Second Brain Link vs Corteks

Second Brain Link turns the data you already own into a private, AI-queryable "digital twin" that lives entirely on your device. Your LinkedIn, Facebook, Instagram, and Google exports are unpacked, de-duplicated, and linked into one knowledge graph — right on your phone. Nothing is uploaded. There's no account, no tracking, and no cloud. WHAT YOU CAN DO • Build your brain from the data exports you request from each platform • Explore an interactive graph of the people, companies, and topics in your life • Talk to your twin — ask questions and get answers grounded in your own notes • Keep everything 100% on-device and private by design WHY IT MATTERS Your most valuable context — who you know, what you've done, what you care about — is trapped in export archives nobody ever opens. Second Brain Link hands it back to you, working. Your data already exists. It's already yours. It's time it started working for you.

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.
