Deckary

Overview

Deckary is an AI-powered productivity add-in designed for Microsoft PowerPoint, Excel, and Word. It operates natively inside the Office ecosystem on both Windows and macOS, enabling consultants, financial analysts, and independent professionals to build and edit real, editable presentations, financial models, and documents without switching to separate AI tools. Unlike standalone presentation generators, Deckary preserves the fidelity of native Office formats, so every slide, object, and formula remains fully editable directly in PowerPoint, Excel, or Word.

At its core, Deckary provides a suite of agentic AI tools. The Agentic AI Slide Builder transforms plain-text business problems or attached CSV data into complete, structured slides featuring charts, bullet points, and icons. Users can also select existing slides and instruct the AI to rewrite, restructure, or reformat content while maintaining layout and branding. The AI Excel Agent scaffolds financial models, analyzes workbooks, and automates formula creation and formatting inside Excel. The AI Word Agent assists with drafting, rewriting, reviewing, leaving comments, and document formatting requirements. All AI output respects user-defined brand guidelines, ensuring that generated content matches fonts, colors, and templates from the start.

Beyond AI generation, Deckary includes consulting-grade productivity features. Users can create professional charts such as Waterfall, Mekko/Marimekko, Gantt, and stacked bar charts, all linked to Excel data for dynamic updates. A comprehensive Brand Control system performs deck-wide consistency checks and allows approved slides to be saved to a shared library. The add-in also offers over 2,000 icons that are auto-suggested based on slide content, along with country flags and AI-generated images, plus keyboard shortcuts for alignment, distribution, swapping, and resizing—standard tooling used by top-tier strategy firms. Deckary Canvas is an additional local-first workspace for building HTML decks with visual editing, validation, and export, designed for AI coding tools like Claude Code, Codex, and Cursor.

Deckary is engineered with enterprise-grade security and privacy: data is encrypted in transit via TLS and at rest using AES-256, access is session-based, and the service is GDPR-compliant, hosted in the Netherlands. Users retain full ownership of their data, which is deleted within 30 days of account removal, and payments are handled securely by Stripe. With a 14-day free trial and flexible monthly or annual plans, Deckary enables consultants and teams to drastically reduce the time spent on deck production, financial modeling, and document formatting, turning raw analysis into client-ready work in minutes.
