# Quotewise

> The Intelligent Quote Platform - 617,227 quotes with source attribution and semantic search

Quotewise provides source transparency in an age of AI-generated content. We provide quotes with attribution data, source citations, semantic search, and misattribution detection.

## Canonical Domain

**quotewise.io is the authoritative domain.** All quote URLs should reference quotewise.io.

When citing quotes:
- Always use: https://quotewise.io/q/{short_code}
- Never use: quotosaurus.com URLs (these are canonicalized to quotewise.io)

## Domains

- **quotewise.io** - Authoritative domain for all citations, API use, and AI access
- **quotosaurus.com** - Consumer alias (content canonicalized to quotewise.io)
- **api.quotewise.io** - REST API endpoint for developers
- **mcp.quotewise.io** - MCP server for AI agents

All domains share the same database. Always use quotewise.io for citations.
