NOTERA
Calm, Distraction-Free Notes & Tasks for Chrome & Windows
A workspace that remains beside your workflow rather than forcing a separate productivity environment. 100% private, local storage, 3 desktop workspace modes, selection bubble toolbar, dual Side Panel/HUD interface, and zero cloud lock-in.
Think Without Interruption
Traditional productivity suites force an unnatural rupture: to capture a thought, you leave your research tab, launch a heavy cloud app, wait for synchronization, and lose your cognitive train of thought. Notera inverts this paradigm.
Side Panel & Floating HUD
Work side-by-side with web documentation without switching tabs. Press Alt+H to summon an elegant floating, draggable quick-note overlay anywhere on screen, with a dense Folder Compact View across all surfaces.
Markdown & Task Alarms
Type markdown naturally. Checkbox syntax - [ ] dynamically extracts into interactive to-do lists preserving due dates, with customizable acoustic alarms and persistent toolbar alerts.
10 Curated Themes
Crafted for visual tranquility: Obsidian, Paper, Sepia, Nordic Frost, Forest, Midnight, Sage Garden, Alabaster Oat, Espresso Roast, and Twilight Slate with tailored WCAG contrast.
100% Local Storage
Zero external servers, zero telemetry scripts, zero accounts required. All notes stay strictly inside your browser with automated JSON backups to Downloads.
Experience Notera's Tactile Flow
Test Notera's core interface mechanics directly in this sandbox simulation. Switch themes, edit markdown, toggle interactive checklist items, or test web clipping.
Notera for Windows
Experience zero-latency calm computing directly on your desktop. Built with Tauri v2 and a Rust native backend, Notera v1.5.0 delivers 3 distinct workspace navigation modes (Default, Dynamic, and Elegant), floating selection bubble formatting, sub-15MB idle footprint, and global Always-on-Top shortcut pinning.
3 Desktop Workspace Modes
Switch instantly between Default (hierarchical sidebar), Dynamic (ultra-compact left rail & multi-note tab strip), and Elegant (recovering 42px canvas space with center focus branding).
Always-on-Top Floating Pin
Press Alt + P anywhere across Windows 10/11 to toggle persistent top-level pinning over IDEs, browsers, and terminals without stealing focus.
Sub-15MB & <2.5ms Speed
Engineered with Rust and Windows WebView2 runtime. Instantaneous cold boots under 120ms, zero-allocation stats traversal (<2.5ms), and FlashWindowEx taskbar alarms.

Engineered for Data Sovereignty
Notera operates with strict isolation from external services. No proprietary sync clouds, no analytics beacons, and no intermediary servers.
Web page DOM where research and reading occur. Notera captures highlighted text via Alt+N without altering host page styles.
Lightweight background controller handling keyboard shortcuts, context menus, Chrome alarms, and offscreen audio alert scheduling.
Persistent Chrome Side Panel, toolbar popup, draggable floating HUD (Alt+H), or dedicated Windows Desktop native window (Tauri v2) with multi-level folder hierarchy and Folder Compact View.
Data is committed directly to chrome.storage.local or local filesystem in desktop runtime. Automated cron exports generate timestamped JSON backups and direct .md import.
ZenDocumentEngine v1.5.0 (AST)
Custom ProseMirror-inspired AST block engine with floating text selection bubble, zero-allocation linear statistics traversal (<2.5ms), word-boundary undo/redo, 4-level nested lists, natural language task parsing (#list, @due, !priority), and SVG checkmark micro-interactions.
Floating HUD & Desktop Frame
Press Alt+H for browser HUD or run the native Tauri v2 desktop application with Alt+P Always-on-Top pin. Position anywhere across multi-monitor setups without interrupting active workflows.
Master Vault & Disk Snapshots
Zero-knowledge AES-256-GCM encryption at rest with PBKDF2 (100k rounds) key derivation, 20-character emergency recovery key, 3-tier task priorities with real-time overdue badges, and automated JSON/Markdown disk snapshots.

Your Thoughts Stay on Your Machine
Notera rejects the surveillance economy. We do not monetize your writing, train models on your notes, or require user registration.
No Analytics or Trackers
Notera bundles zero tracking scripts, zero Google Analytics, and zero third-party SDKs. You can verify this in Chrome's Developer Tools Network tab at any time.
No Login Gateways
No email required, no passwords to forget, and no identity profiles. Install from the Chrome Web Store or download the Windows app and begin writing immediately.
Works 100% Offline
Whether you are on an airplane, in a remote cabin, or experiencing internet outages, Notera performs identically. Your data lives strictly on your local disk.
