What is Continuity?

Continuity is a RAG-based synthetic memory system for AI coding assistants. It captures architectural decisions, tracks documentation changes, and provides persistent context across sessions - solving the problem of AI assistants "forgetting" previous conversations.

Installation

What Happens on First Launch

After installation, everything is automatic:

• Zero-click tool setup — auto-detects your AI tools (Claude Code, Cursor, GitHub Copilot, Google Gemini, and more) and configures synthetic memory access
• Smart Node.js resolution — finds Node.js automatically for nvm, fnm, volta, and Homebrew users
• Initial Project Scanner — scans your codebase and creates draft decisions for tech stack, dependencies, database, testing, deployment, API style, and project structure
• Git seeding — pre-populates decisions from your recent commit history so the sidebar is never empty
• A .continuity/ folder is created with your decisions as plain JSON — commit it to git and share with your team

Activation

After purchasing, you'll receive a license key via email. Activate it in VS Code:

1. Press Cmd/Ctrl+Shift+P
2. Type "Continuity: Activate License"
3. Enter your license key and email

License Types

What is MCP?

Continuity uses the Model Context Protocol (MCP) as a communication layer to provide AI assistants like Claude, Cursor, and Copilot with persistent memory and decision logging capabilities.

Available Memory Tools

Continuity ships profile-based synthetic memory tool sets for logging, searching, analyzing, and managing architectural decisions. Current profiles expose 9 core tools, 25 standard tools, or 36 full tools depending on the client and install mode.

Device Management

Why is Continuity more efficient than CLAUDE.md?

CLAUDE.md loads ALL decisions into context every session (O(n) complexity - grows linearly). Continuity uses semantic search to retrieve only relevant decisions (O(1) complexity - constant). At 1,650 decisions, CLAUDE.md needs 336,704 tokens while Continuity uses just 14,472 tokens. That is a 95.7% token reduction with a 23.3× efficiency advantage, and CLAUDE.md is already beyond the 200K context window.

What happens when I have more than 968 decisions?

Around 968 decisions, CLAUDE.md reaches the 200K context window and stops fitting reliably. Continuity keeps working because it only retrieves the relevant decisions needed for the current session.

How much money will I save?

Based on the current benchmark at 600 sessions/month: CLAUDE.md costs $606.07/month while Continuity costs $26.05/month. That is $580.02/month or $6,960.21/year in benchmark-model savings.

Is my data secure?

Yes. All decisions are stored locally in your project's .continuity/ folder. License validation uses encrypted HTTPS connections, and we never store your decision data on our servers.

What AI assistants does Continuity work with?

Continuity works with any AI assistant through its synthetic memory system: Claude Code, Cursor, GitHub Copilot, Google Gemini, and more. Zero-click setup auto-detects your installed tools and configures memory connections automatically.
