Those notes appear in the “What Our Team Noticed” sections below.
By the end, you will know which one fits your writing process.
What is Paperpal?
Paperpal is an AI powered assistant built for academic writing.
It works on the web and as a word add in.
The add in covers Microsoft Word, Google Docs, and Overleaf.
Its models were trained on millions of published scholarly articles.
That training gives it real context sensitivity inside an academic context.
It reads your academic text and returns subject specific language suggestions.
Support spans over 1,300 subject areas, from physics to public health.
Here is a walkthrough of how the editor behaves in practice.

🏆 Winner: Paperpal
Built for research writing, not blog posts. Runs over 30 language and technical checks before you submit.
Paperpal Pricing
Paperpal keeps its plan list short. There are two tiers, and the free version is genuinely usable for light work.
| Plan | Price | Best For |
|---|---|---|
| Free | $0 | Students testing grammar checks |
| Prime | $19/month | Researchers needing unlimited language checks |
Pricing verified July 2026.
Free trial: No card needed. The free version gives you a limited number of suggestions each month, plus multiple free rounds of basic checks.
Money-back guarantee: Not published. Test the free tier first, then upgrade to Paperpal Prime when your limits run out.
📌 Note: Prime unlocks unlimited language corrections and unrestricted generative use. The free tier caps how often you can rerun checks on the same document.
⚠️ Pricing conflict flagged: Our research notes list Prime at $25/month and a $9–$19 range elsewhere. Our CSV records $19/month, which is what this table uses. Check the checkout page before you buy.
Key Benefits of Paperpal
Here is what makes Paperpal worth considering:
- Accurate language edits: Real time suggestions catch complex grammar errors as you write. Style corrections keep a formal tone throughout.
- Literature search: Plain English questions search over 250 million verified research articles. Answers are validated based on published literature.
- Citation generator: It produces references in over 10,000 styles, including APA, MLA, and Chicago. Changing references between journals takes seconds.
- Pre submission checks: Over 30 language and technical checks flag issues that cause desk rejections. You get a readiness report before you submit.
- Word count trimming: It cuts text to hit journal prescribed word counts. The meaning of your study highlights survives the trim.
- Privacy policy: The company states it never uses author data for training Paperpal’s ai models. Your drafts stay yours on Paperpal servers.
- Regional spelling: You choose American or British English before you write. Non English words and technical terms are left alone rather than flagged.

The short clip below walks through those benefits inside a live manuscript.
What Our Team Noticed
Our writer signed up for Paperpal and ran two draft chapters through the web version. Here is what stood out from that hands on time:
Paperpal Pros & Cons
✅ Pros
- Trained on academic texts, so suggestions match academic writing conventions
- Runs over 30 pre submission checks that reduce desk rejections
- Works inside Microsoft Word, Google Docs, and Overleaf
- Searches 250 million research articles and cites in 10,000 styles
- Free version lets you test grammar checks before paying
❌ Cons
- Narrow focus makes it a poor fit for marketing or blog work
- Free tier caps suggestions, so heavy users hit limits quickly
- Published pricing varies across sources, which makes budgeting harder
- No published refund window on the paid plan
What is CoWriter?
CoWriter is an ai writing tool aimed at long form content.
It runs on the web, with no desktop app required.
You give it a topic and it returns article ideas.
Then it builds an outline that resembles a long form SEO piece.
From there you can draft, rewrite, or change the voice.
The pitch is speed for people writing against tight deadlines.
Content marketers, web publishers, and small business owners are the core audience.
This overview shows the editor and the outline builder in action.

CoWriter
Turns a rough topic into an outline and a draft. Built for writers who need volume, not journal formatting.
CoWriter Pricing
CoWriter lists two paid plans and no permanent free tier. A limited trial lets you sample the tool first.
| Plan | Price | Best For |
|---|---|---|
| Pro | $20.00 | Solo writers drafting regularly |
| Premium | $385 | Publishers producing content at volume |
Pricing verified July 2026.
Free trial: Yes, with limited features. It is a sample of the toolkit rather than a free version you can live in.
Money-back guarantee: Not published. Use the trial to confirm output quality before you commit to Premium.
📌 Note: Both tiers are paid. Premium is the volume option, and it is the plan that unlocks early access to new features.
⚠️ Pricing conflict flagged: Our research notes say paid plans start at $19 per month. Our CSV records Pro at $20.00 and Premium at $385, and that is what the table shows. Confirm the billing period on the pricing page.
Key Benefits of CoWriter
Here is what CoWriter does well:
- Idea generation: It suggests angles when you are stuck on a topic. Writers use it to unstick ideas before drafting.
- Outline builder: Structures long pieces into headings and sections. The flow of the piece is decided before you write a page.
- Custom styles and tones: You set the voice once and drafts follow it. This helps self expression stay consistent across a series.
- Citation generator: Includes an IEEE citation generator for technical papers. That is unusual in a general drafting tool.
- Speed on deadline: A rough brief becomes a full draft in one sitting. Users report finishing outlines in half the time.
- Research paper generator: Produces structured drafts for students working through research writing assignments.

The next screen shows where those benefits sit inside the dashboard.

What Our Team Noticed
Our writer used CoWriter to draft a 1,500 word explainer from a one line brief. Here is what stood out:

CoWriter Pros & Cons
✅ Pros
- Outline builder handles long form structure well
- Idea generation helps writers past a blank page
- Custom writing styles keep tone consistent across a series
- Includes an IEEE citation generator for technical work
❌ Cons
- Output is often flagged as ai generated, so human editing is required
- No permanent free version, only a limited trial
- No Microsoft Word add in, so drafting happens on the web
- Premium pricing is a large jump from the Pro plan
Feature Comparison
These two products overlap less than the category label suggests. Paperpal is an editor and checker. CoWriter is a generator.
We walk through nine key features below, plus pricing. Watch this side by side comparisons clip first if you prefer video.
| Feature | Paperpal | CoWriter |
|---|---|---|
| Starting Price | $0 free / $19 per month | $20.00 Pro |
| Free Version | ✅ | ❌ (trial only) |
| Grammar Checks | ✅ | ❌ |
| Accurate Paraphrasing | ✅ | ✅ |
| AI Writing Drafts | ✅ | ✅ |
| Plagiarism Checker | ✅ | ❌ |
| AI Detection | ✅ | ✅ |
| Pre Submission Checks | ✅ | ❌ |
| Citation Generator | ✅ (10,000+ styles) | ✅ (IEEE) |
| Microsoft Word Add In | ✅ | ❌ |
| Best For | Academic writers polishing manuscripts | Writers drafting long form fast |
1. Grammar Checks and Precise Language Corrections
Paperpal: This is the core of the product. It handles language checks in two modes, essential and extensive, and is built for suggesting precise language corrections rather than surface fixes. Grammar suggestions arrive as instant feedback while you type, and it accurately detects complex grammar errors that lighter grammar checkers miss.

CoWriter: There is no dedicated grammar layer here. What you get is style corrections applied through custom tone settings, which shape voice more than mechanics. Word suggestions appear during drafting, but you should still run a separate checker before publishing.

2. Accurate Paraphrasing and Unclear Sentence Structures
Paperpal: The paraphraser rewrites sentences while keeping the original meaning. It will simplify unclear sentence structures without flattening technical terms, and it helps re organize paragraphs into better language structure. Contextual synonyms give you contextually relevant synonym suggestions instead of a generic thesaurus dump, and watching those swaps helps your vocabulary improve across drafts.

CoWriter: Rewriting happens through its essay writer rather than a standalone paraphraser. You can regenerate a section in a different style, which fixes tangled sentence structures by replacing them. That works for blog copy but gives you less control over a specific line.

3. AI Writing and Brainstorm Ideas
Paperpal: The “Write with AI” feature helps you create abstracts, outlines, and titles from prompts or uploaded notes. Paperpal Copilot works alongside your draft rather than replacing it, so ai writing stays assistive writing. This is the ai writing brainstorm ideas use case, scoped to research.
CoWriter: Generation is the main event. Give it a subject and it returns angles to brainstorm ideas around, then expands the one you pick. Creativity is the selling point, and it is faster than Paperpal at producing a full first draft.

4. Plagiarism Checks
Paperpal: A built in plagiarism scanner checks your manuscript against published literature. It is there to catch unintentional overlap, which matters when you quote heavily from research articles. For students and academic writers, this removes a separate subscription.

CoWriter: No plagiarism scanner is included. Since the tool writes new text rather than editing yours, the risk profile differs, but you still need an outside check before submitting anything graded.
⚠️ Warning: Neither tool guarantees a clean Turnitin report. Treat both scans as an early signal, not a final verdict from your institution.
5. AI Detection and Disclosure
Paperpal: It reports an ai detection score on your draft. It also ships AI Footprint and AI Disclosure templates so authors can report where generative ai was used. That transparency is aimed squarely at journals.
CoWriter: It markets AI Detection Proof output. Our research notes still describe its content as detectable as ai generated, so human oversight remains necessary. Read every paragraph before it goes out under your name.

6. Pre Submission Checks and Research Writing
Paperpal: The paper checker runs over 30 language and technical checks and returns a readiness report. It flags missing sections, formatting gaps, and text that exceeds journal prescribed word counts. Nothing else in this comparison targets academic writing excellence at that level of detail.

CoWriter: Its research paper generator produces a structured draft, which is a different job. There is no submission readiness report and no journal formatting layer. It helps you start research writing rather than finish it.

7. Citation Generator and Changing References
Paperpal: AI driven search finds relevant literature and formats citations in over 10,000 styles. Changing references from APA to MLA is a dropdown, not an afternoon. That breadth matters when one paper gets rejected and reformatted for a second journal.
CoWriter: The citation generator here is IEEE focused. If you write engineering or computer science papers, that single format covers most of your needs. Outside IEEE, the coverage thins out quickly.

8. Literature Search and Published Literature
Paperpal: Chat PDF lets you upload a paper and question it directly. You can also ask plain English questions across 250 million verified academic texts and get science backed answers. Answers point back to sources, so you can verify before you cite.

CoWriter: The outline builder organizes what you already know rather than searching a library. It is strong at structure and weak at sourcing. You bring the references; it arranges the argument.

9. Writing Process, Integrations, and Ease of Use
Paperpal: The ai writing assistant runs inside MS Word, Google Docs, and Overleaf, or in the browser. Web Paperpal gives you the same suggestions as the add in, so a Paperpal edited document stays consistent wherever you open it. Real time collaboration lets several authors work at once with tracked changes, and the edits land with close to human precision.
CoWriter: Everything happens in one browser workspace, including the ai script generator for video and audio work. There is no word add in, so you copy finished text into your document. Fewer moving parts means a shorter learning curve for beginners.

💡 Pro Tip: If your workflow already lives in Microsoft Word, an add in saves more time than any feature list. Copy and paste friction adds up across a long manuscript.
10. Pricing & Cost
Here are both plan lists side by side.
| Plan Type | Paperpal | CoWriter |
|---|---|---|
| Free | Free: $0 | ❌ Trial only |
| Entry paid | Prime: $19/month | Pro: $20.00 |
| Top tier | Prime: $19/month | Premium: $385 |
Paperpal: One paid tier keeps the decision easy. Prime removes the caps on language corrections and generative use, and the free version means you can validate the fit before spending anything.
CoWriter: Pro sits close to Paperpal Prime at $20.00. Premium at $385 is a different category of spend and only makes sense for publishers producing at volume with unlimited completion suggestions in daily use.
Different Scenarios
| If You Need… | Choose | Why |
|---|---|---|

Entry prices are almost identical at $19 and $20.00. The real gap is Paperpal’s free tier, which lets students start without a card.
🔌 Your Tech Stack
Paperpal aligns with Word, Docs, and Overleaf through add ins. CoWriter stays on the web, so you paste results into whatever editor you use.
📝 Your Writing Style
If you write in an academic context, Paperpal’s instant language edits match the conventions you are graded on. If you write marketing copy, CoWriter’s tone controls fit better.
🎓 Your Experience Level
Newer writers often learn faster with Paperpal because it explains each fix and builds writing skills over time. CoWriter hands you output and leaves the teaching to you.
🆓 Free Trials and Demos
Run one real chapter through Paperpal’s free tier before paying. Use CoWriter’s limited trial on a topic you already know, so you can judge accuracy.
🛟 Support Options
Both rely on documentation and email rather than phone support. Paperpal publishes more onboarding material for students and teachers working through a first manuscript.

What Our Review Didn’t Cover
This comparison focused on individual writers and small research teams. We did not test institutional licensing, custom API access, or translation support at scale. Our notes reflect the July 2026 versions of both products, and feature sets move quickly in this category. If you manage a department or need accessibility features such as speech to text, your priorities will differ from what we covered here.
Final Verdict
| Category | Winner |
|---|---|
| 💰 Pricing | Paperpal |
| 🚀 Core Features | Paperpal |
| ✍️ Draft Generation | CoWriter |
| 🎯 Accuracy and Quality | Paperpal |
| 👶 Ease of Use | CoWriter |
| 🔌 Integrations | Paperpal |
| 🏆 Overall Winner | Paperpal |
🏆 WINNER: PAPERPAL
Paperpal wins 4 out of 6 categories, with a 4.1 rating against 3.8.
Best for: Thesis and journal manuscripts, multilingual researchers, anyone editing inside Microsoft Word
These are two different products wearing the same category label. Paperpal makes existing work publishable. CoWriter makes new work exist.
If your job is to improve clarity, fix spelling, and get better vocabulary into a manuscript, Paperpal is the stronger tool. Its focus on academic text is the whole reason it beats broader ai tools at this specific task.
CoWriter is a good pick for content teams shipping on deadline. It will not prepare a paper for peer review, and it does not claim to.
For most people searching this comparison, writing with Paperpal is the safer bet. The ai writing revolution has produced plenty of powerful ai tools, but they only help when they match the work in front of you.
