Kickstarter 2026  ·  Ask Every AI At Once

Don't ask
one AI.
Ask them all.

Ask once. Claude, Gemini and Grok answer — three independent opinions — and Google checks them against the live web. R4 gives you the call, shows you where they disagree, and flags what's likely out of date. Great on one phone. Better on two.

One opinion
One phone, one AI answer, no way to check it
The whole field
Two phones on the Rackit4 stand — R4's call on one screen, every AI's answer on the other

Rackit4 — R4's call on one screen, every AI's answer on the other
The Field
R4's call on one screen. Every AI's answer on the other.

The Problem

Every AI is confident. They can't all be right.

You already keep three of them open. You ask the same question twice because you don't trust the first answer, and you have no way to tell which one is out of date. Nobody is grading them. R4 does.

3
opinions
Claude, Gemini and Grok answer independently. Gemini runs ungrounded, so it isn't Google repackaged.
1
reality check
Google searches the live web — current facts, real sources, and the catch when a model is stale.
1
call
R4 reconciles them, names who to trust, and tells you when to doubt it.

Engineered For This

R4
Neutral By Design
No favourite model, nothing to sell you. When the AIs disagree, R4 shows the disagreement and says which voice to weight — the one thing a single AI structurally can't be.
R4
The Live-Web Catch
Models stop learning at a cutoff. Google doesn't. R4 fires a web check when the answer is time-sensitive and flags what the models got wrong.
R4
Great On One. Better On Two.
The full loop runs on a single phone. Add a second and the field gets its own screen — R4's call on one, every answer on the other.
Hardware
A Working Angle
Engineered for desk use. Both screens readable without lifting your head, and they hold where you set them.
Hardware
Folds Flat
Precision-formed stainless steel that folds flat. Desk-ready in seconds. Pocket-ready in one motion.
Hardware
Stainless Steel
Precision stainless steel hinges hold both phones exactly where you set them, and keep holding after thousands of open-and-close cycles. Built to outlast your phones.

Stop trusting
one answer.
