For the Mac – from the App Store or directly from us

Your documents. Named, sorted, answerable.

Answers from your documents – with the source down to the page, and without any document leaving the Mac. DocUnderstand also names and sorts invoices, contracts and scans automatically and reads out the key data; every folder becomes a knowledge store.

No Apple account? The direct version is the same app; the first 500 operations are free. Order annual licence

When does the maintenance contract with Musterbau GmbH end, and what is the notice period?
The maintenance contract runs until 31 March 2027 and renews for one year unless it is terminated three months in advance – that is, by 31 December 2026 at the latest [1]. The 2025 addendum only changes the hourly rate, not the term [2].

Answer in 4.2 s · Apple Intelligence, no upload

Why not just use ChatGPT?

A general language model knows a lot about the world and nothing about your company. DocUnderstand turns that around: it knows your documents, backs every statement with a source and keeps everything with you.

Knowledge

Knows your documents

ChatGPT does not know your maintenance contract. DocUnderstand reads your folders – contracts, invoices, emails, scans – and answers from them, not from the internet. No invented figures.

Reliability

Every statement with its source

Every answer shows which file and which page it comes from; one click opens the passage. Your team checks in seconds instead of taking it on trust.

Confidentiality

Nothing leaves your company

With Apple Intelligence or a local model, everything stays on the Mac – no account, no upload, no passing on to third parties. A cloud model only if you set it up yourself.

Six working days that get shorter.

Not a feature list, but six situations from accounting, support, administration, practice, workshop and HR – and what DocUnderstand makes of them.

Accounting

The scanner drops 40 receipts into the folder.

DocUnderstand names each receipt, reads out date, issuer, net, VAT and gross and builds a table from it: for the whole folder, a subfolder or a search, as you prefer. Choose columns, check totals, save as Excel or CSV – ready for the accounting software or the tax advisor.

Before: a morning of retyping and renaming. After: one look at the totals row.

Five pillars. One app.

Filing, asking, writing, connecting and following along carry equal weight – and all of it runs entirely on your Mac if you want. Real recordings made with the sample stores the app offers to create on first launch.

Pillar 1

Tidying up, automatically

Drop in a file – the AI reads type, date and amount, gives it a telling name along with Finder tags, and pulls out the key figures.

  • Drop a file on the window or the Dock icon, whole folders too; a watched folder handles whatever the scanner drops in
  • Telling file names from content, date and document type – you set the rules per type
  • Key figures pulled out – invoice number, IBAN, due date – written beside the file as JSON or CSV if you like
  • OCR for scans and photos, barcodes and QR codes; photos become data – scene, people, objects, keywords, plus the description in three lengths and the camera metadata

Settings: document types
Document types — Keywords, tags and extraction per document type
Detail extraction for invoices
Reading out data — Which fields come out of invoices – freely adjustable

Your documents stay where they belong.

Invoices, contracts and medical reports are private. That is why the AI runs entirely on your Mac if you want – and nothing is transmitted unasked. Your files stay in your folders.

Ready without a download

Apple Intelligence

Apple's built-in AI model – runs immediately and entirely on the device.

Offline too

Local language models

Download selected models with one click; text recognition, embedding and search run locally as well.

Your choice

Ollama, LM Studio, OpenRouter

Your own server in the office or a cloud model with your own key – only if you set it up.

For your other programs, too.

The app comes with a local REST interface. Anything that speaks HTTP – FileMaker, Xojo, scripts, your own tools – can have documents recognized, ask questions and manage knowledge stores. OpenAI-compatible endpoints so existing tools work without rebuilding; the guide with examples sits right inside the app.

Terminal · recognize a document
curl -X POST http://localhost:8787/process \
  -H "Authorization: Bearer docunderstand-xxxx" \
  -H "Content-Type: application/json" \
  -d '{"filename":"Invoice.pdf",
       "mimeType":"application/pdf",
       "data":"<Base64>"}'
Terminal · asking, OpenAI-compatible

         "content":"When does the maintenance contract expire?"}]}'
# The answer with its sources – as with any OpenAI client

On your machine only

By default the interface listens on 127.0.0.1 only. Network access is a deliberate setting.

Two keys

One key for analysis and questions, a separate one for administration – they are never interchangeable.

No secrets handed out

The interface accepts passwords only from this Mac, and it hands out neither keys nor passwords.

Built for the Mac.

Your documents stay in your folders – DocUnderstand works where they already are.

The AI runs on the device – Apple Intelligence right away, local models with one click. No account, no cloud required.

Folders stay folders

A knowledge store is an ordinary folder with subfolders. Whatever you change or delete, the app follows – nothing is stored twice.

Several windows, menu bar

Open stores side by side, restored at the next launch. Watched folder and operation from the menu bar.

Passing it on

A knowledge store as a package for another Mac – with documents, or just settings and knowledge. Interface in 22 languages.

500 in total: Free gives you 500 operations in total – every automatically processed file, every question, every AI summary and every step while composing counts as one. 500 per month: On the subscription, questions, AI summaries and the steps while composing are limited to 500 per calendar month; processing is not. Each Mac counts separately. A failed request does not count.

Prices as listed on the App Store; they may vary by country. Subscriptions can be cancelled anytime, directly in the App Store. With Family Sharing you share Subscription and Pro with up to five other family members.

Without the App Store.

Not every company buys through Apple: the invoice has to go to the business, there is no Apple account, or the Macs are centrally managed. That is why DocUnderstand Pro is available as an annual licence directly from us – the same app, the same features, the same price.

Pro only

Annual licence

199 € /year

  • Everything in Pro: no limits on questions, knowledge stores or documents
  • Invoice from schubec GmbH, with VAT number on request
  • Unlocked with a licence file – just drag it in
  • No Apple account needed

How it works: you order, we send the invoice and the licence file. Drop the file onto the drop area in Settings › Plan – or double-click it in the Finder. The free tier and the subscription remain App Store only.

Try it first

The direct edition is the same app. The first 500 operations are free; you add the licence file later.

Download for Mac

macOS 26 or later · Apple Silicon · notarised by Apple

The direct edition keeps itself up to date: the app reports new versions at start-up and installs them once you agree – there is nothing to download by hand.

Order

We will get back to you with the invoice and the licence file, usually on the next working day. We need these details for nothing else.

Two apps, two jobs.

DocUnderstand and DocOversee share the same core: local AI, questions in plain language, every answer with its source. They differ in what happens to your files.

This site

DocUnderstand

The tool.

Your files stay where they are. DocUnderstand renames them, assigns tags, extracts data as JSON or CSV and serves other programs through the REST API and Shortcuts.

  • Renaming, tags, data extraction
  • REST API and Shortcuts
  • Mac only, also without the App Store

For anyone with a flow of files: offices, developers, automators.

Sister app

DocOversee

The document store.

Your papers move into projects with folders, versions, deadlines and a vault. Scan on iPhone, get the overview on iPad, run the hub on Mac – synced through your iCloud.

  • Projects, folders, versions, vault
  • Deadlines and payment overview
  • Mac, iPhone and iPad

For anyone who wants their documents organized and always at hand: families, practices, law firms.

Both apps can be used side by side.

Frequently asked questions

What leaves my computer?

With Apple Intelligence or a local model: nothing. Text recognition, search, embedding and answering all run on the Mac. Only if you yourself set up a server or a cloud model with your own key do text excerpts go there – just the passages needed for the question, never your whole folders. Nothing goes to schubec: no content, no usage data; crash reports only if you agree at first launch.

What does a cloud model cost, if I use one?

The provider bills that by usage, not us – from fractions of a cent to a few cents per question, depending on the model. DocUnderstand shows the cost of each request in the log, so you keep track. With a local model or Apple Intelligence, a question costs nothing.

What is the difference from Spotlight or Finder search?

Spotlight finds files in which a word occurs. DocUnderstand answers the question: it understands what is meant, even without the exact word, summarizes the matching passages from several files and names the page. And it can write – draft replies, summaries, translations, documents from templates.

Is this GDPR-compliant?

With local processing, personal data stays on your device – there is no processing by us and no processor you would have to engage. If you use a cloud model, your contract with that provider applies; you decide which one and for which stores. The log of each request shows which passages were transmitted.

What is a knowledge store?

An ordinary folder on your Mac that DocUnderstand reads and watches – with all its subfolders. You put files in as you always have; the app reads them, summarizes them, tags them and answers questions about them. There is no second filing system inside the app: whatever you change in the Finder, DocUnderstand follows.

What is the difference to DocOversee?

DocOversee is the document store: your papers move into projects with folders, versions, deadlines and a vault – on Mac, iPhone and iPad, synced through your iCloud. DocUnderstand is the tool for files that stay where they are: rename, tag, extract data, serve other programs through the REST API and Shortcuts – Mac only. Both share the same core and can be used side by side. Go to DocOversee ↗

Are my documents safe?

Yes. With Apple Intelligence or a local language model, no document leaves your Mac; text recognition, embedding and search run locally as well. Data is transmitted only if you set up a server or a cloud model yourself.

Do I need an internet connection?

No. Once a local model is downloaded or Apple Intelligence is available, DocUnderstand works entirely offline. You need the internet only to download models and for cloud models, if you use any.

Which files does DocUnderstand understand?

Read for their content: PDF, Word (DOCX), Excel (XLSX), PowerPoint (PPTX), Pages, Numbers, Keynote, OpenDocument, text, Markdown, RTF, HTML, CSV, JSON, emails (EML, MSG) with attachments, images with text recognition and image description, and web pages. The older .doc and .xls formats are not read. Any other file may still sit in the folder – it is found by name, keyword and note.

How do I know the answer is right?

Every statement carries a source, and one click opens the page it quotes. And every answer has a path: which passages were found, what the model received, how long it took. If nothing in your documents fits, the app says so instead of inventing something.

Can I share my subscription with my family?

Yes. Subscription and Pro support Apple's Family Sharing: once it is set up in your Apple Account settings, up to five other family members use your subscription without buying their own – each on their own Mac and with their own documents.

What happens when a quota or a limit is reached?

Nothing is deleted or locked – your knowledge stores and documents stay readable and searchable. Only nothing new is added until you take out a subscription, move to Pro, make room, or the next month begins in your subscription. A failed request, by the way, does not count.

Can I buy without the App Store?

Yes, Pro is available as an annual licence directly from us – €199 a year, the same as in the App Store. You order through the form, receive the invoice and the licence file, and drag the file into the app. The free tier and the subscription stay in the App Store, because billing there is handled by Apple.

How does the direct edition differ?

In features, not at all. It is the same source code, notarised by Apple; the plan is simply unlocked with the licence file instead of your Apple account. That is why there is no Family Sharing there: it belongs to the App Store. In return, the direct edition needs no Apple account and can be rolled out on managed Macs. It updates itself; the App Store edition gets its updates through the App Store.

Can I switch between the App Store and the direct version?

Yes, in both directions. Both versions are the same app and share database, documents and settings on your Mac; after switching, everything is there again. A newer version does not lock out the older one: the database is only extended, never restructured – in the older version you merely miss the newer features. Only the unlock does not carry over: in the App Store your subscription or Pro counts with Apple, in the direct version the license file. Install only one of the two at a time; both live as “DocUnderstand.app” in Applications.

What do I need for this?

macOS 26 or later and a Mac with Apple Silicon. Apple Intelligence runs without a download; local language models need 2 to 10 GB of disk space depending on their size, and memory to match.
