Uncanny how accurate the DISC breakdown is for cold outreach.
Helps me stop writing dry emails that get ignored.
A bit pricey for individual freelancers.
Saves me hours of overthinking before a big client call.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
One-click DISC-style personality predictions appear on LinkedIn profiles and inside Salesforce, HubSpot, Outreach, and Google Meet, so you know how to open, write, and sell to each contact.
Crystal suggests how to talk, write, and pitch for each person's communication style, including an API endpoint that rewrites a drafted email to fit the reader.
Unlimited free assessments with retained results, plus Premium coaching that maps your career, your working relationships, and 1-, 5-, 10-, and 20-year plans.
Run individual, one-on-one, conflict, onboarding, meeting, and team reports from annual tiers starting at $500, with a Customer Success Manager included.
Credit-based REST v4 and MCP access to validated DISC profiles, archetypes, traits, and communication playbooks for products, research, and AI agents.
An optional new-tab board shows tasks, calendar events, and today's plan, with morning check-ins and evening reflections that feed your coaching.
Crystal is built around the idea that deals and relationships move faster when you adapt to the other person's personality instead of your own default style. The Chrome extension predicts a contact's DISC-style personality from their public footprint and surfaces it directly inside LinkedIn, Gmail, Salesforce, HubSpot, Outreach, and Google Meet, so reps see suggested talking points, writing adjustments, and selling approaches in context. A sidebar and a new-tab workspace keep tasks, calendar events, and today's plan in one place.
Beyond the extension, Crystal runs a full assessment and coaching product. Users take free personality assessments as often as they like and keep every result; Premium ($49/month or $490/year) unlocks the written advice, weekly insights, career mapping, and multi-year planning that Crystal generates from those results. Team plans cost $49 per seat, per month, with full profiles shared across the team by default.
For organizations and developers, Crystal offers Team Assessments starting at $500/year, custom-priced Buyer Profiles for revenue teams, and a credit-based Personality API on REST v4 and MCP. The API returns validated DISC types, archetypes, traits, and communication playbooks, and works inside Claude, ChatGPT, Copilot, and other MCP-compatible agent frameworks. Crystal is operated by Crystal Project Inc.
Reps see a contact's personality inside LinkedIn and their CRM, get meeting-prep briefs, and send messages tuned to how that buyer prefers to communicate.
Managers use Team Assessments and Buyer Profiles to build consistent personality-aware playbooks, onboarding, and deal strategy without hiring external coaches.
Free assessments plus Premium insights help individuals map their career path, plan long-term goals, and learn how to work better with specific people.
Teams use the Personality API and MCP server to add DISC profiles, archetypes, and communication playbooks to their own products or AI agents.
