Brainstorm Mode

An interactive AI chat that remembers your conversation across sessions. Think out loud, get unstuck, or explore an idea — without sending a single token to the cloud.

Prefer a cloud model? Bring your own key. NoteItUP also supports:

Privacy isn't a setting. It's the default.

Your diary should be the one place that's truly yours. NoteItUP is built local-first, with cloud features that are opt-in and end-to-end encrypted.

memory

On-device AI inference

Gemma 4 runs on your phone via LiteRT-LM. Prompts and responses never touch a server you don't own.

save

Local-first storage

Entries live in an on-device SQLite database. Cloud sync is optional — and off by default.

AES-256-GCM backups

Backups to Google Drive or Dropbox are encrypted with a password only you know — before they leave your device.

Questions, answered

If you have one we haven't covered, open an issue on GitHub.

Is NoteItUP really free?
Yes — completely free, with no ads, no trackers, and no premium tier. The app is open source under the MIT license, so you can audit, fork, or self-build it any time.
Does my data ever leave my device?
Only if you explicitly turn on cloud backup. By default, every entry, image, and AI response stays on your phone. If you do enable Google Drive or Dropbox sync, backups are encrypted with AES-256-GCM using a password you choose — before they're uploaded.
Which platforms are supported?
Android is the primary platform and is live on the Play Store today. iOS and Desktop (macOS, Windows, Linux) builds exist in the codebase via Kotlin Multiplatform / Compose Multiplatform and will be published next.
How does the on-device AI actually work?
NoteItUP ships Google's Gemma 4 (2B parameters, instruction-tuned) and runs it locally using LiteRT-LM, Google's on-device inference engine. The model is downloaded once, then every "Improve clarity" or Brainstorm chat happens entirely offline.
Can I import from Day One or Joplin?
Yes. NoteItUP imports full Day One archives (with photos) and Joplin .jex exports. You can also restore from any previous NoteItUP backup. Exports go out as JSON, CSV, Markdown, or formatted PDF.
Where do I report bugs or request features?
On GitHub Issues. PRs welcome too.
