Dual-model AI · Live

The AI that sees
phishing coming.

Two independent BERT models cross-check every message, right from your Gmail inbox. When they agree you get a confident verdict. When they don't, you get an honest "verify manually".

Public demo running on two independent Hugging Face models. Free-tier models nap when idle, so the first scan can take a moment.

How it works

Two brains. One verdict.

Paste an email, or scan straight from Gmail. Zypher runs it through two independently trained models and only calls it safe when both agree.

01 / CAPTURE

Paste, or click "Scan with Zypher" in Gmail

The extension reads the message body for you, so there's no copy-pasting on Gmail.

02 / CROSS-CHECK

Two models, one verdict

An Enron-trained model and a Kaggle-trained model each score the text. Agreement is the bar for a confident answer.

03 / DECIDE

A clear, honest answer

Phishing, safe, or when the models disagree, an honest "uncertain, verify manually".

# example scan, via the API curl -X POST https://zypher-bakend.onrender.com/scan \ -H "Authorization: Bearer zyp_live_..." \ -d '{"content": "Your account will be suspended, click here..."}' → {"verdict": "phishing", "confidence": 0.94, "reason": "Both models agree — this is phishing."}
The models

MSc-grade AI, built from scratch.

Both models are fine-tuned BERT classifiers from the PhishGuard research project, trained on different corpora so they catch different things.

FAQ

Good questions.

Does Zypher store the emails I scan?

We log the verdict, confidence and a timestamp to track your usage. Scan content isn't stored or used to train models. See the terms and privacy policy for the full detail.

What happens when the models disagree?

You get an honest "uncertain, verify manually" instead of a guess. We'd rather say we don't know than be confidently wrong.

Do I need to install anything?

No. Paste text into the scanner above and it works. The Chrome extension adds a one-click scan button inside Gmail.

Can I cancel Pro?

Yes, any time. Email zaynasif59@gmail.com or use your account. Billing stops and your plan drops back to Free at the end of the period. Details are in the terms.

Accuracy note: Zypher AI scores about 99.5% on its test datasets, which means it will occasionally be wrong. Don't treat a "safe" result as your only reason to trust a link or a request for money. It's a second opinion, not a guarantee. Full detail in the terms & privacy notice.

Zypher AI grew out of my MSc research into AI phishing detection (PhishGuard). I built the models, the extension and the backend myself, and I read every message sent to the address below.
