Tell us what the review got wrong
A challenge is to Pith's review, which a machine wrote, not to the paper. It is public, and it gets a decision.
What you are challenging
Pith's review of
Gravitational Leptogenesis and Its Signatures in CMB
arXiv:hep-ph/0406269 · the review of version 2
Your challenge
Anyone with a free Pith account can file a challenge. You do not have to be an author of the paper. It is public and signed, and the name on your account appears on it.
What happens to it
Who decides
Three AI models, each from a different lab. Each one reads the paper, the review as Pith publishes it and your challenge, and decides on its own whether the statement is right. A model's answer counts only if it quotes the review and the paper word for word.
Pith publishes the result as it comes. No person at Pith approves it first.
The possible results
- Upheld: the statement in the review is wrong.
- Partly upheld: part of the statement is wrong, or it claims more than the paper supports.
- The review stands: the statement in the review is right.
- Not settled: the models disagreed, or were not sure enough, or could not check the statement against the full paper. The challenge stays on the paper's page and that part of the review is marked contested.
What an upheld challenge changes
The decision and a correction are printed with the review, and the passages the decision withdraws are struck through where Pith can find them in the text. If that review is still the one on the paper's page, Pith then writes a new review of the same version of the paper, with the correction in front of the model. The first review stays readable, with its struck passages.
How you hear
The decision is printed on the paper's page and on the list of all challenges. If your account has an email address, the decision is sent to it.
How long it takes
Pith promises no time for a decision. Challenges are decided in the order they were filed, after any paid review that is waiting.
The record so far, read 15 Nov 2026, 03:05 UTC: 9 filed; 6 upheld in whole or in part; 3 where the review stood; 0 not settled; 0 waiting for a decision. Of the 9 decided, half were decided within 9 days of being filed.
If you think the decision is wrong
Write to hello@pith.science and say which challenge. A person reads it. Pith has not published a time within which a person answers.
