Show HN: Alethecs – fact-checks a claim and shows its own reasoning gaps

Alethecs, a new fact-checking tool showcased on Hacker News, investigates claims by breaking them down into sources, evidence, and contradictions, and actively attempts to disprove its own conclusions. The tool provides an evidence graph, a skeptic check, and receipts for each answer, aiming to offer transparent and honest verification.

How it works #

Method Alethecs breaks a claim down into its sources, its evidence, and its contradictions, so you can see how the answer was reached instead of just being told to trust it.

01

Investigate

Ingest a URL, document, message, or problem as an untrusted case.

02

Connect

Extract claims, map sources, and build an interactive evidence graph.

03

Challenge

A skeptic pass actively tries to disprove the current conclusion.

04

Explain

Every claim ships with receipts - the chain of evidence behind each answer.

05

Act

Draft a response, generate a report, or monitor the source for new evidence.
