Novyx Vault vs Obsidian

Both Novyx Vault and Obsidian use markdown as their native format, so your notes are always plain text files you can open anywhere. Both support wiki-links, backlinks, and an interactive knowledge graph for visualizing connections.

Where Obsidian pulls ahead is its massive plugin ecosystem. With over 1.5 million users and 2,000+ community plugins, you can customize Obsidian to do almost anything — from Kanban boards to spaced repetition. Obsidian also has polished mobile apps for iOS and Android, which Vault does not have yet.

Vault's editor is built on CodeMirror 6 with slash commands, live preview, and built-in AI writing tools like Brain Dump and Clip Remix that go beyond what Obsidian offers out of the box.

Obsidian recently introduced AI features, but they are stateless — the AI does RAG over your files without remembering previous conversations or building context over time. Each interaction starts from scratch.

Novyx Vault's AI is fundamentally different. It has true persistent memory that survives sessions, consolidates over time, and can be rolled back to any previous state. Ask about a project from last month and the AI responds with full context. It also discovers hidden connections between your notes (Ghost Connections), extracts entities and relationships, and offers a full memory timeline with audit trail.

Vault supports 20+ AI providers through BYOK (Bring Your Own Key), including OpenAI, Anthropic, Google Gemini, DeepSeek, Ollama, and local models via LM Studio. Obsidian's AI is limited to fewer provider options.

This is Vault's strongest differentiator. Powered by the Novyx SDK, Vault gives your AI a real memory layer — every interaction is remembered, timestamped, and versioned. You can browse the full timeline, verify the chain of memories, and roll back to any previous state.

Obsidian does not have an equivalent feature. Its AI works within the current session only, with no persistence between conversations.

Both tools respect privacy. Obsidian stores notes locally by default and offers end-to-end encrypted sync. Vault also stores notes locally in desktop mode as plain markdown files, and is fully self-hostable.

The key difference is openness. Vault is open source under the MIT license — you can read every line of code, contribute features, or fork the entire project. Obsidian is source-available but not open source — you can inspect the code, but you cannot modify or redistribute it. With Vault, you can verify and fork it.

Vault's BYOK model means your AI API keys never touch Novyx servers. They stay in your browser's local storage, giving you full control over which AI provider sees your data.

Obsidian is free for personal use, but sync costs $50/year and publish costs $8/month. These add up quickly if you use both. Commercial use requires a $50/year license per user.

Vault's free tier includes the full editor, wiki-links, knowledge graph, 20+ AI providers, cloud sync, and publishing. The $9/month Pro plan adds persistent AI memory, Ghost Connections, cortex insights, voice capture, and the full audit trail.

Obsidian has a mature, thriving community that has been growing since 2020. Its plugin and theme ecosystem is unmatched in the personal knowledge management space. If you need a specific workflow, there is probably a plugin for it.

Vault is newer and its community is just getting started. The advantage is that Vault is fully open source — you can contribute directly to the core product, not just build plugins on top of a closed platform. As the community grows, so will the ecosystem.
