Details (how much you can make, what credits are for, classic tools)

Approximate monthly output

  • Watering: 1 (Economy) to 11 (Slow) AI videos of 30 seconds
  • Seed: 4 (Economy) to 25 (Slow) AI videos of 30 seconds
  • Feast: 8 (Economy) to 50 (Slow) AI videos of 30 seconds
  • Full Course: 57 (Economy) to 353 (Slow) AI videos of 30 seconds

Formula: number of videos = monthly credits ÷ (credits per second × 30 seconds), rounded down. Video costs 6.6 credits per second on Slow and 40.26 on Economy, assuming you spend all monthly credits on video. The estimate for novel episodes is still being measured. You can check actual usage in the estimate shown on screen before running.

*6 AI TRPG: Watering and above can play without limit. For fair use, if you exceed 600 turns in a day, you will need to wait until the next day (midnight Japan time). Each conversation with a character counts as half a standard turn. The same applies to yearly and Team plans. During the free period, you can play with that plan's allowance. Features that use AI credits use the same AI credits as other features of the Service.

Prices are public monthly list prices for individuals (tax excluded) as of 2026-10-12 and may change. Yen prices are converted at 1 USD = 150 JPY. Items marked “check” could not be read from the official page and come from comparison articles or earlier list prices.

What AI credits are for

  • Novels: talking with AI, suggestions for what comes next, revising selected text, creating titles, synopses, and plots, and organizing character settings.
  • Manga and images: creating storyboards from a script, and drawing and fixing panels. Usage for 4-panel comics depends on the image model, quality, and number of regenerations you choose.
  • Video, voice, and music: generating shots, voice, song making, and lip sync. AI video costs per second: Slow (fewer credits) 6.6, Economy 40.26, Standard 80.52, Highest quality (Veo 3.1) 402.6 credits (revised October 25, 2026). During the trial, video generation is limited to 1 work and 30 seconds in total.
  • Images, songs, video, voice, upscaling, and cutouts: use credits on every plan, whichever model makes them (*5).

Usage varies with what you make and how long it is, so check the estimate on screen before running. If a generation fails, the reserved credits are returned. Reaching a cap never switches you to paid usage automatically. Every individual plan's first 7-day trial includes 1,000 credits. You can switch to a full subscription during the trial to receive credits right away (you pay for one month from that day and receive the monthly credits immediately; any remaining trial credits stay usable). Yearly plans receive the same monthly credits as monthly plans. Check remaining credits and usage history in Studio

What you can make with credits

  • What you can make: AI video and anime PVs, character sheets, 4-panel comics and manga panels, BGM, songs and voice, image upscaling and background removal.
  • Every plan: generation uses credits (for example, 1.89 pt per image, 6.6 pt per second of video on Slow), shown in the estimate before it runs. You can split your monthly credits (Feast 10,000, Seed 5,000, Watering 2,250) freely across novels, 4-panel comics, character portraits, video, and more.

Terms for subscriptions, billing, and credits
  • Subscribing: you need to sign in to subscribe (after signing in from a subscribe button, you return to the same checkout). Payment is handled by Stripe; you confirm the amount and terms on the checkout page to complete it (pressing a button alone does not create a subscription).
  • Billing after the free trial: Watering, Seed, Feast, and Full Course are ¥0 for the first 7 days, first time only. A card is required when you sign up, and after 7 days you are charged the monthly price of the plan you chose (the yearly price for yearly billing; for example, Watering ¥1,650 / mo (incl. tax · ¥1,500 excl. tax), Feast ¥5,500 / mo (incl. tax · ¥5,000 excl. tax)). Cancel from My Page by the day before and you won't be charged. Even after you schedule a cancellation, you can keep using it until the end of the period (during a free trial, until the trial ends). The trial includes 1,000 credits; videos are limited to 30 seconds each.
  • Renewal and yearly billing: monthly plans renew automatically every month, yearly plans every year. Yearly billing costs 10 months of the monthly price (2 months free), with the same monthly credits as monthly billing. Priority uses on yearly plans are given all at once at the start. You can check your renewal date and cancel in subscription management.
  • Credits: monthly credits can be used at any time (there are no short-term limits such as every few hours or weekly). Unused credits roll over for up to 3 months, up to 2x the monthly amount, and the oldest are used first (trial credits and the Team & Business organization pool do not roll over). When you run out, you can continue with pay-as-you-go or prepaid packs, only if you agree. If you upgrade mid-month, the difference in that month's credits is added right away.
  • Commercial use and ads: you can use what you make commercially (Terms of Use). Ad campaign and design editing (3 campaign ideas from product information, banners and flyers in 70 media sizes, pre-submission checks, client review links, ZIP delivery) and the corporate PR manga maker are available on all paid plans (how to use).
  • *1 When things are busy, there may be a wait.
  • *2 Increasing the number of choices reduces the maximum generation length per choice. "Generation length per choice × number of choices ≤ the plan's maximum generation length."
  • *3 Hiding ads may take some time to take effect. Automatic ads may appear on other pages.
  • *5 Generation and credits: on every plan (including Feast, Full Course, and Team), generating images, songs, video, voice, upscaling, and cutouts uses credits. You see the credits in the estimate before it runs. When things are busy, jobs may start later. See the Terms of Use for details.
