AI Product MatchingAI Product Matching › Datasheet matching
How do you match technical products by their datasheets?
Extract the key specifications from each datasheet or product page, such as dimensions, voltage, material and part numbers, normalise the units, and compare the specifications instead of the titles. Match on manufacturer part number first; use specification similarity for equivalents and replacements.

Quick picks
If items have part numbers
MPN lookup
Exact and fast.
For equivalents and substitutes
Spec comparison
Weighted on the specs that matter.
For scraping product specs from shops

AI scrapers that return the fields you name.
Compared
| Step | What happens | Tools |
|---|---|---|
| Extract | Pull specs from PDFs and pages into fields | PDF parsers, LLM extraction, scrapers |
| Normalise | Convert units and formats | Rules and unit libraries |
| Match identifiers | MPN, UPC, supplier code | Exact lookup |
| Compare specs | Score how closely key specs agree | Weighted rules or a classifier |
| Map to your SKUs | Link matched items to your catalogue | Your PIM or ERP |
Which specs to compare
- Identity specs
- Part number, series, generation: these decide “same product”.
- Fit specs
- Dimensions, threads, connectors: these decide “will it fit”.
- Performance specs
- Power, capacity, rating: these decide “equivalent or better”.
Frequently asked questions
What is AI datasheet matching?
Using AI to extract specifications from datasheets and product pages, then matching products by those specs and part numbers rather than by title.
How do I map UPC and MPN to my SKUs?
Build a lookup table from your catalogue's UPCs and MPNs, normalise the codes (leading zeros, separators), and match incoming items against it before trying spec similarity.
Can LLMs read datasheets?
Yes. Language models can extract fields such as dimensions and ratings from PDFs and pages, but check a sample, as they can misread tables.
Why not just match on titles?
Technical titles are inconsistent and often omit the specs that matter, so two very different parts can have similar names.
