Three pillars

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.

In the wild

Real verdicts on real pages.

Tested live during build — these aren't mockups, they're actual results from real scam patterns.

BiniGuard popup showing Protected status with 0/0/0 threat counters

Popup — toolbar icon shows "Protected" status, today / month / total stats, and per-tab quick actions.

SpecSense yellow verdict on deceptive AI music upload using real artist names

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.

SpecSense red verdict on Amazon 6TB SSD for 8.83 euro fake capacity scam

Red "6TB SSD for €8,83" on Amazon — economically impossible for that capacity. Classic fake-capacity flash drive scam. Don't trust as-is.

How SpecSense judges AI music

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.

Privacy

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.

FAQ

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.
