๐ง Kai
Your AI copilot's memory. Persistent context across sessions, projects, and teams.
Give your coding agent the context it needs โ automatically.
Works with Claude Code ยท more copilots coming soon
The Problem
Every time you start a new conversation with your AI copilot, it forgets everything.
- ๐ You repeat the same context about your project, your team, your standards
- ๐คท The copilot makes mistakes you've already corrected in past sessions
- ๐ Your policies, specs, and business rules sit in files the copilot never sees
- ๐ง Decisions and rationale from past conversations are lost forever
Copilots are powerful โ but they have amnesia.
The Solution
Kai gives your copilot a persistent memory that grows smarter over time.
| Without Kai | With Kai |
|---|---|
| Copilot starts fresh every session | Copilot remembers what it learned |
| You repeat context manually | Context surfaces automatically |
| Knowledge lives in your head | Knowledge lives in a structured KB |
| Decisions are forgotten | Decisions persist across sessions |
How it works: Kai runs as an MCP server alongside your copilot. You teach it your context once โ policies, specs, decisions, patterns โ and it proactively surfaces relevant information when you need it.
๐ All data stays local. Your code and context never leave your machine.
Quickstart (Claude Code)
Step 1: Add Kai to Claude Code
claude mcp add kai -s user -e ANTHROPIC_API_KEY="your-anthropic-api-key" -- npx @aurite-ai/kai
Scope options:
-s projectโ Config stored for current project only-s userโ Config stored globally (available across all projects)
Step 2: In any project, tell your copilot:
"Set up Kai"
This deploys copilot rules and runs onboarding. The copilot asks a few questions to understand your context โ this only happens once.
Step 3: Start teaching it your context:
"learn ~/Downloads/api-guidelines.pdf"
"learn the docs/ folder"
Step 4: Start working โ Kai surfaces the right context automatically.
๐ฆ More installation options (npm global, Docker, from source)"build a customer support agent"
Kai feeds your copilot your API conventions, auth patterns, and related context. No reminders needed.
npm (Global Install)
npm install -g @aurite-ai/kai
Configure your MCP client to use kai-mcp as the command.
npx (No Install)
npx @aurite-ai/kai
Docker
docker pull kai/mcp
docker run -i kai/mcp
From Source
git clone https://github.com/Aurite-ai/kai.git
cd kai
pnpm install
pnpm --filter @aurite-ai/kai build
pnpm --filter @aurite-ai/kai bundle
What It Looks Like
You teach Kai your company's context:
"learn ~/docs/api-guidelines.pdf"
"learn the docs/ folder"
Later, you start a task:
"build a customer support agent"
Kai automatically surfaces the relevant context to your copilot:
- โ Your API conventions and auth patterns
- โ Customer data models and access policies
- โ Error handling and response format standards
- โ Related endpoints already in the codebase
Your copilot builds it right the first time โ no reminders needed.

How It Compares
| Feature | Kai | Copilot Memory | RAG Tools | Manual Context |
|---|---|---|---|---|
| Persists across sessions | โ | Partial | โ | โ |
| Learns from files & conversations | โ | โ | Files only | N/A |
| Proactive context surfacing | โ | โ | Query-based | โ |
| Auto-classifies knowledge | โ | โ | โ | Manual |
| Works across projects | โ | โ | Varies | โ |
| Zero-config for copilot | โ | โ | โ | โ |
| Data stays local | โ | โ | Varies | โ |
Kai is not a replacement for built-in copilot memory โ it's what copilot memory should have been.

Migrating from Kahuna
Kai was previously named Kahuna. Kai does not read any of the old Kahuna paths or settings, so everyone with an existing install needs to do these steps once.
Before you start: check that
~/.kahunaholds Kai data (knowledge/,integrations/,connectors/,.env) and not files from another Kahuna project.
1. Update your local clone (contributors only)
git remote set-url origin https://github.com/Aurite-ai/kai.git
git checkout main && git pull
pnpm install
pnpm clean && pnpm build
2. Move your data directory
mv ~/.kahuna ~/.kai
3. Rename environment variables and secrets
Every KAHUNA_* variable is now KAI_* (for example, KAHUNA_KNOWLEDGE_DIR is now KAI_KNOWLEDGE_DIR).
# Secrets stored by Kai
sed -i '' 's/KAHUNA_/KAI_/g' ~/.kai/.env
# Local MCP server config (contributors only)
sed -i '' 's/KAHUNA_/KAI_/g; s/\.kahuna-knowledge/.kai-knowledge/g' apps/mcp/.env
# Find leftovers in your shell profile, then rename them by hand
grep -n KAHUNA_ ~/.zshrc ~/.bashrc ~/.profile 2>/dev/null
On Linux, use
sed -iinstead ofsed -i ''.
If you used apps/mcp/scripts/setup-claude.sh, also rename the repo-local knowledge base: mv .kahuna-knowledge .kai-knowledge.
4. Re-register the MCP server
Remove the old server:
claude mcp remove kahuna -s user
claude mcp remove kahuna -s project
Then add Kai back, using the published package or your local build:
# Published package
claude mcp add kai -s user -e ANTHROPIC_API_KEY="your-anthropic-api-key" -- npx @aurite-ai/kai
# Local build of this repo (contributors)
pnpm mcp:setup
Restart Claude Code, run claude mcp list, and confirm kai is connected and kahuna is gone.
5. Update projects that use Kai
Tool names changed from kahuna_* to kai_* (for example, kahuna_learn is now kai_learn). In each project where Kai was set up:
[ -d .kahuna ] && mv .kahuna .kai # usage history and context guide
[ -f .kahuna-test.json ] && mv .kahuna-test.json .kai-test.json # test projects only
Then refresh the copilot rules so they use the new tool names. kai_initialize skips files that already exist, so run it with overwrite:
- Commit or back up any rules you customized (for example,
.claude/CLAUDE.md). - Tell your copilot: "Run kai_initialize with overwrite=true"
- Review the changes with
git diffand restore any customizations.
Also replace any .kahuna entries in the project's .gitignore with .kai.
6. Verify
ls -d ~/.kahuna 2>/dev/null
grep -n KAHUNA_ ~/.kai/.env apps/mcp/.env 2>/dev/null
Neither command should print anything.
