Billing F.A.Q.

What is included in FREE plan?

HARPA is a freemium app. Free features include:

  • Unlimited basic messages on Web Session and API Key connection.
  • Daily rate-limited Power Messages: commands, page-aware, web-aware, and parameterized AI messages.
  • Access to 100+ predefined commands.
  • Web page, price, and data monitoring.
  • Limited custom commands, automations, and more.

Upgrade for unlimited power messages, advanced features, AI automation, and Cloud GPT connection (coming soon).

What are Power Messages?

Power Messages are AI commands, page-aware, web-aware or parameterized AI messages sent in chat. Power messages have a daily rate limit on Free plan.

Upgrade to X or any S-tier plan for unlimited power messages.

What are Spaces?

Space is a personal, team or organization workspace, and is a place for storing your commands.

On S plan you can connect multiple members to your space to share commands across your team and organization. S-tier subscriptions are purchased per space and billed per number space members.

X plan activates for PERSONAL spaces only.

What are Megatokens?

Megatokens are consumed when sending chat requests on the fast HARPA Cloud GPT Model.

1 Megatoken is 1 million GPT-3.5 input tokens and is roughly 750.000 words of input text in English.

Output tokens cost x3 input tokens. GPT-4 tokens cost x20 of GPT-3.5 tokens.

X vs S-tier. Which to pick?

Here's a quick guide to help you decide:

  • X-tier: Ideal for personal use. It offers a one-time payment option and lifetime access, perfect for users on personal spaces.
  • S-tier: If you need advanced features, multi-user spaces, or want to try HARPA before committing to X-tier. S-tier plans are subscription-based, billed by the number of users in your space. They come with extra features and will include Megatokens in the future.

Both X and S-tier plans provide unlimited power messages, editing predefined commands, access to chat history and cloud storage.

Is it possible to change plans?

Any time from Account Settings Page → MANAGE BILLING

You are eligible for a one time discount of the X plan price if you decide to upgrade from X plan to an annual S-tier plan.

You can switch between monthly and annual billing by cancelling your current subscription, waiting for it to expire and resubscribing for a new term.

If you purchased an X plan, you will always retain it on your account, even if decide to upgrade to an S monthly or yearly plan.

How do I cancel subscription?

Can I change my payment method?

How many queries is in 1 Megatoken?

Queries vary in size. On average, 1 Megatoken is:

  • 3000 basic requests in chat on GPT-3.5 model.
  • 300 page-aware requests in chat on GPT-3.5 model.
  • 150 basic requests in chat on GPT-4 model.
  • 15 page-aware requests in chat on GPT-4 model.

Page and web-aware modes consume more tokens. GPT-4 model has a x20 cost of GPT-3.5 model.

Why Megatokens and not Query limits?

Token-based billing provides more transparency compared to query-based billing because query sizes can vary significantly.

HARPA AI acts as an AI automation agent and may consume more tokens when used for large-scale automation tasks.

With HARPA, you can easily monitor the exact number of tokens used for each query, ensuring clear and precise control over your usage.

What payment methods supported?

The billing is managed by FastSpring, BrightMarket LLC, secure and trusted global payment service provider.

FastSpring supports all major credit and debit cards, PayPal, Amazon Payments, ACH direct deposit, Payoneer Prepaid MasterCard, and international ACH direct deposit.
