In their own words
Microsoft PowerPoint
Microsoft PowerPoint helps users create, design and share presentations across web, desktop and mobile versions for Windows, macOS, Android and iOS. It offers thousands of customizable templates, and users can write or draw on slides and convert input into text or shapes. Presentations can be shared for real-time collaboration with comments and @mentions. Copilot can rewrite, reorganize or add slides, while Speaker Coach provides feedback on pace and vocabulary. Accessibility Assistant suggests adjustments to format, color and word choice; Cameo supports prerecorded video alongside slides. The free web tier includes basic tools, sharing, collaboration, dictation and 5 GB of storage. Microsoft 365 subscriptions bundle PowerPoint with apps including Word, Excel, Outlook, OneNote, OneDrive and Teams. Personal costs $9.99 a month with 1 TB storage; Family costs $12.99 a month with up to 6 TB. Fully installed Office apps can work offline, but after at least 31 days without internet they cannot edit or create documents. Subscriptions renew automatically unless canceled.
OpenCharts
OpenCharts is an AI workspace for flowcharts, presentations, notes, code, video, and agents. Theo AI can create these materials from plain-language descriptions. Flowcharts use terminal, process, decision, and data nodes on an infinite canvas, with automatic layout and export tools. The presentation editor supports editable slides, speaker notes, transitions, AI generation, rehearsal coaching, web publishing, and PPTX export. Theo Agents can start on schedules, webhooks, monitoring triggers, or manually; they can use external connectors, human approval gates, and produce deliverables. Connectors include Stripe, HubSpot, Slack, Google Sheets, Discord, Notion, GitHub, and others. A REST API manages project types, and the Theo MCP server provides 113 tools and five readable resources. Each account starts with 10 GB of Drive storage, including Free Forever. That plan costs nothing and includes 500K AI credits and one of each project type. Starter costs $9.99 a month, Pro $24.99 a month, and Teams $14.99 a month with a three-user minimum. OpenCharts says it does not use customer data to train or fine-tune AI models.
