Build a web app that designs and bulk-generates certificates. 1. Start with 10 editable certificate templates (course completion, employee recognition, student achievement, workshop, and camp), each with swappable color schemes. 2. Let the user paste a list of recipient names or upload a CSV with name, course, and date columns. 3. Preview each certificate live in the browser with the first recipient's data. 4. Use an LLM to suggest a one-line accomplishment phrase and design tweaks (color palette, border style, font pairing) based on the certificate type. 5. Render every recipient's certificate to a print-ready PDF at standard US Letter and A4 sizes, zipped for download. 6. Support a logo upload and a signature image upload, placed per template. 7. Add unique verification: each certificate gets a code and a public verification URL page so recipients can prove it is real. 8. Save designs to an account so organizations can reuse them each cohort. 9. Keep the flow linear: pick template, add names, preview, download.
