From drawing to
certified spec.
CertX reads your technical drawings and balloons every inspection characteristic — dimensions, tolerances, threads, surface finish — into an audit-ready ISO inspection sheet. Minutes, not hours.
Diaphragm valve actuator
Ballooning by hand is slow — and one miss is a finding.
Transcribing a busy drawing means squinting at every callout, copying tolerances into a table, and hoping nothing slipped. CertX does the reading; you do the deciding.
Manual ballooning
One engineer, a highlighter, and a spreadsheet.
- × 2–4 hours per multi-view drawing
- × Tolerances and GD&T retyped by hand
- × Missed characteristics surface during the audit
- × No trace back to where a value came from
Automatic extraction
The engine reads, balloons, and tabulates. You review.
- ✓ A ballooned inspection sheet in minutes
- ✓ Dimensions, tolerances, threads & finish captured
- ✓ Low-confidence items flagged for a human
- ✓ Every value links back to the drawing region
How CertX gets you to a certified sheet
Upload the drawing
Drop in a PDF or a scan. Multi-view, sectioned, detail callouts — CertX handles real shop drawings.
It reads & balloons
The engine detects each inspection characteristic, numbers it, and reads the nominal, tolerance and symbol.
Review & export
Approve the high-confidence items, check the flagged ones, and export your ISO 9001 inspection sheet.
Every kind of callout, captured
If it's an inspection characteristic on the sheet, CertX is built to find it and tabulate it.
Dimensions
Linear, diametral, radial and angular sizes pulled with their nominal value.
Tolerances & GD&T
Plus/minus limits, fits (H7/g6) and geometric symbols with datums.
Threads
Metric and imperial thread specs, pitch and class of fit.
Surface finish
Roughness callouts and finish symbols, read per face.
Weld & feature symbols
Weld symbols, chamfers and edge notes flagged as characteristics.
Notes & title block
Material, part number, general tolerances and revision from the block.
Read the drawing. Check the table. Sign it off.

Certified means accountable
EU data residency
Drawings and extractions are hosted in the EU (Supabase EU). Your IP never leaves Europe.
Full traceability
Each value links back to its region on the drawing — so an auditor can see exactly where it came from.
ISO 9001 export
Output an inspection sheet aligned to ISO 9001:2015 — as PDF, Excel, or a German Prüfprotokoll.
The maths, measured — not promised.
Ten real production drawings, timed end to end. 156 inspection characteristics. Here is what they cost by hand, and with CertX.
| Drawing | Points | CertX (measured) | By hand (est.) | Faster by |
|---|---|---|---|---|
| Drawing A | 6 | 11.5 s | ~24 min | ~125× |
| Drawing B | 10 | 15.9 s | ~30 min | ~113× |
| Drawing C | 10 | 17.4 s | ~30 min | ~103× |
| Drawing D | 13 | 18.5 s | ~35 min | ~112× |
| Drawing E · rev 1 | 13 | 19.3 s | ~35 min | ~107× |
| Drawing E · rev 2 | 13 | 44.3 s | ~35 min | ~47× |
| Drawing F | 14 | 21.0 s | ~36 min | ~103× |
| Drawing G | 16 | 28.2 s | ~39 min | ~83× |
| Drawing H | 20 | 28.2 s | ~45 min | ~96× |
| Drawing I | 41 | 61.1 s | 1 h 17 m | ~75× |
| Total · 10 drawings | 156 | 4 min 25 s | ~6 h 24 m | ~87× |
- Extraction times are measured on 10 real production drawings (6 to 41 characteristics each), timed end to end — total 265.4 s, average 26.5 s.
- The manual figure is an estimate: 15 min setup per drawing plus 1.5 min per characteristic. The honest range is roughly 4–10 hours for these ten; ~6.4 h is the midpoint.
- Labour rate: €4,500 gross/month ≈ €27/h over ~167 productive hours. Fully loaded with ~21% employer contributions it is ~€33/h.
- End-to-end and cost figures include human verification. A person still checks the drafted sheet — but verifies a finished document rather than building it from scratch.
- Accuracy is not yet formally measured. These savings hold only while extraction is good enough that checking beats redoing — which the evaluation set on real drawings is there to establish before any of this is quoted to a customer.
- CertX produces audit-ready inspection documents aligned to ISO 9001:2015 §8.4. It does not issue certificates.
