ParallaxAI that researches with you, not for you.
It reads the page you're on, verifies claims against live sources, and surfaces what you'd miss.
What you'd see, in real time
Don't prompt
What it looks like, unprompted
You don't tell it what to check. It reads what you're reading, cross-references it against live sources in the background, and only interrupts when something doesn't hold up — a claim that contradicts its own source, a stat that's stale, a framing the data doesn't support. No prompt required, because the things worth catching are exactly the ones you wouldn't think to ask about.
It reads every tab you open.
Silently, in the background.

Parallax running live — it caught a 100-year date error on this page without being asked.
Unprompted
It reads what you read and checks it in the background. You never write a prompt.
Ranked by severity
It separates real errors from nitpicks, and tells you which is which.
Primary sources
Every flag links to the actual source, so you verify in one click.
ChatGPT tells you what it found. Parallax checks whether what you're reading is true.
