šŸ‘‹ Hey PH! I'm mamba, creator of Context Sync. The Problem I Solved: Ever spent at least 10 minutes re-explaining your project to Claude because you hit the context window limit or started a new chat? Or switched from Claude Desktop to Cursor and lost all your context? Yeah, me too. Every. Single. Day. What is Context Sync? It's an MCP (Model Context Protocol) server that gives AI assistants persistent memory. Your conversations, decisions, and project state sync across Claude Desktop, Cursor IDE, and any MCP-compatible tool. What makes it special: šŸ§  Cross-Chat Memory - Claude remembers your project across all conversations šŸ”„ Platform Sync - Switch between Claude & Cursor without losing context āœ… Todo Management - Track tasks with priorities, tags, and due dates šŸ” Code Intelligence - Analyze dependencies, call graphs, and types šŸ“Š 50+ Tools - Everything from file operations to git integration šŸ”’ 100% Local - All data stays on your machine (SQLite) v0.5.0 just launched with: Global todo list system (urgent/high/medium/low priorities) Smart filtering by status, tags, dates Overdue detection & due-soon alerts Cross-platform task sync Who's it for? Solo developers tired of repeating context, teams wanting consistent AI assistance, anyone building with Claude or Cursor who values their time. Try it: ```bash npm install -g @context-sync/server ``` Open source, MIT licensed, zero dependencies beyond Node.js. **I'd love feedback on:** - What other AI tools should we support? (VS Code? GitHub Copilot?) - What features would make this indispensable for your workflow? - Any bugs or rough edges in the setup process? Built this because I needed it. Hope it saves you as much time as it's saved me! Questions? Fire away! šŸš€

Great question from Reddit that I thought the PH community would find useful:

Q: "If you end up at a 200K token context window with Claude, how does Context Sync share context without saturating the new context window?"

A: This is the key difference from just copy-pasting context!

Context Sync doesn't dump your entire 200K conversation into the new chat. Instead, it stores structured context:

- Project metadata - Name, tech stack, architecture (< 500 tokens)

- Key decisions - "We chose PostgreSQL because..." (~100 tokens each)

- Active TODOs - Current tasks with priorities (~50 tokens each)

- File structure - What exists in your project (~200 tokens)

When you open a new chat, Claude gets a summary prompt (usually 1-3K tokens):

[ACTIVE PROJECT: TaskFlow]
Architecture: Next.js 14 + Supabase
Recent decisions:
- Using Server Actions for mutations
- Implementing optimistic UI updates
High priority TODOs:
- Refactor auth system (due Friday)

The best part is:

Claude can query MORE details via MCP tools if needed:

- "What decisions did we make about auth?" ā†’ pulls specific context

- You're not front-loading everything, just what's relevant

Think of it like a database vs loading everything into RAM. Claude queries what it needs, when it needs it.

Anyone else have questions about how this works under the hood? šŸš€

How did you succeed in publishing? Why can't I succeed?

@seagamesĀ Hey! Not sure I understand - are you trying to launch your own product on PH and having issues?
