AntigravityClaude Code

Cost: Pricing depends on the tools you pick; check each official pricing page.

Set it up

  1. Pick one goal and metric

    For example replies to outreach, ad ideas per week or landing page conversion.

  2. Set up the tools

    Open Antigravity, Claude Code. Load your offer, audience and examples of what already works.

  3. Generate, then review

    Have the agent research and draft. You approve every message, post or ad before it goes out.

  4. Measure and iterate

    Track the metric for a week, keep what works and feed the results back into the prompt.

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.
