    Field-aware routing

    Smarter search because every field needs different sources

    Praxeli reads your query context and routes to the most relevant source groups — not a one-size-fits-all index.

    Smart Features That Set Us Apart

    System intelligence — each capability improves source quality, speed, or citation confidence.

    Field-Based Routing

    What it does
    Sends your query to the most relevant academic source groups.
    Why it matters
    Better source quality by discipline — not one-size-fits-all search.
    Result
    More relevant results, faster.

    Citation Prioritization

    What it does
    Highly cited, influential papers surface first in results.
    Why it matters
    Academic impact matters more than keyword density alone.
    Result
    Authoritative sources rise to the top.

    Free PDF Discovery

    What it does
    Surfaces free, legal full-text access where available across sources.
    Why it matters
    Paywalls slow research — open access links save time and cost.
    Result
    30M+ PDFs discoverable in workflow.

    Source-Grounded Citation Workflow

    What it does
    Citations trace to indexed academic sources with verification support.
    Why it matters
    Designed to reduce fabricated references in academic drafts.
    Result
    More traceable, defensible citations.

    Parallel Source Fetching

    What it does
    Queries all 14 sources simultaneously in under 3 seconds.
    Why it matters
    Sequential search wastes time when coverage should be parallel.
    Result
    Broader coverage without waiting on one index.

    Smart Deduplication

    What it does
    Detects the same paper across multiple sources and merges duplicates.
    Why it matters
    Duplicate hits create noise and slow literature review.
    Result
    Clean, organized result sets.

    The difference

    Traditional Tools vs Praxeli

    Same research goal — fundamentally different infrastructure underneath.

    • Generic, non-field-specific results
    • Slow research workflow
    • Limited to 50M–200M papers
    • Miss highly cited papers

    Praxeli

    Recommended
    • Search 14 sources simultaneously
    • Automatic deduplication
    • Free PDF discovery built-in
    • Field-based routing by discipline
    • Citation prioritization by impact
