Amazon Textract AnalyzeExpense vs Diffbot

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.

Diffbot uses AI models to turn unstructured web content into linked knowledge through a set of data services. Extract classifies a page and returns structured JSON using a standard page type and ontology. Crawl starts with seed URLs, visits sites, and collects extracted pages in structured datasets. Natural Language resolves entities, relationships, coreferences, salience, and sentiment in plain text. The Knowledge Graph supports structured queries about companies, people, news, and other public web entities. Web Search provides an API and a self-hostable search index for a machine or cloud, including offline use; Diffbot says closed media sites such as Facebook, Reddit, LinkedIn, and Instagram are generally off limits. Python and TypeScript libraries and agent skills are listed as interfaces. The free plan provides 10,000 credits per month, all four APIs, and up to 5 requests per minute without a credit card. It returns a 429 Quota Exceeded response after the credit allowance or rate limit is reached, with quotas resetting at the start of each billing period. Startup costs $299 a month. Diffbot lists API, self-hosted, and web platforms.
