What is this?

wtf is a terminal AI assistant that is there for you when you f up. Hit an error? Just type wtf. Made a mistake? Just say wtf undo. Need to install something? Type wtf install [thing]. Forget the command? No problem just ask wtf can you back me out of this failed merge attempt?.

No flags to remember. No manual pages to consult. Just describe what you want.

Who is wtf for?

Non-engineers

More and more people are now able to work with code and command lines: data analysts using git for dbt models, designers and product managers vibe coding prototype features, marketers working with static sites. wtf helps with setups, remembering commands, and gets them out of jams.

Engineers

There are so many tools and commands to remember. You get stuck, you make mistakes, you get slowed down having to go read docs or switch over to ask your llm of choice. But now you can just stay in your terminal and have it answer or even fix your problems as they come up.

Installation

Via curl (recommended)

One-liner with automatic collision detection:

curl -sSL https://raw.githubusercontent.com/davefowler/wtf-terminal-ai/main/install.sh | bash

Via pip

pip install wtf-ai

From source (for development)

git clone https://github.com/davefowler/wtf-terminal-ai.git
cd wtf-terminal-ai
pip install -e .

Quick Start and Examples

First use: Just run wtf with any query. Setup happens automatically:

# First time use - setup wizard runs automatically
wtf "what's in my git status?"

# After setup, use naturally
wtf how do I exit vim

# Made a mistake?
wtf undo

# Install something
wtf install express

# Explain an error
wtf "what does this error mean?"

# Learn your preferences
wtf remember I prefer npm over yarn and I live in San Francisco

# Find documentation
wtf find me the react docs

# Get general knowledge
wtf what is rust programming language

Requirements

• Python 3.9 or higher
• An API key from Anthropic, OpenAI, or Google — OR run locally with Ollama (free, no API key needed!)

Optional: Web Search

wtf has limited web search by default (encyclopedic facts only). For full web search (weather, news, current events, documentation):

Get a free Brave Search API key:

1. Sign up at https://brave.com/search/api/ (free tier: 2,000 searches/month, no credit card)
2. Save your key: wtf here is my brave search api key YOUR_KEY_HERE

That's it! Now wtf can search for anything.

Hooks - Want wtf all the time?

Add wtf to your shell hooks for automatic assistance:

Error Hook

Automatically suggest wtf when commands fail:

wtf --setup-error-hook

Now whenever a command fails, you'll see:

💥 Command failed with exit code 1
   Run 'wtf' to analyze what went wrong

Command Not Found Hook

Suggest wtf when you mistype commands:

wtf --setup-not-found-hook

When you type a non-existent command:

❌ Command not found: gti
   Try: wtf how do I gti

Remove Hooks

Changed your mind?

wtf --remove-hooks

Supported shells: zsh, bash, fish

Configuration

Much of the configuration you can just do through telling wtf. Here are some config nouns that are useful in changing it:

• memories - remembers things you tell it or it discovers like what text editor you prefer
• personality - it has one. don't like it, just tell it to change
• allow list - commands that can run without asking
• history - its log of all your chats

Example config adjustments

# it will remember what you ask it to
wtf remember my name is dave and my favorite editor is emacs

# if you need more false encouragement in your life
wtf change your personality to be more of a super sycophant

# if you don't fear AI
wtf give yourself permission to run all commands

# if you're just too embarased
wtf forget everything we just did

If you're old fashioned you can also adjust these things as variables in a file. Configuration is stored in ~/.config/wtf/:

• config.json - Main configuration
• wtf.md - Your custom instructions
• allowlist.json - Commands that can run without permission
• memories.json - Your preferences and context
• history.jsonl - Conversation history
