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.
Second-by-second activity tracking for billing and productivity
Records time spent in websites, individual files, apps and away-from-keyboard periods, then consolidates it to the second without a manual timer.
Associate tracked time with clients or projects out of the box, then filter and export it to generate invoices and reports.
Navigate your recorded activity down to the smallest detail to justify and corroborate what you bill.
All tracked data is stored on and stays on your own PC, with nothing uploaded, transmitted or stored online.
