Agnosphere Fact Checker · Munich
The most dangerous error is the convincing one.
Convincing proves nothing. So the Agnosphere Fact Checker checks every claim against the sources the report cites, and when a source doesn’t hold, it keeps digging on its own until the claim stands or falls.
For sector analyses, consulting reports, strategy papers, IC memos and every document that needs to convince.
No obligation · no preparation needed

Agnosphere Fact Checker
One sentence, three claims,
one convincing error.
The Fact Checker splits every sentence into its individual claims and checks each one against the source the report cites and against the open web. Below is the result for one sentence from the sample report. The margin notes show which claim is the hallucination and what the sentence should have said.
Sample report · Page 3
“AI-server power density increased elevenfold between 2020 and 20251 and is projected to rise another fourfold by 20272; one advanced rack could then consume as much electricity over a year as 65 households3.[6]”
Verified
The cited IEA source and web search agree.
Verified
Matches the projection in the same source.
Wrong
The source says peak power, not electricity used over a year.
Suggested wording“one advanced rack could then have peak power demand equivalent to that of 65 households.”
That was one sentence. The full review covers all 77 claims in the report.

What happens to your report.
How we handle confidential reports, from the first request to the returned document.
The four rules
No document moves automatically.
Nothing is checked or shared until we have agreed the scope together. Uploads happen over a secured route, never through the public site.
Make data use explicit.
For each use case, we agree on access rules, data flows, retention, and model providers.
Keep evidence and open questions visible.
When decisions depend on sources, users can inspect the evidence and see what remains unresolved.
Keep responsibility with people.
Your team decides what can be automated, what must be reviewed, and who signs off.

Beyond the Fact Checker
Custom systems, built by the team behind the Fact Checker.
Research pipelines that check their own sources. Document workflows that keep the evidence chain visible. Review steps fitted to one team’s rules. Each of these systems is built for a single team, by the two founders on this page, under the same rule: tested on real cases before anything goes live.
Let’s talk about one concrete task
