PicoClaw AI Assistant
Skill by ara.so — Daily 2026 Skills collection.
PicoClaw is an ultra-lightweight personal AI assistant written in Go. It runs on $10 hardware with under 10MB RAM and boots in under 1 second. It supports multiple LLM providers (OpenAI-compatible, Anthropic, Volcengine), optional web search tools, and deploys as a single self-contained binary on x86_64, ARM64, MIPS, and RISC-V Linux devices.

# Start in background
docker compose -f docker/docker-compose.yml --profile gateway up -d
# View logs
docker compose -f docker/docker-compose.yml logs -f picoclaw-gateway
# Stop
docker compose -f docker/docker-compose.yml --profile gateway down
Docker: Web Console (Launcher Mode)
docker compose -f docker/docker-compose.yml --profile launcher up -d
# Open http://localhost:18800
Docker: One-shot Agent Mode
# Single question
docker compose -f docker/docker-compose.yml run --rm picoclaw-agent -m "What is 2+2?"
# Interactive session
docker compose -f docker/docker-compose.yml run --rm picoclaw-agent
Docker: Expose Gateway to Host
If the gateway needs to be reachable from the host, set:
PICOCLAW_GATEWAY_HOST=0.0.0.0 docker compose -f docker/docker-compose.yml --profile gateway up -d
Or set PICOCLAW_GATEWAY_HOST=0.0.0.0 in docker/data/config.json.
Termux (Android)
pkg install wget proot
wget https://github.com/sipeed/picoclaw/releases/download/v0.1.1/picoclaw-linux-arm64
chmod +x picoclaw-linux-arm64
termux-chroot ./picoclaw-linux-arm64 onboard
Quick Start
1. Initialize
picoclaw onboard
This creates ~/.picoclaw/config.json with a starter configuration.
2. Configure ~/.picoclaw/config.json
{
"agents": {
"defaults": {
"workspace": "~/.picoclaw/workspace",
"model_name": "gpt-4o",
"max_tokens": 8192,
"temperature": 0.7,
"max_tool_iterations": 20
}
},
"model_list": [
{
"model_name": "gpt-4o",
"model": "openai/gpt-4o",
"api_key": "$OPENAI_API_KEY",
"request_timeout": 300
},
{
"model_name": "claude-sonnet",
"model": "anthropic/claude-sonnet-4-5",
"api_key": "$ANTHROPIC_API_KEY"
},
{
"model_name": "ark-code",
"model": "volcengine/ark-code-latest",
"api_key": "$VOLCENGINE_API_KEY",
"api_base": "https://ark.cn-beijing.volces.com/api/coding/v3"
}
],
"tools": {
"web": {
"brave": {
"enabled": false,
"api_key": "$BRAVE_API_KEY"
},
"tavily": {
"enabled": false,
"api_key": "$TAVILY_API_KEY"
}
}
}
}
Never hard-code API keys. Reference environment variables using
$VAR_NAMEnotation in config, or set them in your shell environment before launch.
3. Run
# Interactive chat
picoclaw
# Single message
picoclaw -m "Summarize the latest Go release notes"
# Use a specific model
picoclaw -model claude-sonnet -m "Refactor this function for clarity"

Common Patterns
Pattern: Minimal $10 Device Setup
For a LicheeRV-Nano or similar ultra-low-resource board:
# Download the RISC-V or ARM binary from releases
wget https://github.com/sipeed/picoclaw/releases/download/v0.1.1/picoclaw-linux-riscv64
chmod +x picoclaw-linux-riscv64
# Initialize
./picoclaw-linux-riscv64 onboard
# Edit config — use a lightweight model, low max_tokens
cat > ~/.picoclaw/config.json << 'EOF'
{
"agents": {
"defaults": {
"workspace": "~/.picoclaw/workspace",
"model_name": "gpt-4o-mini",
"max_tokens": 2048,
"temperature": 0.5,
"max_tool_iterations": 10
}
},
"model_list": [
{
"model_name": "gpt-4o-mini",
"model": "openai/gpt-4o-mini",
"api_key": "$OPENAI_API_KEY",
"request_timeout": 120
}
]
}
EOF
./picoclaw-linux-riscv64
Pattern: Full-Stack Dev Assistant with Web Search
{
"agents": {
"defaults": {
"workspace": "~/projects",
"model_name": "claude-sonnet",
"max_tokens": 8192,
"temperature": 0.3,
"max_tool_iterations": 30
}
},
"model_list": [
{
"model_name": "claude-sonnet",
"model": "anthropic/claude-sonnet-4-5",
"api_key": "$ANTHROPIC_API_KEY",
"request_timeout": 600
}
],
"tools": {
"web": {
"tavily": {
"enabled": true,
"api_key": "$TAVILY_API_KEY"
}
}
}
}
Pattern: Docker with Environment Variables
# docker/docker-compose.override.yml
services:
picoclaw-gateway:
environment:
- OPENAI_API_KEY=${OPENAI_API_KEY}
- ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY}
- TAVILY_API_KEY=${TAVILY_API_KEY}
- PICOCLAW_GATEWAY_HOST=0.0.0.0
export OPENAI_API_KEY=sk-...
export ANTHROPIC_API_KEY=sk-ant-...
docker compose -f docker/docker-compose.yml -f docker/docker-compose.override.yml --profile gateway up -d
Pattern: Build for a Specific Target in Go
# Cross-compile for MIPS (OpenWRT routers)
GOOS=linux GOARCH=mips GOMIPS=softfloat go build -o build/picoclaw-linux-mips ./cmd/picoclaw
# Cross-compile for 32-bit ARM (older Raspberry Pi)
GOOS=linux GOARCH=arm GOARM=7 go build -o build/picoclaw-linux-arm ./cmd/picoclaw
# Cross-compile for RISC-V 64-bit
GOOS=linux GOARCH=riscv64 go build -o build/picoclaw-linux-riscv64 ./cmd/picoclaw
Troubleshooting
Binary won't execute on device
# Verify the binary matches the device architecture
file picoclaw-linux-arm64
uname -m # Should match: aarch64 = arm64, x86_64 = amd64
# Ensure executable permission
chmod +x picoclaw-linux-arm64
"Permission denied" on Termux
Termux requires proot for some system calls:
pkg install proot
termux-chroot ./picoclaw-linux-arm64 onboard
API key not recognized
- Do not use
"api_key": "sk-..."literals in config — set env vars and reference them as"$OPENAI_API_KEY". - Verify the env var is exported in your current shell:
echo $OPENAI_API_KEY.
Docker gateway not reachable from host
Set PICOCLAW_GATEWAY_HOST=0.0.0.0 in the environment or in config.json before starting the container.
High memory usage in recent versions
The project notes that recent PRs may push RAM usage to 10–20MB. If this is a concern on ultra-low-memory devices, pin to an earlier release tag:
git checkout v0.1.1
make build
Config file location
Default: ~/.picoclaw/config.json
Override at runtime:
picoclaw -config /path/to/custom-config.json
Rebuild after dependency changes
cd picoclaw
make deps
make build
