Ear Diary

Effortlessly turn what's heard and thought into a searchable automatic diary

Why Ear Diary?

Reflect on what was said and what was heard. Notice patterns, improve communication, or simply understand oneself better.

Ideas pop up while thinking aloud. Capture them without stopping to type or write. Easily find them later.

Build an archive of conversations, decisions, and thoughts. Searchable and under control, not scattered across apps.

Keep a written trace of important calls and discussions, without relying on clouds or third parties. Everything stays locally on Mac.

A minimalist approach to translation.

Philosophy

Radical Minimalism

Constrained strictly to dual-language translation. No bloated menus, no infinite language lists. Just two languages, optimized for speed.

Direct Translation

Designed to break the default cultural norm of relying on English as a third intermediary language. Communicate directly.

Context Optimized

Travelers and language learners usually only need two languages for extended periods. We skipped the 'all-in-one' trap to focus on utility.
