Decky vs HummingDeck

Decky is a presentation system that learns from existing decks, brand assets, imagery, and approved content to generate on-brand presentations. Users can import PowerPoint or Google Slides files, scan a website, and upload logos, images, icons, and other materials. Brand rules apply at the object level, covering fonts, colors, logo use, and locked layout elements. Decky creates native.pptx files and Google Slides decks without a proprietary format or conversion step. Slides can be revised through chat or edited normally in PowerPoint and Google Slides. A REST API and MCP server expose templates, slide libraries, and generation actions to AI assistants and internal agents. Enterprise governance includes centralized templates, approved slide libraries, role-based permissions, SAML 2.0 SSO, version control, and usage visibility. Decky states that it is SOC 2 Type II certified, encrypts data in transit and at rest, and does not use customer content to train its models or third-party foundation models. Deleted data is removed from active systems and backups within 30 days. The Free plan costs nothing. Pro costs $29 a month. Enterprise is a custom annual plan.
