This Paperpal alternative is for authors whose draft needs more than better English: stronger evidence, checked references and a review of the argument. Paperpal is an excellent academic language editor in Word and Overleaf. AI for Research finds and filters papers, checks claims and references, scores your draft and writes with live citations.
What Paperpal is best at
Paperpal is an academic writing assistant focused on language. It gives grammar and tone suggestions it says are trained on millions of scholarly edits, and it aims at the language and formatting standards of 1,500+ journals [1]. It works where you already write: a Microsoft Word add-in, Google Docs, a Chrome extension and Overleaf [1]. Before submission it runs 30+ pre-submission checks and a similarity check against 99B+ sources, and it adds research help: access to 250M+ articles, chat with PDFs and citations in 10,000+ styles [1]. It says your files stay private and are never used to train AI [1]. For a researcher writing in English as a second language who drafts in Word, Paperpal is one of the most practical tools available. Its free plan includes a monthly allowance of language suggestions [2].
Where AI for Research differs
Paperpal improves how your text reads. AI for Research works on what your text says and what it rests on.
- Evidence before you write. Deep Research answers a question from scholarly sources with a consensus line: Summary 1 credit, Deep 15 credits for a 2,500 to 4,000-word report. Find Papers filters by study type, year, journal quality tier and peer review, and leaves out retractions (0 credits).
- A review of the argument. The Reviewer scores a thesis, proposal or manuscript on each criterion out of 10, at undergraduate, honours, master's or PhD level, with comments that quote the passage and suggest a fix. Standard costs 10 credits per 10,000 words; High quality (Pro) 30.
- Claims and references checked. Claim Check labels up to 10 claims from a paragraph as supported, partly supported, not supported or no evidence, with the papers (2 credits). Citation check confirms each reference exists in Crossref or OpenAlex and flags retractions, corrections, expressions of concern, preprints and wrong years or authors (0 credits).
- Language tools too. The editor proofreads the whole document for grammar, word choice and repetition as tracked changes, and Writing Studio's Improve document shows word-level before and after for each paragraph (1 credit per 2,000 words).
- Drafts with live citations. Open a research result in the editor and draft with cited autocomplete in any of 10,000+ styles.

How to use Paperpal and AI for Research together
- Review the substance first. Upload your manuscript to the Reviewer, choose Manuscript and your level, and run a Standard review. Fix the passages it quotes.
- Check the evidence. Run Claim Check on the paragraphs your argument rests on. Where a claim comes back as no evidence, search Find Papers with study-type filters and add a source, or soften the claim.
- Check the references. Paste the reference list into Citation check and fix every flag.
- Polish the language. Export to Word and run Paperpal's language and pre-submission checks inside Word.
- Submit. Last, run your journal's or institution's similarity check.
A worked example
Example (invented, for illustration). A postdoc preparing a 7,500-word manuscript on soil carbon runs the Reviewer at PhD level: 10 credits. The discussion scores 5 out of 10; one comment quotes a sentence claiming that no-till farming "consistently increases" soil carbon. Claim Check (2 credits) labels it partly supported: the papers it finds report mixed results by depth. She rewrites the sentence and adds two field studies found with Find Papers. Citation check (0 credits) flags one reference that has a published correction. She then exports to Word and polishes the English in Paperpal. Total in AI for Research: 12 credits.
What AI for Research does not do
- No plagiarism or similarity check. Use Paperpal's or your institution's.
- No Word add-in, Google Docs extension or Overleaf plugin. You upload, edit in the browser and export.
- No translation tool.
- No journal-specific formatting checks. The Reviewer looks at content and structure, not a journal's author guidelines.
- No AI-detector scores. The AI writing checker shows stock phrases and patterns only.
What it costs
Free: 45 credits a month and the Reviewer preview. Plus: $12 a month or $96 a year for 750 credits. Pro: $29 a month or $228 a year for 1,500 credits and High quality reviews. Reviewer Standard 10 credits and High quality 30, per 10,000 words; Claim Check 2; Citation check 0. See pricing.
