AI notetaker that records, transcribes and summarizes meetings — bot-free
Capture meetings with a visible notetaker or completely bot-free, so you can record your way and keep participants comfortable.
Get accurate transcripts, concise summaries and extracted to-dos delivered right after each call.
Search and ask questions across your entire meeting history to surface decisions, commitments and patterns.
Notes, insights and follow-ups flow automatically into Slack, Salesforce, HubSpot, Notion, Asana and other tools.

The open-source diagramming studio for builders
Paste a public GitHub repository and OpenFlowKit reads its files in the browser to draw modules and connections, with every arrow cited to the source line it came from.
29 diagram tools for Claude Code, Codex, Cursor, VS Code, Windsurf or any MCP client, so an agent can draw on the diagram you have open, one undo away.
Write or paste Mermaid, D2 or Structurizr; the text and the canvas remain the same diagram, so you can round-trip between syntax and visuals.
Move from system context to containers to components in linked views that all stay grounded in a single architecture model.
