## ⚡ The Problem with Microsoft Recall

| Feature | Microsoft Windows Recall | **NanoRecall (This Project)** |
| :--- | :---: | :---: |
| **Privacy & Cloud** | Unencrypted storage, telemetry risks | **100% Local & Encrypted** (Zero bytes leave your PC) |
| **Hardware Lock-in** | Requires expensive **Copilot+ PC ($1500+)** with 40+ TOPS NPU | **Runs on any standard Intel / AMD / ARM CPU** |
| **Vector Engine** | Heavy proprietary runtime | **[NanoVector](https://github.com/eminsk/nanovector)** (Pure C99 + AVX2, <120KB footprint) |
| **Search Latency** | Variable (Cloud / NPU overhead) | **0.28 ms** (Sub-millisecond exact semantic search) |
| **Password Protection** | Records sensitive credentials and cards | **Privacy Shield**: Auto-ignores 1Password, Bitwarden, KeePass, Incognito |
| **Storage Footprint** | Tens of gigabytes of raw frames | **Smart Frame Differencing**: Suppresses static frames (30–60 KB/frame) |
| **Code Footprint** | Gigabytes of OS bloatware | **<200 KB pure codebase**, <25MB RAM idle, 0.1% CPU |

## 🌟 Key Highlights

* **100% Private & Offline:** All frame embeddings and OCR snippets are stored in a single, local `.nvec` binary file. No accounts, no API keys, no internet required.
* **Powered by NanoVector:** Directly uses [NanoVector](https://github.com/eminsk/nanovector)'s C99 AVX2/NEON vector search engine for instant 90-microsecond semantic retrieval.
* **Intelligent Perceptual Frame Differencing:** Continuously monitors your display; if the screen hasn't changed by >1.5% (reading, idle, away from desk), capture is skipped to conserve disk space and battery.
* **Built-in Privacy Shield:** Automatically detects active foreground windows and terminates recording whenever password managers (`1Password`, `Bitwarden`, `KeePass`), private browsing windows (`Incognito`, `InPrivate`), or crypto wallets are active.
* **Dual Interface:** Instant lightning-fast terminal CLI (`nanorecall search ...`) and a sleek dark-mode local web dashboard (`nanorecall ui`).

## 🚀 Interactive Google Colab Demo
 
Test NanoRecall interactively in your browser with zero local installation:
 
[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/eminsk/nanorecall/blob/main/notebooks/nanorecall_quickstart.ipynb)
 
The [Interactive Colab Notebook](https://colab.research.google.com/github/eminsk/nanorecall/blob/main/notebooks/nanorecall_quickstart.ipynb) demonstrates:

- **Privacy Shield:** Live simulation blocking 1Password/Incognito windows and redacting API keys.
- **Desktop Memory & Search:** Ingesting sample desktop screens and querying via natural language in <0.3 ms.
- **Single-File `.nvec` Persistence:** Saving and restoring the entire screen memory index.
- **Colab CPU Benchmark:** Benchmarking search latency (15–300 µs) and QPS over 10,000 frames.

*(Requires Python 3.9+ on Windows, Linux, or macOS)*

### 2. Capture Your Screen

Capture and index your current desktop state:

```bash
nanorecall capture
```

Output:
```text
📸 Capturing desktop screen...
🔍 Extracting offline OCR text...
🧠 Indexing into NanoVector (Window: Active Window)...
✅ Indexed frame 2026-09-11_142315 (342 words, 98.4% change)
```

### 3. Natural Language Search (CLI)

Search for anything you saw hours, days, or weeks ago:

```bash
nanorecall search "github pull request sqlfluff"
```

Output:
```text
🔍 Search Query: 'github pull request sqlfluff' (1 results found in 0.28 ms)

#1 [98% Match] Google Chrome — sqlfluff pull request 8449 github
   🕒 Captured: 2026-09-11_142315
   📝 Text:     merged upstream/main to pull in CI fix and added StarRocks test cases...
   🖼️  File:     C:\Users\M_N_N\.nanorecall\frames\2026-09-11_142315.webp
```

### 4. Interactive Web Dashboard

Launch the local dark-mode dashboard with visual timeline scrubber:

```bash
nanorecall ui
```

Then open `http://127.0.0.1:8765` in your browser.

* Interactive daily timeline scrubber (scrub your day hour-by-hour).
* Instant search bar with live autocomplete and semantic similarity badges.
* Click any memory card to inspect the full-resolution screenshot with OCR highlights.

### 5. Background Daemon

Run NanoRecall silently in the background:

```bash
nanorecall daemon --interval 3.0
```

## 🛡️ Privacy Shield Rules

NanoRecall includes out-of-the-box protection rules. The following windows and sensitive tokens are automatically shielded from being recorded:

* **Password Managers:** 1Password, Bitwarden, KeePass, KeePassXC, LastPass, Dashlane, NordPass, Enpass.
* **Private Browsing:** Chrome Incognito, Edge InPrivate, Firefox Private Browsing, Tor Browser.
* **Crypto Wallets:** MetaMask, Phantom, Ledger Live, Trezor Suite, Exodus, Rabby.
* **Credentials & Tokens:** Credit card numbers, OpenAI API keys (`sk-...`), GitHub personal access tokens (`ghp_...`), and SSH/RSA private keys are automatically redacted.
