[ What It Does ]

[>_]

Remember Everything

Save decisions, bugs, insights, and context. Everything persists across sessions — nothing gets lost.

{..}

Hybrid Search

BM25 keyword search + semantic vector embeddings, merged with Reciprocal Rank Fusion. Find anything instantly.

</>

Git Intelligence

Auto-index commits, track file co-changes, and extract codebase DNA. Your repo’s history becomes searchable context.

>>>

Session Continuity

Three lifecycle hooks inject context at start, capture it at end. Claude picks up exactly where you left off.

[!]

Rules Engine

Define permanent rules enforced every session. Commit-msg hooks block violations, stop hooks scan for breaches. Hard and soft enforcement built in.

{~}

Zero Cloud

100% local SQLite with WAL mode. Your data never leaves your machine. No accounts, no subscriptions, no tracking.

[ How It Works ]

>_
Session Start

Context Injection

Synaptic injects rules, recent memory, git context, predicted focus, and rule violation warnings. Claude knows what you were doing before you even say a word.

{}
During Session

Live + Passive Capture

14 MCP tools for explicit saves, plus automatic transcript scanning that classifies your conversation and captures insights passively — no manual effort required.

>>
Session End

Auto-Distill

Synaptic creates a handoff summary, classifies intent, detects corrections as enforced rules, consolidates duplicates, and bumps access on referenced entries.
