Why Erynva

Stop opening PDFs
just to name them.

Turn cryptic scans and downloads into useful filenames. Erynva combines platform-native text recognition with local AI to understand what each document is about.

01

Works where your files live.

Right-click selected PDFs in Finder or File Explorer, or drag them directly into the Erynva app.

02
DateSenderRecipientSubjectReferenceTypeAmountLocationStatus

Your names, your rules.

Choose the fields, separators and date format. Save presets for the documents you handle most.

03

2Needs review

You stay in control.

Review anything uncertain before it becomes permanent. Corrections improve future results and stay local too.

How it works

From messy to meaningful
in three simple steps.

  1. 01

    Choose your PDFs

    Select files in Finder or File Explorer, or drop them into the app.

  2. 02

    Erynva reads them

    Local OCR and AI extract the fields in your chosen preset.

  3. 03

    Review and rename

    Approve the clear filenames, then fix only what needs attention.

Privacy by design

Your documents
never leave your computer.

OCR runs through Apple Vision on macOS or Windows OCR on Windows. Document understanding runs through a downloaded local model. Erynva does not send your PDFs or extracted text to a cloud API.

One app, all your documents

Built to fit the way
your business files work.

Start with a preset, then make it yours.
