## SETI Protect

Most browser security assumes the person who typed the password is still the person using the browser five minutes later. SETI Protect attacks that assumption. Built by Smart Eye Technology, Inc. and distributed through the Chrome Web Store, the extension uses continuous facial tracking to keep verifying your identity while you browse, rather than checking once at login and then trusting whatever happens next.

That continuous model is what lets it address session jacking, where an attacker inherits a browser that is already authenticated, and remote desktop intrusions, where someone else gains control of a machine that is already signed in. In both cases a single login check offers no protection, because the login already happened. SETI Protect instead treats identity as an ongoing state to be re-confirmed from the webcam feed.

It is part of a broader biometric authentication framework from the same vendor, which the company describes as combining facial recognition with fingerprint, handwriting and voice verification for multi-factor protection. The store listing is update-maintained — version 9.0.1 shipped in late August 2025 — and carries a 4.8 out of five rating from a small early user base. Because it processes personally identifiable biometric information, the developer publishes a privacy policy and declares that data is not sold to third parties or used outside core functionality; as with any biometric tool, teams in regulated environments should review that policy and any spoof-resistance research before relying on it as a sole authentication factor.

**Pricing & Plans:** The extension itself installs free from the Chrome Web Store. Commercial and enterprise licensing is handled through the vendor, Smart Eye Technology, Inc., so pricing is quoted on contact rather than published as fixed tiers.

- **Continuous facial recognition:** Instead of verifying you once at sign-in, SETI Protect keeps checking the face at the keyboard for the whole session.
- **Session jacking protection:** Because authentication continues after login, a passerby who takes over an unlocked, already-signed-in browser is detected rather than trusted.
- **Remote desktop hack defense:** The extension is positioned to stop remote desktop takeovers, a common route for attackers into an authenticated browser.
- **Multi-modal biometric framework:** Built by Smart Eye Technology, whose framework layers facial recognition with fingerprint, handwriting and voice verification as biometric MFA/2FA.
- **Privacy disclosures:** The developer declares data is not sold to third parties and not repurposed outside the extension's core function, with a linked privacy policy.

**Strengths:** Continuous verification closes the gap left by one-time login checks; Directly targets session jacking and remote desktop takeover; Part of a wider biometric MFA framework covering several verification signals; Maintained listing with recent updates and a high user rating

**Limitations:** Uses a webcam for continuous facial tracking, which some users find intrusive in shared or public spaces; Third-party research on spoof resistance of facial MFA varies, so it should complement rather than replace strong passwords; Privacy-sensitive by nature: it processes personally identifiable biometric information; Small install base relative to mainstream security extensions

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
