Common questions

Can I use ABBYY or KlearStack on my phone to scan receipts?

No, neither tool has a mobile app. For scanning receipts on your phone, you'd need a separate app like Adobe Scan or Microsoft Lens, then upload the files to these platforms.

Which tool is easier to set up for a small business with no technical staff?

KlearStack is easier because it works without templates and offers a 30-minute pilot. ABBYY typically requires professional services and technical expertise to configure.

Is ABBYY better than KlearStack for invoice processing?

Both are strong, but KlearStack is better for invoice processing if you want fast, template-less setup and straight-through processing. ABBYY is better if you also need process mining and have a larger budget.

Do these tools work with scanned PDFs and handwritten text?

Yes, both handle scanned PDFs and have OCR capabilities. ABBYY has a longer track record with handwritten text recognition, but KlearStack's DROC.ai engine also supports it with high accuracy.

Which tool is more affordable for a regular person or freelancer?

Neither is affordable for a regular person — both are enterprise-priced with custom quotes. For personal use, consider simpler tools like Adobe Acrobat Pro or online OCR services.

KlearStack wins for everyday business users who need fast, template-free document processing; ABBYY is for large enterprises with deep pockets and technical teams.

If you're a small or mid-size business that just wants to automate document processing without hiring a consultant, start with KlearStack's free pilot. ABBYY is powerful but only worth it if you have the budget and team to handle its complexity.
