Mistral AI, Landing AI, or Docsumo Document AI - Which One Overrules the OCR Benchmark

TL;DR

1. Docsumo leads the OCR race by outperforming Mistral and Landing AI in layout preservation, accuracy, and speed across 120 real-world documents.
2. Mistral OCR underperforms, showing high hallucination rates, missing table content, and failing to process fine print or images effectively.
3. Landing AI offers better accuracy than Mistral; however, its paraphrased outputs and label mismatches impact data reliability.
4. Docsumo’s native OCR maintains document integrity, accurately extracts structured data, and delivers quick results suitable for production-grade workflows.
5. Docsumo strikes a balance between speed and precision, processing pages in under 10 seconds with 84.8% information extraction accuracy using GPT-4.

Document AI is booming, and everyone’s talking about the latest tools promising intelligent data extraction from PDFs, invoices, bank statements, and more. With Mistral OCR and Landing AI’s Agentic Document Extraction gaining attention, Docsumo decided to test them side-by-side.

The goal? Evaluate how these tools perform in real-world scenarios based on three key criteria: Text extraction quality, information extraction accuracy and processing speed. 

Docsumo ran a controlled test with 120 documents, ranging from invoices to forms, and had three independent reviewers analyse the results. Here's what they found, broken down into simple questions and answers.

1. What is OCR, and why does it matter for document processing?

A: OCR stands for Optical Character Recognition. It helps convert scanned documents into editable and searchable data. Businesses need to automate workflows, reduce manual data entry, and ensure data accuracy. 

2. How was the performance of Mistral, Landing AI, and Docsumo evaluated?

A: Each system was tested across 120 real-world documents. Reviewers checked how well the tools:

• Preserved layout
• Extracted accurate structured data
• Maintained speed in processing

You can explore the comparison benchmarks here.

3. Which tool offered the best accuracy in text extraction?

A: Docsumo’s native OCR preserved document layout and every word in its exact position, making it ideal for downstream tasks. In contrast, Mistral often missed text entirely or hallucinated unrelated content. Landing AI struggled with paraphrasing instead of exact extraction. Want to see a real example? Watch the comparison video to see how each tool performs side by side.

4. Did any of the tools hallucinate or generate incorrect content?

A: Yes, Mistral OCR frequently misread unclear or low-resolution scans, generating random text. This is a critical issue for businesses relying on OCR for compliance or financial data.

5. Which OCR system performed best in terms of structured data extraction?

A: When tested using GPT-4o:

• Mistral scored 63.6%
• Landing AI scored 78.6%
• Docsumo scored 84.8%

This level of precision is fundamental when extracting financial or legal data. 

6. How fast is Docsumo compared to Mistral and Landing AI?

A: Speed-wise:

• Mistral: <2 seconds per page (fast but inaccurate)
• Landing AI: 1–2 minutes per page (accurate but slow)
• Docsumo: <10 seconds per page (optimal balance)

This makes Docsumo ideal for production-grade workflows.

7. Why did Mistral fail in document layout preservation?

A: Mistral often treated sections of documents as images, skipping text extraction. It also failed with table structures, small fonts, and fine print. For businesses, this creates blind spots in data extraction, something Docsumo handles well.

8. What common issues were found with Landing AI's Agentic Extraction?

A: Landing AI over-described fields (summarised instead of extracted), misread vertical numbers, and mislabeled fields. This can lead to data inconsistencies, especially in documents such as bank statements or tax forms. 

9. How did reviewers score overall tool preference?

A: Out of 120 cases:

• Docsumo was preferred in 116
• Landing AI in 4
• Mistral in 0

This strong preference shows Docsumo’s consistent reliability across document types. 

10. What’s the best OCR tool for businesses looking to scale?

A: Docsumo offers the best mix of speed, accuracy, and usability. It's built for real-world, production-grade workflows and supports seamless integration into your existing systems. 

Final Thoughts

While AI-based OCR tools like Mistral and Landing AI show potential, their current limitations in layout preservation, hallucination control, and structured data accuracy pose real challenges for business-critical workflows. In contrast, Docsumo’s balance of precision, speed, and structure makes it the most dependable choice in real-world conditions, especially when accuracy and scale matter.
