Frontier VLMs for document extraction, structured JSON and OCR
NuExtract and NuExtract3 are vision-language models built specifically for structured information extraction and OCR, and benchmark ahead of generalist models of comparable size.
Turn PDFs, scans and mixed-format documents into typed JSON objects or clean Markdown that downstream systems can consume directly.
A dedicated encoder family for entity recognition, pre-trained on LLM-annotated data, useful for classification and tagging pipelines.
Start on the hosted platform, then deploy the same models inside your own infrastructure when data residency or compliance requires it.

Self-hosted AI workspace for local and cloud models
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.

#1SpecialistOpen-source workflow automation built for AI agents and technical teams
SpecialistA free, open-source personal AI agent that learns your projects and works across every messaging app.
#3
SpecialistOpen-source personal AI assistant that runs on your own machine and works from chat apps

SpecialistSpecializes in visual workflow building and RAG pipelines rather than serving purely as a chat interface.

Free / Open-sourceFocuses on collaborative team AI workspaces and plugins, but shares similar open-source architectural goals.
SpecialistFocuses heavily on privacy-first document chat and local RAG pipelines, but offers fewer general-purpose chat UI features.

Free / Open-sourceTurn any document into AI-ready context with agentic parsing and extraction


Free / Open-sourceOffers robust multi-provider support and advanced user permission management, but has a slightly different configuration setup.
Free / Open-sourceDelivers a desktop-native application for running local models offline easily, but lacks Open WebUI's server-centric multi-user features.
SpecialistOpen-source AI automation that unifies agents, flows and 770+ app integrations
