For DFMEA reviewers
Catch the DFMEA mistakes your reviewers miss
Empty Prevention Controls on Sev-10 rows. Vague "Bad design" causes. Supplier-blame in places it doesn't belong. Specwarden catches all three in seconds — and 60+ other audit-grade checks.
How it works
Upload your DFMEA
Drop in your spreadsheet — .xlsx, .xls, .csv, or .docx. Specwarden detects AIAG-RPN or AIAG-VDA format automatically. No configuration.
Review runs in under 60 seconds
7 deterministic rule checks run first, then Claude Sonnet reads every row for supplier-blame causes, vague language, and missing rationale.

Why choose Specwarden for DFMEA
7 rules
always run — even if AI degrades
Empty fields, out-of-range S/O/D ratings, wrong RPN arithmetic — 7 hard-coded checks run on every review. You always get a baseline, even if Anthropic is down.
60+
audit-grade checks per review
Beyond the 7 rule checks, the AI reviewer covers supplier-blame causes, vague language, missing rationale, and post-action validation — the checks senior reviewers do in hours.
Zero
files stored server-side
Your DFMEA is parsed inside the request, then immediately discarded. Findings are delivered to your browser and stay there. We store counts and metadata only.
What we catch
Tier-2 supplier-blame detection
The most-flagged audit failure: "supplier delivered bad parts" written as a design cause. Specwarden distinguishes design-spec gaps from supplier execution failures.
AIAG-RPN and AIAG-VDA auto-detected
Bring your existing 10-column AIAG sheet or the 16-column AIAG-VDA Handbook format. Specwarden detects which standard you're using and applies the correct rule set.
Deterministic rule floor — always runs
7 hard-coded rule checks (RPN arithmetic, field completeness, S/O/D range validation) run on every review regardless of AI status. You always get a baseline — even if Anthropic is down.
Built for engineering teams reviewing high-stakes technical documents.
Workflow proof
Reviews engineering documents against risk and compliance criteria
Use-case proof
Designed for FMEA, specs, quality checks, and design review workflows
Beta proof
Private beta feedback from technical reviewers and operators
Post-action closed-loop validation — included on all plans
AIAG-VDA §2.6.3 requires verifying that post-action revised ratings are populated when due. Specwarden checks that revised S/O/D values are filled in after the target date passes, that revised RPN arithmetic is correct, and that Severity hasn't been silently reduced (Severity is design-intrinsic — engineering actions reduce Occurrence and Detection, not Severity).
