Grok BotClaude Code

Cost: Grok Bot: from $30/mo; Claude Code: free plan, paid from $17/mo.

Set it up

  1. Gather the documents

    Collect statements, bills, invoices or tax documents for the period you want reviewed.

  2. Ask for an audit, not actions

    Have Grok Bot list findings, amounts and suggested next steps before it does anything.

  3. Approve each action

    Approve cancellations, disputes or payments one at a time. Never give an agent open-ended access to move money.

  4. Track the result

    Record what changed and what you saved so you can check it next month. This is not financial advice.

Copy the full setup prompt

Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Please:
1. Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like).
2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure.
3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data.
4. Finish with a checklist to run it again next time.
