Tests for factual traps and potential hallucinations
False-premise traps, source grounding, prompt-injection resistance and adversarial pressure to guess — each run through the configured chain and scored by deterministic checks.
Check the facts. Challenge the reasoning. Review the sources. As a legal adviser, lawyer, board member, doctor, healthcare professional, estate agent or notary, you need more than a convincing answer. IamVERA brings different AI models together to review an answer and makes their checks visible. For document tasks, the Semantic Privacy Shield replaces detected sensitive details before approved context reaches external AI providers.
*Your professional judgement remains central.*
Built in the EU · Designed for professional workflows
An answer can sound convincing while containing an unsupported claim, a missing qualification or a reference that does not support its conclusion.
"Do not judge an answer only by how confidently it is written. Examine how it was checked."
Vera helps you examine AI-generated answers before you use them in your work. Its verification process checks the content; its Privacy Shield controls the release of transformed document context. Neither guarantees that every error or identifying detail will be detected.
An AI answer verification layer for professional work. Vera cross-checks one answer through independent models that audit facts, challenge reasoning and verify live sources, then shows every correction, disagreement and source behind the final answer.
Not a single language model. Not a guarantee of truth. Not a replacement for professional judgement. Final responsibility for acting on an answer stays with you.
Choose the checks that suit your task. With the full verification chain selected, each model has a distinct role.
Claude drafts the initial response
GPT reviews factual claims for errors
Grok challenges the reasoning and assumptions
Perplexity checks relevant public sources
Claude drafts an answer using your question and the context available for the task. This becomes the baseline that every subsequent model evaluates — not a final answer, but a starting point for structured verification.
GPT (OpenAI) receives Claude's answer and reviews each factual claim for possible errors, inconsistencies and missing support. Corrections, confirmations and confidence levels are returned — not as a replacement answer, but as a structured review of the first response.
Grok (xAI) examines assumptions, challenges the reasoning and raises alternative interpretations. It looks for missing context, ambiguous framing, and important distinctions that the first two models may have glossed over. Disagreement is a feature, not a bug.
Perplexity checks relevant claims against available current public sources. Claude then incorporates the review findings into the final answer — with every correction and source visible.
Vera records the selected model steps, review findings, corrections and sources. You can examine what was questioned, what changed and where assessments differed — rather than relying on the final text alone.
We publish tests of our verification chain, including unsuccessful checks and the underlying run data.
These are tests of our own system, with small samples and results that can vary between runs and model versions. They show observed behaviour, not a guarantee that your next answer will be correct.
False-premise traps, source grounding, prompt-injection resistance and adversarial pressure to guess — each run through the configured chain and scored by deterministic checks.
Where a check fails or the models disagree, we show it. A benchmark that only ever passes proves little; the disagreements are where the chain earns its keep.
Every result links to the underlying JSON: model calls, corrections, costs and judge output. Nothing summarised away.

View plans and prices →The Privacy Shield is a separate utility inside Vera. Before document context reaches an external model, it replaces detected sensitive values with synthetic placeholders. The AI chain receives the transformed context; the original values are restored locally. It is a privacy-control workflow, not an end-to-end guarantee against leakage.
Names, dates, references to minors, diagnoses, criminal-law context, case numbers — replaced locally with realistic synthetic values. Roles and relationships stay intact, so the AI still understands the file.
A local check confirms no detected real values remain in the prepared text. If it is not clean, nothing is sent. Fail closed — no exceptions.
The verified answer is restored locally with the original values. You get a normal, usable answer — the public AI never saw the real data.
// Sent to the AI chain — fictional example
Mrs Dylan Knoers [[DOC001_ADULT_PERSON_001]] states that her ex-partner Mr Tobias Evers [[DOC001_ADULT_PERSON_002]] became aggressive on 06-01-2026 [[DOC001_DATE_001]] during the handover of her minor daughter [[DOC001_MINOR_CHILD_001]].
Built for professionals bound by confidentiality — lawyers, notaries, judges, physicians, occupational health physicians, psychiatrists, investigative journalists.
The Privacy Shield protects documents inside Vera. Vera X-Ray starts one step earlier: on your own device. It detects sensitive values in a document, lets you review what will be shared, and sends Vera only the context you approved.

Your Vera environment and document-protection processing are hosted in the EU. Your instructions and approved, transformed context can reach selected external AI providers through OpenRouter. Those providers may process information outside the EU. "Local" therefore means within your protected Vera environment, not necessarily on your own device.
Vera Office combines privacy-preserving AI document analysis, multi-model verification and controlled AI document editing inside a browser-based DOCX workspace. Open a document and ask, for example:
"Summarise this document."
"Rewrite this paragraph more formally."
"Replace this phrasing throughout the document."
Vera processes the document content through the Semantic Privacy Shield. Sensitive values are replaced locally before the selected AI models analyse the document. Afterwards, the original values are restored locally.
For edits, Vera first builds a controlled action plan. Only validated changes are executed and saved — a model never gets unrestricted access to your file.
Document analysis, multi-model verification and controlled document editing in one secure working environment.
A verification tool that obscures its own data handling would undermine the very thing it promises. So we don't.
Chat-uploaded PDFs are processed temporarily in memory for the active run; metadata may be retained for session history.
Vera Office documents remain in the customer-isolated environment until an authorised user deletes them.
Model calls — including document content in the context — are sent to the configured AI providers via OpenRouter. This is stated clearly, not buried in a privacy policy.
Vera is built and operated within the EU. We are working towards full GDPR processor documentation. We will only claim compliance when the documentation is complete.
Vera is designed for work where AI output is acted upon — not just read.
Have a draft analysis reviewed for unsupported claims, unclear wording and missing qualifications before you incorporate it into advice or an internal document.
Challenge the reasoning in a draft argument, examine cited public sources and identify questions that require further legal research before you use the result.
Review a report or proposal for assumptions, missing information and unsupported conclusions before it becomes part of your decision-making.
Structure a report or make an existing explanation easier to understand. Keep the task focused on documentation, with clinical judgement remaining yours.
Turn supplied notes into a clearer draft summary or handover. Review whether observations, interpretations, agreements and outstanding questions have been kept distinct.
Review property descriptions, correspondence and agreement summaries for inconsistencies or unsupported statements before sharing them with your client.
Give a draft deed or explanatory note an additional review for inconsistent wording, unclear references and missing information before completing your own professional checks.
These are suggested applications, not guarantees of specialist accuracy. The medical and care examples concern text support and documentation, not diagnosis or treatment decisions. Vera does not replace professional research, formal checks or your own judgement.

Direct answers about multi-model AI verification, potential hallucinations, source checking and confidential documents.
Use independent checks for factual claims, reasoning and sources rather than relying on the original model alone. Vera automates this by routing the answer through a configurable multi-model AI verification chain and exposing each correction, disagreement and source. The result remains subject to professional judgement.
Vera does not claim to identify every hallucination. It reduces the risk of undetected errors by having independent models audit factual claims, challenge assumptions and verify live sources. Conflicts are surfaced rather than hidden, so unsupported claims and missing evidence are easier to inspect.
A single model produces and judges its own answer. Vera separates roles across independent models: one formulates, another audits facts, another challenges the reasoning and another verifies sources. No single model has the final word without review.
Yes. Vera runs every model selected for the session in its configured role and records the resulting findings, corrections, sources, token usage and cost. The exact models can be configured per session.
When source verification is selected, Perplexity checks current public sources and returns references for the claims under review. Claude then incorporates justified findings into the final answer. The sources and model steps remain visible for inspection.
No. It means the answer passed through independent factual audit, adversarial challenge and live source verification, with corrections, disagreements and sources shown. Vera does not guarantee truth; it makes the verification behind each answer inspectable.
Vera's Semantic Privacy Shield transforms detected sensitive values inside the customer-isolated Vera environment before approved context is released to external models. A local privacy gate checks the outbound text and blocks transmission if verification fails. This reduces exposure but does not guarantee that every indirect identifier can be detected.
Vera surfaces disagreement rather than collapsing it into a false consensus. The final synthesis can incorporate justified corrections, preserve unresolved uncertainty and show which model raised each issue. You can inspect the evidence and remain responsible for the decision.
Chat-uploaded PDFs are processed temporarily for the active run and are not retained as reusable source files; file metadata and the relationship to the run may remain in session history. Vera Office documents do remain in the customer-isolated tenant environment, because opening, editing, saving, versioning and authorised collaboration require persistent document storage. Model calls, including document content in the context, are sent to the configured AI providers via OpenRouter.
Yes. You configure the verification chain per session. You can choose which models participate, see the tokens and cost per model call, and decide how much verification depth each question deserves.
You pay per verified question, not per token. One question through the chain is one run, whether it takes four model calls or seven. Starter is free for the first month and includes 10 runs in total. Paid plans start at € 79.00 per month excluding VAT. Run out before the month is over and you can buy extra runs or move up a plan. Full pricing.
Verification stops, with a clear message on screen. Nothing is charged silently and there is no unexpected invoice afterwards. You choose how to continue: wait for the new month, buy a run bundle, or move to a larger plan. Plans are priced on average usage within your profession, so light use balances out heavy use.
Vera replaces blind trust with structured verification. Every step visible. Every source traceable.
