SECURITY

Private by design.

No cloud. No telemetry. No backdoor. Everything lives in a single local database — encrypted with AES-256-GCM authenticated encryption the moment you set a password.

  • AES-256-GCM authenticated encryption — tamper-proof
  • 6–64 character password, never stored in plaintext
  • 5 failed tries → 30-minute lockout, persists across restarts
  • 2.0 databases migrate seamlessly on first unlock
  • Recycle bin — deleted cards recoverable for 7 days
  • XSS-safe diary with double HTML sanitization

Everything you need to remember

From quick notes to a whole knowledge base — scroll through the highlights.

MEMO MANAGER

Memos, beautifully organized.

The central hub of Novara. Organize entries into custom groups, star and pin what matters, and move items between groups. Five entry types — Email, Account, API Key, Website and Custom — cover almost everything you need to remember.

  • 5 entry types
  • Groups & search
  • Star & pin

API KEY MANAGEMENT

Every key, verified in one click.

Store API keys in an encrypted database — safe from plaintext leaks. Right-click any key and Novara probes its endpoint with a GET /v1/models request (idempotent, no cost). It tries Bearer first, retries without it on 401/403, and works with both OpenAI-standard and domestic providers.

  • GET /v1/models probe
  • Bearer auto-switch
  • Save on success only

FILE PATH BACKUP

Your paths, always valid.

Save folders and files you use often — type them or pick with the built-in file/folder pickers. Novara continuously validates paths: green means alive, red means gone. One click copies, another opens it in Explorer.

  • Built-in pickers
  • Real-time validity
  • One-click copy & open

TASK DASHBOARD

Todos that think ahead.

Main tasks with subtasks — check them all and the card completes itself. Sticky notes expand when content grows. Right-click the empty area to add desktop countdown reminders that ring even when Novara is closed.

  • Smart subtask linkage
  • Sticky notes
  • Desktop reminders

DESKTOP STICKY NOTES

Your notes, right on the desktop.

Send any note card to your desktop with one click. A lightweight host process keeps them visible even when Novara is closed — drag, resize, lock in place, edit from the desktop, and everything stays in sync. Countdown reminders ring three times and pulse red when time's up.

  • Works without Novara
  • Drag & resize
  • Desktop reminders

DIARY

Your story, day by day.

A clean list of all your entries, with starred and pinned items lifted to the top and everything sorted by recency. Tap in and out of the editor seamlessly — your writing is always saved.

  • Star & pin
  • Auto-save
  • Recency sorted

RICH TEXT EDITOR

Write like you mean it.

A WebView2-powered editor with bold, italic, underline, colors and images. The floating capsule toolbar stays accessible, blank overwrites are blocked, and every HTML import is double-sanitized against XSS.

  • Floating toolbar
  • Image insertion
  • XSS-safe HTML
