How is Dekked different from other AI presentation tools?

Most AI presentation tools build slides as HTML web pages first, then convert to PPTX — which breaks layouts, corrupts fonts, and triggers repair dialogs. Dekked is a native PPTX generator: slides are built directly as PowerPoint objects, so exports work perfectly in Microsoft PowerPoint, Google Slides, and Keynote every time.

Can I convert a PDF to PowerPoint with AI?

Yes. Dekked is purpose-built for PDF-to-PowerPoint conversion. Upload any PDF and our AI extracts the text, tables, and figures, then generates a professional slide deck with real editable charts.

Can I upload my own company or university PowerPoint template?

Yes. Upload any .pptx template and our AI analyzes its colors, fonts, and slide master layouts, then generates slides that follow your template precisely. Available on Standard and Premium plans.

What does Dekked cost?

Dekked uses credit-based pricing. Presentations start at $1.99 (Pay As You Go), $9.99 for a 7-presentation credit pack, or $11.99/month for Standard with 10 presentations per month.

Does Dekked support charts and data visualization?

Yes. Dekked creates real, editable PowerPoint charts (bar, line, pie, doughnut), diagrams, stat callouts, timelines, dashboards, and comparison slides. All are native PowerPoint objects.

What languages can I generate presentations in?

Dekked generates presentations in English, Arabic (with full RTL support), Spanish, French, and German. Multi-language generation is available on Premium plans.

Is Dekked better than manually creating slides?

Dekked generates a complete, professionally designed presentation in about 90 seconds. Manual slide creation for the same quality typically takes hours.

AI Presentation Tools in 2026: Native PPTX vs. HTML Export

May 10, 2026 6 min read

The AI presentation market has exploded, but a dirty secret lurks beneath the surface: most tools generate broken PowerPoint files. The root cause is architectural — they build slides as HTML, then attempt to convert them.

Two Architectures, Two Outcomes

Every AI presentation tool falls into one of two camps based on how they produce .pptx output:

HTML-to-PPTX Pipeline

Generates web page first
Converts HTML to Office XML
Fonts, layouts, charts break
Triggers repair dialogs

Used by: Gamma, Tome (now shut down), most AI tools

Native PPTX Generation

Builds Office XML directly
Charts are native PowerPoint objects
Perfect font embedding
Zero repair dialogs

Used by: Dekked, Beautiful.ai, Microsoft Copilot

The Repair Dialog Problem

When PowerPoint encounters invalid XML in a .pptx file, it displays a repair dialog. This is the single most common complaint about AI-generated presentations. The root cause is always the same: the tool built HTML first, and the conversion produced malformed Office Open XML.
