What exactly does Klaaro do?

Klaaro is a document AI that turns unstructured documents into structured, ready-to-use data. Upload invoices, offers, CVs, emails, reports or contracts — and Klaaro automatically extracts the relevant information and organizes it into clean, usable data. AI document processing without manual copy-paste, templates or a setup project.

Do we need technical skills to use Klaaro?

Klaaro is aimed first at developers, who integrate it into your systems. From there, the main beneficiaries are business teams, who need no technical skills at all to use it. Klaaro then works reliably in the background, processing all the documents that would otherwise have to be reviewed and handled manually.

What types of documents can Klaaro process?

Klaaro works with PDFs, Excel files, Word documents, PowerPoint files, emails, and scanned documents (via OCR). Typical use cases include invoices, offers, CVs, inquiry emails, reports and contracts.

Can Klaaro convert handwriting to text?

Yes. Klaaro’s OCR reads handwriting as well as printed text, from scans and phone photos alike, and turns it into machine-readable text and structured fields. Values it is unsure about, such as a hard-to-read digit, are flagged for review instead of guessed.

Can Klaaro extract text and data from PDFs?

Yes. Klaaro reads digital PDFs and scanned PDFs alike: OCR text recognition turns every page into text, and the AI then pulls out the fields you need, like supplier, amount or due date, even across hundreds of pages.

Can Klaaro process documents in batch?

Yes. Upload many files at once in the app, or send them through the API, the n8n node or the TypeScript and Python SDKs. Klaaro runs OCR and extraction on every document in the batch and you review the results in one place.

How accurate is the data extraction?

Klaaro uses modern AI models to understand document context, not just text. Accuracy depends on document quality and structure, but for standard business documents, extraction quality is typically very high. For critical workflows, results can always be reviewed before further use.

Is Klaaro GDPR compliant?

Yes. Klaaro is fully GDPR compliant and hosted in the EU. Your data is never used to train public models. You remain the owner of your data at all times.

Where is our data stored?

Your data is securely stored in EU-based cloud infrastructure with enterprise-grade security standards. Access control, encryption and role-based permissions ensure your documents stay protected.

What happens if our document layouts change?

Nothing. Unlike rule-based automation tools, Klaaro understands document content and context. It does not rely on fixed templates, so it can handle layout variations without breaking.

Can we export or integrate the data into our existing systems?

Yes. You can export structured data to Excel or CSV, connect via API, or integrate with your existing BI tools and workflows. Klaaro is designed to fit into your existing tech stack.

How long does it take to get started?

Minutes. There is no implementation project. No workshops. No configuration. You can upload documents immediately and see structured results within seconds.

Your business is growing.
So is your paperwork.

Documents pile up faster than you can hire
Every new order brings invoices, delivery notes and forms. Finding and onboarding new people takes months – the pile doesn’t wait.
Your best people are stuck typing
Skilled staff copy values from PDFs into the ERP, field by field, day after day. One transposed digit, and the error travels through every system.
No two documents look alike
Scans, phone photos, handwriting, tender packs or BoQs with hundreds of pages. This heterogeneity breaks rigid OCR templates and burns ChatGPT & co.’s token limits.

The consequence

Your company wants to grow.
Your processes won’t let it.

As long as workflows hang on manual work that should have been automated long ago, every new order becomes a bottleneck instead of an opportunity.
