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.
Agentic social media scheduling for 30+ channels
Write a post once and publish to every selected channel, previewing the whole schedule visually before it goes out.
Claude, ChatGPT, Claude Code, Cursor, Grok, OpenClaw and others draft, schedule and analyze posts programmatically.
Invite teammates, assign posts, and keep every channel and approval organized in a shared workspace.
Set a milestone like 100 likes and Postiz automatically posts, likes, or comments to keep engagement going.
