SYNQ

Your AI forgets. SYNQ makes it remember.

Every time you open a new chat, your AI starts from zero. SYNQ gives your AI persistent, cross-session memory.

Works with Claude · ChatGPT · Gemini · DeepSeek — and Claude Code · Cursor · Windsurf via MCP.

Try SYNQ in 30 Seconds

Don't have Docker? No problem. Use the new Zero-Docker (SQLite) mode for a one-click setup.

Fastest path (macOS/Linux):

1. Install Docker Desktop + Ollama + Node 20
2. git clone https://github.com/Eshaan-Nair/Synq && cd Synq && ./install.sh
3. Load extension/dist as unpacked Chrome extension
4. Open Claude/ChatGPT → click SYNQ badge → Save Chat

⏱ First install: ~5 min (model download included)

---

The Problem

You're deep into a complex project. You've had 12 conversations with Claude about your architecture, your auth flow, your database schema. Then you open a new chat — it's all gone.

SYNQ captures your conversations, distills them into a semantic knowledge graph, and automatically injects the most relevant context into every new prompt.

Key Features

Feature	Description
Hybrid Search RAG	Combines Vector search with Knowledge Graph facts for 2x better accuracy
Auto-Connect	Intercepts every prompt and injects relevant context automatically
100% Local	Ollama runs embeddings and extraction on your machine — nothing leaves your network
Zero Data Loss	Sliding window chunker preserves every word — no filtering, no minimum length
Prompt Injection Defence	Chunks scanned for injection patterns; context wrapped in XML delimiters
Knowledge Graph	22 entity types, 20+ relation types — captures technical and personal context
D3.js Dashboard	Force-directed graph with degree-scaled nodes, hover tooltips, zoom controls
MCP Evolution	Smart project detection + Hybrid recall in Claude Code, Cursor, Windsurf
Resilient Selectors	5-strategy fallback per platform; weekly CI detects when selectors go stale
Lite Mode	Runs on 4 GB RAM machines — skips Neo4j, RAG still works fully

---

System Requirements

Mode	RAM	Disk	Docker?	What runs
Full	8 GB+	15 GB+	Required	All features — Neo4j, MongoDB, ChromaDB, Ollama
Lite	4 GB+	10 GB+	Required	RAG only — MongoDB, ChromaDB (no knowledge graph)
SQLite	2 GB+	5 GB+	❌ Not needed	All features — single .db file + Ollama

No Docker? Use SQLite Mode

Set SYNQ_STORAGE_MODE=sqlite in backend/.env before starting. The installer detects Docker automatically and sets this for you if Docker is missing.

All launchers (start.bat, start.sh, install.bat, install.sh) auto-detect RAM and choose the right mode. Override with SYNQ_PROFILE=full or SYNQ_PROFILE=lite.

---

Quick Start

Prerequisites

Requirement	Version	Link
Docker Desktop	24.0+	docker.com — enable WSL2 on Windows
Node.js	20 LTS+	nodejs.org
Ollama	Latest	ollama.com
Groq API Key	—	console.groq.com — free, only needed if Ollama is unavailable

First-time Setup

Windows — double-click install.bat

Checks Docker + Node.js, opens Ollama download if missing,
pulls models, installs npm deps, builds all packages,
detects RAM, starts Docker with the correct profile.

**Configure API Keys** (Optional)
Copy `backend/.env.example` to `backend/.env` and add your `GROQ_API_KEY` for faster extraction if Ollama is slow or unavailable.

macOS / Linux:

git clone https://github.com/Eshaan-Nair/Synq.git
cd Synq
chmod +x install.sh && ./install.sh

Daily Use

Windows:        start.bat
macOS/Linux:    ./start.sh

Load the Extension

1. Open Chrome → chrome://extensions
2. Enable Developer mode (top-right toggle)
3. Load unpacked → select Synq/extension/dist
4. The SYNQ badge appears on Claude, ChatGPT, Gemini, and DeepSeek

Dashboard

Start the backend, then open http://localhost:3001

The dashboard is a production build served by the backend — no separate window needed.

---

MCP Server

v1.4.2 — SYNQ now works in any MCP-compatible AI tool.

Build the backend first:

cd backend && npm run build

Add to your AI tool's config:

Claude Desktop (~/.claude/claude_desktop_config.json):

{
  "mcpServers": {
    "synq": {
      "command": "node",
      "args": ["/path/to/Synq/backend/dist/mcp/server.js"]
    }
  }
}

Cursor / Windsurf (.cursor/mcp.json in project root):

{
  "mcpServers": {
    "synq": { "command": "node", "args": ["/path/to/Synq/backend/dist/mcp/server.js"] }
  }
}

Available tools: recall_context · store_memory · search_memory · list_projects · get_project_summary

Usage Guide

Saving a Conversation

1. Have a conversation on Claude, ChatGPT, Gemini, or DeepSeek
2. Click the SYNQ icon in the toolbar
3. Enter a project name and click Save Chat
4. SYNQ scrubs PII, chunks, embeds locally, and extracts graph triples — typically under 5 seconds

Auto-Connect

Once a session is active, SYNQ auto-attaches on every page load. Just type — context is prepended automatically. Click Pause in the popup to suspend. Click again to resume.

Classic Inject

Click Inject Context (one-time) to paste the knowledge graph summary directly into the chat input for manual sending. Useful for priming a cold start.

Dashboard

Open http://localhost:3001:

Tab	Content
Graph	D3.js force graph — hover nodes for connections
History	All semantic triples with timestamps
Chat	Full conversation with color-coded bubbles

---

How It Works

1. CAPTURE
   Save Chat → scrape conversation → FNV-1a deduplication

2. PRIVACY SCRUB
   API keys, JWTs, emails, connection strings → [REDACTED]
   Done in the browser before transmission

3A. VECTOR TRACK                    3B. GRAPH TRACK
    Sliding window chunker               Ollama llama3.1:8b
    300 words / 80 overlap               (Groq fallback if unavailable)
    Ollama embeddings                    summarize → extract triples
    ChromaDB cosine storage              Neo4j MERGE

4. AUTO-CONNECT (every prompt)
   Intercept → ChromaDB cosine search
   → sanitizeChunks() — injection patterns redacted
   → wrapInContextBlock() — XML delimiters
   → top-3 chunks prepended → sent to AI

Privacy and Security

All data lives in local Docker volumes. Nothing syncs externally.

Ollama is the primary extraction backend — fully local. Groq is an automatic fallback only if Ollama is unavailable, with a console warning.

Control	Detail
Prompt injection defence	Chunks scanned + XML context delimiters
PII auto-redaction	API keys, JWTs, emails, connection strings
Rate limiting	200 req/min global · 10 req/min on /api/chat/save
CORS	localhost:3001, localhost:5173, chrome-extension:// only
Input validation	sessionId as ObjectId, platform as enum, text length enforced
Security headers	helmet on every response
Shared secret	Optional X-SYNQ-Secret header

See SECURITY.md for the full threat model and vulnerability reporting policy.
