Voice mind mapping for iPhone — iOS 26

Speak your mind.
Watch it become a map.

Hold to talk. Overscope structures what you say into a live mind map — on-device, private, push-to-talk. Not a transcript, a map.

The blank-canvas problem

The idea was clear.
Then you tried to type it.

Thoughts arrive fast, branching, out of order. Notes apps make you flatten them into lines — and by the time it's tidy, the thought is gone. Overscope keeps the shape.

3×
Faster spoken than typed
You think out loud quicker than you can structure a note. Speak first; structure later.
Non-linear
How ideas actually arrive
Branches, tangents, second thoughts — not a tidy bulleted list.

Kept
Overscope turns what you said into a map, then discards the words. The map is the output.

STEP 02

Structure

Overscope extracts the structure — a root, its branches, their leaves. Concepts, not sentences. The map updates live as you speak.

“Launch plan”
Six pieces

Speak it. See it.
Shape it.

No chatbot, no copilot, no transcript. Overscope listens, structures, draws — then steps back.

FEATURE · 01

Voice to a live map

Hold the push-to-talk button and speak. The canvas builds itself as you talk — a root, branches, and leaves, structured from what you mean.

FEATURE · 02

On-device transcription

Speech is transcribed on your iPhone with Apple's Speech framework. Audio is processed in memory and discarded — it never leaves the device.

Apple Speech · audio never uploaded
FEATURE · 03

Six ways to see it

Switch any map between six layouts — radial, tree, org, cluster, outline, and bubble. The view that fits the thought, remembered per map.

radial · tree · org · cluster · outline · bubble
FEATURE · 04

Apple-native

Real Swift 6 + SwiftUI. Liquid Glass on iOS 26 — no web wrapper. Sign in with Apple, private cloud sync, ready for the upcoming Mac companion.

Edit and export

Tap any node to rename, add, or delete. Drag to rearrange. Then share the finished map as a PNG — into Notes, Messages, anywhere.

Private by design

No transcript artifact. No saved audio. No always-listening. Push-to-talk only — the mic is live solely while you hold the button.

Privacy

Audio never leaves
your iPhone.
Nothing is recorded.

Speech is transcribed on your device with Apple's Speech framework. The audio buffer is processed in memory and discarded — no file is saved, no audio is uploaded. The backend only ever receives the text it needs to extract structure, and only the generated map is logged. Never your raw speech, never a transcript.

What you say is yours.
We only keep the map.
On-device speech
Apple's Speech framework transcribes locally. Raw audio bytes never reach our servers or any third party.
No transcript artifact
You never see or export raw text. Transcribed words are intermediate state — the map is the only output.
Push-to-talk only
The mic is live solely while you hold the button. No always-listening, no hotword, no ambient capture.
Text-only backend
Structure extraction receives text, never audio. Only the map's metadata — timestamp, node count — is logged.

Speak.Structure.Shape.

Three verbs. One map. On your iPhone.

Honest scope

What it's not.

Five things Overscope refuses to be. The voice-app category is full of them. We picked a different shape.

Not this
✕A transcription tool
✕A voice recorder or memo
✕A chat assistant
✕Always-listening
✕Another notes app
This
→A map of what you meant, not a wall of words
→No audio saved — speech becomes structure, then it's gone
→One push-to-talk, one map. No back-and-forth.
→Push-to-talk only — you decide when it hears you
→Non-linear thinking, drawn as a mind map
Made for iPhone

The whole thing,
in your pocket.

iPhone is where a thought arrives — on a walk, in a queue, between meetings. So that's where Overscope lives. Hold, speak, map. Nothing to set up, nothing to sync first.

How it compares

Drawing apps draw.
Overscope listens.

Xmind and MindNode are beautiful — but you do the drawing. Notes is a wall of text. Overscope is voice-first: you speak, it structures the map. That's the wedge, not feature parity.

FAQ

Ten answers, in full.

One plan: Overscope Plus, $19.99/month or $149/year, with a 3-day free trial. There's no free tier — every map runs real on-device and cloud AI, so a perpetual free tier would lose money. No lifetime, no enterprise. Billing is through Apple In-App Purchase; cancel anytime.
Yes — privacy is the design, not a setting. Speech is transcribed on your iPhone with Apple's Speech framework; audio is processed in memory and discarded. The backend only ever receives the text it needs to extract structure, and only the generated map (timestamp, node count) is logged — never your raw speech or a transcript.
No. Overscope never saves an audio file and never produces a transcript artifact. Transcribed text is intermediate state you never see — the output is always a map, not a wall of words. If you want a transcription tool, this is a different product.
No. Push-to-talk only. The microphone is live solely while you press and hold the button. No always-listening, no hotword, no ambient capture — for privacy, intentionality, and battery.
Radial (hub), tree (left-to-right), org (top-down), cluster, outline (a collapsible indented list), and bubble (concept islands). Switch any map between them from the layout menu; your choice is remembered per map.
Yes. Tap any node to rename it, add a child, or delete it. Drag nodes to rearrange. The AI gives you a first draft of the structure; the map is yours to shape from there.
Yes — export any map as a PNG and share it into Notes, Messages, or anywhere. Other formats may follow in later updates; v1 ships PNG.
Overscope launches on iPhone (iOS 26) — speaking is phone-native, and the device is always with you. A Mac companion is planned after launch, sharing the same account so your maps follow you. It is deliberately not a v1 surface.
Transcription runs on your device (Apple Speech, on-device). Turning your words into a structured map runs on Overscope's backend, which receives text only — never audio, never a stored transcript. The provider processes the text under commercial terms and doesn't train on it.
Overscope is in development and not on the App Store yet. A TestFlight beta is the way in — the primary button flips to a live App Store link at launch.

Not a transcript, a map.
On the iPhone you already have.

Hold to speak. Overscope draws the map — on-device, private, push-to-talk. iOS 26. Plus is $19.99/mo or $149/yr, with a 3-day free trial.
