OUTPUT
Output example
Findings
Concerns to verify on that drawing, from the viewpoints of manufacturing, assembly, maintenance and strength.
Basis
For each finding, the basis from the drawing and the source of the part specifications.
Missing information
Parts of the drawing that could not be read, and parts whose specifications could not be confirmed.
The figure shows the layout of the results screen.
AT A GLANCE
At a glance
- Input
- Equipment drawings (PDF or photos) and operating conditions. A separate parts list is checked with them.
- Output
- Findings, their basis and missing information. Results can be output as an A3 report.
- Scope
- Drawings of manufacturing equipment. A3, A4 and other sizes, including large-format drawings.
- Pricing
- 1 cr = ¥110 incl. tax / ¥100 excl. tax. A standard drawing (long side up to 420 mm) is 10 cr = ¥1,100 incl. tax / ¥1,000 excl. tax per page. On sign-up, 10 cr (one page) can be used free of charge.
- Data
- Drawings are not used to train AI. The original drawing is deleted automatically 24 hours after the review ends. The page images shown with the results are kept as long as the results, and can be deleted at any time.
For large-format drawings and photos, see the price table on the products page.
PROBLEMS
Sound familiar?
No time before design review
No time to find omissions and inconsistencies in drawings.
Checking part specs is hard work
Finding each maker's documents for every part number takes effort.
Checks vary by person
Depth and viewpoints of a check depend on experience.
Missed in DR, a fault later
Concerns missed in design review surface after start-up as breakdowns, rework or stoppages.
FEATURES
Features
Part specs cross-checked
Compares purchased parts on the drawing with the specs in makers' official catalogues (operating temperature, pressure, etc.). Shows, with sources, parts used outside their specs or close to the limits.
Part-number mismatches found
Finds where the drawing and the parts list give different part numbers. Example: “M-H5-4” on the drawing, “M-5H-4” in the parts list. Helps prevent wrong orders.
Fitted to your conditions
From temperature and environment, shows checks specific to that drawing. Example: water left in piping below freezing.
Precise findings
Not general points that fit any drawing, but precise concerns about that drawing.
Four viewpoints
Lists concerns on fabrication, assembly, maintenance and strength.
Shows the basis
Shows the basis from the drawing for each finding, and also flags parts that could not be read and parts whose specs could not be confirmed.
Report output
Results can be put together in an A3 report.
Use it as a team
Credits and review results are shared with the colleagues you invite. Administrators buy credits and manage members.
RESULTS
What you can expect
Design
Shorter design reviews
With concerns found before the review, review time goes to checking and deciding.
Design
Fewer part-selection errors
Notice overlooked specs or a wrongly chosen model before you order.
Start-up
Less rework at start-up and modification
Fewer remakes and re-orders during fabrication and assembly, and fewer problems early in start-up can follow.
Operation
Easier to maintain, longer-lasting equipment
Noticing parts that are hard to inspect or replace, or unsuited to the operating conditions, can lead to less maintenance work and less early wear of parts.
Operation
Higher equipment availability
Fewer concerns at the design stage lead to equipment that stops less.
People
Engineers grow
Reading findings and their basis is a chance to learn many viewpoints.
Effects vary with how it is used and with the equipment. No numerical effect is guaranteed.
COST
Cost merit (estimate)
Premise: an engineer's cost of about ¥5,000 per hour (assumption)
Assumptions of this estimate (open to see)
- Annual income of a mechanical design engineer: ¥6.59 million (job tag, Ministry of Health, Labour and Welfare; Basic Survey on Wage Structure, 2025). job tag (mechanical design engineer, in Japanese)
- Working hours per year: about 1,944 (162 per month; same source).
- The company's cost (social insurance, equipment and the like) is taken as about 1.5 times the income, about ¥5,000 per hour (¥6.59 million × 1.5 ÷ 1,944 h ≈ ¥5,085).
- The times in ① to ③ are assumptions from designers' experience, not measurements.
- ④ and ⑤ are examples of "when one case is prevented"; they are not always prevented.
- This software costs 10 cr per drawing page up to A3 (¥1,100 including tax). An attached parts list is included in the drawing's price. Prices follow Review AI's latest price list.
| Situation | Assumption | Cost if done by an engineer | Cost with this software | Cost merit |
|---|---|---|---|---|
| ① Looking for oversights before the drawing check | The drawing check takes 1 hour less per page | ¥5,0001 hour | ¥1,100per drawing page | about ¥3,900per drawing page |
| ② Checking the specifications of purchased parts | 10 models looked up in catalogues at 10 minutes each (100 minutes) | about ¥8,300100 minutes | Included in the drawing's price (¥0 extra) | about ¥8,300per drawing page (10 part models) |
| ③ When one correction after release is prevented | Correction, re-release and approval: 2 hours of design + 1 hour of checking | ¥15,0003 hours | ¥1,100per drawing page | about ¥13,900per correction avoided |
| ④ When one error found after machining is prevented | Remaking the part (machining, material, lead time) + correcting the design | ― | ¥1,100per drawing page | Tens of thousands of yen or moreper error avoided |
| ⑤ When a part with too short a life is reselected before release, or one equipment stop caused by a design error is prevented | Part replacement, loss from the stop, recovery work | ― | ¥1,100per drawing page | Hundreds of thousands of yen or moreper stoppage avoided |
Rows ③–⑤ are rough estimates for the case where a finding from the review prevents that one problem. Prevention is not guaranteed.
This is an estimate. The time saved is an assumption from designers' experience, not a measurement. It does not always find oversights and does not replace the drawing check.

COMPARISON
Compared with general AI
| Item | General chat AI | MECHOWL DESIGN REVIEW AI | Benefits |
|---|---|---|---|
| Share of findings specific to the drawing (excluding general points) | 59% | 95% | General points that fit any drawing are left out, so you can focus on what to verify on that drawing |
| Amount of text you check (per drawing) | About 5,800 Japanese characters | About 2,500 Japanese characters (about half of the chat AI's) | You can finish checking in less time |
| Cross-check of part specs (operating temperature, etc.) | Not cross-checked | Every part it could cross-check was judged correctly | Less work looking through catalogues one by one, and fewer spec oversights |
Measurement conditions
MechOwl's own survey (8 November 2026). Compared with the free version of a general chat AI. Evaluated on 3 publicly available equipment drawings that were not used for tuning. This software was given the drawing and the operating conditions, and the chat AI the same drawing and the parts list; each was asked once for a check before design review. Each “drawing-specific finding” was judged one by one by a MechOwl engineer. The share of specific findings counts independent findings and does not include the minor checks this software groups into one. The amount of text is the number of characters in the findings and improvement suggestions. The spec cross-check was compared with answers MechOwl prepared in advance (9 items); one item not yet in the catalogue at the time was shown as “cannot be confirmed” and has since been added. These are results on a small number of drawings and do not guarantee the same results on every drawing.
SECURITY
Security: compared with personal chat AI
| Item | Personal chat AI | MECHOWL DESIGN REVIEW AI |
|---|---|---|
| Use for AI training | By default, conversations may be used for training. To stop it, each user has to change the setting themselves. | No setting needed. Data sharing for training is turned off in the operator's settings. The provider states that API data is, in principle, not used for training. |
| Settings that vary by employee | If an employee forgets to change the setting, drawings they enter may be used for training. | The same handling, whoever uses it. |
| Storage of drawings | Kept in the conversation history until the user deletes them. | The original drawing is deleted automatically 24 hours after the review ends. The page images shown with the results are kept as long as the results, and can be deleted at any time. |
How personal chat AI handles data is based on the providers' public documents (checked on 8 November 2026). Business plans and APIs handle data differently. The AI model provider used for the analysis keeps data, normally for up to 30 days, to monitor misuse (it may be kept longer, for example where the law requires it). The provider states that API data is, in principle, not used for training.
