Nujan

Nujan: The AI Research Partner for Reading Papers, Mastering New Fields & Discovering Literature

Nujan is a full-lifecycle AI research workspace covering both early-stage discovery from scratch (starting with zero papers) and deep active reading. Start with only your research interests or Knowledge Profile (e.g., selecting Machine Learning, Oncology, Physics, or any custom topic) to receive broad-scale paper and topic recommendations across 250M+ works, get up to speed in any field from scratch with a First-Principles Research Coach, analyze favorite conferences, and read PDFs side-by-side with AI.

Five High-Level Researcher Workflows & Their Standout Features

1. Interactive Paper Reader & Smart Library

Read dense papers faster, unpack math and methodology right next to the PDF, and synthesize findings across your entire reading collection.

  • Dual-Pane Split PDF Reader & Grounded Chat: Keep the PDF on the left and AI research chat on the right, with every explanation grounded in clickable page numbers ([Page 4]).
  • Highlight-to-Ask & Line-Aligned Margin Notes: Highlight any equation, theorem, or passage to ask follow-up questions in place, or pin persistent margin notes (💬, 📝) anchored to the exact line of the PDF.
  • Interactive Crop & Ask (Visual Figure & Equation Breakdown): Draw a bounding box around any complex architecture diagram, table, or multi-line derivation on the PDF to get an instant visual and mathematical breakdown.
  • Authentic Extracted Figures Inline in Chat: When the assistant explains an architecture or empirical result, it embeds the actual cropped figures and tables from the paper directly inside the chat stream with a 1-click [Jump to Page] button.
  • Synchronized Citation Deep-Linking: Click any inline bibliography reference ([12]) to inspect the cited paper's metadata and abstract or import it into your library in one click.
  • Zotero-Style PDF Dark Mode: Toggle true-color dark mode on the PDF canvas that eliminates white page glare for late-night reading while preserving the original colors of figures, heatmaps, and plots.
  • Instant nujan.app/abs/... URL Swap & Web Blog Import: Replace arxiv.org with nujan.app in any paper URL (e.g., nujan.app/abs/2006.11239) to open it immediately in the Split Reader, or import technical engineering blogs (Anthropic, Lil'Log, Distill) as clean, citable PDFs.
  • 6-Part Structured Breakdown & Multi-Paper Synthesis: Every paper is auto-organized (Author - Year - Title) with a 6-part breakdown (TL;DR, ELI5, Core Contributions, Methodology, Empirical Results, Limitations), and you can select 2 to 4 papers for Side-by-Side Comparison Matrices or run Library-Wide RAG Chat across your entire bibliography.

2. Research Coach to Get Up to Speed with Any Field

Master unfamiliar research domains, bridge prerequisite gaps, and build deep intuition from first principles before or while diving into the literature.

  • Personalized 5-Step Socratic Curricula: Enter any research topic or select foundational papers from your library, and the Coach constructs a structured, step-by-step learning curriculum tailored to your background.
  • Prerequisite Gap Tracing & Intuition-First Explanations: Automatically identifies unstated foundational concepts and explains plain-English physical and geometric intuition before introducing formal mathematical notation.
  • Step-by-Step Mathematical Derivations & Architecture Diagrams: Unpacks every variable, loss function, and proof step in crisp KaTeX alongside interactive Mermaid architecture diagrams.
  • 2D Spatial Graph Chat (Branching Exploration): Switch seamlessly between [ Linear Chat | Graph Chat ] to branch off into side questions on specific sections or equations on an infinite 2D canvas without losing the main thread of your lesson.
  • Concept Flashcards & Standalone Tutorial Book Export: Automatically extracts key definitions and equations into reviewable flashcards, and exports any completed coaching session into a clean Markdown or interactive HTML textbook chapter.

3. Living Knowledge Profile & Personalized Recommendations (Start with Zero Papers)

Start from a blank slate with zero uploaded papers: select your academic fields and research interests (such as Machine Learning, Clinical Oncology, Computational Biology, or Econometrics) in your Knowledge Profile, and Nujan immediately discovers and recommends relevant papers and research topics from scratch.

  • Start with Only Your Research Interests or Bio (/profile): Fill out your Research Profile or select your fields and active keywords with zero papers in your library to immediately receive a curated reading list and topic roadmap across 250M+ scholarly works, while Nujan also auto-evolves your profile as you read papers and complete Coach sessions.
  • Interactive 2D Knowledge Map (/knowledge-map): Visualize your personal research brain as a force-directed graph connecting your Research Fields, Core Concepts, Papers, and Datasets, revealing blind spots and adjacent topics to study next.
  • Broad-Scale 3-Tier Paper & Topic Recommendation Engine (250M+ Works in /discovery): Continuously searches OpenAlex, arXiv, bioRxiv, medRxiv, Semantic Scholar, and OpenReview from scratch based on your Research Profile, plus anchors recommendations to your recent Research Coach topics and library papers (each with a "Why this matches your profile" rationale).
  • Twice-Weekly or Daily Literature Digests: Receive curated email digests (Tuesday/Friday or Daily) matched to your Knowledge Profile, with 1-click links to open any recommended paper directly in the Split Reader or Quick Focus summary view.

4. Analyzing Favorite Conferences & Research Frontiers

Track flagship conferences and benchmark datasets in your field directly from your selected research interests (no uploaded paper required) to see macro research trends and state-of-the-art shifts without drowning in thousands of accepted papers.

  • Favorite Conference Tracking (/conferences): Follow premier venues across domains (such as NeurIPS, ICML, ICLR, CVPR, ACL, EMNLP, KDD, MLSys, and domain-specific symposiums) filtered through your Research Profile with zero uploaded PDFs required.
  • Thematic Cluster Reports & Emerging Frontiers: Read AI-synthesized macro reports grouping accepted conference papers into core methodological themes, emerging research directions, and contrarian findings.
  • Automatic Benchmark & Dataset Extraction (/datasets): Browse benchmark datasets, evaluation metrics, and baseline comparisons across your field or extract them automatically from papers in your library.

5. Adversarial Peer-Review Sparring & Slide Deck Generation

Stress-test your own research ideas against simulated reviewers before submission, and turn papers or topics into presentation-ready slides in seconds.

  • Multi-Persona Adversarial Sparring Partner (/sparring): Critique a paper in your library or pitch your own draft methodology against 4 specialized reviewer personas (Critical Reviewer #2, Methodological Skeptic, Mathematical Purist, and Empirical Hawk) to catch experimental flaws and missing baselines early.
  • Sparring Decision Memory: Records key methodological critiques, concessions, and action items from each sparring session so your research plan improves iteratively.
  • 1-Click Journal Club & Lab Presentation Generator (/slides): Turn any single paper, multi-paper collection, or Research Coach curriculum into a structured slide deck with speaker notes, and export directly to Live Interactive HTML (Reveal.js), LaTeX Beamer (.tex), Marp Markdown, or PDF.
