Pen Spirit AI Writing is an intelligent assistant focused on academic writing, providing end-to-end support for papers, de-duplication and plagiarism checks, and formatting and typesetting features, aimed at helping students and researchers efficiently produce high-quality academic content.
Pen Spirit AI Writing is an intelligent writing assistant focused on academic contexts, offering an all-in-one solution for writing, de-duplication and plagiarism checks, and formatting, primarily serving students and researchers.
It offers a free version and a membership model. The free version has usage limits on the number of uses and word count; advanced features such as long-form generation and advanced de-duplication require a membership (monthly, quarterly, yearly options).
It uses a semantic reorganization algorithm tailored to CNKI rules, promising to reduce similarity to a safe threshold within 2 minutes, and provides an AI-generated content trace-elimination feature to address AI content detection.
Primarily supports academic writing, such as theses, proposals, literature reviews, etc., while also covering over 200 writing scenarios including some professional reports, official documents, and new media copy.
The tool itself provides checking and de-duplication services, but the originality of generated content depends on user input and adjustments. It is recommended to use its de-duplication feature after generation or perform your own plagiarism check to ensure compliance.
Pen Spirit AI Writing emphasizes simplifying the academic writing process through templating and scenario-based design, suitable for users who need to follow fixed formats; tools like DeepSeek focus more on intelligent literature retrieval and in-depth analysis.
