Plans and credits

JST4 turns a dialogue into an original animated video with synthetic audio. A paid subscription is required to create exports. Prices are in EUR and are the amount charged. Your bank may convert to your card's currency at its own rate.

Subscriptions

Starter — €9.99/month or €99.90/year. Includes 150 credits each month: up to 15 music generations and 30 audio tracks to choose from.

Creator — €34.99/month or €349.90/year. Includes 500 credits each month: up to 50 music generations and 100 audio tracks to choose from.

Pro — €49.99/month or €499.90/year. Includes 1,300 credits each month: up to 130 music generations and 260 audio tracks to choose from.

Annual plans are charged once per year and issue the stated credit allowance monthly. Subscriptions renew automatically unless cancelled in the Studio before the next billing date.

Additional credit packs

Active subscribers may buy optional credit packs: 100 credits — €7.99 (up to 10 generations / 20 tracks); 200 credits — €14.99 (20 / 40); 500 credits — €34.99 (50 / 100); or 1,000 credits — €69.99 (100 / 200). Purchased credits do not expire while the subscription is active and are used after the current subscription allowance.

Using credits

A credit is an internal JST4 usage unit, not money or a payment method. One music generation costs 10 credits and returns two audio tracks; the creator selects the preferred one for the video. The credit cost of every paid action is displayed before it starts. Other modes and longer scripts may use a different amount, shown in the Studio before confirmation.

Payment, cancellation and refunds

Payments are securely processed by WayForPay; JST4 does not store card data. You can cancel at any time in the Studio, under subscription and payments; cancellation takes effect at the end of the paid period. Read the public offer, refund policy and privacy policy before purchase.
