→Public epistemic assessment · Professional decision assurance
Know what the evidence justifies.
Keep every judgement visible.
Elethya determines what the available evidence justifies concluding while preserving the distinction between fact, testimony, interpretation, inference, prediction and judgement. Public questions build shared knowledge. Private professional assessments apply the same governed method to consequential decisions.
Evidence provenance, epistemic classification and governed reasoning — with the reasoning trail preserved.
⌁
ClassifyPreserve what kind of claim it is.
Fact, testimony, inference, prediction and judgement are not silently flattened into one category.

ConcludeSay only what the evidence justifies.
Including when the answer remains unresolved.
→How it works · The Aletheia method
From question to governed conclusion.
Elethya is the interface; Aletheia is the governed evidence and reasoning engine beneath it. The process preserves enough structure to reconstruct why a conclusion was reached instead of hiding the basis behind fluent prose.
Elethya determines what the available evidence justifies concluding. It preserves the distinction between fact, testimony, interpretation, inference, prediction and judgement. Subjective does not mean false; objective does not mean proven.
Public Elethya™ · Free
Questions worth investigating belong in public.
Anyone can submit a public question during the beta. Elethya selects suitable questions for evidence-based investigation and may publish the resulting assessment for everyone to inspect and share. Submission is free; selection is limited by evidence availability, public value and capacity.
Ask Elethya.
Submit an evidence-resolvable question without personal, confidential or commercially sensitive material. If selected, the question becomes part of Elethya's public investigation queue.
Public means public. A selected question and its assessment may be published. Do not submit private evidence through this path.
Submit public questionTechnology and productsWould a claimed product advantage survive inspection of the underlying evidence?
Science and public claimsWhat does the available evidence actually establish about a disputed claim?
AI and digital systemsDo reported performance gains survive inspection of the underlying evidence?
Economics, policy and everyday decisionsWherever a better evidence record can materially improve the answer.
Elethya follows questions, not sectors. Professional and corporate decisions are an important paid application of the system, not the boundary of what Aletheia is intended to understand.

Private decision assurance when the question cannot be public.
For consequential, confidential or organisation-specific decisions, Elethya offers governed private assessments. The initial enquiry is deliberately bounded: define the question and scope first; substantive evidence is handled only after appropriate arrangements are agreed.
Focused evidence question.
A bounded assessment of whether the supplied evidence supports a specific proposed commitment or conclusion.

Published library
Assessments should demonstrate the method, not merely advertise it.
The public library will grow through selected epistemic questions and governed assessments. Existing assessments remain available while the public-beta corpus develops.

Ask publicly. Decide privately.
If the question can be investigated openly, submit it to Public Elethya for possible free investigation. If the question involves private evidence, commercial sensitivity or a consequential organisational decision, start a Professional Elethya enquiry.
