Tree-Guided Hybrid Search
Traditional RAG systems split documents into flat chunks, losing structure and context. Nia invented a different approach:Document Trees
PDFs are parsed into hierarchical structures — sections, subsections, figures, tables — preserving the document’s logical organization.
Section-Level Indexing
Each section is indexed with its position in the hierarchy, enabling precise retrieval that knows where information lives.
Hybrid Signals
Combines vector embeddings with non-vector signals (headers, page numbers, cross-references) for high recall with minimal context bloat.
Hierarchical Traversal
Agents traverse documents as trees instead of scanning flat chunks, finding relevant sections faster and more accurately.
Why it matters: High recall across large PDF corpora without stuffing context windows with irrelevant chunks. Read the technical deep-dive →
Interactive Papers Playground
Experience PDFs like never before at app.trynia.ai/playground/papers:PDF Viewer
View documents directly in the browser with a full-featured PDF viewer. Resizable panes let you read and chat side-by-side.
Document Tree
Navigate using an intelligent document tree. Jump to specific sections, figures, or equations instantly.
Session History
Your conversations are saved. Return anytime to continue where you left off, or review past discussions.
LaTeX Rendering
Full LaTeX support for mathematical expressions. Complex equations render beautifully in chat responses.
Document Agent & Data Extraction
Once a PDF is indexed, you can go beyond search with two powerful capabilities:Document Agent
Deploy an autonomous AI agent into your PDF. It plans its own research strategy, uses tools to search, read, and navigate — then delivers cited answers or structured output via JSON schemas.
Data Extraction
Extract structured records from PDFs using JSON schemas. Pull tables, financial data, specifications, and more into clean structured formats.
How It Works
Index a PDF
Provide an arXiv URL, paper ID, or upload directly:
- “Index https://arxiv.org/abs/2401.12345”
- “Index this SEC filing”
Tree Extraction
Nia parses the PDF structure — sections, headers, figures, tables — building a navigable document tree.
Use Cases
Research Papers
Index arXiv papers for literature reviews. Search across dozens of papers at once, compare methodologies, understand dense sections.
SEC Filings
Navigate 10-Ks, 10-Qs, and proxy statements. Find specific disclosures, compare across years, extract financial data.
Legal Documents
Index contracts, briefs, and regulations. Search for specific clauses, understand obligations, compare versions.
Technical Manuals
Index product documentation, API specs, or internal wikis. Get precise answers with section references.
