Terms of service

Updated October 28, 2026

Using the studio

Dessa AI provides live voice conversations and text-to-speech tools. These terms explain how credits, subscriptions and one-time purchases work.

Current availability: Payments, paid subscription changes and cash refunds are not available at this time. The purchase terms below apply when paid checkout opens; viewing a plan or selecting it does not create an order or charge.

Accounts and acceptable use

Keep your account details secure and use only content and voices you have the right to use. Do not use the service to impersonate someone without permission, commit fraud or infringe another person’s rights. You control when microphone access begins and may end a conversation at any time.

Credits and Pricing

Credits are the usage allowance for both Live Talk and Text to Speech. Both tools draw from the same available balance, so using one reduces the credits available for the other.

  • Live Talk: Each conversation uses 1 credit per 6 seconds of confirmed usage, rounded up to the next 6-second increment. This is equivalent to 10 credits per minute. A connection that fails without confirmed usage costs no credits.
  • Text to Speech: Each generation uses 1 credit per 1,000 input characters, rounded up separately for each request. Letters, Chinese characters, spaces, punctuation and line breaks count. For example, 1,000 characters cost 1 credit and 1,001 characters cost 2 credits. Empty scripts are not accepted.
  • Reservations: Starting a task temporarily reserves credits. For Live Talk, the reservation covers the maximum duration allowed by your plan and available balance. Unused credits are returned after settlement. A TTS request is charged after its audio file has been generated and saved; if generation fails, its reserved credits are returned.
  • Balances: Subscription credits and pack credits are recorded separately within your shared balance. Credits with the earliest expiry date are used first, before credits that do not expire.
  • Prices and estimates: Prices are shown in US dollars. Review the total payable and any applicable taxes at checkout before confirming a purchase. The Pricing page lists current allowances and limits. Estimated Live Talk minutes assume all credits are used for conversations; TTS usage and rounding on individual calls reduce that total.

Subscriptions

Choose monthly or annual billing. Monthly plans are paid one month at a time. Annual plans are paid in full for the year; the monthly figure shown for an annual plan is a price comparison, not a monthly charge.

  • Monthly allowances: Starter includes 700 credits, Pro includes 3,000 credits and Max includes 5,500 credits per subscription month. Annual plans also receive credits monthly, rather than receiving the full year’s allowance at once. Unused subscription credits expire at the end of their monthly allowance period and do not roll over.
  • Renewal and cancellation: Subscriptions renew automatically at the end of each billing period unless cancelled before renewal. You may request cancellation through support@aivoicedessa.com. Cancellation stops future renewals; your plan remains available until the end of the period already paid for. On an annual plan, monthly credit allocations continue through that period. Cancellation does not itself issue a cash refund.
  • Upgrades: Upgrades take effect once the additional payment is confirmed. The price difference is prorated for the remainder of your current billing period. Additional credits are prorated for the remainder of your current monthly allowance period. The amount due and additional credit allowance must be shown before you confirm the change.
  • Downgrades: Downgrades take effect at the next renewal. Your existing plan limits remain in place until then. For an annual subscription, the next renewal is at the end of the paid year.
  • Task limits: Starter allows up to 20 minutes per conversation and 2,000 characters per TTS request; Pro allows 45 minutes and 4,000 characters; Max allows 90 minutes and 5,000 characters. A conversation may end sooner if your available credits run out. New tasks use your current plan limits; a conversation already in progress keeps the limit set when it began.

One-Time Credit Packs

Credit packs are a single purchase with no recurring charge. You can use them without a subscription or add them to an existing subscription balance.

  • No expiry: Purchased pack credits do not expire. Cancelling a subscription does not remove your unused pack credits.
  • Shared use: Pack credits can be spent on Live Talk or Text to Speech at the rates above. The minutes shown for a pack are a total allowance across conversations, not the length of a single call.
  • Plan limits: A pack adds credits but does not upgrade your subscription. Without an active subscription, each conversation is limited to 20 minutes and each TTS request to 2,000 characters. With an active subscription, that plan’s limits apply.
  • Refunds: Each pack purchase is considered separately under the refund policy below. Credits are not automatically converted into cash when you stop using the service.

Refunds

If you change your mind, you may request a full refund within 7 days of your first subscription purchase or any one-time credit pack purchase, provided none of the credits from that purchase have been used.

  • Eligibility: The 7-day period starts when payment is completed. For a subscription, this offer covers the initial monthly or annual payment. For a credit pack, it applies to that individual purchase. A failed task whose reserved credits were returned does not count as used credits.
  • How to apply: Email support@aivoicedessa.com from your account email address and include your order or invoice reference and the purchase date. Do not send your full card number or other sensitive payment details. We will check the payment and credit records and reply with the outcome.
  • After approval: A full refund removes the unused credits associated with that purchase. Refunding a subscription also ends the refunded subscription and any future credit allocations under it. Other, unrelated credit purchases are not affected. Approved refunds are returned to the original payment method; the time before they appear depends on your payment provider.
  • Renewals and other requests: The unused-purchase offer does not automatically cover renewal charges, upgrade charges, requests made after 7 days or purchases whose credits have been used. If you believe a charge is incorrect or a service failure affected your purchase, contact us so we can review it. Duplicate charges and verified billing errors will be corrected, including a refund where appropriate.
  • Credits and cash are different: Returning credits after a failed or partially used task restores your usage balance. It does not return money to your payment method.
  • Your legal rights: Nothing in this policy limits any cancellation, refund or other consumer rights that apply under law.
