From an output to the next decision

How AI Handoff connects the toolkit.

Work through a tool, review its results, then open AI Handoff in the final step. Your inputs, selections and calculated outputs travel together, so an assistant receives the actual session rather than a screenshot to interpret.

Choose a task-specific prompt, agent instructions, exact JSON, Markdown or MCP-shaped context. Review and export locally, or explicitly choose the optional AI drafting connection.

Practical decision support. These tools use transparent local rules and calculations. They do not secretly call an AI model, scan an application or manufacture research evidence. You can export a brief for your own assistant.
