Open WebUI is an open-source, self-hosted AI interface that lets individuals and organizations run any model — local or cloud — inside a workspace they fully control. It ships as a one-command install, supports Ollama, OpenAI-compatible and Anthropic endpoints, and extends through Python tools, functions and pipelines.
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.

Open WebUI is an open-source, self-hosted AI interface that lets individuals and organizations run any model — local or cloud — inside a workspace they fully control. It ships as a one-command install, supports Ollama, OpenAI-compatible and Anthropic endpoints, and extends through Python tools, functions and pipelines.
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
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.
Pull structured data out of PDFs, scans and invoices via REST endpoints, or let AI invoice parsing return standardised JSON without any template.
Convert PDFs to Excel, CSV, XML, JSON, HTML and images, and run OCR on scanned documents to make them searchable and machine-readable.
Merge, split, fill forms, add watermarks, barcodes and stamps, and generate new PDFs programmatically from HTML or templates.
Official connectors for Zapier and Make expose the same API to no-code users, so document workflows can be automated without server-side code.

免費 / 開源Focuses on collaborative team AI workspaces and plugins, but shares similar open-source architectural goals.
專項更強強烈專注於重視隱私的文件聊天與本地 RAG 管道,但提供較少的通用聊天 UI 功能。
PDF.ai lets you chat with any PDF using AI: upload or open a document and ask questions to get answers with citations, instant summaries and extracted data. The platform also provides a developer API for parsing documents, pulling out structured data and splitting PDFs inside your own workflows.
