Gamma vs OpenCharts

Gamma is a visual communication platform for creating presentations, documents, websites, social media, and graphics with an AI agent. Users can begin with a prompt, outline, or file, then refine the result with AI or manual editing. For presentations, Gamma offers text-to-presentation creation, smart layouts, templates, custom themes, and AI-generated visuals. It imports PDF and PowerPoint files and exports to PDF, PowerPoint, PNG, and Google Slides. Projects are private by default and can be shared with selected people, a team, or publicly, with real-time collaboration. Teams can use shared workspaces, templates, brand controls, and custom instructions; Enterprise lists SSO, SCIM, permissions, and admin controls. Gamma has a mobile app but no desktop app. Its free plan costs nothing and allows up to 10 slides per prompt, with PDF and PPTX import and several export formats. Pro lists up to 10 custom domains and Ultra up to 100. Gamma says Business and Enterprise workspace content is excluded from AI training, while individual workspace users can opt out in account settings.

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.
