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, monitor triggers, or manually, with external connectors, human approval gates, and generated deliverables. Connectors include Stripe, HubSpot, Slack, Google Sheets, Discord, Airtable, Gmail, Notion, GitHub, and others. The REST API can create and manage multiple project types, and Theo MCP provides 113 tools and a hosted endpoint. Accounts include 10 GB of Drive storage at no cost. Free Forever includes 500K AI credits and one of each project type. Starter costs $9.99 per month, Pro costs $24.99 per month, and Teams costs $14.99 per month with a three-user minimum. OpenCharts states that customer data is not used to train or fine-tune AI models.
