Layerz is a structured spreadsheet, ready for AI: your own Claude builds and edits the model through MCP, and the model keeps its logic, history and conventions between sessions. Each page below states dated, sourced facts about the other tool, and says plainly when the other tool is the right choice.
Claude on its own can draft a financial model in a chat, keep instructions and files in a Project, and create an .xlsx file with its built-in skills. Layerz is not an alternative to Claude: it is a structured spreadsheet that Claude connects to through MCP, so the model keeps named variables, a history and its conventions between sessions. Use Claude alone for a one-off draft; add Layerz when the same model is updated every month, by you or by several people.

Claude in Excel is Anthropic's add-in that reads and edits an open workbook, cites the cells it uses, and is included in paid Claude plans. Layerz is a structured spreadsheet that the same Claude drives through MCP: the model keeps named variables, a history and its conventions between sessions, and exports to Excel with live formulas. Use Claude in Excel to work on a workbook you received; use Layerz when the model has to survive the next edit, the next session and a reviewer, and many users do both.

Layerz is a spreadsheet: a structured one, built so an AI agent can edit it without breaking it. Excel stays the universal format and the right tool for one-off analysis, offline work, VBA and Power Query. Layerz keeps the model logic in named variables with a history, and exports a standard .xlsx with live formulas on every plan, so the client never needs Layerz.
