You to your AI

“Add front squats to my workout.”

Real Noostaa workout screen: front squat, set 1 of 3, 8 reps at 60 kg
Your workout, ready in Noostaa

Plan. Train. Share feedback. Repeat.

Your AI assistant writes the plan. Noostaa helps you follow it and record what happened, so your assistant can adapt the next workout.

  1. Plan with your AI

    Tell your connected assistant your goals, equipment, and time. It saves your workout to Noostaa.

  2. Train in Noostaa

    Open the app and follow your exercises, sets, loads, and rest. Apple Watch is optional.

  3. Log how it went

    Record reps, weight, effort, changes, and anything you skipped while the session is fresh.

  4. Adapt the next workout

    Ask your assistant to use your saved training history and feedback when planning what comes next.

ExampleClaude, planning Thursday: “You finished every front squat set at effort 7, so the load goes up 2.5 kg. Your left knee flagged on split squats, so this week is step-ups instead.”

Connect your assistant

Connect once. Then just ask for a session.

Noostaa works with any assistant that speaks MCP, and with the Noostaa CLI for custom agents. Sign in once and your assistant can send workouts and read how they went.

Before you connect: install Noostaa on your iPhone, sign in, and start the free trial or a subscription. Assistant tools only work while the subscription or trial is active, and you must sign in to your assistant with the same Noostaa account.

  1. Turn on developer modeOpen ChatGPT on the web and go to Settings → Apps & Connectors (named Connectors or Apps on some plans). Under Advanced settings, turn on developer mode. If you don't see it, your plan or workspace admin may need to allow custom connectors.
  2. Create the Noostaa connectorChoose Create, name it Noostaa, enter the server address below with OAuth authentication, and follow the prompts to sign in to Noostaa.
  3. Plan your first workoutIn a new conversation, add Noostaa from the tools menu (or type @ and select it), then ask: “Check what's new in Noostaa and help me plan my next workout.”

Ready to train

Connect. Plan. Train.

Sign in with the same account you use on iPhone. Return to Noostaa after connecting; the app checks the connection and shows its status.

Automatic planning

After connecting, ask your assistant:

Use my Noostaa feedback and equipment to prepare my next workouts regularly. Help me set up the planning skill and a schedule if you support them.

If your assistant has the Noostaa planning skills installed, use schedule-session-planning. Choose your training days, when to prepare workouts, and whether to save them automatically. Confirm the schedule with your assistant. Custom MCP connections alone do not install planning skills or guarantee scheduling support.

If scheduling is unavailable, ask for your next workout manually after each session.

How Noostaa fits into your training

Does Noostaa replace my AI assistant?

No. Your assistant still helps with the thinking: goals, progress, and what to train next. Noostaa is where the workout goes when it is time to move.

Which assistants does Noostaa work with?

Noostaa is built for workouts planned with ChatGPT, Claude, or your own AI assistant. It can connect through MCP where supported, or through the Noostaa CLI for custom agent workflows.

Which devices does Noostaa support?

Noostaa supports iPhone for following workouts and Apple Watch for workout recording.

Do I need a paid AI assistant?

It depends on the assistant you use and how much you use it. Some assistants may require a paid plan, higher usage limits, or access to tool connections such as MCP.

Does Noostaa replace my AI subscription?

No. Noostaa is a complement to your AI assistant. Your assistant subscription, limits, and billing stay separate from Noostaa.

Is Noostaa free?

Eligible new subscribers can try Noostaa free for seven days, then continue with a small monthly subscription. See your local price in the app before subscribing. Your subscription renews automatically unless you cancel before the trial ends.

Why not just keep the workout in chat?

Chat is great for planning. Training needs a dedicated flow: clear steps, rest timing, quick notes, and feedback you can leave before you forget how the session felt.

What does Noostaa remember?

The useful training signals: what you completed, what you skipped, how hard it felt, and what should change so your assistant can plan better next time.

Your next workout is one message away.
