A writing tool that audits footnotes

A footnote is an IOU.

It sits small beneath the text and promises: the source stands behind the sentence. An AI assistant that comes up empty signs it with a reference that does not exist. NotaVera collects on the promise: the real passage beside your sentence, judged blind, no author, no title, no year. The literature cites on credit.

How it works

From sentence to footnote. While others are still searching.

01

Write or paste

One paragraph. NotaVera immediately sees what most authors miss.

02

Every sentence shows its credentials

Supported, contested, boundary case, or open. Most authors learn the difference from the review report. You know it beforehand.

03

Only what holds becomes a footnote

The source must carry the sentence. Existing is not enough. No match means: you know it now, your examiner finds out later.

04

The margin pushes back

Counter-evidence stands beside the sentence. You can work with it or ignore it. The reviewer finds it either way. The question is who had it first.

NotaVera Text-Reuse Review

Half forgotten, now in your draft.

NotaVera finds the source. Turnitin finds you.

Read months ago, half forgotten, now in the text. Plagiarism software judges after submission. By then it's too late. NotaVera shows the passage as you write. Everyone else submits and prays.

A finding, not a flag.

A percentage is a suspicion. A passage is a work order: source, excerpt, revision.

A citation, not a case.

Citation markers, work identity, page context, and source quality are assessed together. Clean citation needs no defence.

An edge, not a coincidence.

NotaVera shows every finding to you first, in private, with no verdict attached. Nothing is rewritten without you.

Proof bench

See a check before you have an account.

Two real claims, two real sources, both open to inspection. No sample text, no invented DOI. What NotaVera shows here is the finding the editor produces.

The claim

A statistically significant result is necessarily scientifically important.

The source

The ASA Statement on p-Values: Context, Process, and PurposeAmerican Statistical Association · 2016 · Principle 5 · DOI 10.1080/00031305.2016.1154108

The finding

contestedThe source does not carry the word “necessarily”. A significant result may still be trivial, biased, or substantively unimportant.

What this does not prove: This static demonstration shows one bounded source–claim comparison. It is not a review of a manuscript and does not guarantee truth, originality, or publication readiness.

Your assistant flatters you

The most dangerous hallucination is agreement.

Nonsense used to at least sound like nonsense. Now it reads like peer review. A generative model is trained to agree with you; the expert on the other side is trained to refute you. NotaVera plays the second role while you can still change something.

Who NotaVera believes

Your client reads with goodwill, your team reads along. The other side is searching, and it is paid to.

NotaVera does not believe you either. But NotaVera works for you.

What you stop doing

Focus on the finding. Not the formatting.

Hunting for the passage that carries the sentence

You write the sentence; NotaVera looks for the source that actually supports it. No keyword search, no scrolling through results that turn out to be about something else.

Checking by hand whether a reference is real

Every DOI is resolved against Crossref before it is called verified. What cannot be resolved stays marked as a candidate instead of quietly passing as evidence.

Reformatting footnotes when the style changes

Citation style is a setting, not a rewrite. The same manuscript exports to Markdown, DOCX and PDF with the footnotes already in shape.

The result you can hand over

A finding someone else can check.

After a check, NotaVera can turn the finding into an Evidence Receipt: one page carrying the sentence that was checked, the sources separated by role, and a signature. You decide whether it becomes public, and you can revoke the link at any time.

A supervisor can verify it

The page names the checked sentence, every source with its DOI, and whether that source supports, contradicts or merely borders the claim. Nothing has to be taken on trust.

It stays yours to withdraw

Publication is a separate, explicit step, an expiry date is optional, and one click revokes the link. Nothing is published by writing.

It is bound to what was checked

The visible excerpt must occur in the sentence that was actually examined, and that binding is part of what the signature protects.

It records evidence fit for a scoped claim. It is not a truth, plagiarism, or academic-approval certificate.

The standard

The reader you would rather not have.

Your client reads with goodwill. Your team reads along. The other side reads to find something. NotaVera reads like the other side, only earlier.

i.

Eloquence proves nothing

The smoothest sentences are often the emptiest. NotaVera detects claims that need evidence as you write; otherwise it shows what is missing.

ii.

The counter-evidence doesn't disappear

You can ignore it. The other side cannot. It stands in the margin until you face it.

iii.

Overreach gets exposed

When a sentence claims more than the study supports, NotaVera proposes a version that holds.

iv.

A DOI is not proof

It proves something exists. Not that it carries your sentence. What fails that gets a warning instead of a footnote.

v.

Consensus is not a category

NotaVera distinguishes the dominant position, credible minority evidence, and speculation. A majority is not a mechanism.

vi.

The form is part of the examination

Text in the center, footnotes below, evidence in the margin. Whoever hides where things stand has a reason.

vii.

They have time

You do not. Whoever is paid for it reads slower.

viii.

A passport is not peer review

Write about dry fasting and you cannot get around Russian research. Most tools get around it and call that the state of the field. NotaVera ranks by method. Whether a country of origin is welcome is not a scientific category.

Atlas

The order behind your edge.

Important thoughts rarely announce themselves. What looks like a fragment today can be the core of a thesis years later. Or it disappears into a folder nobody opens again.

The map

Thoughts sit by kinship, not by date. What belongs together ends up side by side, even with years in between.

The space

The library shows your work as a sphere or as terrain. Chapters, claims, footnotes and sources are points of their own; fresh work glows, cold corners call you back.

The timeline

On a click, the space replays how your thinking grew: which thought arrived when, and what became of the fragments.

Obsidian stores what you wrote. NotaVera shows you which of it carries evidence.

What it costs

€12 a month. What a single citation that does not hold costs you, you know better than we do.

Full editor, counter-evidence in the margin, Evidence Weave, DOCX and PDF typesetting. Plus 560 processing units per calendar month. You are billed for real work, not for clicks: a paragraph costs a fraction of a unit, a chapter costs several.

Checking first costs nothing: 42 units a month, no card. Take a sentence whose answer you already know. There is no other way to judge a checking tool.

What you are right to ask

The objections, before you have to raise them.

We cite peer-reviewed literature only. What is NotaVera going to find?

That the source exists and is peer-reviewed was never the hard question. The hard one is whether it carries your sentence at exactly that reach. NotaVera marks the places where the claim goes further than the finding: a “necessarily”, an “all”, an effect transferred to a different population. That is where an opposing expert starts, and it almost never shows up in the bibliography.

Does your corpus cover my field?

NotaVera searches OpenAlex and resolves through Crossref. That is scholarly literature. Case law, technical standards, agency files and your internal data are not there, and NotaVera will not claim otherwise. For sources you supply yourself it still checks reach, boundary cases and counter-evidence.

What happens to a confidential document?

Zero Data Retention applies at the models: no training, no storage at the provider. Built and operated in the EU. You can export everything at any time, including after cancellation, and a plan change never removes access to what you have already written.

Can I hand the result to a third party?

That is what the Evidence Receipt is for: one page carrying the checked sentence, every source with its DOI and its role — supports, contradicts, or draws the boundary — plus a signature. You decide whether it becomes public, and you can revoke the link. It records evidence fit for a bounded claim and is explicitly not a certificate of truth, originality, or academic approval.

And when NotaVera is wrong?

Then the error is visible, with its source and locator beside it, and you refute it in a minute. Every finding names what it rests on. A tool whose statements cannot be recomputed would be the exact problem this one was built against.

Does NotaVera find everything?

No. NotaVera checks what is in OpenAlex and Crossref, and it checks the fit between your sentence and the source. It proves no claim, it guarantees no completeness, and at no point does it take the professional judgement off your hands. Anyone promising you that is selling you the same complaisance this tool was built against. What you get is a finding with a locator that you and a third party can recompute. One guarantee we do give: the other side will try.

The opposing expert is no better than you. They just have more time.
