DISC doesn't tend to offer deeper, more emotional insights.

How to get someone’s personality type
Learning more about other people through personality data can help you improve relationships, make sales, reach a new audience, resolve conflict, and more. Taking the time to invest in people and communicate with someone in a way they want is important to making both of your lives easier and more enjoyable.
There are a few common ways to find someone’s personality type:
Free Personality Test
Assessments: These can be made up of multiple choice, word ranking, or behavior rating questions. While this is generally the most accurate way to identify a personality type, it requires active participation from the person. If you are trying to get to know more about a stranger, or even a friend or family member who is simply turned off by the idea of completing a questionnaire, this is likely not possible.
Personality AI: This is the use of machine learning and artificial intelligence to predict someone’s personality from their writing style, or attributes about them. This new technology analyzes publicly available information on websites like LinkedIn to predict someone’s personality, using artificial intelligence and machine learning. We built our product, Crystal, to harness Personality AI and enable anyone to identify personalities online to improve their communication and build stronger relationships, all based on the core principle of empathy.

Create your own profile
Chrome Extension

Crystal’s Chrome Extension generates a predicted personality profile by analyzing someone’s LinkedIn page or CRM record in tools like Salesforce. This will help you better understand how another person likes to communicate (even if you don’t know them) and offer suggestions for how to format and phrase your emails to them. Whether you need to build personal rapport, request meeting times, negotiate, collaborate, or just make an effective sales pitch, you can start guessing less and sending emails with more confidence.

Conversation Coach

Every call, meeting, and discussion you encounter is a unique situation, and you don’t always have much time to prepare. To help with this problem, you can use Crystal to get scenario-specific advice for communicating with your colleagues, clients, and potential customers. Crystal can help you resolve conflicts, collaborate on a project, brainstorm ideas, deliver difficult news, and more. Rather than flying blind, it’s like having an expert sitting next to you, telling you the best way to begin the conversation, frame your message, and call others to action.

Rather than needing to go directly to Crystal’s website or mobile app, you can view personality profiles for co-workers and get communication guidance for everyday situations without ever leaving a conversation in Slack.
