How can we help?

Click the 'Install on Chrome' button on any extension's page. You'll be directed to the Chrome Web Store where you can add it in one click. No account required.

No. All AlphaByteCore extensions are account-free. Your settings, data, and preferences are stored locally in your browser using Chrome's secure storage APIs.

Core features are always free. Some extensions offer optional premium features available via a one-time purchase. Extensions marked 'Free' in the store have no paid tier.

Chrome updates extensions automatically in the background. To force an immediate update, go to chrome://extensions, enable Developer Mode, and click 'Update'.

Right-click the extension's icon in Chrome's toolbar and select 'Remove from Chrome'. Or go to chrome://extensions, find the extension, and click 'Remove'. All local data is deleted on removal.

Not by default. You must manually enable each extension for Incognito mode in chrome://extensions → click the extension → toggle 'Allow in Incognito'. Note that data created in Incognito is not saved.

Email support@alphabytecore.com with the extension name, your Chrome version (chrome://settings/help), OS, and a description of what happened. Screenshots are very helpful. We aim to respond within 24 hours.

Send your feature request to support@alphabytecore.com with the subject 'Feature Request: [Extension Name]'. We read every message and consider all requests for the roadmap.

No. ZeroTrust uses a fully asynchronous scanning pipeline that runs off the main thread. Benchmark tests show less than 3ms average overhead per page load.

You'll see an overlay with the threat category, severity level, and details about what was found. You can dismiss and proceed, or block the page.

The community database syncs automatically every 6 hours. You can also trigger a manual refresh from the extension popup. Rules are applied instantly.

Yes. Right-click the ZeroTrust icon on any page and select 'Trust this domain' to permanently whitelist it. You can manage your whitelist in Settings.

No — it's complementary. ZeroTrust focuses specifically on browser-level threats: malicious scripts, phishing pages, and malicious redirects that traditional AV often misses.

Yes. ChromaStudio samples from the final rendered pixel output, so it works on video frames, WebGL canvases, and CSS-rendered gradients.

It uses your personal Anthropic API key to send a prompt to Claude. The key is stored in Chrome's secure local storage and is never sent to any AlphaByteCore server.

Unlimited. Color data is stored in Chrome's local storage with no cap. You can export and back up all palettes as a JSON file.

The eyedropper works on all standard web pages. Some browser-native UI elements (like dropdown menus) can't be sampled due to Chrome security restrictions.

We cannot recover your vault — there's no server, no key escrow, no reset mechanism. We strongly recommend writing your master password on paper and storing it securely offline.

Manual export/import is supported for device migration. Encrypted cross-device sync via your own storage (iCloud, Dropbox) is on the roadmap for v1.0.

Yes, but treat it as a secondary vault until v1.0. The core encryption is stable; some UI flows are still being refined. Always keep an export backup.

VaultGuard uses k-anonymity: your password is hashed, and only the first 5 characters of the hash are sent to the HIBP API. The full hash is never transmitted.

We're targeting Q3 2025 for the public beta. Sign up for early access at support@alphabytecore.com with the subject 'SentinelX Early Access'.

ZeroTrust uses a threat signature database — it's excellent for known threats. SentinelX uses behavioral AI to catch unknown, novel threats. Together they provide comprehensive coverage.

Basic behavioral analysis runs entirely on-device using a local ML model. The AI explanation feature optionally uses your Anthropic API key for richer analysis.

Yes. Enterprise features including custom rule distribution, team dashboards, and SIEM integration are planned. Contact us for early enterprise access.

NotePin uses a multi-signal anchor — element type, text content, structural position, and CSS selectors. If the element moves, NotePin follows it. If the element is removed, the note is flagged as 'orphaned' and kept for manual resolution.

Unlimited. Notes are stored in Chrome's IndexedDB which has no meaningful size limit for text data.

Yes. Many users use NotePin as a research annotation tool, then export as Markdown to import into Obsidian or Notion.

Not by default — you need to enable the extension for Incognito in Chrome's extension settings. Notes created in Incognito are not saved when the session ends.

NexusTab shells in under 100ms. Content loads asynchronously, so the tab never feels blocked. Average full load is 300-400ms on a normal connection.

Yes. The dashboard shell, your tasks, saved quick links, and last-fetched weather all load from cache when offline. Feed updates require a connection.

NexusTab fetches headlines from your configured sources and sends them to the Anthropic API (using your API key) to generate a natural-language summary.

Yes. Every widget can be individually toggled in Settings → Layout. You can run NexusTab as a minimal speed dial if you prefer.

It works on 99%+ of sites. Pages with complex CSS transforms (3D effects) may capture with slight rendering differences. Chrome's internal pages (chrome://) cannot be captured by design.

Up to 30,000px height. For pages taller than this, SnapFull auto-splits into multiple images named sequentially.

No. All screenshots are stored locally in your browser's extension storage. The shareable link feature uses a temporary local URL that expires when the tab is closed.

Yes. Screenshots in the Library can be reopened in the annotation editor at any time.

Yes. FocusGuard supports path-level rules. You can block reddit.com/* while allowing reddit.com/r/programming, for example.

Yes, but you need to enable the extension for Incognito mode in Chrome's extension settings.

Strict Mode locks the extension settings and blocklist behind a PIN. During active Strict Mode, the PIN is required to make any changes. It cannot be disabled once activated until the session ends.

Not yet. Cross-device sync via Chrome Sync API is planned for v2.2. Currently, you can export and import your blocklist as JSON.

Open-Meteo for the core forecast model (global, free, high-resolution). This is supplemented with government meteorological data where available for hyper-local accuracy.

Only for automatic detection. You can manually type any location without granting GPS access. Coordinates are used only locally and never transmitted to AlphaByteCore.

SkyCast sends the current forecast data to Claude via your personal Anthropic API key and asks for a practical, plain-English interpretation. The key is stored locally only.

Days 1–5 are highly reliable (>90% accuracy). Days 6–10 have increasing uncertainty — SkyCast shows confidence bands to make this clear.

Rarely. It uses a smart CDN allowlist to avoid blocking legitimate resources. Sites that do break can be whitelisted per-site or per-feature in one click.

uBlock Origin is excellent at ad/tracker blocking. PrivacyShield adds fingerprint spoofing, cookie intelligence, and a visual network graph — capabilities uBlock doesn't have. They complement each other.

For logged-in sessions, fingerprinting is less effective since the site knows who you are via your cookie. Fingerprint spoofing primarily protects cross-site tracking for non-logged-in browsing.

Yes. The blocklist syncs with the latest filter list versions automatically. You can also trigger a manual refresh from the extension popup.

Locally in Chrome's IndexedDB by default. Optional encrypted sync using your own cloud storage (AWS S3, Dropbox) is available in Settings → Sync.

ClipMind sends the article text to Claude via your personal Anthropic API key. The key is stored locally and never seen by AlphaByteCore.

Yes. Import from Pocket, Instapaper, Readwise, and standard HTML bookmark files.

You'll lose the local library unless you export it first. Always use File → Export Library before uninstalling.

Yes. Go to Settings → Feeds → Add Custom Feed. Any standard RSS 2.0 or Atom feed URL works. Add as many as you want.

DevFeed is specialized for developer content reading — it goes deep on feed management, GitHub integration, and reading experience. NexusTab is a broader productivity dashboard with weather, tasks, and a focus timer alongside a feed widget.

Absolutely not. Your preferences and reading history never leave your device. There's no account, no tracking, and no analytics whatsoever.

Yes. Click the pause icon in the top bar to stop feed refreshing. This also integrates with FocusGuard — when a Pomodoro session is active, feeds auto-pause.
