Turn plain sentences into real Google Calendar events with AI
Describe an event in ordinary words and Magic Cal turns it into a real entry on Google Calendar, including the title and timing it can infer from your sentence.
A "Magic Event" option appears right in the Google Calendar create menu, so you never have to leave the page or open a separate chat window.
The listing explicitly supports input in any language, letting you phrase events the way you actually speak.
Interpretation of your sentence is handled by the gpt-3.5-turbo model, one of the well-known ChatGPT models.

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.
