I built Neurix to solve my own problem knowledge scattered everywhere (tabs, notes, docs, chats) with no way to connect the dots or actually ask questions across it all.

The core flow:

Highlight any text on the web right-click Neurix extracts a summary + keywords automatically

Those fragments get woven into a personal knowledge graph

Ask Neurix follows strict principles:

• Uses only your uploaded knowledge (and shared nodes you received)

• Retrieves nodes via relevance + recency + semantic intent

• Answers with source citations (verifiable, not magical)

• Uses external knowledge only with your permission (optional expansion)

• Let's you save great answers as new nodes to grow your graph

If you already have a graph: ask immediately.
If not, create your first few nodes + connections your graph will start forming.

I d love feedback from the community:
What makes retrieval feel trustworthy to you in the UI (sources, ranking explanation, confidence, etc.)?

Neurix now has a mobile PWA because remembering and connecting ideas doesn t happen only at your desk.

You re in the middle of work, studying, commuting you catch an insight and think I ll save it later.
Ten minutes later, it s gone. Not because you re lazy but because knowledge capture is an anytime need.

So I shipped a lightweight, app-like experience on your phone:

• No storage needed (no app download)

• Fast & minimal like an app

• Connected directly to the web version

I started as a math-focused student. I fell in love with logic the way numbers relate, the way patterns reveal structure, the way a single correct connection can make an entire problem suddenly make sense.

Then I took an unexpected turn in university: criminal investigation. On the surface, it looked far from math. But the deeper I went, the more familiar it felt. It was still logic just expressed differently: behavior linked to evidence, people linked to events, and everything mapped onto the framework of the law. Different domain, same essence: relationships.

That experience rewired the way I see knowledge. I began noticing invisible links across disciplines ideas flowing from one field to another even when most people treat them as unrelated. Patterns in human behavior can be modeled. Real-world phenomena can be abstracted. Systems can be understood through signals, constraints, and connections. Knowledge doesn t live in isolated folders it moves.

After years of learning and working, I returned to data and logic almost like coming home. Becoming a DBA and studying data science and AI gave that old obsession a clearer shape: I didn t just want to store information. I wanted to connect fragmented knowledge into a coherent picture.

Hi everyone I m Hoang, the solo founder of Neurix.

I kept running into the same problem: I save tons of notes (study, work, random ideas), but when I actually need something later, I either can t find it or I don t know what it connects to. So I started building Neurix as a second brain that s less about storing and more about retrieving + connecting.

What Neurix does (in plain terms)

Neurix turns each piece of content into a knowledge node:

Neurix doesn t just store notes it understands them first, then distills the essence so you can recall 70 80% of the key ideas anytime. Keywords become synapses that connect your knowledge.
