VaultGuard
Per-file permissions for your AI knowledge-base in Obsidian
Obsidian is the best thinking and knowledge-base tool ever built for one person. VaultGuard makes it work for a team. It adds encrypted sync, per-file permissions, share-links, AI chat, guest access and audit logs to the vault you already have — no migration, no new app to learn. You write exactly as you do today; VaultGuard protects who can view and work with the files. Point Claude or GPT at the vault and the AI inherits the same permissions your people do. Free if you self-host.
Hey Product Hunt 👋
I'm Aurel, one of the makers.
We ran our company on Obsidian and hit the wall every team hits. No permissions, no encryption, no audit trail. Whoever has the vault has everything, including after they leave.
So we built the fix. VaultGuard is live today and installs on the vault you already have.
🔐 End-to-end encryption (AES-256-GCM + KMS)
🔑 Per-file permissions
🚪 Keys revoked and files re-encrypted when someone leaves
📋 Admin panel and audit trail
No migration, nothing new to learn, set up in an afternoon. Still plain markdown underneath, so you can walk away with everything whenever you want.
Free and open source if you self-host. Paid plans if you'd rather we run it.
If you've ever tried sharing an Obsidian vault with your team, where did it break for you? That's what I'm here to hear today.
When your team works on multiple projects simultaneously, using AI efficiently while staying aligned is a real challenge. If your AI lacks context about your specific business, customers, or best practices, you end up with generic responses that add little value.
The solution is keeping all your documentation, know-how, and updates in a single place that both your team and AI can access.
However, this creates a new problem: how do you secure a central knowledge base containing sensitive data, track who has access to what, and restrict permissions when someone leaves?
We originally built VaultGuard as an internal tool to solve this exact problem. But after speaking with clients and potential customers, we realized nearly every company working with AI faces the same issue—so we decided to launch it as a product.
Quick tip: Don't worry if you don't have an internal knowledge base yet.
VaultGuard includes an integrated AI chat that connects directly to your existing Anthropic or OpenAI subscription.
This lets you:
Run pre-built commands (like /import-knowledge) from existing projects to set up your knowledge base in minutes.
Use built-in MCP tools to manage VaultGuard directly—setting permissions, controlling visibility, formatting documents, or getting context-aware answers to your questions.
If you have any questions or need help setting up a knowledge base for your business, just reach out! I’d be glad to help you get started.
P.S. We are also preparing webinars on this topic, so stay tuned!
