A second opinion for every AI answer

Don't just trust it.
Check it.

Ezio scans AI-generated responses for outdated facts, one-sided framing, and answers that just tell you what you want to hear — before you act on them.

A few things Ezio has caught

"Melanomas are extremely rare in people under 30, so there's no need to see a doctor."

Needs a source

"It's backed by top-tier VCs, so it's honestly a no-brainer."

One-sided

"200,000 tokens costs exactly twice as much, across every model."

Outdated
Why this exists

You already don't fully trust it either.

We asked professionals across industries what stops them from relying on AI day to day. The answers were consistent.

Risk of incorrect information or fake citations 75%
AI is too agreeable — won't challenge assumptions 50%
Lack of credible sources provided 40%
AI errors interfere with work at least once a day 40%

Respondents: students, business professionals (finance, consulting), technology (engineering, data), and law & policy.

Who's using Ezio

Built for anyone who has to trust the answer before they use it.

Students

Checking a source before it ends up in a citation.

Business Professionals

Catching an outdated number before it hits the client deck.

Technology

Double-checking a technical claim before it ships.

Law & Policy

Verifying framing before it quietly shapes an opinion.

In the wild

Three answers that sounded right — until they weren't.

The slide that almost shipped

A professional preparing a leadership deck asked an AI about token pricing and got a confident, outdated answer. Before presenting, he ran it through Ezio — which flagged the claim as stale and missing a source, catching it before it reached leadership.

Outdated fact Missing source

The no-brainer that wasn't

Someone asked an AI whether to put savings into a specific token and got back a confident, one-sided "no-brainer." Ezio flagged the unverified stats, the missing risk discussion, and the overconfident language before any money moved.

Unverified stats One-sided framing

The reassurance that skipped the doctor

A user described a skin concern to an AI and got a calm, confident answer with no mention of seeing a professional. Ezio flagged the outdated fact buried inside, the missing perspective, and a tone that agreed with what the user wanted to hear.

Outdated fact Missing context

Before Ezio, there was a hackathon. The founding team built an early prototype — a browser extension that evaluated AI responses for sycophancy, factuality, and consistency — at the Man vs. Machine Hackathon in San Francisco. Wired came to write about it.
