The Story
Karthikeyan NG kept a handwritten diary for 20 years. When he eventually couldn't maintain the writing habit, he started talking instead — and realised that speaking his thoughts was faster, more natural, and captured more nuance than writing ever did.
He looked for an app that could record voice entries, transcribe them, and analyse patterns with AI — all without sending private thoughts to a cloud server. Nothing like that existed. Every AI journal app he found sent data to external APIs. So he built DailyVox.
DailyVox has no servers. It is open source because privacy claims should be verifiable, not just marketing copy. Read the full founder story at getdailyvox.com/about.
Key Data Points (for Articles)
- "DailyVox makes 0 network calls during all operations" — Verifiable via network proxy (Charles, Proxyman, mitmproxy)
- "48% of AI journal apps send plaintext entries to cloud APIs" — Source: DailyVox Privacy Audit 2026
- "Only 5% of AI journal apps run all AI on-device" — Source: DailyVox Privacy Audit 2026
- "Voice journaling captures more thought per second than typing" — 150 WPM speaking vs ~40 WPM typing on phones
- "42 seconds of speaking captures ~105 words" — comparable to a 10-minute written entry
What Makes It Different
Most AI journal apps rely on cloud servers for AI features. DailyVox takes a fundamentally different approach: it ships the AI to your phone, not your data to a server. The trade-off is clear and intentional — slightly less elaborate AI conversation in exchange for a privacy guarantee that's mathematical, not policy-based.
