits from your monthly allowance. Run it once your manuscript is close to final.
Grammarly: The plagiarism checker sits inside the same editor you already use. Plagiarism checking covers web sources and academic databases. It is convenient, though the report is lighter on citation context.
⚠️ Warning: Neither plagiarism check replaces Turnitin. Your institution may still run its own scan.
5. AI Detection
Paperpal: The AI detector scores how machine-written a passage reads. That matters when a journal asks you to declare ai tools used. It reports on the section, not just the whole file.
Grammarly: Grammarly pairs its detector with a humanizer that rewrites flagged passages. Both writing assistants report a percentage score. Grammarly’s version is aimed at general writers rather than researchers.
The humanizer is a separate tool inside the same dashboard.
6. Citations and References
Paperpal: The citation generator formats references in the style your journal wants. Reference searching helps during a literature review. That saves a researcher real time at the start of the writing process.
Grammarly: Grammarly ships both a citation generator and a citation finder. The finder suggests sources for claims you have already written. Coverage is broad but shallower on niche academic databases.
The citation finder runs as its own tool in the web app.
7. Academic Tone vs Readability
Paperpal: Paperpal defends academic tone above all else. It pushes drafts toward a more formal writing style, never away from it. For a journal submission that is exactly the behaviour you want.
Grammarly: Tone suggestions let you dial a piece formal, friendly, or direct. Readability suggestions target sentence length and plain wording. This is the primary difference between the two products in daily use.
8. Proofreading and Paper Checking
Paperpal: The paper checker reviews structure, language, and journal-readiness in one pass. It tells you whether sections are missing before you submit. Students use it as a final gate on a dissertation chapter.
Grammarly: Proofreading covers spelling, punctuation, and consistency across any document type. An improved article usually needs fewer manual passes afterwards. Structural feedback for a thesis is thinner than Paperpal’s.
9. Translation and Source Reading
Paperpal: Write in your native language and Paperpal converts it into academic English. This academic translation covers over 25 languages and beats Google Translate on technical material. Chat PDF then gives you a detailed summary of any source you upload.
Grammarly: There is no translation layer for writers whose first language is not English. Instead you get a free essay and paper checker plus extra utilities. Useful, but not a substitute for drafting in your own language.
10. Pricing & Cost
Here is how the plans line up side by side.
| Plan | Paperpal | Grammarly |
|---|---|---|
| Free | $0 (200 credits) | $0 USD |
| Paid | Prime $19/month | Pro $12 USD |
| Team / Enterprise | ❌ | Contact Sales |
Paperpal: Prime costs $7 more per month than Grammarly Pro. What you buy is depth on one job rather than breadth. If you submit two papers a year, the extra spend pays for itself.
Grammarly: Pro is the cheaper monthly ticket and covers more document types. Its free version is also more generous over a full year. Enterprise pricing stays behind a sales conversation.

What Our Review Didn’t Cover
This comparison focused on individual students, researchers, and writers. We did not evaluate Grammarly’s Enterprise tier, shared style guides, or admin controls. We also did not test either tool on non-Latin scripts or on maths-heavy manuscripts. If you manage a department licence, your priorities will differ from what we covered here.

🏆 WINNER: PAPERPAL
Paperpal wins 4 out of 7 categories.
Best for: Research papers, journal manuscripts, dissertation chapters, and writers working outside their first language.
Grammarly and Paperpal are not really the same product. One is writing assistant software for everything you type. The other is academic writing assistant software with a narrow focus.
Grammarly is excellent if your week mixes emails, blog drafts, and reports. It catches more error types and costs less. For that reader, choose Grammarly and stop reading here.
But if your writing journey runs through journals, Paperpal is a better fit. Its features tailored to academics are the reason. That is why it takes our top spot.
