Sound Familiar?

These are real complaints from developers using AI coding tools every day.

🔄

Re-explaining Everything

Every time you switch from Claude Code to Cursor, you start from zero. The AI has no idea what you discussed 5 minutes ago.

"I kept pasting the same context into Cursor and Claude Code every time I switched machines."
🧠

Memory Doesn't Transfer

Claude remembers in Claude. Cursor remembers in Cursor. None of them share what they've learned about your project.

"None of them know what I've discussed with the others."
📋

Rule File Chaos

You maintain CLAUDE.md, .cursorrules, .windsurfrules — all saying the same thing. Update one, forget the others.

"Every time I update rules I have to change 4-5 files."
💸

Context Costs Money

Re-explaining your project burns tokens. Claude Code can spend $5 just understanding your codebase before writing a single line.

"Context windows are never big enough for anything that isn't a toy project."

Your Context, Synchronized

ContextSync creates a unified context layer that works with all your favorite AI coding assistants.

🔗

Unified Memory

Every decision, preference, and architectural choice you share with one AI tool becomes available to all of them.

📝

One Rule File

Write your coding rules once. ContextSync automatically compiles them for Claude Code, Cursor, Windsurf, and more.

🔒

Local-First Privacy

All memories stored locally on your machine. Your code context never leaves your computer unless you choose cloud sync.

⚡

Frequently Asked Questions

Why do I need ContextSync? Can't I just copy-paste context?

You can, but that's exactly the problem developers are complaining about. Every time you switch tools, you waste time re-explaining your project. ContextSync automates this so your AI assistants always understand your context.

Where is my data stored?

All memories are stored locally on your machine in SQLite. With the Free tier, nothing leaves your computer. Pro users can optionally enable cloud sync for cross-device access.

Which AI coding tools are supported?

12 tools and growing: Claude Code, Cursor, Windsurf, Gemini CLI, GitHub Copilot, Cline, Roo Code, Codex CLI, Aider, Continue, Zed, and Replit AI. Any tool that supports MCP protocol can be integrated.

Can I cancel my subscription anytime?

Yes, you can cancel anytime. Your Pro features will remain active until the end of your billing period. No questions asked.

How is this different from each tool's built-in memory?

Each tool's memory is siloed — Claude only knows what you tell Claude, Cursor only knows Cursor conversations. ContextSync creates a unified memory that all tools can access.
