Lucent

Notes, tasks, and an AI assistant with actual hands.

Most note-taking apps extend a generous invitation to choose any two of three virtues: the beautiful one, the private one, or the intelligent one. Lucent politely declines the bargain — and happens to be made of glass.

THE SHORT VERSION

A notebook that remembers.
A to-do list with teeth.

Everything you write is sealed in an encrypted database that never departs your device. The assistant living inside it is not a chat box with opinions — it can tidy your notes, run your errands, rename your files. And before it touches a single byte, it lays the whole plan out in front of you: what, where, why — every arguable field editable. You nod; only then does it write.

🤲

An assistant with hands

Create, edit, archive and delete notes; manage tasks; search with a real filter language — it does these things itself instead of merely suggesting them.

🔒

Paranoid-grade encryption

SQLCipher database, individually locked attachments, an app lock with a genuine brute-force policy. Backups are a single password-protected file that fits in your pocket.

🧠

Your model, your call

Plug in any cloud model you pay for — or import a .gguf and let llama.cpp run on your own silicon. Offline works. Prefer no assistant at all? Switch it off; the notes lose nothing.

🦷

Tasks with teeth

Subtasks, priorities, repeat schedules. Type "next Friday at 6" and it becomes a real timestamp with a real alarm — not a pretty sentence.

🕰️

Notes with memory

Every meaningful edit is snapshotted, so a confident 2 a.m. rewrite can always be undone by morning. Bidirectional links, templates, doodles — the works.

🫧

Made of glass, unashamedly

A living gradient drifts behind frosted panels. Eight style families, Monet-tinted themes — on Android 12+ it even borrows your wallpaper's palette for the day.

ONE CODEBASE, TWO HOMES

In your pocket. On your desk.

One product with a single shared heart: whatever you capture on one side, the other side understands. Android and Windows editions, each built by pressing a single button on GitHub.

PRIVACY

Nothing to "promise" —
because nothing leaves

Don't export, don't show a model, and not a single byte departs your device. Privacy that is structural, not merely promised.
