## 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

## categorAIze.io

categorAIze.io targets a common data mess: large batches of mixed text, links, images and documents that need consistent labels. Instead of training a bespoke classifier, you define a category list — hierarchical if you want subcategories several levels deep — and the platform uses LLM technology to assign each uploaded item based on its textual and visual content. If you do not know the taxonomy yet, you can skip it entirely and let the AI propose a hierarchy, then rearrange it and set how many categories each level may contain.

Categorization is multimodal and can rely on text alone, images alone or both. There is no pretraining step and no requirement to commit to a fixed label set, so new categories can be added later as items accumulate. Work happens either manually in the browser or programmatically: a REST API lets you create, read and delete items and categories, batches can be imported and exported, and the support team will build plugins for specific use cases on request.

Billing is split in two. AI usage is pay-as-you-go credit, topped up as needed and starting with a refundable $5 balance, and you set a maximum cost per categorization event — which effectively decides how much of each item's text or how many images the model may read. Storage is separate and optional, from a free tier that keeps items about 24 hours and requires export, up to recurring monthly plans and enterprise on-premises or dedicated-cloud deployments with fine-tuned prompts, self-hosted models, an SLA and no markup on the underlying token pricing.

**Pricing & Plans:** Freemium with pay-as-you-go AI credit plus optional storage subscriptions. Start with a refundable $5 credit and cap the cost per categorization event; model tiers are priced per 1,000 tokens (about $0.003 basic, $0.06 cutting-edge) and per image (about $0.006). Storage plans run from a free 24-hour tier (export required) through $9.95/month for 750 items and 1 GB, $49.95/month for 5,000 items and 10 GB, and $149.95/month for 20,000 items and 40 GB. Enterprise covers on-premises hosting, custom prompts, self-hosted models and an SLA.

- **Custom, hierarchical categories:** Define exactly the labels you need — two or two hundred — and arrange them in hierarchies several levels deep, with no dependency on a fixed vendor taxonomy.
- **AI-generated taxonomies:** If you do not know the categories yet, let the model propose a suitable hierarchy and cap how many categories may appear at each level as your data set grows.
- **Multimodal content support:** Categorize by text alone, image alone or a combination, covering plain text, URLs and documents as well as images in the same workflow.
- **API, GUI and batch access:** Drive everything from a browser interface, create and manage items through a REST API, or import and export batches of records, with custom plugins available on request.
- **Per-event cost control:** Set a maximum price per categorization event to bound how much content the model reads, keeping high-volume jobs predictable in cost.

**Strengths:** No pretraining and no fixed label set — new categories can appear as your data grows; Handles text, URLs, images and documents in one workflow rather than separate pipelines; Three access paths (GUI, REST API, batch import/export) suit both manual and automated work; Pay-as-you-go AI credit with a per-event cost cap keeps experimental spend bounded

**Limitations:** Storage beyond the free 24-hour tier is a separate monthly subscription, so costs stack; Some capabilities, such as bespoke plugins and enterprise features, require contacting the support team; The public site still promotes sign-up for beta access, which may mean onboarding is gated
