AI document assistant that drafts PRDs, help docs and wikis from a short brief
Describe a problem and a feature, and get a structured first draft you can adapt to your team's PRD template.
Highlight a section and let AI expand, restructure or refine it, with tools like PRD Review that surface gaps before you ship.
Turn a short text prompt into flowcharts, sequence diagrams, Gantt charts and other professional diagrams.
Work in the same document simultaneously, follow edit history, and organize complex documentation in flexible hierarchies.

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.
