Works with Cursor, Claude Code, Windsurf, VS Code, and any MCP tool

Tired of re-explaining your codebase and projects to AI every single time?

ContextStream gives your AI assistant a memory that persists across sessions. Your decisions, your architecture, your preferences — remembered for as long as you need them.

Free tier includes 5,000 operations/month. Plenty for personal projects.

Quick Setup

See the magic in your next coding session

Three steps. Copy-paste config. Ask one question. Watch your AI actually remember.

1

Get your API key (30 seconds)

Sign up, go to Settings → API Keys, create one.

2

Add to your MCP config (60 seconds)

Paste this into your Cursor/Claude MCP settings:

{
  "mcpServers": {
    "contextstream": {
      "command": "npx",
      "args": ["-y", "@contextstream/mcp-server"],
      "env": {
        "CONTEXTSTREAM_API_KEY": "your-key-here"
      }
    }
  }
}
3

Ask this in your next chat (30 seconds)

Open Cursor or Claude, start a new chat, and type:

"Initialize session and remember that I prefer TypeScript with strict mode, and we use PostgreSQL for this project."

Then start a brand new conversation and ask:

"What are my preferences for this project?"

It remembers. Across sessions. For as long as you keep it.

Try closing the chat and coming back tomorrow — it still remembers.

Sound familiar?

"We literally just talked about this 10 minutes ago..."

Your AI claims to have memory, then asks you to re-explain how to run the app. ContextStream actually remembers — same chat, next chat, next month.

"Wait, why did we build it this way?"

Decisions are linked to the code they affect. Ask why, get the original reasoning AND the implementation.

"Let me explain the codebase... again."

New sessions auto-load your workspace context. Your AI already knows your stack, your patterns, your preferences.

"My Cursor memory doesn't help in Claude"

One memory layer that works across every MCP-compatible tool. Switch tools, keep your context.

Beyond Memory

Memory is just the start

ContextStream also understands your code — dependencies, impact, architecture.

Persistent Memory

Store decisions, preferences, and context. Searchable across sessions and tools.

Semantic Search

Find code by what it does, not just keywords.

Dependency Analysis

Know what depends on what before you refactor.

Knowledge Graphs

Connect decisions to code, docs to features.

Auto-Session Init

AI gets context automatically. No copy-pasting.

Private & Secure

Encrypted, never used for training. Self-host option.

Privacy First

Your Code Stays Yours

Encrypted, never used for training, and you control access. Enterprise can self-host for complete data sovereignty.

Encrypted at Rest

All data encrypted with AES-256

No Training on Your Data

We never use your code to train AI

You Control Access

Workspace permissions & API keys

Self-Host Option

Enterprise can self-host for full control

Stop repeating yourself.

Setup takes 2 minutes. Your AI remembers across sessions and tools.
