Glean · 亘乐日记
Jot down every day
Jot down a sentence, a thought, a fragment of life. AI daily summaries and weekly/monthly reviews weave scattered notes into your own trajectory — proof that you lived it.
Glean (Chinese name: 亘乐日记) is a lightweight AI journaling app: jot down a sentence or a thought, and AI generates daily summaries and weekly/monthly reviews. All data stays on your device. Runs as a WeChat Mini Program, bilingual (Chinese/English), core features free.
Core experience
Recording is just the start — being seen is the point.
Quick notes
A line, a thought — jot it down. No templates, no formatting pressure. Open and write; never face a blank page.
AI reflection
Start a focused conversation about any entry; AI polishing and daily summaries are there when you want them. AI is a mirror for reflection, never a ghostwriter.
Plant companionship
Daily records nourish your plant. Miss a day and it pauses — never withers. Harvest oxygen and fruit, and grow a tree into a garden.
Weekly & monthly reviews
Grid-style reviews appear right in your timeline, with AI summaries, long-image sharing and follow-up conversations.
Screenshots

Design philosophy
What we refuse to build matters as much as what we build.
Zero pressure
No streaks, no leaderboards, no anxiety marketing. When you're away, the app simply says: take your time, I'm here.
Only up, never down
Entries, oxygen and badges only ever increase — once companionship has happened, it's a fact.
No social features
A diary is private: no likes, no comments, no feed. Consistency needs no audience.
Data sovereignty & privacy
- All diary data lives on your device — no accounts, no server-side business database.
- Export anytime: plain JSON to your favorites or file helper — your data stays readable to you.
- Cloud backup is a channel you opt into, end-to-end encrypted (AES-256) by default; passwords and keys never leave your device.
- AI calls are transparent and controllable: bring your own key (BYOK); text is only sent when you trigger it.
FAQ
Six frequent questions about AI, privacy and usage.
Does AI write my diary for me?
No. AI is a mirror for reflection, not a ghostwriter: polishing, daily summaries, reviews and focused dialogs all build on what you have already written.
When does AI read my diary?
Only when you explicitly trigger it (or enable the auto daily summary). Supports BYOK — you choose the AI provider.
Where is my data stored?
Entirely on your device — no account system, no server-side database. Only weather lookups and AI calls touch the network.
Is cloud backup safe?
Yes, and it is opt-in: zero-knowledge end-to-end encryption (PBKDF2 key derivation, AES-256-CTR, HMAC), passwords and keys never leave your device; keeps the latest 3 copies.
Is it free?
Core features are free: journaling, AI summaries, reviews, plant nurturing and badges.
