Published on 2025/03/31 by Jasper Sutter
Introduction
Imagine writing a sales email and knowing exactly how the recipient prefers to be spoken to. Or preparing for an interview with insight into how the candidate communicates best. Crystal makes this possible by analyzing personality traits and offering AI-powered communication suggestions.
Built on the DISC personality framework, Crystal blends psychology and AI to enhance how we sell, hire, and collaborate.
What It Offers
Crystal analyzes public data, especially LinkedIn profiles, to generate personality predictions. Features include:
- DISC-style personality summaries
- Sales email guidance based on personality
- Hiring insights for recruiters and managers
- Chrome extension for inline LinkedIn insights
- Custom playbooks for teams and messaging strategies
You can think of it as Grammarly for emotional intelligence.

- Managers improving team communication and coaching

What Could Improve
- ❌ Predictions rely on public data, which may be thin or outdated
