In their own words
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.
STORYD
STORYD creates business presentations with artificial intelligence and storytelling templates through web and API access. Users describe a topic, select a communication structure, and the service says it can produce a deck in 60 seconds. Writing tools can rephrase, brainstorm, shorten, lengthen, or change storytelling approaches. People can collaborate in real time and add text, lists, images, charts, and numbers. Branding controls include uploading a deck to extract its organizational theme and font, setting branding options, and choosing from hundreds of layouts. Exports listed on the pricing page include PowerPoint, Google Slides, Keynote, and Canva; the integrations page describes PPTX downloads and marks Google Slides integration as coming soon. The Automate plan includes API access for presentation automation. The Free plan costs nothing when billed annually and includes 5 credits. Pro costs $18 a month billed annually, with unlimited credits, priority access, team collaboration, and real-time editing. Automate costs $100 a month billed annually, with unlimited users and 50 presentation credits per month.
