Airparser vs Diffbot

Airparser turns emails, PDFs, and other documents into structured fields you define. Its text and vision language models plus AI OCR handle typed text, scans, and handwriting, with recognition in more than 60 languages. Low-confidence results can wait for human review, correction, and approval before export. Parsed information can be downloaded as Excel, CSV, or JSON, or sent to webhooks and services including Zapier, Make, n8n, Google Sheets, and Airtable. Python post-processing is included in plans, and an AI code assistant can draft and test code from plain-language instructions. Airparser works through the web and an API, with workflow routing and cloud deployment. Each parsed email, document, or PDF page consumes one credit, and unused credits expire at the billing period’s end. A Trial plan is listed at free with 20 credits/month and 30 days’ retention. Paid plans start at $33 a month, billed annually.

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.
