What Eva is
Eva is an AI assistant for Meta ads that lives in the team chat in Telegram. She answers questions about the ad account with numbers, checks every campaign on a schedule and acts inside limits that I set. She runs on Claude Code, the coding agent from Anthropic, on my own Claude plan.
She writes like an experienced colleague: one or two sentences, numbers instead of adjectives. Someone asks what leads cost this week, and a few seconds later the answer is there: cost per lead, cost per qualified lead from the CRM, the best and the worst campaign.
Why she works like a specialist, not a toy
Reports are the easy part. What makes the difference is the rule book she follows on every decision:
- One variable at a time. She copies the winning ad and changes one thing, so you know what made the difference.
- Judge on day 3, by the cost of a qualified lead. Not by clicks and not by the cost of any lead. A lead counts when the CRM says it became a real conversation with a customer.
- Meta's rules before launch. Every new ad is checked against Meta's advertising standards before it goes live.
On top of that she works inside guardrails: budgets, what she may pause on her own and what needs my yes. When she acts, she says it in the chat as a fact, for example "Retarget 2: qualified lead 340 kr against 93 average. Pausing it now." The team always knows what happened and why.
How she runs every 20 minutes
A scheduler starts Claude Code every 20 minutes. Claude reads new messages in the chat, pulls fresh numbers from the Meta Marketing API, checks them against the rule book and writes a short answer or a decision. Then the run stops until the next one.
Every launch is reviewed afterwards and goes into her case library, so the next launch starts from what worked last time.
Honest limits. Eva is as good as her rule book, her data and the limits you give her. That is why part 1 is read only: she reads and reports, and nothing in the ad account can change. Decisions and changes come later, with clear limits.
Who this guide is for
Marketers and business owners who run Meta ads themselves or with a small team, and agencies that want faster answers for clients. You do not need to be a developer: Claude Code writes the code, you decide the rules. You should be comfortable running a command in a terminal and pasting a token into a file.
