Who it’s for

Board, hardware, firmware, and apps engineers who today use Excel + Ctrl+F on datasheets when choosing parts. Built by Mathuranathan Viswanathan (GaussianWaves).

The pain (why this exists)

Part selection is still mostly manual. You open a 50–400 page manufacturer PDF, find electrical / absolute-max / timing tables, then check those numbers against your board limits (rail budget, enclosure temperature, drive current, radio constraints). Common problems:

  • PDF search is incomplete: finding “VCC” or “Iq” with Ctrl+F often misses footnotes, test conditions, and the difference between recommended operating range and absolute maximum.
  • Limits and datasheet values live in different places: board limits sit in Excel; part values sit in a PDF. Copy/paste mistakes and outdated rows are common.
  • Hard to show where a number came from: design reviews ask for the source page, and keeping consistent citations is difficult.
  • Comparing several candidates is slow: checking 2–6 parts against the same design budget takes hours and it is easy to miss a hard fail.
  • Datasheets often cannot leave the company: uploading unreleased or NDA PDFs to a third-party AI site is usually not allowed.

How SpecsCore solves it

Your limits are the source of truth

Paste or upload board targets. SpecsCore does not invent industry defaults.

Matrix with citations

Row-by-row comparison plus Page / Section links that jump in a local PDF preview.

Local-first privacy

PDFs stay on your PC. Bring your own Gemini / OpenAI / Anthropic key — no datasheet middleman cloud.

Cross-compare & scope

Load several candidates against the same limits; for long manuals, pick Electrical / Absolute Max / radio sections.

How it works

  1. 1 Slot 1 — Datasheet: load a manufacturer PDF (or the built-in NE555 sample).
  2. 2 Slot 2 — Design limits: paste or upload your board targets (CSV / Excel / table).
  3. 3 Run: get a compliance matrix; click Page / Section links to jump in the local PDF preview.

Privacy

  • PDF files stay on your computer and are parsed locally.
  • Your API key stays on this device (Gemini, OpenAI, or Anthropic — you choose).
  • On Run, only the text you selected (plus design limits) goes to your provider.
  • SpecsCore does not operate a middleman cloud for your datasheets.
We’re gathering engineer feedback (free evaluation).

After you try the Windows build (about 15–20 minutes with the sample), please reply with:

  1. Did install + first Run make sense?
  2. Would this help vs Excel + Ctrl+F on datasheets — yes / no / maybe, and why?
  3. Anything broken or missing that would stop you from using it again?

Send feedback to [email protected] · Use public datasheets only.

Requirements

Windows 10 or 11 (64-bit). WebView2 is installed automatically by the SpecsCore installer if missing. You need an API key from Google Gemini (easiest), OpenAI, or Anthropic to click Run — or explore the UI with the sample without a key.
