Time blocking for macOS that plans around your calendar
Drag tasks from your list onto the timeline or apply recurring templates to fill your day with focused blocks.
Events sync both ways with Apple, Google and Outlook calendars so your plan and your real calendar stay aligned.
Work the same plan as a day timeline, a week grid or a month view, and export to PDF or CSV when you need a copy.
Treat lists as projects with an overview, deadline and finish line, and split large tasks into scheduled sessions.
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.
