Payments are generally non-refundable after access is activated, including for disliked, inaccurate, or unsuitable responses. Cancellation stops future renewals; it does not request a refund. Your legal rights still apply. Read the billing and cancellation policy

Plan facts, refunds, and privacy
  • Agents provide AI-generated text assistance. They do not send messages, connect to your accounts, process uploaded files, or create finished media files.
  • Usage limits and service availability apply. Access does not promise unlimited use or guaranteed results.
  • Chat connection safeguard: 50 counted session openings per account, shared across Agents. The counter resets one hour after the last counted opening.
  • At the limit, another session opening is refused until the counter resets. An unsuccessful connection attempt can still count.
  • Opening a session is different from sending a message. This safeguard is not a message allowance. Usage and availability limits may also apply within a conversation.
  • The individual-Agent and all-Agent plans use the same account-wide connection safeguard. Opening an Agent chat requests a session; refreshing, opening another tab, or reconnecting can request another. Revising in an already connected conversation does not itself call this session-opening endpoint.
  • A refused opening does not add to the count or extend its reset. When the reset time is available, the workspace shows when to try opening the Agent again. The connection safeguard does not specify how many useful drafts or messages a subscription includes.
  • Manage future renewals in Account & Billing → Subscriptions. Cancellation and a refund are different actions.
  • Payments are generally non-refundable after access is activated, including for disliked, inaccurate, or unsuitable responses. Cancellation stops future renewals; it does not request a refund. Your legal rights still apply.
  • Your prompts and relevant context are sent to the enabled AI service to generate a response. Avoid confidential, regulated, highly sensitive, or unnecessary personal information. Retention and deletion depend on the service and provider; read the Privacy Policy before sharing work.
  • For billing or access help, email help@ai-gen.co. Include your account email, order number, Agent name, and a short description of the issue. Do not send passwords, payment-card details, or confidential prompts.
  • If a payment has already been taken but access is missing, review your existing order and contact support before buying again. Report duplicate charges or billing errors through the same route. Any remedy follows the billing policy and applicable law.

Prepare an estimated maximum heart rate and a written set of cardio training zones by sharing your age, the formula or method you want to use, and any workout context that matters. The Agent can compare common age-based estimates and explain how the resulting zones are calculated, so you can review the approach and ask for a revised version with different assumptions.

What it writes

  • A maximum-heart-rate estimate with the formula and arithmetic explained
  • A side-by-side written comparison of selected estimation methods
  • A calculated heart-rate zone guide with its assumptions stated

How to use it

The task is framed around your chosen age, formula, and workout context, with calculations and assumptions laid out for review. You can follow up to compare another method, adjust the supplied estimate, or request a clearer explanation of the resulting zones.

This workspace provides text assistance.

What you bring

  • Your age, or the age range you want used in an estimate
  • The formula or method to apply, if you have a preference
  • Optional workout goals or context to guide the zone explanation
  • Have your age or the estimate you want to use available in chat
  • For a zone guide, choose a formula or provide a maximum-heart-rate estimate

A good fit for

  • Comparing age-based maximum-heart-rate estimates
  • Understanding how heart-rate training zones are derived from an estimate
  • Preparing a written zone guide to discuss or use when planning cardio

Ways to start

A few requests this Agent can handle.

Estimate my maximum heart rate using [age] and [formula], and show the calculation.

Compare [formula A] and [formula B] for someone aged [age]; explain how the estimates differ.

Using an estimated maximum heart rate of [value] bpm, draft cardio zones and explain the calculation for [workout goal].

What this Agent does not do

It does not carry out actions in other applications.

  • Diagnosing a heart condition or determining a medically confirmed maximum heart rate
  • Personalized medical clearance or treatment advice, especially for symptoms or health conditions
  • Calculations and zones are written estimates based on the information and method supplied; they are not measured or medically verified.
  • The Agent cannot assess your body, monitor exercise, or replace advice from a qualified health professional.
