What we excluded (and why)

• Beautiful.ai / Pitch as primary picks: still available, but lower 2026 mindshare than Gamma, Canva, and PPTX-native generators for new AI slide projects.
• Treating HTML export tools as pixel-identical to PowerPoint without opening the file locally.

What “PowerPoint (PPTX) delivery” means here

• End state: a .pptx opened in Microsoft PowerPoint (or compatible apps).
• Out of scope: animation authoring guides; Keynote-only unless exporting PPTX.

At a glance

Incumbents

Microsoft Copilot in PowerPoint

• Drafts and reshapes slides inside PowerPoint for Copilot-licensed tenants.
• Limitations: Not a headless deck API for arbitrary CI without additional automation.

Google Slides + Gemini

• Many teams author in Slides with Gemini assistance, then File → Download → Microsoft PowerPoint (.pptx) for external stakeholders.
• Limitations: Not the same as native PowerPoint chart objects; test charts after download.

Creator and AI-native tools

Gamma and Canva

• Gamma: web-native; PPTX export available—expect possible font/spacing shifts when moving to desktop PowerPoint (common with HTML-first tools).
• Canva: strong brand kits; some effects do not translate cleanly to PPTX.

Presentations.AI

• Positions around editable .pptx and API-scale generation (presentations.ai).
• Limitations: Validate data-heavy charts in PowerPoint once.

PPTX-oriented vendors (ChatSlide, PowerPresent, Dekked)

• Market document-grounded or native PPTX generation (ChatSlide, PowerPresent, Dekked).
• Limitations: Smaller vendors; always open the .pptx in desktop PowerPoint before trusting marketing copy—do not rely on a single third-party comparison post.

Manus and Lovart

• Manus: slide output within agent workflows (manus.im).
• Lovart: design-agent campaigns that may include slide-like deliverables (lovart.ai).
• Limitations: General agents—not slide DSLs; brand compliance is manual.

K2F

• What it is: .K2F → compile lock → k2f export-pptx (exporting PowerPoint).
• PPTX facts (v0.3): PPTX is a drawing of the lock; slight text reflow in PowerPoint is expected and allowed—not pixel-identical to PDF. Shapes/text are editable; this is not a full PowerPoint animation/chart object model.
• Boundaries: PPTX_IS_NOT_A_SOURCE. For pixel-identical pages, export PDF from the same lock.
• Agent fit: Pair Codex/Cursor/Claude Code with K2F skill; use Gallery templates.

Choosing a path

• Native PowerPoint editing → Copilot in PPT or a PPTX-verified AI generator.
• Google organization → Slides + Gemini → download PPTX.
• Agent verify + multi-format → K2F lock → PPTX (+ PDF/IDML/DOCX as needed).
• Board deck from PDF → document-grounded PPTX tool or Manus with QA.

Bottom line

Pick web-beautiful or PowerPoint-editable on purpose. K2F shares one lock across exports but honors Office reflow rules on PPTX—unlike PDF.
