Comparative Analysis of SciSpace vs Inline AI
1. Differences in Functionality
SciSpace: Strong in searching, translating, and summarizing papers from English-speaking regions
SciSpace is connected to a global paper database, notably excelling in searching, quickly summarizing, and extracting literature reviews from English-speaking regions.
Its intuitive interface allows you to search countless related papers and quickly grasp summarized insights with just a keyword input. Additionally, the ability to simplify paper contents into plain English and the literature comparison function greatly aid in the early stages of research.
Inline AI: Facilitates extensive data input, extraction, citation, and paper creation and completion
Inline AI functions as a powerful tool when you actually need to 'write the paper,' going beyond simply reading and organizing papers.
By inserting dozens to hundreds of downloaded paper PDFs, summaries, reports into the AI, you can find the desired content or citation accurately, even if you just ask "Where is this information?". It extracts to the exact document and page, which is very practical for writing academic papers that require precise citations.
Additionally, when facing deadlines for dissertations, journal submissions, and reports, Inline AI supports comprehensive writing tasks by recommending structure, searching for citation sources, and significantly shortening the actual writing process.
2. Differences in Prompt Use Ease
SciSpace has the inconvenience of needing to input English prompts, especially in more professional academic fields.
While simple Korean phrases like "What's the conclusion of this paper?" are recognized, it often fails with specialized academic terminologies based on expertise in Korean, leading to inaccurate answers.
There is a significant difference in the quality, contextual understanding, and accuracy of responses between Korean and English prompts.
Inline AI, based on the top-tier reasoning model 'Claude Sonnet 4,' finely tuned for domestic researchers, understands and performs even when you input in Korean, akin to speaking with an academic peer.
You won't face difficulties due to prompt input and answer quality.
Being an AI trained in a wide range of specialized knowledge, it can accurately translate even complex academic content by simply inputting, "Translate this paper."
When you input "Summarize this paper," it provides structured translations while maintaining the original composition.
3. Security and Privacy Issues
SciSpace is cloud-based, meaning papers uploaded and content input by users are processed on external servers. It may pose usage restrictions in projects where security policies are tightly integrated, such as government projects, semiconductor, pharmaceutical, defense fields, due to concerns of data leakage.
Inline AI operates as a desktop application, ensuring that document files being edited do not transmit externally, alleviating the concern of sensitive information and privacy leaks.
This point can be crucial for domestic researchers handling government projects, sensitive papers, and tasks prone to external leaks.

SciSpace vs Inline AI - Conclusion
SciSpace is a great tool for searching and translating English papers.
However, its use is limited as it presupposes proficient use of English prompts, and the input data is transmitted to an external cloud.
Inline AI is developed specifically for domestic researchers, with advantages of being Korean-based, local resource-based, and superior in security.
Accordingly, it can be a practical choice for researchers in Korea enrolled in master's and doctoral programs or those affiliated with private companies.
For Korean researchers burdened with paper writing and paperwork like government project reports and various reports, Inline AI can save a lot of time as a personal assistant.
It supports as an 'academic partner AI' throughout research activities such as paper search, translation, summarization, storage, extraction, citation, paper drafting, and editing.
