Corteks

Corteks is where you put a thought so you can stop holding it. Speak it, type it, or snap a photo. That is the whole job. Corteks reads what you captured, titles it, files it, and connects it to everything you have thought before. WHAT IT DOES WITH YOUR THINKING Reads every capture. A title, a one-line summary, what it is about, and the older thoughts it genuinely connects to. You never file anything yourself. Builds a graph, not a folder tree. Your thoughts cluster by what they are actually about, and you start seeing that you have been circling something for weeks. Writes your week, every Sunday. Not a step count. What you thought about, what changed, and what you keep returning to. Answers questions about your own mind. Chat is grounded in what you captured, so it points at your own words instead of inventing advice. Holds what you are working toward. Write down your objectives, focus three at a time, and Corteks reads those three closely. Three, because attention does not divide well. WHAT IT IS NOT No feed. No streaks. No badges. Nothing is public and nothing is shared, so there is nobody to perform for. It never tells you that you are behind. An objective that has gone quiet is reported as a fact, never as a failing. YOUR THOUGHTS ARE YOURS Everything is private to your account. It is used to build what the app shows you and nothing else: your graph, your readings, your weekly story, and the answers you get in chat. Export everything to your email whenever you like, in a readable file and as JSON. Delete your account and it all goes with it. CORTEKS PRO Start with a free trial. No card, and nothing is charged when you sign up. Pro covers capturing without limits, having every capture read and connected, your weekly reading, readings on your three focused objectives, and chat. After the trial, everything you already captured stays readable forever. Browsing, search, the graph, past readings and export never stop working. Corteks Pro is $9.99 per month or $79.99 per year. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel it any time in your Apple Account settings. Terms: https://corteks.app/terms Privacy: https://corteks.app/privacy-policy

This app works on audio you give it: files you import, videos you own. It cannot change the sound of other apps, it cannot push your device past its maximum output level, and it cannot affect phone calls. PRIVATE BY DESIGN All processing happens on your device using Apple's audio frameworks. There is no network code in this app — nothing is uploaded, and there is no analytics or tracking of any kind.
