Show HN: Vanta – Markdown notes for iPhone with on-device AI

Vanta is a Markdown notes app for iPhone, built around on-device AI organization and GTD (Getting Things Done).

I use Obsidian with Claude on desktop, and wanted a similar but automated flow on mobile. This started out as an experiment with Apple's local Foundation models which turned out to be genuinely useful for me. The local models are used to clean up messy dictation, format Markdown, and categorize your inbox using GTD principles.

Maybe one day it'll do your todos for you too :)

Import and sync your existing Obsidian vault on Github, or start with a new one. iCloud Drive sync is included.
