Notion is a polished all-in-one workspace. VaultBase takes a different approach — plain markdown files you actually own, RBAC that scopes AI access, decision traces with provenance, and a self-hostable server. No proprietary format, no vendor lock-in.

Notion stores everything in a proprietary database. Exports produce lossy markdown that drops formatting, relations, and metadata. If Notion changes pricing, removes features, or goes down, your data is trapped.
VaultBase is plain markdown files on disk — the same files you'd edit in VS Code,
Obsidian, or any text editor. Your knowledge base is a directory of
.md
files with YAML frontmatter. Back them up with Git, rsync, or any tool that
handles files. No export step, no conversion loss, no lock-in.
Notion AI costs $10/user/month on top of your plan and has access to everything in your workspace. There's no way to scope what the AI can see based on user roles — an intern's AI query could surface executive strategy docs.
VaultBase's MCP server enforces RBAC on every AI interaction. When an agent searches, reads, or writes, it operates within the calling user's permissions. Deny-wins logic means sensitive folders stay hidden regardless of which AI tool makes the request. Permission-scoped AI isn't an add-on — it's how the system works.
Notion is a document tool. It stores what you write but has no concept of why decisions were made, what inputs informed them, or whether they contradict prior choices. When someone asks "why did we choose Postgres over MySQL?", you search and hope someone documented it.
VaultBase decision traces capture the full chain: inputs read, policies applied, reasoning, outcome. The context graph links traces to source documents and flags when referenced docs change. Agents can query precedent decisions by type, tags, or text — and get provenance, not just keyword hits.
Notion is cloud-only. There's no self-hosted option, no on-premise deployment, and no way to keep data entirely within your infrastructure. VaultBase is a single Go binary licensed under AGPL-3.0 — run it on your own servers at zero cost, or use VaultBase Cloud starting at $4/mo for Personal, $12/mo for Team, or $50/mo for Business. Regulated industries, air-gapped networks, and data sovereignty requirements are first-class use cases, not afterthoughts.
Notion has earned its popularity. These are real strengths worth acknowledging.
If your team loves Notion's databases and all-in-one approach and doesn't need AI agent access or self-hosting, Notion is a solid tool. VaultBase is purpose-built for knowledge management with AI and access control at the core.
Notion's export produces markdown files that VaultBase can work with. Here's the migration path:
Notion's database views don't have a direct equivalent — those workflows may need restructuring. But your written knowledge, meeting notes, docs, and wikis transfer cleanly.
