Billing F.A.Q.

What is included in DEMO plan?

You can use HARPA for free on a DEMO plan within free limits:

  • Access GPT 3.5, ClaudeAI 2, Gemini on web session connections, limited to 10 message a day.
  • Up to 100 total AI command runs, page-aware, web-aware, and parameterized AI messages.
  • Access to predefined and custom commands, and web monitors.

Upgrade for unlimited power messages, advanced features, AI automation, and stable Cloud GPT connection which features GPT-4 and ClaudeAI 3 Haiku, Sonnet and Opus models.

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 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.

What are Megatokens?

Megatokens are consumed when sending chat requests on the fast and reliable 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-4o tokens cost x10 of GPT-3.5 tokens.

X vs S-tier. Which to pick?

Here's a quick guide to help you decide:

  • S1-tier: Ideal to try out HARPA, track your megatoken consumption, before making a commitment to a larger plan.
  • S2-tier: Comes with GPT4, Claude3 AI models, advanced feature geared towards workflow automation and high megatoken balance.
  • X-tier: Ideal for personal use. It offers a one-time payment option and lifetime access, perfect for users on personal spaces. Does not include Megatokens, which are purchased separately.

Every plan provides unlimited power messages, editing predefined commands, access to chat history and cloud command storage.

Is it possible to change plans?

Any time from Account Settings Page → MANAGE BILLING

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.

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.

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.
  • 300 basic requests in chat on GPT-4o model.
  • 30 page-aware requests in chat on GPT-4o model.

Page and web-aware modes consume more tokens. GPT-4o model has a x10 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.
