In their own words
Genspark AI Slides
Genspark AI Slides creates presentation decks from prompts or uploaded documents. It can analyze PDF, Word, Excel, and PowerPoint files, then research, organize, and design material into slides. The editing canvas sits beside chat: users can select elements, queue changes, check facts, add speaker notes, and present with a speaker console. Professional and Creative styles, Guide Mode, and Standard and Ultra quality modes provide different ways to shape generation. Standard uses 0.5× credits with the Genspark Gen-1 model; Ultra uses 1.0×. The service also offers more than 100 built-in Skills and can run code for calculations, data analysis, and charts. It supports brand controls and real-time collaboration, with exports to PDF, PPTX, or Google Slides; the help page says PDF and PPTX exports require a paid plan. A free plan costs nothing and includes 100 credits per day and 1 GB of AI Drive storage. Apps and access are listed for Android, iOS, macOS, Windows, web, and extension.
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.
