Would love to hear how you manage notes of org and md files, what packages you recommend and how to combine LLM models if possible.

The problem started small: our kid turned to 7 and started school, and suddenly we had a flood of emails and paper letters with dates in them class activities, appointments. Every one of them meant someone had to open the email, read it, and manually type an event into our shared calendar. We kept missing things or duplicating them, "did you add the swim class?" "I thought you did."

I looked for a tool that already did this and didn't find one that fit, so I built one myself in my spare time, called Mailendar. It's live at mailendar.app, iOS app is out too. Built it for our own family first, now sharing it more broadly.

What it does: you forward the email (or snap a photo of letters) to Mailendar, and it reads the event details and adds it to a calendar you and your family subscribe to, right inside whatever calendar app you already use, Apple Calendar for example. No retyping, no separate app to check.

Stack: FastAPI backend, Next.js frontend, Flutter for the iOS app, Postgres on Supabase, deployed on Fly.io. Claude Code has been my main coding agent for the implementation, and I used OpenSpec to keep the design and test requirements from drifting as I built.

What I'd love feedback on

• Does "forward an email, get an event" sound like something you'd actually trust and willing to do?
• If you've built something with a similarly narrow, specific use case, how did you find your first users outside your own circle?
• Anything that sounds off, confusing, or missing from how I've described it here? Happy to answer anything about the build, the stack, or the spec-driven workflow.

Thank you so much!
