Your Visual Intelligence Universe.
Stop organizing notes in flat folders. Build your exocortex with interactive 3D neurons, AI-powered clusters, and shared intelligence.
Folders are for files. Your brain works in connections.
Static hierarchies. Notes buried in folders. No way to see how ideas link across projects. Your second brain stays flat - and forgettable.
A living, breathing 3D neural network. Neurons, sources, and impulses connected visually. Fly through your knowledge and watch AI surface hidden connections in real time.
Built for how you think
One visual intelligence layer for your notes, research, and ideas.
3D Graph Visualization
Fly through your knowledge in 3D. Connect neurons, sources, and impulses as a living network.
Neural Core (AI Chat)
Chat with your universe. RAG-powered AI finds hidden connections and answers in milliseconds.
AI Semantic Search
Find ideas by meaning, not just keywords. Search the way your brain associates concepts.
Pathfinder & Zen Mode
Focus and navigate your graph with clarity. Pathfinder and Zen Mode keep you in the flow.
Browser Web Clipper
Save pages and ideas from the web straight into your graph. One click to add a new neuron.
Time Machine & Evolution Journal
See how your knowledge evolved over time. Revisit past states and track the growth of your universe.
Shared Universes
Publish clusters as interactive 3D worlds. Share your universe with others to explore.

Why I built Nervia
I was tired of losing my best ideas in endless folders. I wanted a tool that worked the way my brain actually works - through connections and visual patterns. I built Nervia to be my personal exocortex. Now, I'm opening the universe for you to build yours.
- Founder of Nervia
Frequently asked questions
What is a Neuron?
A Neuron is a single unit of knowledge - a note, a bookmark, a source, or an idea - that lives in your graph. You connect neurons to each other; clusters form automatically as related ideas group together.
What is the difference between 2D and 3D graph?
Genesis includes a 2D knowledge graph to build and explore your connections. Singularity unlocks the full 3D graph: fly through your knowledge in 3D, zoom into clusters, and navigate your universe spatially.
How do I sign in?
You can sign in with Google, GitHub, or Magic Link (email). No password required for Magic Link - we send you a one-time link to access your account.
What is the Neural Core?
The Neural Core is Nervia's AI layer (Singularity tier). It uses RAG over your graph so you can chat with your knowledge: ask questions, get summaries, and surface connections across your neurons in real time.
