Fast, low-friction capture
Capture thoughts by voice, text, or screenshot with one button and no required fields. The site says capture takes about four seconds and there is no folder or tag decision at save time.
Corteks
Corteks is a private-beta iOS app for capturing raw thoughts and having them organised and read back to you. It accepts voice, text, or screenshots, then analyses entries into summaries, tags, links, and weekly reflections grounded in your own history.
What Corteks is
Corteks is a private-beta iOS app for capturing raw thoughts and having them organised and read back to you. It is aimed at the moments when a thought appears quickly and would otherwise be forgotten: in the shower, mid-conversation, or while moving between tasks.
The product is built around spoken thoughts first, but it also accepts typed text and screenshots. Instead of asking you to choose folders or tags, Corteks analyses each entry, connects it to what you have already captured, and surfaces patterns through a thought graph, weekly readings, and conversation-style answers grounded in your own history.
Core features
On-device dictation
Speech-to-text runs on the device itself, so the audio never leaves the phone. The text is then sent for analysis rather than the raw recording.
Automatic analysis and linking
Each thought is titled, summarised, assigned a kind, and tagged automatically. Corteks also checks new thoughts against your earlier entries to find patterns and repeats.
Graph-based organisation
Captured thoughts are placed on a graph and connected to related items. The site describes this as closer to an AI mind map than a list.
Weekly reading of your thoughts
Corteks generates readings and a weekly story about your own thinking, including what you thought about most, what shifted, and what you keep circling.
History-grounded Q&A
You can ask questions grounded in your own history, and the app answers from what you have written rather than from the internet.
Common use cases
Capturing thoughts on the go
Use Corteks when an idea appears too quickly to sort into a folder. You can speak it immediately, then let the app title and categorise it later.
Reviewing patterns in your own thinking
Use it as a personal thinking log if you want to notice recurring themes, repeated concerns, or topics you keep circling over time.
Weekly reflection
Use the weekly story as a lightweight reflective check-in that summarises what you thought about most, what changed, and what stayed stuck.
Self-referential Q&A
Use the question feature when you want answers based on your own notes instead of search results, such as whether you have been avoiding something or repeating yourself.
Drafting without organising
Use the app to keep voice-driven notes without having to decide on tags or folders up front, which can be helpful when you want to capture first and organise later.
Pros and Cons
Pros
- Low-friction capture is central to the workflow, with voice, text, and screenshot input.
- The app automatically organises thoughts with titles, summaries, kinds, tags, and links to related entries.
- Weekly stories and readings add a review layer rather than leaving thoughts as a static list.
- Question answers are grounded in your own captured history, which helps keep responses tied to what you actually wrote.
- The privacy policy states that the app does not use advertising, analytics, or tracking software.
Cons
- It is in closed testing on iOS only, with Android deferred and no App Store release yet.
- Corteks is not end-to-end encrypted, which may matter for users who want the app itself unable to read their notes.
- Pricing has not been announced, and the service is free only during closed testing.
FAQ
What is Corteks used for?
Corteks is an app for capturing your own thoughts and having them organised and read back to you. You can capture spoken thoughts, typed text, or a screenshot, and the app analyses them into titles, summaries, kinds, tags, and links to related thoughts.
How does the capture workflow work?
Capture takes about four seconds. You speak, type, or drop in a screenshot, and the app handles the rest: speech-to-text runs on your device, then the text is analysed and added to your graph.
What platforms does Corteks support right now?
Corteks is available as a private beta on iOS only through a TestFlight waitlist. It is not on the App Store yet, and Android is deferred.
Does Corteks have pricing yet?
The app is free while it is in closed testing, and pricing has not been announced yet.
Is Corteks end-to-end encrypted?
No. The privacy policy says Corteks is not end-to-end encrypted by design, because the service needs to read your thoughts to produce readings, weekly stories, and chat answers. It does use TLS in transit and isolates rows per account.
