Narafy is a tag-first notes app that is being rebuilt from scratch. The idea is simple: write a note once, tag it however suits you, and find it again in seconds — with AI helping organise, connect and answer from your notes across phone, desktop and web.
Rather than forcing folders or hierarchies, Narafy lets you attach as many tags as you like and then retrieve notes instantly by any combination of them.
The relaunch is designed around the idea that your own notes should be able to answer questions, not just sit in a list.
A single app is planned for iPhone, iPad and Mac, alongside Android, Windows and browser versions, so the same notes follow you everywhere.
Independent 'Classic' and 'Glass' looks are offered so the writing surface can match your taste, and writing a note is intended to feel pleasant in itself.
