Paperpal offers a robust free plan that provides 200 grammar suggestions per month and 150 Paperpal Copilot uses monthly, making it one of the best free AI tools for research paper writing. The free tier includes access to core academic writing features, limited plagiarism checking, and submission readiness checks. Unlike generic AI writing tools, Paperpal is specifically trained on millions of scholarly articles, ensuring that suggestions follow academic conventions and discipline-specific language.

Paperpal's AI Copilot and generative AI features assist researchers in creating concise research paper summaries and abstracts by analyzing the full manuscript content. The tool uses context-aware AI trained on scholarly articles to generate academically appropriate summaries that capture key findings, methodology, and conclusions. Researchers can use the rewrite and paraphrase features to refine abstracts, ensuring they meet journal requirements and word limits. The AI research finder also helps verify that summary statements are backed by citations from the 250M+ article database, maintaining academic integrity throughout the summarization process.

While Paperpal's free plan provides valuable writing assistance with 150 Copilot uses and 200 grammar suggestions monthly, writing a complete research paper typically requires more extensive AI support available in the Prime plans. The free tier helps with ideation, grammar checking, and basic writing assistance, but unlimited generative AI capabilities for drafting, rewriting, and expanding sections are reserved for Prime subscribers at $25 per month or $139 annually. Paperpal is designed as a writing assistant rather than a replacement for researcher expertise, helping accelerate the writing process by 2x while maintaining academic quality and originality.
