ASK YOUR MEMORY SOURCES CONNECTED

Which database did we choose for EngramVault, and why?

WHAT YOUR MEMORY KNOWS

You chose embedded SQLite (vault.db) with FTS5 BM25 and 384-dim semantic vectors: zero external dependencies, full data sovereignty, and sub-millisecond local queries across macOS, Linux, and NAS.

Capture everything.

Curate what matters.

Keep the source.

THE INTERFACE

Search across every source at once.

One query surfaces facts, decisions, and evidence from all your conversations and documents — each linked to its original source.

THE PROBLEM

Your knowledge is everywhere. Its history should not be.

Important reasoning gets scattered across AI chats, Notion pages, project files, manuals, and passing decisions. Months later, search can find words, but not reliably explain what you chose or why.

AI conversations preserve the reasoning and alternatives.

Notes preserve intentions, plans, and deliberate summaries.

Documents add reference material and new evidence.

Decisions make the current choice explicit.

THE FLOW

Do not decide what to remember while you are learning it.

Capture

Conversations are archived automatically, so useful context is not lost because you forgot to save it.

Connect

Bring in the notes and documents that give your conversations a wider context.

Curate

Extracted facts and decisions are reviewed, while the original source remains available.

Recall

Ask what you chose, why you chose it, and what has changed since.

TRUST BY DESIGN

A source is not automatically a fact.

EngramVault separates what a source says from what you have confirmed. That makes it possible to remember your history without treating an old note or an AI answer as permanent truth.

EVIDENCE

A conversation, note, or document with provenance.

CLAIM

An attributed suggestion or unverified statement.

FACT

A current state you have confirmed.

DECISION

A choice that can be adopted, revised, or superseded.
