The new age of coaching, for coaches and teams
Matter reads every athlete’s training, sleep, HRV, check-ins and nutrition, flags who needs a decision, and drafts the fix: an easier Tuesday, a new training block, a note to the athlete. Nothing is written until you Approve.
Drafts are the default. If there is a routine action you trust, you can choose to let that one run on its own. 14-day free trial, unlimited athletes, no card required.
The new age of coaching
Coaching used to mean reading every number yourself, or guessing when there was no time. Matter reads it for you, athlete by athlete, and hands you the decision with its reason.
Every Draft starts from the athlete’s training, sleep, HRV, check-ins and wearables, and shows the numbers it used.
Tyler: readiness 52 against his usual 79, sleep 5.4 h, “Slept 5 hrs. Bio exam tomorrow.”
Nothing is written until you Approve. The reason stays with each change, and the calendar and the athlete’s app show the same thing.
Draft, then Approve, then on the calendar and in the athlete’s app.
Matter reads the whole roster, tells you who needs you and why, and drafts the program, the easier day or the note you would have written.
4 of 11 need a look this morning. Three changes wait in Needs review.
Each athlete is read against their own baseline, not the team average, and every plan, session and nutrition target is theirs.
Marcus gets one set fewer. Julie gets mobility. The rest stay on plan.

Who needs me this morning, and why?
Matter
Four athletes need you. Start with the lowest readiness. Tyler Brooks: readiness 52 against his usual 79, sleep 5.4 h, HRV 64 ms against 78 ms. He wrote “Slept 5 hrs. Bio exam tomorrow.” Last Thursday’s sprint faded from 25.4 to 27.6. The draft replaces the 55 min, 3,200 yd sprint with an easy swim. Marcus Johnson: readiness 48, sleep 5.3–5.9 h. “Shoulders are heavy again. SAT prep ran late, really tired.” Shoulders have come up in 7 notes in a row. The draft is one set fewer. Julie Keating: readiness 45 on 3.6–4.5 h of sleep. “Baby was up every two hours. Running on empty.” The draft is mobility, no main set. Owen O'Brien: readiness 59, sleep 5.5 h. “Tired. Two tests this week.” Watch. No change yet. Maya Patel is at 95 after 9.1 h of sleep and stays on the full session. Nothing is written until you Approve.

Whoever you coach
The roster on this page is a swim team. Matter works the same way for a football staff, a running club, a trail and ultra group, a gym or one coach with a handful of clients: each athlete read on their own numbers, each change drafted for you to approve.
Football, basketball and soccer: position groups, minutes and match load, with readiness beside the practice plan.
Sixty runners in four groups, read every morning. Paces, mileage and vert per runner, road, trail or ultra, from whatever watch they wear.
Swim, bike and run in one readiness view per triathlete, with the week adapted when the picture changes.
Yardage against readiness, dual-session recovery and taper timing, swimmer by swimmer.
Sprinters, distance, jumpers and throwers on one platform, with changes drafted by event group.
Programming with readiness, recovery and completed work kept next to the set you are about to change.
Athletes, coaches and the facility in one workspace: classes, programming, notes and messages.
One athlete or thirty. The assistant, the builder, readiness and the approval inbox come with the Pro plan.
Readiness and risk flags across every roster, with the reason, the notes and the coach’s decision kept together.
How it works
01Ask
The assistant is docked on every coach page, by text or voice, and answers in Slack too. Build Thursday’s lift. Who needs an easier day? Plan the next four weeks for the sprint group.
02Matter reads
Training planned and done, readiness, wearable data, check-ins and nutrition, for the team or the one athlete you are looking at.
03Draft
You see what it touches, the before and after, and why. Edit it, ask for another pass, or Skip and nothing changes.
04Approve
The session goes on the calendar and into the athlete’s app, the program updates, or the message sends. Sent keeps the record.
What you can do in Matter
Each of these is a page you can open today, with the assistant beside it.
Programs
Give the goal, the length and the sessions per week and Matter drafts the block. Talk it through in program chat, edit any week on the overview, and assign it to an athlete or a group.
Calendar and workouts
Build a workout row by row or from a photo of the whiteboard. A drafted move shows where it would land, and the calendar changes when you Approve.
Readiness
A daily readiness read for each athlete from check-ins, sleep, HRV and training load. The dashboard lists who needs a decision, and you can ask Matter who needs attention and why.
Drafts and Approve
Drafts from every page, each with its reason. Approve, Edit or Skip one at a time, or all at once. Sent keeps what went out.
Messages and email
Ask Matter to write to an athlete, in the app or by email. Each message waits as a Draft you read first. Email goes from Matter’s address today; sending from your own Gmail is in private testing while Google reviews it.
Nutrition
Build a plan by hand, upload a sheet, PDF or photo of one you already have, or ask Matter to draft it. See what each athlete ate against what training asked for.
Check-ins and forms
Athletes log how they feel in a few taps. Check-in sequences go out on your schedule, replies land on the Check-ins page, and intake forms collect what you need when someone joins.
Connect tools
Athletes link their watch or app from the Matter app; you connect your own tools on one page and see whether data is arriving.
Every connection and how it worksThe athlete app
Athletes see the week you wrote, log sessions and check-ins, read your messages and their nutrition plan, and sync Apple Watch through Apple Health. On iPhone, with a web version for everyone else.
See the athlete appWhere you already work
Coaching staffs live in a group chat. Matter answers from inside Slack, using the same athlete data as the web app, and anything that changes a session still waits for approval.
Coach
who should back off today?
Matter
Four. Tyler Brooks — readiness 52 against his usual 79, 5.4 h of sleep, bio exam tomorrow. The draft is an easy swim instead of the 55 min sprint. Marcus Johnson — readiness 48, shoulders heavy in 7 check-ins. The draft takes one set off. Julie Keating — readiness 45, 3.6–4.5 h of sleep, mobility and no main set. Owen O’Brien is a watch, no change yet. Nothing is written until you Approve.
Answers are grounded in that athlete’s real data, and anything that changes a session still comes back to you for approval.
Ask about any athlete from the channel your staff already has open.
Assistants, interns and the athletic trainer get the same answers without another login to remember.
The same assistant, docked beside every page of the web app.
Type or speak the question from the field. Changes come back as Draft cards you Approve, Edit or Skip.
Routines
Write it the way you would ask for it, then choose the days and the time. Each run works through the roster and files what it drafts in Needs review. Pause a routine or run it now from the same page. Routines are on the Team and Enterprise plans.
From the Routine Hub
Underneath
Each athlete gets a daily readiness read, built from whichever of check-ins, sleep, HRV, and training load they have.
When Matter drafts a change, the draft carries its reason, so you can check it before you Approve.

Why Matter exists
Coaches spend hours reading data before practice, and athletes wear devices that never turn into a plan. Matter reads the roster and drafts the next step with its reason. You decide what happens.
Founded by a D1 athlete and certified athletic trainer who spent years watching coaches manually review spreadsheets while athletes wore expensive wearables with no way to act on the data.
Every AI action is drafted for your review by default, and nothing goes out until you approve it. Once you have approved the same routine action consistently, you can choose to let that one run on its own. The coach stays in control.
AI responses cite published sport science found via live web search, plus built-in NSCA and ACSM training guidance. Readiness models are built on established recovery science, not proprietary black boxes.

Questions
What coaches ask before they start.
Matter is an AI coaching workspace for coaches and teams. Your calendar, programs, athletes, messages, check-ins and nutrition plans are in one place, with an AI coach on every page. Ask it for a change in plain words; it drafts the change with its reason, and nothing is written until you Approve.
Coaches who plan training for other people: independent coaches and trainers, clubs, gyms and classes, and school or college teams. It works for one athlete or a full roster, across endurance, strength and team sports.
Sign up, create your team, add athletes with the team link or a roster file, connect your tools, ask Matter for something, and generate a first program. The Get started guide in the app walks you through each step. Read the getting started guide
It generates programs, builds and adjusts workouts, moves sessions on the calendar, writes messages to athletes, drafts nutrition targets, and answers questions about the roster, such as who needs attention today. It reads the team’s training, readiness, check-ins and nutrition first. Each change arrives as a Draft you Approve, Edit or Skip.
Athletes connect Apple Health (for Apple Watch), WHOOP, Strava, Polar and Google Health, which brings in Fitbit and Pixel Watch. Garmin data reaches Matter today through Strava or Apple Health; a direct Garmin connection is in progress. For strength work, GymAware and Hawkin Dynamics connect, and any VBT or force-plate export can be uploaded as a CSV. See every connection and how it works
No. Athletes can log how they feel in daily check-ins, and readiness uses whatever each athlete has. A watch or training app adds detail when an athlete connects one.
Athletes join from the team link you send them and can use Matter on the web or in the Matter app for iPhone. The iPhone app is what syncs Apple Health, so athletes with an Apple Watch should install it. See the athlete app
Athletes choose which metrics their coach can see, and leaving a team removes the coach’s access. Matter does not sell, rent or trade personal information or health data to third parties for advertising or marketing. The privacy policy explains how Matter handles health and training data.
