Suppr

What is Suppr super-powered literature?

Suppr Super Literature is an AI-based platform for document translation and academic research, developed by WildData. It integrates PubMed literature searches, translation of files in various formats, in-depth research, academic information, and developer interfaces under one account system.

Suppr is aimed particularly at users in the fields of medicine, life sciences, and those who need to read foreign-language research papers. Its search interface is based on PubMed, and it should not be considered a general literature platform that covers databases from all disciplines.

Main functions

• Search for PubMed articles using natural language in Chinese or English.
• Returns structured information such as title, abstract, author, journal, DOI, and PMID.
• Narrow down the results by criteria such as year, journal, impact factor, or author.
• Upload PDF, Word, Excel, PowerPoint, text, and web page files for translation.
• Maintain the original document’s main layout and structure during translation.
• Special optimization options are available for mathematical formulas in PDFs.
• In-depth research reports in both Chinese and English are prepared based on the research questions.
• Export the results of in-depth research as a Word document.
• Translate directly within the literature management process using the Zotero plugin.
• Use browser extensions, Windows or Mac clients, and WeChat mini-programs.
• Connect to external workflows through open APIs, MCP services, and Claude Code Skills.

Overview of product capabilities

Search PubMed in Chinese

Users can directly enter their research questions in Chinese; the platform converts these into queries suitable for searching and returns relevant medical literature. The results include information such as abstracts, authors’ institutions, journals, publication years, impact factors, citation counts, and links to the full articles.

• Describe diseases, interventions, outcomes, or research directions in natural language.
• Limit to recent years, specify authors, or specify journals.
• Use expert mode to obtain a more academic style of result presentation.
• Choose between an academic style and a popular science style for the presentation.
• Organize the literature evidence, research directions, and potential gaps in research.
• Establish a candidate list of documents for reporting, reviews, and interdisciplinary research.

Tutorial on literature search

1. Log in to Suppr and go to the literature search page.
2. Use one sentence to clarify the research subject, the intervention, and the time frame.
3. Choose expert mode or an expression style suitable for the readers.
4. Add conditions such as year, journal, author, or impact factor.
5. Run the search and read the result titles and summaries.
6. Open the details of the highly relevant papers to verify the DOI and PMID.
7. Return to the PubMed or journal page to verify the original record.

• Are the technical terms consistent throughout the text?
• Check whether the statistical values, units, signs, and confidence intervals are correct.
• Whether formulas, subscripts, and special symbols are lost.
• Are the chart titles, footnotes, and cross-references misaligned?
• Whether the author’s name, institution, DOI, and references have been mistranslated.
• Are there any errors in the paragraph order in two-column PDFs and scanned documents?

In-depth research

The in-depth research module is based on global scientific literature; users can enter a research question and have long reports in both Chinese and English generated. The publicly available examples cover fields such as medicine, public health, materials science, economics and finance, communication studies, digital humanities, education, and agriculture.

• Generate academic review and research progress reports.
• Identify trends, key studies, and potential opportunities.
• Compare drugs, technical approaches, or the competitive landscape in the industry.
• Prepare preliminary materials and a research framework for project application.
• Generate structured reports on interdisciplinary topics.
• Export the completed report as Word to continue editing it.

In-depth research on usage recommendations

• Specify the research scope, year, and key sub-questions in the question.
• It is necessary to distinguish between evidence, inference, and future predictions.
• For each key conclusion, verify it against the original paper.
• Supplement databases and gray literature that are not covered by the platform.
• Do not use the automatic report as a formal paper or as the result of a research project.
• Record the generation date and the process of manual modifications.

Zotero plugin

Privacy and the security of research data

To translate documents, it is necessary to upload the files to the Suppr service; the API and MCP also send the task data to the cloud. Users should read the current privacy policy, terms of service, and their organization’s data management policies before uploading.

• Remove names, medical record numbers, contact information, and any other data that can identify the patient.
• Do not upload unpublished patents, contracts, or documents subject to confidentiality agreements.
• Confirm that the content of the paper and database can be handed over to third parties for processing.
• Implement access control for API logs, task records, and download links.
• The fact that a file is saved for 365 days does not mean it must be retained until the end of that period.
• After the project is completed, remove the unnecessary translation files and keys.
• For highly sensitive studies, institution-approved local or proprietary protocols should be used preferentially.

GitHub and the open-source status

The official GitHub repository of WildDataX has made projects such as suppr-mcp, suppr-zotero-plugin, and suppr-skills available. The MCP and Skills repositories are licensed under the MIT license; installation instructions are also provided for the Zotero plugin. However, this does not mean that the Suppr cloud platform and its translation models can be considered fully open source.
