Sourcely

Accepts natural language queries or paper excerpts and uses semantic understanding to identify relevant academic sources. The system likely employs embedding-based retrieval against a curated academic database, matching query intent to citation metadata (authors, abstracts, keywords) rather than simple keyword matching. This enables finding sources even when exact terminology differs between the query and published papers.

Processes uploaded documents or pasted text to automatically identify citation contexts, extract referenced sources, and format them into standard citation styles (APA, MLA, Chicago, Harvard, etc.). The system likely uses NLP-based entity recognition to detect author names, publication years, and citation patterns, then maps these to full bibliographic records from academic databases.

Analyzes the full text of a user's draft or research document and recommends relevant academic sources that should be cited. The system builds a semantic representation of the document's key concepts, research questions, and claims, then queries academic databases to surface papers that address similar topics or provide supporting evidence. This goes beyond simple keyword matching by understanding the document's research narrative.

Accepts documents in multiple formats (PDF, DOCX, images, scanned papers) and converts them to machine-readable text using OCR for scanned documents and native parsing for digital formats. The system likely uses a pipeline combining format-specific parsers (PDF extraction libraries, DOCX DOM parsing) with optical character recognition (Tesseract or cloud-based OCR) for image-based inputs, preserving document structure where possible.

Converts bibliographic data between multiple citation formats (APA, MLA, Chicago, Harvard, IEEE, Vancouver, etc.) using format-specific templates and rules. The system maintains a structured representation of citation metadata (authors, title, publication date, DOI, etc.) and applies format-specific rules for ordering, punctuation, and abbreviation. This enables users to switch citation styles without re-entering source information.

Connects to external academic databases (CrossRef, PubMed, arXiv, Google Scholar, etc.) and metadata APIs to enrich citation records with complete bibliographic information. When a user provides partial citation data (e.g., author and title), the system queries these APIs to fetch missing fields (DOI, publication date, abstract, journal name) and validate the source. This enables automatic completion of incomplete citations.

Enables multiple users to maintain shared citation libraries or projects, with real-time synchronization of added sources, annotations, and formatting changes. The system likely uses a centralized database with access control (read/write permissions per user or team) and change tracking to support collaborative workflows. Users can tag, annotate, and organize shared sources without conflicts.

Analyzes a user's citations against their document content to identify quality issues: missing citations for claims, outdated sources, over-reliance on single authors, lack of diversity in source types, and potential citation errors. The system uses NLP to match claims in the text to cited sources, detects when citations are missing or weak, and recommends improvements. This goes beyond simple formatting validation to assess citation adequacy.
