FABER

Terms of Use

What Faber does with what you drop on it.

Version 2026-10-fab-2

Beta. These terms govern access to Faber during its beta phase. The version above is recorded when you explicitly accept it.

1. What Faber is

Faber's product is Fab, and these terms cover all of it: its work on technical drawings and its work in CAD.

• On drawings, Fab balloons dimensioned technical drawings. You drop a PDF, a scan or a photograph of a drawing; every characteristic on it is numbered on the drawing itself; and you download two deliverables — the ballooned sheet an inspector prints, and the inspection workbook (XLSX or CSV) they type measurements into.
• In CAD, Fab turns a description and the files you attach into editable CAD. An automated engineering agent writes and runs a parametric model to reproduce what you asked for, and you download the result as a STEP file.

One Faber account, one sign-in and one balance of credits cover all of it.

It is operated by Faber AI, a French société par actions simplifiée (SAS), registered with the Paris Trade and Companies Register under number 103 155 172, with its registered office at 231 rue Saint-Honoré, 75001 Paris, France ("we", "us").

2. Your account

Signing in is through Google or Microsoft. We receive the verified email address, the name and the account identifier that identity provider gives us, and use them to identify you, to count your runs and to contact you about the service. We also record which version of these terms and of our privacy notice you accepted, and when.

Runs are metered in credits, and one balance is spent by a run on a drawing or in CAD alike. A new account is given a starting balance; a run that exhausts it finishes rather than stopping half-built, and the next run is refused until there is more. Credits are a unit of account for usage, not currency, and they are not refundable or transferable except as required by law. We may change that grant, and we may suspend or close an account that is being used to attack the service or to work around its limits.

3. Your files, and where they go

When you drop a file, it:

• is uploaded to our servers in France (Microsoft Azure, France Central), where the run happens;
• has the part of it the model must see sent to the model provider that produces the result, because reading your drawing or your description is what the service does. Fab's hosted agent uses OpenAI models hosted by Microsoft's Azure AI service for drawings and CAD. Google's Gemini API is also used for auxiliary tasks and tasks that use Gemini. In configurations that offer a personal ChatGPT connection, choosing it sends the agent's context directly to OpenAI under your account's terms and data controls; this option is not offered on the current public hosted service. Model processing may take place outside the European Union; the privacy notice explains the recipients and processing locations;
• is stored with your account, together with everything produced from it;
• is kept while you use it and purged 90 days after it was last opened — one rule, for drawings and CAD alike. You may delete a project, and everything produced from it, at any time, and that deletion is not reversible.

We do not use your files to train models, ours or anyone else's. We do not sell them and we do not make them available for advertising or prospecting.

On the hosted service, a record of every run is kept — what the model was shown, what it read and the steps it took — and is how we correct the product where it gets something wrong. It is kept in storage Faber itself operates; no analytics provider receives it. In other installations, recording depends on the diagnostic configuration. The privacy notice explains what these separate records contain and how to request deletion.

4. Your files

You confirm that you have the right to upload the files you submit; a drawing is often a customer's part, and holding that right is yours to check. You retain ownership of your files and of what Faber returns from them. You grant Faber a non-exclusive, worldwide, royalty-free licence to store and process those files for as long as we hold them, for the sole purpose of running the service for you and of securing and supporting it.

5. Availability and liability

The service is provided as is, with no warranty of availability, accuracy or fitness for any purpose. A beta service may be interrupted, changed or withdrawn without notice, and a run may fail.

What Faber returns is produced by an artificial-intelligence model and can be wrong — a misread figure, a missed characteristic, an invented one, a tolerance in the wrong unit, a model that is not the part — and a result that is wrong looks exactly like one that is right. A ballooned sheet, an inspection workbook and a CAD model are a proposal, not a deliverable: they are to be checked by a competent person, against the drawing or the description they were made from, before anything is measured, quoted, manufactured, accepted or rejected on them. You remain responsible for that verification and for any decision taken on the result.

To the fullest extent permitted by law, we are not liable for any indirect or consequential loss, and in particular not for the cost of parts manufactured, accepted or rejected on the strength of output you did not verify. Nothing here excludes liability that cannot lawfully be excluded.

6. Changes, and the law

We may update these terms. The version string on this page changes with them, and your account records the version you accepted. We will require an explicit acceptance of a new version before access resumes.

These terms are governed by French law. Any dispute will be submitted to the courts having jurisdiction under applicable law.
