The AI coach that understands you.

30x more affordable than a professional coach

Coaching works. Most people never get it.

Coaching measurably helps people follow through, perform and cope. The catch has always been the price, and how few coaches there are.

Six months of coaching

$294with Crystal, vs$9,000+with a coach

Crystal is $49 a month, about $294 across those same six months. That is roughly 30x less than the low end of a coaching engagement, for coaching every day instead of once or twice a month. A good human coach is still better at the things a human is better at; the difference Crystal makes is between coaching every day and coaching never.

A coach, a chatbot, and Crystal

A human coach knows you but is rarely there. A chatbot is always there but does not know you. Crystal is both, for $49 a month.

Coaching cost is a typical six-month engagement of $9,000 to $25,000, spread monthly, from published 2026 executive coaching rate surveys. The 2025 ICF Global Coaching Study with PwC Research puts the global average one-hour session at $234. Generic AI spans the standard $20 consumer plan to the $200 top tier.

Ask a general model like ChatGPT anything and it answers well, but it meets you as a stranger: it has the message you just sent and little else. Crystal comes to every answer already knowing your personality, your goals, and everything you have worked on together.

About this comparison

“ChatGPT and Claude” is the average of the four OpenAI and Anthropic models tested: GPT-5.6 Terra, Claude Sonnet 4.6, Claude Opus 4.8 and GPT-4o. Against the single best of them, GPT-5.6 Terra, Crystal made about a third fewer mistakes. A mistake is a tricky spot the profile did not handle.

 than ChatGPT and Claude.

4x more likely to achieve your goals

A personality test gives you a label. Crystal gets you there.

A test tells you who you are, then leaves your goals in your head. Crystal writes them down with you and checks in every morning and night, which is the habit the research says works.

Goals kept in your head vs. goals written down and checked on

267 people were asked to set a goal. The ones who wrote it down and sent somebody a weekly progress report were twice as likely to reach it, or get more than halfway, as the ones who kept it in their head.

70/ 100

Wrote it down, reported weekly

35/ 100

Kept it in their head

4.3x

the odds of reaching the goal

The odds of reaching the goal were 70 to 30 for people who wrote it down and reported weekly, against 35 to 65 for people who kept it in their head. That is an odds ratio of about 4.3, which is where the 4x comes from.

A review of 138 experiments covering 19,951 people found the same thing, and found the effect is stronger when progress is reported to someone rather than kept private. That is the mechanic of Rhythm: a goal written down, and Crystal asking how it went.

About these numbers

Measured from Crystal's own data on September 24, 2026. Reviewers are colleagues and friends the user invites, so these ratings show how accurate results look to the people who know someone. They are not a scientific validity study, and reviews here mean a person reviewing a profile, not academic peer review. Rating is voluntary, so figures describe the people who chose to rate. The review program has run since April 2026. Staff, demo and test accounts are excluded, as are reviews of results that were later retaken.
