Set Up Terminal AI

Get Claude Code, OpenAI Codex, or Google Gemini working with RiteMark.

Terminal-based AIs work alongside RiteMark to help you write. They can read your documents, make edits, and understand your full project context.

Claude Code is the best terminal AI for writing with RiteMark. It understands markdown, makes precise edits, and handles long documents well.

Install Claude Code

  1. Install via Homebrew:

    brew install claude-code

  2. Or via npm:

    npm install -g @anthropic-ai/claude-code

  3. Authenticate:

    claude auth

    Follow the prompts to sign in with your Anthropic account.

Using Claude Code with RiteMark

  1. Open your document in RiteMark
  2. Open the terminal: View → Terminal or `Ctrl+``
  3. Navigate to your document folder: 
    cd /path/to/your/documents
  4. Start Claude: 
    claude
  5. Ask Claude to help: 
    Read my-document.md and suggest improvements

Example Prompts

  • "Make the introduction more engaging"
  • "Restructure this document with better headings"
  • "Summarize the key points at the top"
  • "Make section 3 more concise"
  • "Add examples to illustrate each concept"

OpenAI Codex

Good for technical documentation and code-related writing.

Install

  1. Install OpenAI CLI:

    pip install openai

  2. Set API key:

    export OPENAI_API_KEY='your-key-here'

    Or add to your shell profile (~/.zshrc):

    echo 'export OPENAI_API_KEY="your-key"' >> ~/.zshrc

Using with RiteMark

Codex CLI usage varies by tool. Refer to OpenAI documentation for current CLI options.

Google Gemini

Fast for quick edits and brainstorming.

Install

  1. Install Gemini CLI:

    pip install google-generativeai

  2. Configure API key:

    export GOOGLE_API_KEY='your-key-here'

Using with RiteMark

Refer to Google's Gemini CLI documentation for current usage.

Tips for All Terminal AIs

Always start in the right directory:

cd ~/Documents/my-project

This helps the AI understand your project structure.

Be Specific About Files

Tell the AI which file to work on:

  • "Edit introduction.md"
  • "Read chapters/chapter-1.md and improve it"

Work Section by Section

Don't ask for everything at once:

  1. "Improve the opening paragraph"
  2. "Now make section 2 clearer"
  3. "Add a conclusion"

Give Context

Tell the AI what you're writing:

  • "This is a blog post for developers"
  • "This is a user manual for beginners"
  • "This is a sales proposal"

Google Gemini Speed, quick iterations Brainstorming, drafts

Troubleshooting

"Command not found"

The AI CLI isn't installed or isn't in your PATH. Reinstall following the instructions above.

Authentication errors

Re-authenticate with your API provider:

  • Claude: claude auth
  • OpenAI: Check your API key
  • Gemini: Check your API key

AI can't see my file

Make sure you're in the correct directory:

pwd  # shows current directory
ls   # lists files here

Changes don't appear in RiteMark

  1. RiteMark should auto-detect file changes
  2. If not, reload: Cmd+Shift+P → "Reload Window"
