MechOwl Design Review AI
- Unit: 1 cr (credit) = ¥110 incl. tax / ¥100 excl. tax
- Drawing (long side up to 420 mm: A3, A4, etc.): 10 cr per page = ¥1,100 incl. tax / ¥1,000 excl. tax
- Large drawing (long side over 420 mm): 20 cr per page for every 1,189 mm of the long side = ¥2,200 incl. tax / ¥2,000 excl. tax. A2 to A0: 20 cr; a long side of 2,000 mm: 40 cr
- Photo of a drawing: 10 cr per photo = ¥1,100 incl. tax / ¥1,000 excl. tax
- Part numbers: Part research and attached parts lists are included in the drawing charge. For every 10 cr of drawing charges, up to 50 part numbers of general-purpose parts are looked up (at most 150 per review; part numbers on the drawing and in the parts list are counted together, and the same part number counts once). When the cost limit is reached, and for parts beyond that, we provide links to the makers and a checklist.

- Returns, cancellation and plan cancellation
For the user's own reasons
As a digital service, a confirmed purchase cannot be returned or cancelled. A review can be cancelled before processing starts, and the credits held for it are returned (Article 7(3) of the terms). A monthly plan can be cancelled on the account page at any time and ends at the first renewal date after the request; credits already granted remain usable until they expire (Article 9(3)). Unused credits lapse when the account is closed and are not refunded, except in the cases set out in Article 4(3), Article 11 and Chapter 8 (special provisions for individual users) (Article 20).Because of a fault in the service
If all or part of a review is not completed for reasons attributable to us, the credits for the part not completed are returned (Article 7(4) of the terms). If those credits have already expired, the same number of credits is granted free of charge (valid for 30 days from the grant; Article 11(5)).- Refunds
For the user's own reasons
Fees paid and credits bought are not refunded, except in the cases set out in the terms and where the law requires a refund. Cancelling a monthly plan gives no pro-rata refund (Articles 9(3) and 11(1) of the terms). Individual users are also refunded where the Consumer Contract Act or other laws require it (Article 32).Because of a fault in the service, etc.
If the whole service cannot be used for 30 or more consecutive days for reasons attributable to us, if we end the whole service, or if we end part of the service and the user asks by the end date, unused bought credits (credit packs, top-ups, and Enterprise credits granted on an invoice payment) within their validity are refunded. For each purchase, the refund is the amount actually paid (incl. tax) divided by the credits bought, times the unused credits, rounded up to the yen. In these cases a monthly plan can be cancelled without penalty, and the monthly fee (incl. tax) is refunded pro rata for the days from the day after cancellation to the end of the current period (rounded up to the yen). Credits granted with a monthly plan and credits granted free of charge are not refunded (Article 11(2)-(4) of the terms).- Requirements
