01The challenge

A manual slog on every side — and easy to fake.

Conference organizers hand out certificates by the thousand — each one designed and exported by hand, emailed one at a time, with no way for anyone to confirm it's real. Recipients can't prove their certificate is authentic; organizers can't catch forgeries; and nobody has a record of what was issued to whom.

The manual way
  • Design and export each certificate by hand
  • Email them out one at a time
  • No way to prove a certificate is genuine
  • Forgeries impossible to catch, no record
With Scholarcert
  • Bulk-generate personalized PDF + PNG in one run
  • Auto-deliver — immediate, scheduled, or manual
  • QR verification confirms authenticity instantly
  • Tamper-proof IDs, full audit trail + analytics
02What we built

Not a feature — a whole platform.

A complete, production-grade SaaS. Organizers set up conferences and editions, add recipients by dashboard, CSV, or API — and Scholarcert generates personalized, QR-verified certificates and delivers them automatically. Bind any element to a data field like {{full_name}} and it fills from the recipient list. Every certificate has a unique ID and a public verification page, so authenticity is one scan away. Built across 13 phases, live and running in production.

03How it works · the certificate lifecycle

From setup to a certificate anyone can verify — in five stages.

01 · SET UP

Create & add recipients

Set up a conference and edition; add recipients via dashboard, CSV import, or the API.

02 · DESIGN

Template, or AI convert

Upload an HTML template — or let Claude's vision AI turn a PDF into an editable one.

03 · GENERATE

Bulk PDF + PNG

Puppeteer creates personalized files, each with a unique ID (SC-2026-A7X3K) and QR.

04 · DELIVER

Send & track

Immediate, scheduled, or manual — emailed via Postmark with open/bounce tracking.

05 · VERIFY

Prove it's real

Anyone scans the QR → a public page confirms the certificate is genuine, no login.
