How it works

From idea to diagram in seconds

OpenCharts combines the power of AI with an intuitive canvas to help you create professional diagrams faster than ever before.

1

Describe what you need

Simply type what you want to create in natural language. Whether it’s ‘a user authentication flow’ or ‘an e-commerce checkout process’, our AI understands your intent.

AI generates your diagram

Watch as AI creates nodes, connections, and layouts automatically. It understands context, creates logical flows, and applies professional styling.

Why OpenCharts

Why pay for three tools when one does it all?

OpenCharts bundles flowcharts, whiteboards, notes, presentations, file storage, and AI into one platform at a fraction of the price.

One tool, not three

Everything your team needs, bundled

Flowcharts, whiteboards, notes, presentations, file storage, and team chat in a single workspace. Competitors make you buy Miro + Notion + Google Slides separately. We ship it all.

AI-native, not AI-bolted

Built into every canvas from day one

Other platforms charge extra for AI add-ons. OpenCharts includes AI generation on every plan, even Free. Upload a PDF, describe what you need, and watch it build in seconds.

3–5× cheaper

More for less, no per-seat surprises

Miro is $8/user/mo for whiteboards alone. Lucidchart is $7.95+/user/mo for diagrams only. OpenCharts Unlimited is $24.99/mo total for everything, including 1M AI credits.

Enterprise-ready now

Security isn't locked behind 'Contact Sales'

SSO/SAML, 2FA, row-level permissions, encryption at rest & in transit, version history, data residency, and 99.99% uptime SLA. Available from launch, not hidden in an enterprise upsell.

The math is simple
