Email and productivity assistant for Google Workspace that answers with interactive widgets you approve.
u/narin_luangrath · Reddit
Solo-built an email agent where the AI literally cannot act on its own — the architecture is the pitch Building SmolMail ( https://smolmail.com ) solo for a few months. Two build decisions turned out to be the whole product: Widgets over prose. Every answer renders as a real component (calendar grid, email list, editable forms) and the model only picks the props — so the UI can't hallucinate.

First things first: On the landing page, click on the "demo" link below the Hero section to try it without jumping any hoops ** I'm a long-time Basecamp user and satisfied with its overall functionality. Of course, there are many things that can be improved but that is not the point of this post. *Background* Basecamp lets users create "Projects". These projects are isolated workspaces that contain: members, todos, chat, files, message board, and calendar, etc. My issue was with the scattered calendars. Because I (and every other Basecamp user) creates a dedicated project for different scope of work, even if it is for the same client. For example, at any given time, I may have 4 projects for client-X and 3 projects for client-Y. *My pain point* I have experienced that most clients (especially the decision-makers) do not use Basecamp as often as we--the agency folks use it.

I’ve been using Windows as my daily use lately despite I have been using Mac/Linux for a long time, but I keep running into all sorts of issues, so I’ve been fixing them vibe-coding with Claude. I’m gonna dump all that stuff on This blog is fully automated with Claude Code, from coding all the way to reporting. It’s nothing special—anyone could do it—but it’s actually pretty fun once you try it. The only annoyed is that it burns through tokens like crazy. Most of the tips are pretty interesting, so I hope you find them useful.
