Crystal (Crystal Knows) platform help — personality prediction for sales communication: predicts a prospect's DISC type (plus Big Five/OCEAN, Enneagram, 16Personalities) from a LinkedIn URL, email, or text sample and returns emailing, selling, and rapport tips. Chrome extension, HubSpot/Salesforce sync, a Personality API (connect.crystalknows.com Profile + Analysis endpoints), and an MCP server for Claude/Cursor. Use when a prospect's DISC profile looks wrong or low-confidence, the Chrome extension preview limit ran out, HubSpot deal sync isn't showing personality data, you're wiring the Profile or Analysis API into a CRM, the API returns 401 or 402, setting up the Crystal MCP server in Claude, or worried about GDPR consent for personality profiling. Do NOT use for choosing between personality-selling tools like Humantic or Humanlinker (use /sales-personality-selling) or general contact enrichment across providers (use /sales-enrich).
