Capture
Keep a link, note, quote, or file, with retained capture history and source evidence.
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, Library, Notes, Graph, and Insights each answer a different question. Capture and Search stay global, so collecting or finding knowledge never depends on where you are.
Explore all featuresHome
Use Pulse, Focus, Review, and Board to move from orientation to follow-up.
Library
Browse saved and authored material first, then open generated concepts and entities.
Notes
Write standalone and daily notes, then connect them to the material that informed them.
Graph
Focus a bounded map of typed relationships, provenance, and confidence.
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.
Capture and Library guide
Keep evidence private, or publish a deliberate snapshot.
Reader progress, capture history, local article images, 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.
Complete background capture
Fresh installer deployments can preserve rendered evidence, local images, screenshots, and offline HTML, with a core-only opt-out.
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.
Search and Ask
Find saved text locally, or ask for a cited answer from material you already keep.
Straightforward to run. Straightforward to leave.
The core Arivu app ships as one Go binary backed by SQLite. The guided installer can also manage an isolated native capture runtime, while imports, exports, and backups keep your knowledge portable.
See data portabilityUseful 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.
Keep your knowledge on a server you control.
Arivu is open source, self-hosted, and useful before you connect a model provider.
