Introducing ContextFS: Persistent Memory for AI Agents

Today we're launching ContextFS, an open-source memory layer that gives AI assistants the ability to remember context across sessions, tools, and devices.

Introducing ContextFS: Persistent Memory for AI Agents

AI assistants are incredibly powerful, but they have a fundamental limitation: they forget everything between sessions. Every time you start a new conversation, you're starting from scratch. Your AI doesn't remember your project architecture, your coding preferences, or the decisions you made yesterday.

Today, we're launching ContextFS to solve this problem.

The Problem

If you've spent time working with AI coding assistants like Claude, GPT, or Cursor, you've probably experienced this frustration:

  • Repeatedly explaining your project structure
  • Re-teaching coding conventions and preferences
  • Losing context on multi-day projects
  • Copy-pasting the same background information

This isn't just annoying—it's a fundamental barrier to AI assistants becoming true long-term collaborators.

Our Solution

ContextFS is a universal memory layer that works across all your AI tools. It provides:

Local-First Storage

All your memories are stored locally in SQLite and ChromaDB. Your data never leaves your machine unless you explicitly enable cloud sync.

Semantic Search

ContextFS uses sentence-transformers to generate embeddings for semantic search. Find relevant context even when you don't remember the exact words you used.

Multi-Tool Support

Works with Claude Desktop, Claude Code, VS Code, Cursor, and any tool that supports MCP (Model Context Protocol).

Cloud Sync (Optional)

Sync your memories across devices with end-to-end encryption. We can't read your data—only you can.

Getting Started

Install ContextFS with pip:

pip install contextfs

Save your first memory:

contextfs save "Use PostgreSQL for production, SQLite for tests" -t decision

Search your memories:

contextfs search "database"

What's Next

This is just the beginning. We're working on:

  • Team workspaces for shared context
  • IDE plugins for VS Code and JetBrains
  • Automatic indexing of codebases
  • Memory evolution for updating knowledge over time

Open Source

ContextFS is open source under the MIT license. We believe developer tools should be transparent and community-driven.

Check out the code on GitHub and let us know what you think!
