Comparison
OpenCharts vs Miro
online whiteboard and collaboration platform
Miro owns the freeform whiteboard. OpenCharts pairs that canvas with structured diagrams, AI extraction, and slide decks so brainstorms turn into shippable artifacts.
By OpenCharts TeamPublished
OpenCharts is a free, AI-native alternative to Miro that combines an infinite whiteboard with structured AI flowcharts, rich notes, and AI-built presentations in a single workspace. Both tools excel at real-time visual collaboration, but OpenCharts adds one-click whiteboard-to-flowchart conversion, document-to-diagram AI extraction, and an MCP server for AI agents — all on the free plan with unlimited collaborators.

How they compare
OpenCharts and Miro solve overlapping problems differently. The matrix below makes the trade-offs concrete, and the migration note covers what it takes to switch when you're ready.
When to choose
The right pick for your team
Choose OpenCharts when…
- You want AI to turn a PDF, prompt, or whiteboard sketch into a structured flowchart automatically.
- You need both freehand whiteboard and structured flowcharts/notes/slides in one tool.
- Your team is cost-sensitive and you want unlimited free collaborators.
- You want to drive the canvas from AI agents (Warp, Claude Desktop, Cursor) via MCP.
- You'd like notes and slide decks without context-switching between separate apps.
Choose Miro when…
- You depend on Miro's huge ecosystem of marketplace apps and integrations.
- Your team is already standardized on Miro and your facilitation playbooks live there.
- You need Miro's specific facilitation features like timer-driven workshops and voting at the scale of a 200-person workshop.
- You require Miro's enterprise SSO/IT controls already approved by your security org.

Pricing and migration
What it costs, what it takes
Pricing
Pricing snapshot
OpenCharts is free forever; paid tiers raise AI credit limits and add team management. Miro's free plan caps editable boards at 3 and limits collaborators per board; paid tiers start around $8/user/month and gate advanced apps and admin controls.
Migration
Migrating from Miro
Export your Miro board as a PDF or image, drop it into OpenCharts, and Theo rebuilds the structure as native nodes and edges. For sticky-note brainstorms, paste the text into a Notes project — Theo will organize it into a structured outline or flowchart on demand.
Questions
Frequently asked questions
Is OpenCharts a free Miro alternative?
Yes. OpenCharts ships an infinite whiteboard, structured flowcharts, notes, and AI presentations on a free plan with unlimited real-time collaborators and no credit card required. Miro's free plan limits editable boards and collaborators.
Can I import my Miro boards?
Yes. Export your Miro board as PDF or PNG, drop the file into OpenCharts, and Theo extracts the structure into editable nodes and edges. For text-heavy brainstorms, you can paste the content directly into a Notes project and ask Theo to convert it into a flowchart or whiteboard.
Does OpenCharts have facilitation features like timers and voting?
OpenCharts focuses on AI-native creation: flowcharts, whiteboards, notes, and presentations. It supports threaded comments, presence, and shared cursors but does not yet include Miro's full facilitation suite (timers, voting widgets, breakout rooms).
Can multiple people draw on the same whiteboard at once?
Yes. The whiteboard supports real-time multiplayer editing with live cursors, presence indicators, and node locking. Multiple users can draw, add shapes, embed images, and annotate the same board simultaneously.
How does the AI flowchart generator compare to Miro AI?
OpenCharts AI extracts complete editable flowcharts from PDFs, PowerPoint, images, or text prompts in 5–15 seconds, including swimlanes, decision branches, and BPMN-style processes. Miro AI primarily helps generate sticky-note clusters and summarize boards rather than producing structured diagrams.
Can I drive OpenCharts from Claude Desktop or Cursor?
Yes. The public OpenCharts MCP server exposes 19 tools (project CRUD, AI extraction, Theo chat, research) that any MCP-compatible client like Warp, Claude Desktop, Cursor, VS Code, or Windsurf can call with a bearer token.
