OpenCharts
What it is
OpenCharts is an AI workspace for creating and managing flowcharts, presentations, notes, code, video, and agents. Its Theo AI turns plain-language descriptions into these project types, including flowcharts on an infinite canvas with terminal, process, decision, and data nodes. The presentation editor includes editable slides, speaker notes, transitions, rehearsal coaching, web publishing, and PPTX export. Theo Agents can start from schedules, webhooks, monitor triggers, or manual requests, and support external connectors, human approval gates, and generated deliverables. The REST API manages flowcharts, whiteboards, notes, presentations, sheets, boards, personas, and agents. OpenCharts lists web, Windows, macOS, and Chrome extension support; its desktop app offers two-way Drive sync on macOS 13 or later and Windows 10 or later. Accounts receive 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 says it does not use customer data to train or fine-tune AI models.
