You coach. Spotter does the admin.

The AI assistant for personal trainers. Free. Ask for a 4-day split, a 2,200 kcal meal plan or a message for Monday at 6:30. Spotter builds it from your athletes' data, and nothing changes until you say OK.

How it works

One sentence. One card. Your OK.

Watch Spotter write Alex a week, then walk through every screen it works in, in the order a week runs. Each one is yours to use by hand too.

Spotter

Say it. Approve it.

Tell Spotter what you need, the way you'd tell a colleague. It reads up on your athlete, builds the workouts and the meal plan, schedules messages and reads reports, and holds every change on one card until you say OK.

Or do it yourself

Every screen Spotter works in is yours too. Here is a week of TrainKeep, in the order it runs.

Build

Write the week once.

Workouts with your own columns, a routine across the week, and a meal plan that does its own maths — written on the athlete's own page and saved as you go.

Train

Logged on the gym floor. Even with no signal.

Athletes log every set in the app. No signal? Each set saves on the phone and goes out the moment it's back.

Check in

Check-ins that arrive on their own.

Pick the days and the hour. They send their weight, measurements, photos and answers to your questions, and it all lands in their log.

Talk

Say it now. Or say it Monday at seven.

One thread per athlete, where their form checks and workout notes arrive as cards you answer — and anything you write can go out later, on your clock.

Measure

Proof they can hold.

Every lift and measurement charted, and a progress report you print, save as a PDF, or share straight into their portal.

Paperwork

And the paperwork signs itself.

Send your agreement; they sign it with a finger, and the signed PDF files itself with who signed and when.

Questions coaches ask first

  • Is TrainKeep really free?
    Yes, and not as a trial. The Free plan is yours for good: up to 20 clients, every coaching tool, and 5 client portals (the personal logins your athletes use to see their plan and log their training). No credit card. The paid plans add room, not features: Solo holds 200 clients and 30 portals, Pro holds 2,000 and 100. Prices for your country are in the plans above.
  • Does Spotter change anything without asking me?
    No. Lookups answer straight away, but every change (a workout, a meal plan, a message, a check-in) waits on a card that shows exactly what will be written or sent, down to the date, the time and the words. Nothing happens until you say OK, and afterwards you're taken to where you can see the result.
  • Is Spotter included on the Free plan?
    Yes. Every plan comes with Spotter. The Free plan includes an allowance to try it (confirm your email address first); Solo and Pro come with more, and theirs refills every month. You see what you've used as a percentage, and if you run out, everything else in TrainKeep keeps working as always. Need more at any point? Top up Spotter from your billing page; a top-up never expires.
  • Where do Spotter's numbers come from?
    From your account. Spotter reads your athletes' logged sessions, body numbers and plans, and TrainKeep itself works out every total, calorie and macro, then checks each number in Spotter's reply against where it came from. Foods come from your own food list first, then the USDA food database; Spotter never invents a food's macros.
  • Do my athletes talk to Spotter?
    No. Spotter works for you, the coach. Your athletes see only what you approve: the workouts, meal plans, messages, check-ins and reports it prepared for you.
  • Can I try it before adding real clients?
    You don't have to add anyone. Every account opens with a fully built example athlete: 18 months of logged sessions, a training program, a diet plan and progress photos. That athlete is you, signed in with your own login, so you can open the athlete app and see exactly what your clients will see. Nothing you do there reaches anyone, so rewrite the program, log a session, break things. Keep it, change it, or hide it from your roster.
  • Who is TrainKeep for?
    Personal trainers, strength coaches and nutrition coaches, working one-to-one or with small groups, in person or online. It replaces the patchwork most coaches end up running: a spreadsheet per client, a shared Drive folder, a chat thread and a separate e-sign subscription.
  • Do I need to install anything?
    No. TrainKeep runs in any modern browser, for you and for your athletes, with nothing to install or update. Athletes can also get the app from the App Store or Google Play, which puts TrainKeep on their home screen and keeps logging workouts when the gym has no signal.
  • Which devices work best?
    For coaches, a laptop, a desktop or an iPad. Writing programs, planning diets and reading progress charts is detailed work, and a big screen with a keyboard makes it fast. For athletes, their phone: the athlete app is built for one hand between sets, and a glance at the day's training and meals on the way in. Either side can still sign in on anything with a browser.
  • Can I build workouts, diet plans and supplement protocols in the same tool?
    Yes. Workout, diet and supplement templates sit side by side, macros, portions and doses included. Assign any of them to a client in seconds, then keep adjusting as the training block goes on. Athletes tick their supplements off each day, and you see their week at a glance.
  • Can I review my athletes' lifting technique?
    Yes. Your athlete films a set on their phone and sends it to you as a form check: up to three minutes, tagged with the lift and a note on what felt off. You watch it on their profile and reply in a thread, and they are notified when you do. Nothing needs scheduling. They send one whenever a lift feels wrong, up to ten a day, and each video is kept for a year.
  • Can clients sign contracts and waivers online?
    Yes. Upload your coaching agreement or waiver as a PDF, place the signature fields and send it. Your client signs on their phone, and the signed copy is filed under their name with who signed, when, and from which IP address. No third-party e-sign subscription needed.
  • Does TrainKeep track client progress over time?
    Yes. Body weight, custom measurements, progress photos and session notes are all recorded over time, and the charts draw themselves: weight, measurements and strength trends, readable at a glance.
