# What I'm NOT doing

> Negative space matters more than the positive list when the work is wide. Pinning this somewhere I'll re-read.

## What I'm not building

- **A vector store.** We use pgvector because Postgres was already in the stack. We are not in the business of competing with Pinecone / Weaviate / Chroma. If pgvector ever becomes the bottleneck, we'll swap. We won't try to be the vector DB.
- **A knowledge graph DB.** Same logic. concept_index + concept_relations live in Postgres tables. We never sell anyone on "a graph database for AI memory" — that's not the product.
- **A fine-tuned model.** Every model we use is off-the-shelf (Anthropic Haiku, OpenAI text-embedding-3-small, GPT-4o-mini for capture, Claude Sonnet for analysis). Custom training is not on the roadmap for v6 or v7.
- **An AI provider.** Obvious but worth stating. We are not building inference infra.
- **A workspace.** No team channels, no rich-text collaboration, no comments threads. Hub-shaped, URL-shaped, single-author by default.
- **A comments system.** A lot of users will ask. The answer is no — comments turn a memory layer into a social tool, and the two have different incentive shapes.

## What I'm not chasing

- **The Notion shape.** Blocks, databases, embedded widgets, real-time collab. Notion does that better than we ever could; we're not in that lane.
- **The Roam shape.** Block-level references, bi-directional links as first-class, daily notes as the entry point. The audience is too narrow and the model is too far from URL-as-memory.
- **The Obsidian shape.** Local file vault, plugin ecosystem, vault-as-product. We're URL-shaped; the Obsidian shape requires we run on disk.

## What I'm not optimising

- **Conversion rate.** Not at this stage. The product has to be the story before the funnel matters.
- **MAU.** The wrong vanity metric for a memory tool — single-user retention over weeks is more meaningful than concurrent monthly users.
- **Viral coefficient.** I care that the dogfood loop works; I don't care about K-factor math.

## What I'm not delaying

- **Security review.** Even at this stage, a bug in shared-doc permissions is a launch-killer. Every PR touching auth or sharing gets a security pass.
- **Founder dogfood.** I have to live in mdfy.app full time. If I drift to using Notion for my own notes, the product gets worse.
- **The Show HN draft.** It gets rewritten every two weeks until launch.
