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-first email that turns your inbox into a chat-like workspace
AI snapshots unread mail and long conversations so you can catch up in seconds, while priority inbox surfaces the messages that matter first.
Draft quick replies, contextual responses, and brainstormed messages with AI assistance directly inside the composer.
Threads are grouped by person like a messenger app, and every connected account lands in one inbox with file management and powerful search.
Shared inboxes, channels and groups, collaborative docs and notes, tasks, and one-click audio and video meetings all live inside your mail workspace.
Free / Open-sourceFunctions primarily as a lightweight CLI runtime for local models rather than a full-featured chat interface.
