Capture
Keep a link, note, quote, or file, with retained capture history and source evidence.
Self-hosted second brain
Turn what you save into connected knowledge.
Arivu is a private knowledge workspace for links, notes, quotes, and files. Capture without ceremony, make connections you can inspect, and learn from material that stays on your server.
Capture. Connect. Discover. Learn.
Save first. Arivu gives you several ways to understand and revisit the material later, without forcing a filing system or model setup at the door.
Connect
Add explicit links and inspect relationships with visible sources.
Discover
Search the full text or explore a focused knowledge graph.
Learn
Return to useful material and evidence-backed patterns over time.
Meet your knowledge where the work happens.
Home
Use the persistent Pulse, Focus, Review, and Board switcher to move from orientation to follow-up.
Library
Browse bookmarks, notes, annotations, concepts, entities, and other saved knowledge together.
Notes
Write standalone and daily notes, then connect them directly to the material that informed them.
Graph
Focus a bounded map of typed relationships, provenance, and confidence, with a list alternative.
Insights
Inspect deterministic patterns such as emerging themes, forgotten value, and knowledge gaps.
Capture quickly. Find it again with context.
Global Capture keeps new material close. Search uses built-in full-text retrieval, while Ask builds cited answers from what you have saved. A model provider is optional.
Keep evidence private, or publish a deliberate snapshot.
Reader progress, capture history, and retained source artifacts help you return to research. Optional nested collections and ongoing RSS or Atom subscriptions add structure without making it a capture prerequisite.
Bounded preservation
Operators can optionally preserve screenshots or PDFs. The browser helper is disabled by default.
Point-in-time sharing
Create a secret-link copy that excludes private workspace fields, then list, expire, or revoke it.
Asset-aware recovery
Installer backups keep SQLite and the adjacent asset store together, with a manifest that restore verifies.
Straightforward to run. Straightforward to leave.
Arivu ships as one Go binary backed by SQLite. The guided installer handles a Linux VPS, and imports, exports, and backups keep your knowledge portable.
Useful without AI
Capture, explicit links, full-text search, graph structure, and deterministic insights work without a provider.
Optional enrichment
Add a compatible provider for improved summaries, embeddings, explanations, or synthesis when you want them.
Portable by design
Keep a comprehensible SQLite database, create backups, and move material through common import and export formats.
