DeciderA second opinion, wherever you are on the web.
You already know the questions. Is this link safe? Is this email really from them? What am I agreeing to? Decider answers them in the page you are already looking at — in a sentence, not an essay.
What it does
Before you click
Right-click any link and ask. Decider reads where it really goes, what the page around it claims, and whether the two agree — the mismatch most phishing depends on.
“Do not open this link.”
In your inbox
Open a message in Gmail and a spam or phishing read happens on its own. Ordinary mail stays silent — no badge, no banner, nothing to dismiss.
“Do not trust this email.”
On the page you are on
Click the toolbar button and Decider suggests what is actually worth deciding here — about this product, this posting, this policy. Click a question and it answers that one.
“Should I buy this now, or wait?”
In the fine print
Land on terms or a privacy policy and Decider offers to read it for you. A side panel says what you would be agreeing to and what to be aware of before you do.
“Auto-renews yearly · Arbitration required”
How it works
You ask
Right-click a link, open a message, or click the toolbar button. No setup, no account, no configuration to get wrong.
It reads
Only what the question needs: the page you are on, the link you asked about, the message you opened. Nothing in the background.
It answers
One line where you are already looking. A number when the number matters. Nothing to read around.
Honest when it isn't sure
Most tools sound equally confident whether they know or not. Decider doesn't.
- It shows its confidence. Every answer carries how sure it is. When that number is low, Decider says so plainly instead of dressing up a guess as a verdict.
- “It depends” is an allowed answer. When a page genuinely doesn't settle your question, that is what you get — not an invented yes.
- It gets quieter, not louder. Ordinary mail and ordinary links produce nothing at all. The alert means something because it is rare.
- You can tell it when it's wrong. Every verdict has a Yes / No. Say no and the next call about that sender starts from your correction.
What leaves your browser
- Only when you ask, or when you open a message. Decider never reads pages in the background and never follows you between tabs.
- Only what the question needs. The page text, the link, or the message you opened — subject, sender, an excerpt, and the links inside it. Attachments are never read.
- No account, ever. There is nothing to sign into, so there is no profile of you to build. Verdicts are stored in your browser, not in an account.
- Gmail checking has an off switch. One toggle in the popup, and Decider stops looking at mail entirely.
Stop squinting at links.
Decider is free, and it is quiet until it has something worth saying.
