What it actually does.
1 · Phishing block
Hard-blocks known phishing URLs from aggregated public lists (PhishTank, OpenPhish, Phishing Army). 140K+ domains, refreshed daily. All checks happen locally — your URL list never leaves your machine.
2 · Heuristic warnings
Detects typo-squatting (gooogle.com), homoglyph attacks (Cyrillic-paypal via punycode), and risky TLDs. Soft-warn modal lets you continue at your own risk — no false-block paranoia.
3 · SpecSense (AI judgment)
Right-click a product on Bol/Amazon/AliExpress/eBay/Temu — or a YouTube video — and BiniGuard asks Gemini AI whether the listing is honest. Free Gemini key, your key, your call. Catches fake-SSDs, impersonator AI-music, counterfeit specs.
Real verdicts on real pages.
Tested live during build — these aren't mockups, they're actual results from real scam patterns.
Popup — toolbar icon shows "Protected" status, today / month / total stats, and per-tab quick actions.
Yellow "Adele & Gregory Isaacs" upload — AI is disclosed in the description, but the title still impersonates real artists. Channel "Zion Groove Station" doesn't own those names. Sus.
Red "6TB SSD for €8,83" on Amazon — economically impossible for that capacity. Classic fake-capacity flash drive scam. Don't trust as-is.
AI music is fine. Deceptive attribution is the scam.
BiniGuard doesn't flag AI. It flags dishonesty. The rules:
- Green "Inspired by [artist]" framing + AI disclosed → legit AI release.
- Yellow AI disclosed in description but title still presents real artists as performers → confusing, sus.
- Red Real artist names used as creator with zero disclosure anywhere → deceptive, classic scam upload.
Plus auto-trust for verified YouTube label/Topic channels — Twisted Records, Hospital Records, Ninja Tune, all - Topic auto-generated channels and ~80 known-legit labels. Right-click "Trust this channel" adds your own.

What BiniGuard never does.
- No tracking. Not us. Not anyone. No analytics, no telemetry, no fingerprinting.
- No data-selling. Nothing collected = nothing to sell.
- No ads. Anywhere. Ever.
- No account. No sign-in, no email collection.
- No SpecSense without your consent. Page content goes to Gemini only when you right-click and ask. Off by default.
- Your Gemini key stays local. We never see, store, or route it.

Common questions
- Is it really free?
- Yes. No paid tier, no premium upsell. BiniGuard is the funnel into the rest of Biniru's paid toolkit — those tools fund the free side. See the story →
- Why do I need my own Gemini key for SpecSense?
- Because we don't proxy your queries through our servers (privacy) and because we'd otherwise be giving you our compute budget for free. Free Gemini keys are 2 minutes to set up at aistudio.google.com — 1.500 requests/day per key, no credit card. Once Biniru runs its own local LLM ("Mind" tier on the funding ladder), the BYOK requirement goes away.
- Does it work on Chrome / Edge / Safari?
- Firefox + Chrome + Edge — yes, Manifest V3 cross-browser. Safari would need a separate Xcode build; not committed yet.
- What about mobile?
- Firefox for Android supports extensions and BiniGuard works there. Chrome Android doesn't allow extensions. iOS Safari is locked out by Apple.
- I got a red verdict on a legit channel. What now?
- Click "Trust this channel" in the verdict modal. The channel name gets added to your local whitelist — never flagged again, just for you. We also bundle ~80 known-legit label channels so you usually don't have to.
- Is the code open source?
- Yes. The whole codebase, including the 70+ unit tests we ran during build, is auditable. Permissions are minimal and justified.
