Baidu OCR vs Cloudmersive OCR API

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.

Cloudmersive OCR API converts scanned documents and photos of documents or receipts into text using deep-learning OCR. It lists support for more than 90 languages, including English, simplified and traditional Chinese, French, Spanish, German, and Italian. For document and receipt photos, the API can locate the item and correct skew or rotation before recognition. Receipt extraction can return business name, address, phone number, total, and date. Image and photo endpoints offer Basic, Normal, and Advanced recognition modes; an OCR task may consume multiple API calls, including when processing a multipage PDF. The free tier costs nothing and includes 600 calls monthly, one call per second, and a 3.5 MB maximum file size. Using a free-tier key with OCR endpoints requires adding a credit card, and the free tier allows one simultaneous request. Paid plans start at $19.99 a month. Deployment options include public cloud, dedicated managed instances, private cloud, on-premises, PaaS, and government cloud. Cloudmersive says its stateless APIs do not retain payload data after a transaction and its endpoints use HTTPS with TLS 1.2 or later.
