Kai

Agent

One AI assistant across your chosen context.

A dedicated place to talk with the same AI available across Kai’s consumer apps. Understand your records, compare options, build a plan, or ask for supported actions such as recording a meal. Coordinate a larger goal using the product context and remembered preferences you permit.

Questions and insights · Plans and actions · Multi-step tasks · Memory you control

Messages

Your Kai conversations, in a dedicated app.

Your ordinary Kai direct and group conversations in a focused app. Share a quick Blip about your day, answer a Buzz question together, or send a live-camera Flash. Use Drops for temporary sharing and Capsules for memories you intentionally keep, with the original audience and access respected.

Spark

Intentional dating. One connection at a time.

A dating app for live introductions and one active match at a time. Meet through your Kai public profile while keeping dating preferences and compatibility private. Explore a connection in a separate Spark chat, then mutually choose Continue on Kai when you want to move into ordinary messaging.

Lift

Strength training, programs, and progress.

Plan strength and hypertrophy training, from a sustainable beginner routine to a periodized competitive season. Build programs manually or with Kai, use exercise and workout-template libraries, and follow guided sessions. Track completed work, personal records, volume, and intensity as your goals and equipment change.

Adaptive programs · Workout execution · Exercise libraries · Progress and personal records

Pace

Running, cardio, and endurance.

Build consistency or prepare for an event with running, cycling, walking, and other cardio. Plan your training, capture activities on phone and watch, and review detailed session history. Follow goals, personal records, and gear use, with calculators and wearable connections supporting the bigger picture.

Fuel

Nutrition, meal planning, and recipes.

Bring meal planning, food discovery, and intake tracking together. Find recipes and substitutions around your preferences, budget, ingredients, and time. Log with photos, barcodes, natural language, or saved choices, then review macros, micronutrients, hydration, and consistency while keeping estimates distinct from confirmed information.

Muse

Private cycle health and insights.

A private place for cycle-health tracking, whether or not you have a fitness goal. Record flow, symptoms, mood, and energy; review period history and calendar patterns; and see predictions with their uncertainty visible. Choose whether selected cycle context informs another part of Kai.

Ease

Recovery, rest, and sleep.

Understand sleep and recovery, build a wind-down routine, or simply take a quiet break. Bring device-sleep data and readiness context into view, explore breath work and restorative practices, and listen to meditations, sleep stories, soundscapes, or white, pink, and brown noise.

Sleep and recovery · Restorative routines · Stories and soundscapes · Favorites and listening progress

Moment

Private reflections, habits, and life records.

Keep a private record of your life through Posts, notes, progress photos, and meaningful milestones. Follow habits, personal commitments, sobriety or recovery milestones, and countdowns with reminders and trackers. Reflect on change over time without needing to publish it or make every day a perfect streak.

Store

Products for life as an athlete.

Planned

A planned home for Kai merchandise and performance products, personal gear inventory, and wishlists. Shopping assistance can use permitted activity context to compare options around what you own, your budget, and your intended use. You stay in control of the merchant, items, quantities, and price before purchasing.

Business

Tools for creators, coaches, and businesses.

A workspace for creators, coaches, trainers, teams, gyms, and brands serving athletes. Manage digital products, courses, programs, memberships, paid Groups, and voluntary support alongside coaching relationships and staff responsibilities. Each offer has its own price and access terms, separate from the athlete’s general Kai subscription.
