FAQs

No. Start with whoever you want and add the rest at your own pace.

You can start with the USD 0 Free plan for up to 3 clients and explore onboarding, routine creation and tracking.

You replace it gradually: chat and tracking live in your client's app.

If you use WhatsApp and a spreadsheet, you can use Kaizer. We built it so the technology adapts to you, not the other way around.

Kaizer is an AI app for personal trainers that combines routine creation, client tracking and business workflows in one platform. It builds a starting point from goals, preferences, limitations and equipment, then adapts loads after each logged session while the coach stays in control. It was founded in 2024 by Agustín Anfosso, Pedro Guarga and Octavio Serpe.

Kaizer combines programming, tracking, chat and a client app with an engine that uses sets, reps, RIR and estimated 1RM to adapt loads after each logged session. To evaluate other platforms' features, use the comparison pages with visible sources and review dates.

Kaizer focuses on personal trainers: individual routines that adapt after every session, a client dashboard, and a mobile app for clients. We do not publish gym-operations features or gym-specific plans.

Kaizer centralizes programming, logs, tracking and communication, so coaches can use the same workflow around in-person sessions, online coaching or a combination of both.

Yes. You upload the file and Kaizer builds the routine or training plan inside. It accepts PDF, DOCX, XLSX, CSV, TXT and images in JPEG, PNG or WEBP, up to 500,000 bytes per file. The legacy .doc and .xls formats are deliberately left out because the importer does not read those binaries: if you have one, save it as .docx or .xlsx and upload that. The file is never stored anywhere.

Yes, but Kaizer does not move the money. You record each client's charge and its frequency (weekly, fortnightly, monthly, quarterly or biannual) and the platform shows you who is up to date, whose payment is coming due and who owes you, with history and automatic reminders. When they pay you, you record the payment and the method. You keep getting paid the way you get paid today; what you stop doing is keeping the ledger in your head.

Yes. You can create group chats with no participant limit, useful for coordinating schedules, announcing a change of routine or running a group that trains together. In any chat, one-to-one or group, you can send images (JPG, PNG, WEBP, HEIC), video (MP4, MOV, WEBM), audio (MP3, M4A, OGG, WAV) and documents (PDF, DOC, DOCX, XLS, XLSX, TXT, CSV), up to 50 MB per file, and the links you share render as a card with title and image.

Yes, and it is the biggest difference from the rest of the software in this category, which helps you manage the clients you already have. You publish your profile in the Kaizer marketplace and people looking for a trainer find you there. On average, a published trainer picks up 2 new clients a month. The booking closes inside the marketplace, so you do not have to set up collection or checkout yourself.

No. AI creates routines and adapts loads from logged sessions, but the coach keeps professional control: they can review and edit the programming and decide how each adjustment applies to the client's context.

Yes, practically the whole platform can be operated by talking to it. The assistant can build and clone routines, edit sessions and exercises, manage training plans, search the exercise library, and pull your business metrics and a specific client's analytics. It works by text or by voice, with automatic audio transcription, and every new feature adds its own. You can also link your account to Claude and drive Kaizer from there.

We call it assisted progression. After every session your client logs, Kaizer reads the sets, reps and RIR they reported, recalculates the estimated 1RM and proposes the loads for the next session. The adjustment goes through you before your client sees it, and you can accept it, change it or throw it out. The machine does the arithmetic; the judgment stays yours.

Public plans are Free (USD 0, up to 3 clients), Starter (USD 19/month, up to 15), Pro (USD 49/month, up to 50) and Unlimited (USD 149/month, up to 500). Annual billing with published monthly equivalents is also available at kaizer.app/en/pricing.

Yes. You can start with the USD 0 Free plan for up to 3 clients at kaizer.app and evaluate routine creation, tracking and the client app before moving to a paid plan.

You share your link and the trainer who signs up with it gets their first month free when they pick a paid plan. You earn USD 30 once that trainer completes 2 paid months. The link comes from your KaizerTag, so it is always the same one.

Yes. Kaizer supports USD, ARS, EUR and BRL, with local currency by country where applicable. Publishable payment methods are Stripe, Mercado Pago and card payments.

Kaizer operates globally and is already present in 20+ countries. Public markets are Latin America, the United States, Canada, Spain and Portugal; the product is available in Spanish, English and Portuguese.

Yes. Clients use the Kaizer mobile app on iOS or Android to view routines, check videos and timers, log workouts and keep communication connected to their training.

Yes, and they are two separate apps. Your clients use Kaizer, where they see their routine, the videos and their progress. You use Kaizer para Coaches, which is the dashboard on your phone: your clients, their plans, the chat and the assistant. Both are on iOS and Android, in Spanish, English and Portuguese.

Both. Units are a setting, not a locale: you pick metric or imperial as your default, and each client can be on the other one. The choice is stored with every routine and every logged session, so weights, loads and body measurements read in pounds for the clients who use pounds and in kilos for the rest, and the load increments follow the same system.

No. Kaizer's scope is training and programming. It does not generate macros, diets, meal plans or supplementation recommendations.
