Local AI
On-device AI that organizes your day

A diary app powered by on-device AI
Lockeep
Speak it into existence. Let every reunion find its way back.
Capture life with voice, text and photos. Lockeep uses on-device AI to organize your voice notes, journal threads and reunions, resurfacing the moments that matter when the time is right.
Features
Recording stays simple. Looking back feels natural.
Lockeep brings on-device AI organization, journaling, memory search and sharing into one calm flow.
Voice
Say it, and it becomes a diary
Speak your everyday moments out loud and Lockeep organizes them on-device into a draft worth rereading.
Search
When remembering, just search
Find a day, a person or a moment quickly by time, place and keywords.
Reunion
Important memories will find you again.
Recording is not just for archiving. Lockeep keeps time, place and content clues, and brings meaningful memories back when you look back later.
- Organize reviewable timelines from your journals and photos
- Surface memories naturally on Home, widgets and detail pages
- Never automatically upload your diary content to a developer server
Privacy
Your diary is your private asset.
Lockeep defaults to local storage and on-device processing. Diary text, image attachments, voice transcriptions and AI results stay on your device by default.
Local first
The current version has no developer-side accounts, cloud sync or cloud AI inference.
No ad profiling
No third-party ad SDKs, and your diary content is never shared for ad targeting.
Apple-managed subscriptions
Purchases, renewals, cancellations and refunds are handled by your Apple account and StoreKit.
Details
What you record can be shared too.
