knowledgelib.io — AI Knowledge Library

Structured, cited knowledge units built for AI agents. Pre-verified answers to high-friction questions with full source provenance, confidence scores, and freshness tracking. One knowledge unit replaces 5 web searches and 8,000 tokens of parsing.

Why

When AI agents need to answer complex questions, they run multiple web searches, fetch noisy pages, and spend thousands of tokens parsing and cross-referencing — often producing unreliable answers with no source trail. knowledgelib.io short-circuits this:

Without knowledgelib.ioWith knowledgelib.io
Token cost3,000 - 8,000 tokens~600 - 1,800 tokens
Sources citedUsually none100% — every claim linked to a source
ConfidenceUnknownScored 0.0 - 1.0 per published methodology
Compute cost$0.50 - $5.00 per question$0.10 per query (API)
FreshnessUnknownVerified date + update schedule on every unit

How It Works

Each knowledge unit is a self-contained answer to one canonical question. Units use YAML frontmatter for machine-readable metadata and inline source citations for auditability.

For AI agents (via web search — zero setup)

Every knowledge unit has its own web page optimized for search engine indexing. When your agent searches the web, our pages rank for AI-style queries (factual, specific, including year and data type). The page body IS the markdown — no HTML parsing needed.

For AI agents (via API / MCP)

# Raw markdown unit
