AI Viewz OCR vs. Top OCR Services: Features, Performance, and Cost Comparison

Optical Character Recognition (OCR) is a transformative technology for digitizing documents, automating data extraction, and enabling seamless workflows across industries. As an ML Engineer, I’ve evaluated numerous OCR services to identify the best fit for various use cases. In this post, I compare AI Viewz’s OCR service and its two variants—Internal Build (using Tesseract and open-source technologies) and Gemini 2.5 Pro-powered—with leading OCR services: Google Cloud Vision API, Azure OCR, AWS Textract, Mindee OCR, Tesseract OCR, EasyOCR, DocTR, PaddleOCR, Surya OCR, and Microsoft TrOCR. The comparison focuses on features, performance, use cases, and costs, highlighting AI Viewz’s cost-effectiveness due to its token-based Gemini API pricing.

Overview of AI Viewz OCR

AI Viewz provides a versatile OCR platform for extracting text from images, PDFs, and scanned documents, supporting languages like Hindi, Urdu, and English. It offers two variants:

• Internal Build: Built on Tesseract and other open-source technologies, this variant prioritizes affordability and local processing.
• Gemini 2.5 Pro-powered: A wrapper around Google’s Gemini 2.5 Pro model, leveraging token-based pricing for cost-efficient, high-accuracy text extraction. AI Viewz emphasizes privacy (no data storage), fast processing, and an API for integration, making it suitable for finance, healthcare, education, banking, and content creation.

Comparison of OCR Services

Here’s a detailed comparison across key dimensions: features, accuracy, language support, speed, use cases, and integration.

1. Features

Cost Comparison

Costs are a critical factor in choosing an OCR service. AI Viewz’s Gemini 2.5 Pro variant leverages token-based pricing via the Gemini API, which is typically lower than other generative AI services like OpenAI’s API. Below is a cost comparison based on available data and assumptions for AI Viewz (since exact pricing isn’t provided in the document).

• AI Viewz Internal Build: Free for local processing (Tesseract-based), with only hardware costs. Ideal for budget-conscious users.
• AI Viewz Gemini 2.5 Pro: Token-based pricing via Gemini API, likely $0.0001–$0.0005 per 1,000 tokens for text extraction (based on typical Gemini pricing). This is significantly lower than generative AI services like OpenAI API ($0.01–$0.03 per 1,000 tokens) or Anthropic’s Claude ($0.003–$0.015 per 1,000 tokens). A single page typically requires 1,000–5,000 tokens, estimating $0.0001–$0.0025 per page.
• Google Cloud Vision API: $1.50 per 1,000 pages (up to 5M pages), then $0.60 per 1,000 pages. New users get $300 credit (~200,000 pages).
• Azure OCR: ~$1.00 per 1,000 pages (Read API), slightly cheaper than Google. Pricing varies by region and feature.
• AWS Textract: ~$1.50 per 1,000 pages for text extraction, higher for forms/tables ($15–$50 per 1,000 pages).
• Mindee OCR (DocTR): Free (open-source), with only hardware costs. Commercial Mindee APIs start at ~$0.50 per 1,000 pages for basic extraction.
• Tesseract OCR: Free, open-source, with only hardware costs.
• EasyOCR: Free, open-source, with only hardware costs.
• DocTR: Free, open-source, with only hardware costs.
• PaddleOCR: Free, open-source, with only hardware costs.
