Question 1

Why do I need ContextSync?

Accepted Answer

Every morning your AI relearns your project for 4 minutes — grepping files, asking 'where is X implemented?'. Switch tools and you re-explain everything from scratch. ContextSync gives every AI coding tool a self-managing context window so you stop repeating yourself.

Question 2

What does ContextSync solve?

Accepted Answer

Three things: (1) Memory across sessions — your AI remembers yesterday. (2) Memory across tools — what you taught Claude Code is available in Cursor. (3) Rules in sync — one rules.md compiles to CLAUDE.md, .cursorrules, AGENTS.md, .windsurfrules and 8 more formats.

Question 3

How does ContextSync sync context between AI tools?

Accepted Answer

ContextSync uses the Model Context Protocol (MCP) to provide a unified memory layer. It stores memories in a local SQLite database and exposes them through MCP tools. Each AI tool connects to the same memory store automatically.

Question 4

Where is my data stored?

Accepted Answer

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

Question 5

Which AI coding tools are supported?

Accepted Answer

10 AI coding tools supported today, all stable, all via Model Context Protocol: Aider, Claude Code, Cline, Codex CLI, Continue, Cursor, Gemini CLI, GitHub Copilot, Replit AI, Roo Code, Windsurf.

Question 6

What is the difference between Free and Solo Pro?

Accepted Answer

Free tier supports 2 AI tools on 1 device with local storage and 14-day memory retention. Solo Pro ($19/mo) unlocks all 10 supported AI tools, permanent memory, cloud sync across up to 3 devices, and the ability to save new memories from any tool.

Question 7

How does rule file sync work?

Accepted Answer

You write your coding rules once in ~/.contextsync/rules.md. ContextSync automatically compiles them to each tool's format: CLAUDE.md for Claude Code, .cursorrules for Cursor, .windsurfrules for Windsurf, and more. A background daemon watches for changes.

Question 8

Can I use ContextSync on multiple devices?

Accepted Answer

Free tier supports 1 device. Solo Pro supports up to 3 devices with cloud sync so your memories and rules automatically sync across all registered devices.

Question 9

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

Accepted Answer

Built-in memory is per-tool: Claude only knows Claude conversations, Cursor only knows Cursor. ContextSync creates a unified memory that all 10 supported tools can access, so context shared with one tool is immediately available to all others.

Question 10

Do you offer a team plan?

Accepted Answer

Team Pro is $49/user/mo in private beta for small teams that need seats, invites, team administration, and early shared-context workflows. Email support@yangqing.one to join.

Question 11

Can I cancel my subscription anytime?

Accepted Answer
