Log your thoughts and watch your mind calm down

A thought arrives in the shower, in the car, mid-argument, and by the time you could write it down it's gone. Say it out loud instead. Corteks files it, reads it, and shows you what you keep circling.

The honest version

Replicate your mind. This is not just another notes app.

Every notes app makes you decide where a thought goes before it will save it. You pay that tax when you have the least patience for it, so the app stays closed and the thought stays lost.

Corteks removes the decision. You never organise anything. Think of it as a second brain for spoken thoughts: one that reads back what it noticed instead of asking you to tag it.

One input is all it takes

Capture takes about four seconds. The rest runs without you.

You dump it

Speak it, type it, or drop in a screenshot. One button, no fields. Dictation runs on your phone, so the audio never leaves it.

It gets read

It gets a title, a summary, a kind and tags, then it's checked against everything you've said before.

It joins the rest

It lands on your graph, wired to the thoughts it shares themes with. Clusters form on their own, closer to an AI mind map of your thoughts than a list.

Every thought is one of four kinds

Not what it's about, what it's doing.

Ideas

Something to make, try, or do.

Reflections

Something you noticed about yourself.

Feelings

The state you were in, on the record.

Wondering

An open question you haven't answered.

Ask your mind

Explore your mind

Answers come from your own thoughts and nowhere else. If you never said it, Corteks won't claim or assume that you did.

What have I been avoiding?

Three things keep coming back without moving forward:

Focusing on your health and building a solid fitness routine. Mentioned six times since April, always as “starting Monday”.

You've contemplated switching careers four times now, and never once written down an answer.

You've mentioned your relationship with your dad several times. It might be time to actually do something about it.

Questions

The honest answers

What is Corteks?

Corteks is an app for capturing raw thoughts, the ones that arrive in the shower or mid-conversation, by voice, text, or screenshot.

How does Corteks work?

You capture in about four seconds. The AI titles it, tags it, checks it against your history for patterns, and adds it to your mind graph.

Is Corteks a note-taking app?

Not really. A notes app makes you file things yourself. Corteks is closer to a voice brain dump app: you never choose a folder or a tag.

What happens to my thoughts?

Speech is turned into text by your phone’s own dictation, and we never receive the audio. The text is sent to Anthropic to produce the analysis and weekly reading. Corteks isn’t end-to-end encrypted, a disclosed design choice, and there’s no advertising or tracking. Delete anytime. See the full privacy policy for details.

What does Corteks cost?

Corteks Pro is $9.99 a month or $79.99 a year. Every new account starts with a free trial, and nothing is charged when you sign up. See the pricing beside these answers.

Can I cancel?

Yes, any time, from your Apple ID subscription settings. Cancelling stops the renewal; everything you have already captured stays readable and exportable.

What happens when the trial ends?

Capture pauses until you subscribe. Nothing is deleted and nothing is locked away: every thought you have already captured stays readable, searchable and exportable, for free, forever.

When is Corteks available, and on which platforms?

On the App Store now, for iPhone running iOS 15.1 or later. Android is deferred, with no timeline yet.
