A graph-based second brain with mind maps, AI chat and cross-device sync
Save notes, ideas and web clips into a single library, then connect them in parent-child relations to grow a structured knowledge network.
Turn collected entries into mind maps so you can see how topics, projects and references relate at a glance.
Ask the built-in AI assistant questions about your own library, or capture and find information conversationally.
Use the all-in-one search bar and share target to capture ideas the moment they appear, without hunting for the right folder.

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.

MindMap AI is an AI mind map generator that starts from a prompt, PDF, video, audio file or webpage and returns a structured map you can edit by hand or refine in chat. Manual mind mapping is free forever, and AI credits are the paid layer.

Free / Open-sourceOffers robust multi-provider support and advanced user permission management, but has a slightly different configuration setup.

A studio for your mind: object-based notes that stay connected
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
