## Airparser

Airparser is a document data extraction platform built around large language models. Instead of building rigid templates or regex rules, you simply describe the data points you want — invoice totals, candidate contact details, order numbers, contract clauses — and the parser returns them as consistent JSON. It handles PDFs, scanned images, DOCX, TXT, HTML, EML emails, and even handwritten notes, using OCR and multi-engine fallback to keep accuracy high across 60+ languages.

The platform is designed for production workflows rather than one-off conversions. Incoming emails can be forwarded to a dedicated inbox, files can be uploaded manually, or documents can be submitted via REST API and automation platforms. Once extracted, a post-processing step lets you reshape data with Python (or have an AI assistant draft the code) for formatting, merging fields, or conditional logic. Webhooks and integrations push the finished records straight into CRMs, spreadsheets, and databases.

Airparser emphasizes compliance and reliability, with GDPR-ready handling, editable schemas, validation rules, and a growing human-in-the-loop review feature for verifying results before export. It also ships an MCP connector so AI agents like Claude and ChatGPT can read inboxes, schemas, and documents. Pricing scales by credits, where one credit equals one parsed page or document.

**Pricing & Plans:** Free trial with 20 credits per month and no credit card required. Paid plans start at $33/month (Starter, 100 credits) and scale through Growth ($49, 500 credits), Business ($149, 2,000 credits), and Premium ($249, 5,000 credits). Annual billing saves about 17%. Higher-volume pricing is available on request.

- **LLM extraction without templates:** Describe the fields you need in natural language and Airparser extracts them into consistent JSON from PDFs, emails, images, and Office documents.
- **Email inbox parsing:** Forward messages and their attachments to a dedicated address, and Airparser turns each one, plus anything attached, into structured data automatically.
- **Python post-processing:** Clean, reshape, enrich, or filter extracted values with Python code, or let the AI code assistant generate it from a plain-language description.
- **Webhooks, API, and integrations:** Push parsed records to 7,000+ apps through Zapier, Make, and n8n, or connect directly with REST APIs, webhooks, Google Sheets, Airtable, and Excel.
- **OCR and multi-engine fallback:** Parse scanned documents, images, and handwritten text in 60+ languages, with fallback engines to keep results reliable on hard inputs.

**Strengths:** Schema-free setup: describe the fields you want instead of building templates; Handles emails, PDFs, scans, images, DOCX, and handwritten text in one tool; Strong automation footprint with webhooks, REST API, Zapier, Make, and n8n; GDPR-compliant processing with editable schemas and validation rules

**Limitations:** Credit-based pricing can add up quickly on high-volume document flows; Unused credits expire at the end of each billing period; Some advanced output shaping still benefits from Python knowledge

## BigModel

BigModel is Zhipu AI's developer-facing platform, offering API access to the company's GLM series of large language models and a broad set of multimodal capabilities. Instead of juggling separate vendors, teams can call text generation, vision-language understanding, OCR, speech recognition, speech synthesis, image generation, and video generation endpoints from one account and one set of credentials.

Beyond raw model access, the platform targets application builders. It includes an agent framework, MCP service support, knowledge-base tooling for retrieval-augmented generation, model fine-tuning workflows, and a model playground for quick testing in the browser. There are also adjacent offerings such as an AI coding assistant and visual/low-code building experiences aimed at teams that want to ship without heavy ML engineering.

For organizations with stricter requirements, BigModel supports private instance deployment and on-premise options, alongside token-based pay-as-you-go and enterprise contracts. This makes it a fit for both individual developers prototyping on a budget and enterprises that need data to stay inside their own infrastructure.

**Pricing & Plans:** BigModel follows a freemium, token-based model: new users typically receive free trial credits, then pay-as-you-go for API usage by tokens consumed. Larger volumes, private instance deployment, and on-premise installations are arranged through contact-for-pricing enterprise agreements. Always confirm current rates on the official pricing page.

- **GLM text and multimodal APIs:** Unified access to GLM large language models plus vision, OCR, speech, image, and video endpoints through one account.
- **Agent and MCP support:** Build tool-using agents and expose or consume MCP services to connect models to external systems.
- **Knowledge base and RAG tooling:** Create managed knowledge bases and retrieval pipelines so models can answer with your own documents.
- **Fine-tuning and playground:** Tune models on your data and prototype prompts interactively in the browser before shipping.
- **Private and on-premise deployment:** Run models in a private instance or on your own hardware for data-residency and compliance needs.

**Strengths:** Broad model coverage, from LLMs to vision, speech, and video, under one platform; Officially backs the GLM family, so model documentation and updates are first-party; Supports private and on-premise deployment for strict data requirements; Includes agent, knowledge-base, and fine-tuning tooling beyond raw API access

**Limitations:** Pricing and documentation are primarily Chinese-first, which can slow English-only teams; Some enterprise capabilities require sales contact rather than transparent self-serve pricing; Token costs can grow quickly for high-volume multimodal workloads
