Sometimes you just need someone to listen. Lisner is a voice-first thought journal built for the way busy, creative, and neurodivergent minds actually work. A thought hits you mid-run, mid-meeting, mid-shower — tap once, speak, and it's saved. No typing. No friction. TAP. TALK. DONE. Hold the record button. Speak freely. Lisner transcribes your voice entirely on-device — a state-of-the-art AI model built into your iPhone. Your audio is never recorded, never stored, and never sent anywhere. SMART, ON-DEVICE AI An AI headline summarizes each thought in one crisp line so you can scan your whole week at a glance. If a headline ever gets stale after you edit a thought, Lisner silently fixes it in the background — automatically. SPEAKS YOUR LANGUAGE Record in any of 99 languages. Lisner detects your language automatically and translates everything into English before saving — no setup required. ICLOUD BACKUP — YOUR THOUGHTS, EVERYWHERE. Lisner seamlessly syncs your thoughts to iCloud. Restore everything on a new device, instantly. You stay in control — iCloud backup is on by default and can be turned off anytime from the Permissions screen. COMPLETELY PRIVATE BY DESIGN • Audio is never stored — only the transcript is kept • Thoughts live locally on your iPhone using Apple's SwiftData • iCloud sync uses Apple's encrypted CloudKit infrastructure • No ads. No tracking. No selling your data. • Delete your account and every thought — on-device and in the cloud — instantly, anytime. BUILT FOR YOUR BRAIN Soft colors. No streaks. No guilt trips. Lisner is a calm, distraction-free space to offload whatever is in your head so you can stop carrying it around. A 30-day Recently Deleted bin means nothing is gone for good until you choose. The best thoughts are the ones you don't lose. Lisner makes sure you never lose them. https://lisner.ai/terms.html
