The AI memory OS for your mind

SPEAK IT.
IT SORTS IT.
IT KNOWS YOU.

Not a note app — a second brain you talk to. Tap the mic and say anything. NeuroStack captures it, organizes it, tags it, and remembers it all — then learns you well enough to answer back.

What it does

Capture chaos.
Get back clarity.

Four ways NeuroStack turns the mess in your head into notes that file themselves.

Voice Notes

Speak it. Walk away. AI structures the chaos into notes you'll actually find later.

Photo OCR

Whiteboard. Receipt. Sticky note. Snap once — AI extracts every line, every action.

Lock-In

Pick 3 must-dos. Daily streak. Small wins compound into a different life.

Live Updates

Notes evolve with you. Voice or photo update any note, anytime.

The hard part, solved

Switch in one tap.

"I have too many notes to move." That's why people stay stuck in an app they've outgrown. Not here. Export from your old app, drop the file in, and NeuroStack imports and AI-organizes every note as it lands — Stacks, key points, checkable actions, smart tags. Bring thousands of notes over in one shot.

📥

Bring them from anywhere

Notion, Evernote, plain text, or a backup file. One import and your whole library comes across.

AI cleans them up

Don't just move your notes — NeuroStack organizes and tags every one as it arrives. No second step.

🧠

Into a brain that knows you

The moment they land they're searchable, tappable by tag, and folded into a memory that learns you.

How it works

Three taps to get started.

From a blank screen to fully organized in under a minute.

01

Sign in

One tap with Google, or a magic link by email. Done in 5 seconds — no setup.

02

Speak it. Snap it.

Talk it out or snap a photo. AI turns it into a clean, structured note instantly.

03

Come back to clarity

Your ideas are organized, searchable, and ready the moment you need them.

Your brain. Sorted.

Built to keep up
with you.

Everything works together — capture, organize, lock in, and protect. Your custom Stacks keep it all sorted automatically.

AI Organize & Tag

Every capture is filed into the right Stack with key points, checkable actions, and smart tags — automatically. Zero folders, zero filing.

It Knows You

NeuroStack learns who you are from everything you capture — your projects, people, and priorities — and surfaces what matters most.

Ask Your Brain

Ask a question in plain language. It answers from your own notes — with sources. Like texting your own memory.

Capture Anything

Voice, photos, web links, PDFs, even YouTube. Drop it in and it comes back a clean, structured note.

Daily Lock-In

Pick your 3 must-dos each morning, build a streak, and stay locked on what actually moves the needle.

Private & Secure

Encrypted and locked to your account. Your notes are never shared, sold, or used to train AI.

Everywhere you work

One brain, every screen.

Pull NeuroStack up in any browser — your work computer, your laptop at home — and see your live notes synced from your phone in real time. Capture on the go, review on the big screen. No app store, no transfers, nothing to set up.

Questions

Good questions.

Is my data secure?+
Yes. Your notes are encrypted in transit and at rest, tied to your private account. Only you can access them.
Where is my data stored?+
On secure cloud infrastructure (Supabase, US region) under your authenticated account — never shared or sold.
Does AI train on my notes?+
No. Your notes are never used to train any AI model. They're processed only to structure and serve your content back to you.
Can I export my notes?+
Anytime. Export as plain text, a clean PDF, or send straight to other apps via the native iOS share sheet.
Can I update an existing note with voice?+
Yes. Open any note, tap mic or camera, and speak or snap — AI weaves the update in with a timestamp.
What do beta testers get?+
Spots are limited and hand-picked. If you're selected, you use NeuroStack AIOS free for the lifetime of the app — when it goes public and pricing kicks in, founding testers never pay. Your feedback shapes what gets built.
