## StreamDocs.ai (PDF.co)

StreamDocs.ai now resolves to PDF.co, a low-code REST API from Artifex Software that automates PDF extraction, conversion, editing, generation and AI-powered invoice parsing across 3,000+ integrations.

**Preços e planos:** Freemium with a free trial (3,000 credits for one month, no credit card required), then monthly plans: Basic $8.99/mo (16,500 credits), Personal $22.49/mo (37,000 credits), Business 1 $44.99/mo (80,500 credits), Business 2 $89.99/mo (159,850 credits), Business 3 $270/mo (483,000 credits), and custom Enterprise pricing above 500,000 credits. Annual billing saves about 10%.

- **PDF extraction and parsing:** Pull structured data out of PDFs, scans and invoices via REST endpoints, or let AI invoice parsing return standardised JSON without any template.
- **Conversion and OCR:** Convert PDFs to Excel, CSV, XML, JSON, HTML and images, and run OCR on scanned documents to make them searchable and machine-readable.
- **Editing and management:** Merge, split, fill forms, add watermarks, barcodes and stamps, and generate new PDFs programmatically from HTML or templates.
- **3,000+ low-code integrations:** Official connectors for Zapier and Make expose the same API to no-code users, so document workflows can be automated without server-side code.
- **AI document classifier:** Automatically sort and organise incoming PDFs with custom classification rules, streamlining document management at scale.

**Pontos fortes:** Mature, widely used API backed by Artifex and the PyMuPDF team; Broad endpoint coverage, from conversion and OCR to AI invoice parsing; Official no-code connectors for Zapier and Make; Generous free trial with 3,000 credits and no credit card

**Limitações:** Credits are consumed per page or call, so heavy volumes need larger plans; The streamdocs.ai brand is gone, so older bookmarks redirect unexpectedly; Toolkit is broad but each task still needs API plumbing or a no-code recipe
