A Chrome extension I co-founded so teams could leave comments directly on a webpage. Tag an element, leave a note, and bring a teammate back to the exact spot.
A screenshot can show a problem, but the conversation often drifts away from the page. TagU kept feedback beside the element a person was talking about: a bug, a design change, or an instruction.
Teammates could leave comments and sticky notes, tag each other, and return to the relevant location from a browser notification.
I worked on the application architecture and navigation, then injected React components into webpages through Manifest V3. The extension and the injected interface ran in separate JavaScript contexts, so I built the messaging between them.
I implemented email, Google, and Facebook authentication with Supabase, designed the data model, and added database functions and triggers. My work included comments, team notifications, the tag list, and urgency filtering.
I built the landing page and Stripe payment flow, including seat-based pricing for a lifetime offer. I shared progress publicly, asked for design feedback, and invited people to test the beta.
We worked asynchronously across countries. I organized tasks and recorded explanations of complex code so teammates could pick up the work. I also prepared the extension for Chrome Web Store beta review.
On June 19, 2023, I shared that TagU had 37 waitlist signups and had sold four lifetime deals. It was my first build-in-public product to receive a payment.
The website is no longer available. This page keeps the product story and my work on it in one place.
