Miro is a team whiteboard. Overscope listens, just to you.
Miro is an expansive online whiteboard built for teams to brainstorm, diagram, and plan together across an effectively infinite canvas. It's collaboration-first and feature-broad. Overscope is the opposite shape: a single-person, voice-first tool for catching and structuring your own thinking on iPhone.
What Miro is great at
Miro excels at real-time team collaboration on a huge shared canvas, with a deep library of templates and diagram types for group work.
Where Overscope is different
Overscope isn't a collaboration tool — it's for your own ideas, captured by voice. You hold to talk, the app transcribes on-device, and your spoken thinking becomes a structured map. No accounts to invite, no board to manage, just speak and see the shape.
| Overscope | Miro | |
|---|---|---|
| How you build the map | Speak — it structures for you | By hand, node by node |
| Primary input | Voice, push-to-talk | Typing, tapping, dragging |
| On-device transcription | Yes (Apple Speech) | Not the focus |
| Platform | iPhone, iOS 26 | Varies |
A characterization of each app's approach, not a feature audit. Miro is a capable mind-mapping tool; Overscope's difference is voice-first capture.
- Voice-first solo capture: hold the button, speak, and the structure forms — no manual board setup.
- On-device transcription that's processed in memory and discarded; audio is never saved or uploaded.
- Six focused mind-map layouts rather than a sprawling general-purpose canvas.
- Native iOS 26 app with Liquid Glass — fast to open and capture the moment an idea lands.
The verdict
For team workshops on a shared infinite canvas, Miro is built for that. For getting your own ideas out of your head by talking, Overscope is the more direct path.
