Summary

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 materials. Flowcharts use process, decision, data, and terminal nodes on an infinite canvas, with automatic layout and export tools. Presentation features include editable slides, speaker notes, transitions, rehearsal coaching, web publishing, and PPTX export. Theo Agents can start on schedules, webhooks, monitoring triggers, or manually, and can use connectors, approval gates, and generated deliverables. The listed connectors include services such as Stripe, Slack, Google Sheets, Notion, and GitHub. OpenCharts also offers a REST API for managing its project types and a Theo MCP server with tools and readable resources. Accounts begin with 10 GB of Drive storage, including the free tier. Paid plans are Starter at $9.99 per month, Pro at $24.99 per month, and Teams at $14.99 per month with a three-user minimum. OpenCharts says it encrypts data and does not use customer data to train AI models.
