This is a submission for the Postmark Challenge: Inbox Innovators.

What I Built

Postmarks (naming things eh...) is a personal link bookmarking service.

Users interact with the service via email, obviously, and can email a link to be bookmarked, email to list their links, and email a query to search for links via content. Each user get's their own database, courtesy of Cloudflare Durable Objects.

It's barebones, but it was a fun little project.

Demo

Screenshots are below - it's email, so not much to demo. I've redacted the inbound email address to protect my Postmark free account email limit, but if the judges reach out I'll share the email address to interact with the app.

How I Built It

The app makes use of Postmarks Inbound and Transactional streams, to interact with a Cloudflare Worker, backed by Vectorize and Durable Objects. The smarts are provided by Workers AI, via the Vercel AI SDK.

A full step-by-step tutorial is available on the GitHub repo.
