The AI product manager for your entire team
Turn a sentence, transcript, or notes into a real PRD grounded in your Notion, Linear, GitHub, and Granola context.
A CPO-level review scores each document on strategy, structure, clarity, and completeness, then offers line-level edits you can accept in one click.
Build a clickable prototype straight from a spec, refine elements by pointing, and share a link the same day—or open in v0, Lovable, Bolt, or Cursor.
Pull context from docs, tickets, code, and meetings, then push finished work to Google Docs, Notion, Confluence, Linear, Jira, Slack, and Teams.

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.
