✂️ Eliminate the Impossible
🕵️ A Sherlock Holmes tool — The consulting detective himself
His most famous maxim, turned into an engine. Describe a stubborn problem — a bug that makes no sense, a machine that won't start, a decision that won't resolve — plus any explanations you suspect. The engine extracts the hard constraints, tests every hypothesis honestly, strikes out what contradicts the facts, and names the single test that settles the survivors.
✅ Free to use — no account, nothing to configure.
What it does
Facts first
The hard constraints are extracted before any explanation is entertained.
Honest verdicts
Impossible, improbable, or possible — with the reasoning and the fact each dead hypothesis violates.
The deciding test
One concrete experiment or question that separates whatever remains.
How to use it
-
1
State the problem with every fact you know.
-
2
Add your suspected explanations, or let the engine supply candidates.
-
3
Read the elimination, run the deciding test, export the report.
For anything medical, legal, or financial, treat the output as reasoning practice and consult a professional.
