Three ways a job goes wrong: you quote blind, the part gets rejected, the dispatch slips. Send the drawing — or the 3D model — and SpecReview prices it on your own rates, shows where it will fail inspection before you cut metal, and writes the quality and outsourcing paperwork, so nothing comes back and nothing waits.
Where the part is likely to be rejected — tricky tolerances, GD&T you could misread, features that will fail inspection
2D + 3D
Whatever you receive
A PDF drawing, a STEP model, or both. SpecReview reads the drawing you actually get — and tells you honestly what a model alone cannot confirm
₹/piece
Should-cost + tooling
Material, machining, setup and tooling built up on your own rate card — so you quote from numbers, not gut feel, and know your floor before you negotiate
Paperwork
Quality + outsourcing
Inspection plans, draft PPAP, and complete RFQs for plating, heat treatment and NDT — the documents that win OEM and export work
What you get
Quote it right. Make it right. Prove it right — from one drawing.
Upload a customer drawing as PDF. Every output is grounded in what's actually on the drawing — not generic advice. Each downloads as a professional document you can share with your customer or keep on file.
01 · AUDIT
Drawing Audit
Before you quote, know if the drawing is complete enough to manufacture from. Scores 100 points across 6 categories. Flags gaps that will cause rejections or rework — before they cost you.
1 credit
02 · BOM
BOM Extraction
For assembly drawings — pull the full parts list, separate what you'll fabricate vs what you'll buy in, and see which items will drive cost. Faster than reading the drawing line by line.
2 credits · assembly drawings only
03 · SHOULD-COST
Should-Cost + Tooling
Build your quote on geometry, not gut feel. AI selects machines, estimates cycle times, and calculates your cost floor. Now includes tooling cost estimation — die, mould, jig, fixture, gauge — with amortisation at 500 / 2,000 / 10,000 pieces. The number SMEs most often forget to quote.
3 credits · your rates, your numbers
04 · DFM
DFM + Rejection Risk
Spot features that will make this part expensive or risky — tight tolerances, thin walls, difficult weld access. Now includes Rejection Risk Predictor: the top 5 features most likely to fail at customer incoming inspection, with probability and specific prevention controls.
2 credits
05 · QUALITY
Quality Plan + In-Process
CTQ register, IS 2500 sampling, FAI checklist — plus a new In-Process Inspection Plan: the shop-floor traveller card listing what to check, with what instrument, at what frequency, after each manufacturing operation. Prevents defects moving forward before they get expensive.
2 credits
06 · VA/VE
VA/VE + Material Substitution
Up to 10 cost-out ideas across 8 levers. Now includes a dedicated Material Substitution section — alternate IS/ASTM grades that meet the same functional requirements at lower cost, with ₹/kg savings, required process changes, and whether OEM approval is needed.
2 credits
07 · RFQ
Supplier RFQ Generator
Auto-generate a formatted RFQ to send to your sub-vendors. Two modes: Full Drawing RFQ (complete technical RFQ for the whole part) or Bought-out Parts RFQ (individual RFQs for each purchased item in the BOM). Includes commercial terms, PPAP level, FAI requirement — standard Indian automotive practice.
1 credit

One wrong quote costs more than a year of SpecReview.
You quote ₹4,200 because the drawing looked straightforward. You win the job. Then you discover a tight tolerance you missed requires a fixture you don't have, and the surface finish demands a process you don't run in-house. Actual cost: ₹5,800. Loss on the job: ₹1,60,000. SpecReview 6-Month pack: ₹24,999.
Numbers are illustrative. Your actual savings depend on your rates, job sizes, and how often you encounter complex drawings. SpecReview gives you indicative analysis — verify before committing to a quote.

Answers
Questions manufacturers ask before they quote.
What is SpecReview?
SpecReview is an AI tool that reads a 2D engineering drawing (PDF) or a 3D STEP model and tells an Indian SME manufacturer where a part is likely to be rejected, what it should cost to make, and produces the inspection and PPAP paperwork the customer expects — before any metal is cut.
How does SpecReview analyse a 2D engineering drawing?
Upload the drawing as a PDF. SpecReview extracts the dimensions, tolerances, GD&T, surface finish, material and notes, checks the drawing for missing or conflicting information, and returns a manufacturability review, rejection-risk flags, a should-cost estimate and an inspection plan.
Can SpecReview work from a 3D STEP model instead of a 2D drawing?
Yes. You can upload a 2D PDF, a STEP model, or both. With a STEP file only, SpecReview works from the extracted geometry and assumes ISO 2768 general tolerances; every output is tagged as spec, geometry or assumed so you know what came from where. PPAP and quality documents need a real drawing and stay limited until one is added.
What is should-cost analysis and why does it matter?
A should-cost estimate breaks a part into material, machining or process time, tooling and secondary operations to show roughly what it should cost to manufacture. It lets you quote with a real margin instead of guessing, and spot when a customer’s target price is unrealistic.
How does SpecReview help me get a part right the first time?
SpecReview flags the tolerances, features and callouts most likely to cause rejection or rework, explains why each one matters and what to do about it — so problems are caught at the quoting stage, not after a batch is already machined and sent for inspection.
Does SpecReview generate PPAP and inspection documents?
Yes. From a drawing it can build a layout inspection plan, a quality plan and PPAP paperwork and export them as PDF or Word. Export-order paperwork such as the commercial invoice, packing list and certificate of conformance is also available. Company letterhead and the export-documents module are on the paid plans.
How much does SpecReview cost?
SpecReview is pay-per-drawing using credit packs, not a subscription. New accounts get 15 free credits. Paid packs are ₹4,999 for 100 credits (valid 1 month), ₹24,999 for 400 credits (valid 6 months) and ₹46,999 for 1,000 credits (valid 12 months). Credits roll forward within their validity and do not auto-renew.
Is my drawing data kept confidential?
Drawings are used to generate your own analysis and are not shared with other users. A security and data overview is published on the site, and the team can answer specific confidentiality questions at support@specreview.in.
Who is SpecReview built for?
SpecReview is built for Indian SME manufacturers and job shops — machining, sheet-metal, casting and fabrication shops that quote against customer drawings and need to quote faster, avoid rejections and produce quality paperwork without a large engineering team.
