This is a submission for the Postmark Challenge: Inbox Innovators.
What I Built
Clause Clarity is a contract reviewer that works over email.
The idea is simple: send a contract PDF to your inbox address, and within a few seconds, you get a structured breakdown of the agreement. It tells you what’s inside the document, what’s missing, and what looks risky.
It’s built for freelancers, startup teams, and business folks who constantly deal with contracts but aren’t always sure what they’re signing. Clause Clarity helps make those decisions faster and a bit more confident.

How I Built It
Clause Clarity runs on Laravel with FilamentPHP handling the UI. Postmark takes care of inbound email and sends contract PDFs directly to a webhook. I use Spatie’s PDF-to-text to extract the text, then pass it to OpenAI (GPT-4) to review the contents.
Everything runs in the background as a job. Once the review is ready, the dashboard shows a clean report with a visual risk meter and clause-level feedback.

Working with Postmark
Postmark was very seamless to integrate. It took a few minutes to read the docs and get the inbound email feature working. I didn’t have to worry about polling inboxes or setting up anything complicated—just one webhook, and it was good to go.
