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. The calendar shows what the Calendar API returned, period. No write tool, on purpose. Email

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.
