Our verdict on OpenCharts
OpenCharts is a browser-based workspace for creating AI-assisted presentations alongside flowcharts, notes, whiteboards, sheets, and other project types. It is aimed at solo makers, teams, and regulated-industry organizations that need to turn prompts or a website URL into editable presentation material. The builder can generate slide content, layouts, imagery, and brand themes, while users can refine slide elements, add charts and tables, and share live presentation links. Presentation creators are the clearest fit; diagram specialists may find the product’s emphasis less aligned with their primary workflow.
Pricing follows a freemium structure. Free Forever costs nothing and includes one presentation, 500K AI credits, 10 GB of Drive storage, all export formats, and no credit card requirement. Starter costs $9.99 per month for side projects and solo makers, with 1M AI credits, 25 GB of Drive storage, and PNG and JSON export. Pro costs $24.99 per month and adds 5M AI credits, unlimited projects, every export format, and API access. Teams costs $14.99 per user per month and includes real-time collaboration, team chat, an organization workspace, and an admin dashboard.
The strongest depth is around presenting rather than diagramming: presenter view includes speaker notes and a teleprompter, while the rehearsal coach provides pacing and filler-word feedback. Charts and tables can use Theo Sheet data, and integrations include Google Drive, Zapier, Slack, HubSpot, Stripe, Notion, Google Sheets, Discord, Airtable, Calendly, Gmail, Linear, GitHub, and Typeform. Web, Windows, macOS, and Chrome extension access broaden its working environment. Choose OpenCharts for AI-assisted decks, collaborative review, and flexible exports; choose a more diagram-centered tool when diagram creation is the main requirement.
