EryonOne, the document review platform

Full walkthrough

The EryonOne journey, end to end

From signing in to the annotated report.

01 How it works

Four steps, and you keep the call

EryonOne asks the questions, you decide. Nothing is charged before you confirm.

1

You upload

PDF today. Word and PowerPoint are coming next.

2

Eryon analyses

The axes run in parallel. Every finding is sourced.

3

You arbitrate

Accept, dismiss, then follow the fix through (open / done).

4

You export

Report as PDF, CSV or interactive HTML.

02 The review axes

Four readings of the same document

Regulatory, scientific, formatting, linguistic. Each axis runs in parallel and returns its own findings to arbitrate. You only pay for the ones you tick.

A fifth axis, internal consistency, is added automatically as soon as you select the regulatory or the scientific axis: it catches the same fact stated differently in two places in the document.

Regulatory

Compliance with the applicable external texts. Today: MDR and IVDR by device class, ANSM doctrine, Directive 2001/83/EC, the French Public Health Code and the conditional texts that apply to your file. You add your own requirements.

Scientific

Claims are tied to the evidence you supply. Gaps, contradictions and missing evidence are flagged for you to arbitrate.

Formatting

Heading hierarchy, expected sections, visual consistency and adherence to your style guide.

Linguistic

Ambiguous wording, undefined jargon, room for misreading. Clarity and tone suited to the reader.

What you upload

For now, review is available on PDF. Word and PowerPoint are coming next.

What you get back

The report comes out as PDF, CSV or interactive HTML, whichever you need.

03 Before / With

What changes in a day of reviewing

A good reviewer finds the errors. An excellent reviewer helps you fix them. EryonOne does both, at machine pace.

Reviewing by hand

One pass per requirement, over and over.
Sources to track down and cross-check manually.
No structured record of the decisions taken.
Risk of an omission or an inconsistency between versions.
Heavy mental load on dossiers that live for months.

Reviewing with EryonOne

Findings sorted by axis, read in parallel.
Evidence quoted next to every finding.
A suggestion and a reasoned opinion on each one.
Every decision recorded in the file: user, timestamp, optional comment.
Exportable report, ready to defend an arbitration.

04 Who it is for

What changes, depending on your role

Four profiles, four different gains on the same document.

Regulatory Affairs

Fewer replies to the notified body

Missing mandatory statements, unsourced claims and inconsistencies between the technical file and the instructions for use are caught before submission. Fewer reworks, fewer round trips.

Medical / scientific

More time for the judgement call

No more half a day spent matching a figure to its source. EryonOne puts the data next to the evidence, and you arbitrate on substance.

Medical communications

Tighter promotional material

Every promotional claim is checked against the summary of product characteristics and the ANSM doctrine. CE markings, notified bodies and cross-references to the leaflet are checked systematically.

Quality / SOP

Internal consistency of the document

Inside a single document, you catch a fact stated differently in two places, or a section that contradicts another. The internal consistency of the document becomes measurable.

05 Coverage

We tell you what we cover, and what we do not

EryonOne does not claim to know everything. The exact scope of each framework (document types, sections, requirements checked) is published on the Frameworks page.

See the full coverage

Active

Today: MDR and IVDR by device class, ANSM doctrine, Directive 2001/83/EC, the French Public Health Code and the conditional texts that apply to your file. You add your own requirements.

Planned

Coming next: FDA (integration in progress), ISO 13485, EMA, ICH. Until a text ships, EryonOne does not check that area.

06 AI & data

Your documents, your own AI access if you wish

By default, your documents are processed by Claude (Anthropic) under an Eryon contract, and never used to train a model. If your organisation already has its own access to an AI provider, we can use it for your account: let's discuss it before you start.

✦

No training

Your documents serve your review and nothing else. Nothing is used to train a model, neither at Eryon nor at the AI provider.

⚡

Zero Data Retention in progress

We are contracting it with the AI provider. Until it is signed, we do not present it as settled.

07 Pricing

The price shows first. Always

Billed per review: based on the page count, the axes you select and, for the scientific axis, the number of pieces of evidence to check. One at a time, by credit pack or by monthly subscription. The estimator on the Pricing page works out the exact amount before you commit to anything.

Price shown before launch

Nothing is charged until you confirm. The price shows in credits before every launch; the conversion into euros is on the Pricing page.

One at a time, by pack or by subscription

Pay for one review at a time, top up a credit pack, or switch to a monthly subscription if your volume is steady. No minimum imposed outside a subscription.

Volume discount

The marginal rate drops automatically as the document gets longer. For a volume or specific contractual arrangement, talk to us.

What you ask us before your first upload

Which formats can I run a review on?

For now, review is available on PDF. Word and PowerPoint are coming next. The report comes out as PDF, CSV or interactive HTML, whichever you need.

Which regulatory frameworks are actually covered?

Today: MDR and IVDR by device class, ANSM doctrine, Directive 2001/83/EC, the French Public Health Code and the conditional texts that apply to your file. Coming next: FDA (integration in progress), ISO 13485, EMA, ICH. You add your own requirements. Until a text ships, EryonOne does not check that area.

Can the AI be wrong about a point it raises?

Yes. That is exactly why every finding comes with its source quoted: if the AI misreads a text or invents evidence, you see it and dismiss it in one click. The final decision stays with your experts.

Are my documents used to train a model?

No. Your documents serve only the review you asked for. Nothing is used to train a model, neither at Eryon nor at the AI provider. Zero Data Retention is being contracted; the detail is on the Security page.

What exactly does EryonOne check?

Four axes per document: regulatory (the applicable external texts: MDR and IVDR, ANSM doctrine, Directive 2001/83/EC, the French Public Health Code, plus your own requirements), scientific (traceability to the evidence you supply), formatting (structure, style guide) and linguistic (tone, clarity). Every finding is tied to its passage and its source; the decision stays human.

How does EryonOne compare to a human reviewer?

EryonOne assists. It identifies the points to arbitrate and suggests corrections, but the final decision stays with your experts. The report is working material, not a sign-off.

How long does a review take?

A few minutes for a short document, longer for a full technical file. The status of the run is visible live in the project space.

How does billing work?

The price shows in credits before every launch; the conversion into euros is on the Pricing page. No charge before you explicitly confirm.

Upload your first document

An account is all it takes to run a review. Your first review is free, to be used within 30 days, and the price shows in credits before every launch.
