How OpenCharts compares
One workspace instead of three subscriptions. AI built into every canvas, not sold as a separate add-on. See the full feature and pricing breakdown below.
The TL;DR
Three reasons teams switch — bundled, AI-native, fairly priced.
All-in-one
Flowcharts, whiteboards, notes, presentations, code canvas, image canvas, file storage, team chat, and a community forum — one workspace, one login.
AI-native, not bolted on
AI generation is built into every canvas from day one — included on every plan, even free. No bolt-on add-ons or separate subscriptions.
3–5× cheaper
Miro + Notion + Google Slides costs $25+/user/mo across three subscriptions. OpenCharts Unlimited gives you everything for $24.99/mo total.

Why teams switch
Honest takes on each tool — including when you should not switch.
OpenCharts vs. Miro
Miro is great at infinite-canvas brainstorming. Where it falls short is structured output: real flowcharts, polished slide decks, and AI generation that actually understands a process.
- AI diagram generation is included on every OpenCharts plan; Miro AI is a paid add-on with credit caps.
- Native presentation builder with theme-aware slides, instead of stitching frames together.
- Document → flowchart extraction: drop in a PDF or PPTX and get an editable diagram in seconds.
- Built-in team chat, file storage, and a community forum — Miro requires Slack + Drive + Discourse.
- $24.99/mo flat for unlimited canvases and collaborators vs. Miro's per-seat Business pricing with feature gates.
When to stay with Miro: Pick Miro if you only need a freehand whiteboard and your team already lives there. Pick OpenCharts if you want diagrams, notes, slides, code, and image work in one workspace.
OpenCharts vs. Lucidchart
Lucidchart is a strong dedicated diagram editor. It's also exclusively a diagram editor — and AI is bolted on as a separate Lucid AI subscription.
- Same caliber flowchart editor (20+ node types, auto-layout) plus whiteboards, notes, slides, code, and image canvas in one app.
- AI prompt-to-diagram and PDF/PPTX-to-diagram are native and free; Lucid AI is a paid add-on.
- Real-time multiplayer with live cursors, threaded comments, and version history on the free plan.
- Community forum with template fork/remix — Lucidchart's gallery is read-only.
- Diagram → AI coding prompt for engineering teams. Hand off a system diagram and get scaffolded code.
When to stay with Lucidchart: Pick Lucidchart if your enterprise has standardized on Lucid Suite and you don't need anything beyond diagrams. Pick OpenCharts if you also need notes, slides, code, or AI built into the canvas.
OpenCharts vs. Notion
Notion is a beautiful docs + databases tool. It is not a diagramming tool, a whiteboard, a slide builder, or a code canvas — even though teams keep trying to use it as all four.
- Real flowcharts, whiteboards, presentations, and code canvases — Notion's "diagrams" are mermaid code blocks and embeds.
- Notes that sit next to your diagrams and slides instead of in a separate tool.
- AI generation included on free; Notion AI is $10/user/mo on top of the seat cost.
- Multi-step automation builder (E.V.I.) with a visual workflow editor — Notion's automations are limited to database actions.
- Real multiplayer cursors on every canvas; Notion's "presence" is page-level only.
When to stay with Notion: Pick Notion if you mostly write long-form docs and run lightweight project tracking. Pick OpenCharts if you do real visual work — diagrams, slides, sketches, image briefs, code prototypes — alongside your docs.

Frequently asked questions
Can I import my Miro or Lucidchart boards into OpenCharts?
Yes — export your Miro or Lucid board as a PDF or image, drop it into OpenCharts, and Theo will rebuild it as an editable flowchart or whiteboard. You keep the structure but gain AI editing, presentations, and the rest of the workspace on top.
Is the OpenCharts free plan really better than Miro / Lucid / Notion free?
Yes. The OpenCharts free plan includes AI generation, every canvas type (flowcharts, whiteboards, notes, presentations, code, image), unlimited collaborators on shared projects, threaded comments, and version history. Miro caps free boards, Lucid caps shapes per document, and Notion AI is a paid add-on.
What's the AI cost compared to Miro AI / Lucid AI / Notion AI?
OpenCharts AI credits are bundled into every paid plan and even the free plan ships with monthly AI credits. Miro AI, Lucid AI, and Notion AI are sold as separate per-seat add-ons (typically $8–$10/user/mo on top of the base seat).
What about enterprise features like SSO, audit logs, and SLA?
OpenCharts Enterprise includes SSO/SAML, RBAC, row-level security, AES-256 encryption at rest, immutable audit logs, 99.99% SLA, optional data residency, and dedicated support — comparable to Miro Enterprise and Lucid Enterprise but priced for the all-in-one workspace.
If I'm using all three (Miro + Notion + Slides), what does migration look like?
Most teams migrate canvas-by-canvas. Start by importing your most-used Miro boards or Notion docs, recreate top-of-mind slide decks with the AI presentation builder, and keep the legacy tools running until your team is comfortable. We've seen a typical migration take 2–4 weeks for a 50-person org.
