Deckary

Quick answer

Deckary — Turn plain English prompts into Excel formulas, charts, and slides. It's paid. Best for building financial models faster by prompting the AI to construct complex formulas and structured tables.

Deckary is a paid AI-powered Excel add-in that acts as an agentic assistant living directly inside your open workbook, letting you build formulas, pivot tables, and charts using plain-language prompts. Rather than switching between tools or copying data into a separate chat interface, Deckary works where analysts, finance teams, and consultants already spend their day: inside Microsoft Excel. The agent reads your actual workbook context and executes changes in real time, so you can describe what you want in plain English and watch it happen without writing a single function manually. What sets Deckary apart from generic AI chatbots is its deep integration with the Excel environment combined with a built-in PowerPoint generation feature, making it possible to go from raw data to a polished slide deck without ever leaving your spreadsheet workflow. It is purpose-built for power users who need speed and accuracy when handling financial models, data analysis, and client-ready presentations, making it especially valuable for management consultants, FP and A analysts, and operations teams who regularly produce reports from complex datasets.
