About Daily Diary

What is Daily Diary?

Daily Diary is a private journalling app that helps you capture the moments, thoughts, and conversations that make up your day — then turns them into something worth keeping.

You can jot down quick notes by typing or speaking, and at the end of the day let AI help you weave them into a polished diary entry. You can also reflect on your day with Lumi, your AI confidant — she listens, gently reflects back what you share, and follows your lead.

Who built this?

Daily Diary was built by Alvin Teo, as a personal project that grew into something shareable. It's an experiment in using AI to make reflection easier — not to replace journalling, but to lower the barrier to starting.

Your privacy

Your notes are yours. The admin cannot read your diary entries or notes — by design. AI processing happens via Anthropic's Claude API, and nothing is stored beyond what's needed to generate your response.
