The AI that proves it — or refuses.

Cove is grounded, verified, low-hallucination intelligence. She cross-checks independent sources before she answers, shows her receipts, and is designed to cite, verify, or say when she does not know.

cove — live receipts
> Did George Washington have wooden teeth?
FALSE — famous myth. His dentures were ivory, human teeth, and brass — never wood. (mountvernon.org, si.edu, loc.gov)
[legend_check · refuted · 3 sources]
> Who was the first president? Who was his vice president?
1) George Washington. 2) John Adams. Cross-checked across 9 independent sources.
[crosschecked_fact · 9 sources · 0.92]
> Is human teleportation possible?
Researchers are exploring this — there is no verified method. The popular version comes from fiction (e.g., Star Trek).

Four honesty states

Every answer tells you how much to trust it.

Most AI sounds equally confident whether it's right or making things up. Cove labels what she knows — and what she doesn't.

VERIFIED

Cross-checked against independent sources, computed, or logically proven. Answered with receipts.

[crosschecked_fact · 9 sources · 0.92]
FRONTIER

Active research, no verified result yet. Cove says exactly that — instead of inventing one.

"There is no verified method."
LEGEND

Famous myths get flagged FALSE and corrected with sources — not repeated back to you.

Wooden teeth? Napoleon short? Flagged.
HONEST GAP

When she can't verify, she tells you. No padding, no bluffing, no confident nonsense.

"I can't verify that, so I won't guess."

How it works

Proves it, or refuses. In three moves.

Cove doesn't generate an answer and hope. Each question runs through a verification pipeline before a single word reaches you.

01 / DECOMPOSE

Split into checkable claims

Compound questions are broken into individual claims — each one small enough to actually verify.

"first president + his VP" → 2 claims
02 / VERIFY

Check each claim against reality

Facts are cross-checked across independent sources. Math is computed, not predicted. Logic is proven step by step.

9 independent sources agree → verified
03 / ANSWER WITH RECEIPTS

Or refuse, honestly

You get the answer plus how it was verified. If verification fails, you get an honest gap — never a confident guess.

Ask her something you think she'll get wrong.

That's the whole pitch. Cove verifies or refuses — and either way, you'll see the receipts.
