What is a PowerPoint alternative for businesses?
Nexoria Slides edits presentations in PPTX format on a LibreOffice basis. You test the switch with your existing slide decks: do templates, fonts and slide masters fit, is media displayed correctly and does exchange with PowerPoint users work?
In addition, presentations can be created from shared documents in the Nex AI chat. A generated draft needs a review of its content and design. Check the draft against the requirements of your presentation.

What matters when switching from PowerPoint
Templates and slide masters
Choose a copy of your company template and a representative slide deck. Check title slides, content layouts, placeholders, tables and footers. Add a new slide, change a layout and check whether the design matches your template. Compare fonts, line breaks and positions with your previous output.
Media, transitions and animations
Test the complete presentation in its intended sequence. This includes embedded and linked media, transitions, animation sequences and the display on the intended screen. If your presentation depends on a specific sequence of effects, successfully testing it is a prerequisite for the switch.
Macros and add-ins
PPTM files with macros must be considered separately. Office macros require their own testing on the LibreOffice basis and may need adjustments. Test how your macro code runs and the add-in workflows you need. Clarify adjustments or replacements before the switch.
Save and return PPTX files
Save the edited test copy and open it again in PowerPoint. Check the same layouts, media and workflows. Compare rendering and features against your agreed acceptance criteria. Keep the unchanged original file.
AI-generated slide decks in the Nex AI chat
Nex can create a draft presentation from shared documents. Define the target audience, occasion and relevant content in advance. Then check every statement against the source material, especially figures, names, time references and conclusions. Revise the structure and design for your actual presentation.
Creating a presentation and editing existing PPTX files are different tasks. Test both with your own material if you need both. Include your team's additional requirements in the joint slide deck test.
Files and AI processing
According to the operator, documents are stored in Germany. For AI answers, relevant content may be transmitted to the Mistral AI API. Technical error monitoring runs via Sentry, based in the USA, without access to document content. For the optional VoiceBot, Telnyx (headquarters USA, EU branch Ireland) provides the telephone connection. Check the data flows under Security and privacy for the features you need.
ChatGPT, Claude, Gemini and Langdock can optionally be connected via your own provider account and a Nexoria MCP after admin approval. The terms, data flows and settings of the respective provider must be taken into account.
Slides as part of the Nexoria platform
Drive, document search and Nex combine file storage, search and work with shared documents. Nexoria Office adds Doc, Calc and Slides. The wider platform scope includes Workspaces, OCR and transcription, tasks, automations and chatbots. Mail, Meet and VoiceBot are optional add-ons.
SharePoint, OneDrive and Google Drive can be connected as knowledge sources on request. We set up the integration depending on your environment and permissions. On request, we also look into connecting other storage, CRM, ERP and in-house systems.
