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.

AI scientific figure generator for publication-ready illustrations, charts and flowcharts
Three dedicated engines: Illustration, DataChart and FlowChart for scientific images, data plots and protocol diagrams respectively
Six illustration input modes: text, sketch, photo, PDF, reference figure and photo enhancement, backed by hundreds of discipline-specific templates
Data charts straight from CSV or Excel across around 50 chart types, including volcano plots, survival curves, forest plots and heatmaps
Fully editable output: change any label, recolor, redraw a region or shift a box and its arrows without regenerating the figure

#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-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

Editable scientific figures and graphical abstracts from a prompt
