How NEXUS works

From raw links to structured, searchable knowledge in seconds.

1

Paste Anything

Drop in URLs, raw text, or bulk links. NEXUS scrapes and ingests everything automatically.

2

NEXUS Organizes It

AI generates summaries, smart tags, categories, and auto-assigns every source to a collection.

3

Discover Related Knowledge

Personalized recommendations appear based on your library, recent searches, and interests.

4

Ask Across Your Library

Semantic search + Claude synthesis answers any question using your saved knowledge.

Full Feature Set

Everything to think better

NEXUS brings together saving, organizing, discovering, and querying into one intelligent workflow.

Paste Anything

URLs, articles, tools, videos, raw text, or bulk pastes. One action to capture anything.

Smart Semantic Search

Vector-powered search finds sources by meaning, not just keywords. Works offline too.

Auto Collections

Collections form automatically from your library. AI groups related sources into named clusters.

Ask Your Library

Chat with your entire knowledge base. Get cited answers synthesized from your saved sources.

Discover Recommendations

Personalized tool and topic recommendations based on your library, interests, and usage.

Learning Paths

Curated stacks of related tools — Frontend, AI, Backend, Robotics — matched to your interests.

Knowledge Insights

AI analysis of your full library reveals focus areas, trends, and what to explore next.

Knowledge Gaps

NEXUS identifies adjacent topics you haven't saved yet — based on your existing interests.

Adaptive Recommendations

Like, dislike, or dismiss suggestions. NEXUS learns your preferences and refines its model.

Workspace Customization

Themes, background presets, library views, and filter/sort preferences. Your workspace, your way.

Responsible AI Layer

Built-in safety classification blocks harmful queries and flags restricted content automatically.

Discover Engine

Your library powers what you discover next

NEXUS builds a model of your interests from every source you save and every question you ask — then uses it to surface exactly what you should explore next.

"Because you saved…" recommendations

Every source you save trains what NEXUS suggests next.

Learning paths for your interests

Curated stacks of related tools matched to your exact profile.

Adjacent knowledge detection

Identifies related areas you haven't explored yet.

Like/dislike feedback loop

Thumbs up or dismiss any recommendation — NEXUS adapts.

Ask NEXUS influences Discover

Your questions shape future recommendations automatically.
