Amazon Textract AnalyzeExpense vs Baidu OCR

Amazon Textract AnalyzeExpense extracts financial text and data from invoices and receipts through an API or web service. Results can include grouped line items and summary fields such as purchased items, prices, receipt headers, and vendor names. The API can normalize field names and column headers to help downstream applications compare documents. It can also identify vendors from logos and extract items, quantities, and prices when those details have no labels or column headers. Supply documents as image bytes or an Amazon S3 object; AWS advises PDF, JPG, or PNG files, and invoice and receipt processing is English only. AnalyzeExpense processes synchronously. Asynchronous invoice and receipt analysis uses StartExpenseAnalysis and GetExpenseAnalysis. The listed rate is $0.01 per page for the first 1 million pages per month in US West (Oregon), then $0.008 per page; custom high-volume pricing is available. New AWS customers can use the Free Tier for three months, up to 100 pages per month. AWS says inputs may be used to improve Textract and related AI technologies, with an Organizations opt-out policy.

Baidu OCR recognizes text in images, including printed and handwritten material, and offers more than 70 capabilities for different industries and scenarios. Its structured recognition options cover identity and bank cards, business licenses, household registers, passports, and transport documents. Baidu states that general text recognition and recognition of major certificates and receipts exceed 98% accuracy. Organizations can connect to the public cloud through online APIs or HTTP SDKs. An offline SDK can be integrated into mobile devices such as phones, cameras, and law-enforcement recorders, while private deployments can run on local servers or a private cloud. The private-deployment software is packaged as Docker containers and supports CPU or GPU environments and domestic operating systems. Baidu says it stays within a dedicated network without uploading data to the public internet. The product has no free plan but lists a free test allowance after real-name verification: 1,000 monthly calls for personal accounts or 2,000 for enterprise accounts using General OCR Standard. A shared resource package is listed at 330 CNY, paid once.
