# Own Your Context Layer (File Over App)

# Action: Own Your Context Layer (File Over App)

**Action:** Store AI memory in open formats (Markdown / SQL) rather than proprietary SaaS platforms.
**Outcome:** Ensures long-term data sovereignty and model-agnostic flexibility.

## Why

Do **not** lock your compounding organizational knowledge into a proprietary SaaS platform. Build your context layer using open, durable formats:

- **Markdown files** (e.g., via [[entity-obsidian]]) for the [[concept-ai-wiki]] approach.
- **Self-hosted SQL** (SQLite or Postgres) for the [[concept-openbrain-architecture]] approach.

This way you can swap out the underlying LLM models (OpenAI, Anthropic, local open-source models) as the technology evolves — see [[concept-file-over-app]].

## Anti-Patterns

- Storing your knowledge graph in a single vendor's chat history.
- Relying on a SaaS that may change pricing, alter privacy policies, or shut down.
- Allowing the AI's editorial decisions ([[concept-error-baking]]) to be the only record of your data.

## Compatibility

This principle is **shared by both [[concept-ai-wiki]] and [[concept-openbrain-architecture]]** — it is one of the few points where the two architectures fully agree.
