Platform Philosophy
Copus and Are.na both reject algorithmic feeds in favor of human curation, but they approach it differently.
Copus positions itself as "The Internet Treasure Map" — a platform where curators recommend valuable internet resources with context and personal insights. Every curation includes the curator's recommendation explaining why the content matters.
Are.na uses a block-and-channel metaphor inspired by research workflows. Users save "blocks" (text, images, links) into "channels" that can be connected across users, creating a web of related ideas.
AI and Developer Integration
Copus leads significantly in AI integration. It offers an MCP server (npx copus-mcp-server) that works with Claude, Cursor, and other AI tools. All content is available as JSON-LD structured data, and the browser extension integrates directly with ChatGPT, Claude, Perplexity, and other AI chat interfaces.
Are.na has a REST API but lacks dedicated AI tooling, structured data exports, or AI chat integration.
