Pricing

Usage is counted in Standard Tokens, and each plan comes with a monthly allowance. Every plan lets you hand work to AI roles, with approvals and an audit log.

7-day free trial

Use 1M Standard Tokens free for 7 days. After 7 days the plan you chose renews automatically (cancel during the trial and you won't be charged).

Work stops at your allowance

We never bill you for usage beyond your allowance. You buy add-on packs yourself, and you decide whether to change plans.

  • Activity record (audit log)
  • Notifications at 80% / 100% of your allowance

Use 1M Standard Tokens free for 7 days — about 4〜6 Sonnet requests. Up to 1 user and 2 AI roles. You add a card when you start, and the plan you chose renews automatically after 7 days. Cancel during the trial and you won't be charged.

Add-on pack

5M Standard Tokens

¥5,500 tax incl./¥5,000 excl. tax

Top up only what you need when your allowance runs out (prepaid). Packs don't expire while your subscription is active. Your plan allowance is used first, then the pack. We never buy a pack for you.

What is a Standard Token?

Skix One counts usage in Standard Tokens (ST). Because cost per request varies by AI model and task, we convert actual cost into one common unit.

As a guide, 1M Standard Tokens ≈ ¥1,000 (excl. tax).

One Sonnet request uses about 200K Standard Tokens (actual usage: median 160K, mean 240K).

Long research or large files use more; short classification or summaries use less.

Pricing FAQ

Is there annual billing?
Yes. Pay for 10 months and use it for 12 (2 months free). Standard tokens are still granted month by month on annual billing, not all 12 months at once.
Do plans renew automatically?
Yes. Monthly and annual plans renew automatically. You can cancel anytime and keep using the service until the end of the current period (no prorated refunds). If you subscribed through the App Store or Google Play, cancel from that store's subscription settings.
What happens when I use up my allowance?
AI work stops for the rest of the month. You'll be notified and can choose to buy an add-on pack or change plans. We never bill you for the overage or add a pack on your behalf. Scheduled tasks are skipped and you're notified in your inbox.
Does unused allowance roll over?
Monthly allowances don't roll over. Add-on packs don't expire while your subscription is active.
Can I change plans mid-cycle?
Upgrades take effect immediately and the difference is prorated. Downgrades take effect from the next billing period.
Could a single request use a lot?
Each request is capped at 2M Standard Tokens. If a request is about to exceed it, we stop and let you know. You can change the cap in settings.
Is the price the same in the mobile apps?
Yes. The iPhone and Android apps (coming soon) use the same prices as the web, and a plan bought anywhere works everywhere. App Store and Google Play prices follow each store's regional price tiers, so they may not match to the yen.
Do prices include consumption tax?
The large figures include Japanese consumption tax (10%). Prices excluding tax are shown alongside.
  • ※ All prices are in Japanese yen. Large figures include consumption tax (10%).
  • ※ Request counts are estimates based on actual Sonnet usage from July–November 2026 and vary with the task.
  • ※ Prices on the App Store and Google Play follow each store's display (tax included).
