Source-linked extraction
Extracted specifications retain their page, sheet, table, or source text so reviewers can verify the record.
Engineering Datasheet Comparison
Compare Technical Datasheets Without Building Another Spreadsheet
SpecCore turns PDFs, spreadsheets, and vendor spec sheets into a structured comparison you can verify. Extract specifications, normalize compatible units, review uncertain matches, and trace every value back to its source.
Public access is not yet open. Join the waitlist for launch availability and product updates. Source files remain private, and SpecCore does not sell personal data.
The comparison problem
Technical comparisons get messy fast.
Supplier documents rarely use the same structure, labels, units, or level of detail. The resulting spreadsheet becomes another technical artifact that must be checked and maintained.
Specifications scattered across PDFs, tables, and spreadsheet exports
Equivalent requirements published under different field names
Inconsistent units that must be converted before evaluation
Manual copying into Excel and repeated checks against source documents
SpecCore handles the mechanical comparison work while leaving engineering judgment with the engineer.
Example comparison matrix
See the original value, the normalized value, and what changed.
Every comparison row keeps the source value visible beside the normalized result. Converted, equivalent, missing, conflicting, or low-confidence fields remain visible for review.
| Spec | A Original | B Original | A Normalized | B Normalized | Review |
|---|---|---|---|---|---|
| Supply | 4.5 to 28 V | 5 to 24 V | 4.5 to 28 V | 5 to 24 V | Overlap |
| Current | 125 uA typ | 0.16 mA typ | 0.000125 A typ | 0.00016 A typ | Converted |
| Isolation | 5 kVrms | 5000 Vrms | 5000 Vrms | 5000 Vrms | Equivalent |
| Temp range | -40 to 125 C | -55 to 105 C | -40 to 125 C | -55 to 105 C | Flagged |
Inspectable automation
The automation should be inspectable.
Deterministic normalization
Compatible units are converted with explicit formulas while every original value remains preserved.
Engineer confirmation
Uncertain field mappings and conditions remain visible for review instead of being treated as exact matches.
Missing data stays missing
Unavailable or non-comparable values are marked for review. SpecCore does not invent numbers to complete a row.
Engineering workflow
From vendor files to a reviewable comparison
Step 1
Upload
Add PDF, XLSX, or CSV supplier files to one comparison workspace.
Step 2
Extract
Read selectable text and tables while retaining source context.
Step 3
Confirm
Review uncertain field mappings, limits, and operating conditions.
Step 4
Normalize
Convert compatible values into consistent engineering units.
Step 5
Compare
See original and normalized values together in a structured matrix.
Step 6
Export
Prepare a reviewable output for engineering and purchasing workflows.
Industry coverage
Built for technical product evaluation
Semiconductor
Compare devices, RF components, sensors, packaging, process equipment, and fab specifications.
Aerospace
Review avionics, structures, materials, propulsion, fluid systems, and qualified components.
Oil & Gas
Normalize pressure, flow, temperature, material, valve, fitting, and equipment requirements.
Hydrogen & Clean Energy
Organize pressure, compatibility, purity, storage, flow, and balance-of-plant specifications.
Launch access
Join the waitlist to test it on datasheets you already work with.
Public access is opening in stages. Join the waitlist to receive launch availability and product updates, then evaluate SpecCore with a small set of representative files.
