Runneth Built by the team behind Motion, for brands and agencies running Meta or TikTok ads. Each team gets a dedicated, always-on cloud computer and a shared brain, so it learns your team's judgement and keeps working. It is read-only until an owner or admin turns on launching, and editing live ads needs a second switch. Starter starts at $999 a month. See [Runneth pricing](/prices/runneth-pricing). ## 2. Adstellar An AI media buyer for Meta. Its agent "pauses waste, scales winners, and adjusts budgets", and it launches ads too. We found no per-change approval step on its site. $100 a month plus $2 per 1,000 credits, with a 7-day trial. ## 3. Ryze Covers Google, Meta, TikTok and LinkedIn. In Slack, each recommendation comes with Approve and Dismiss buttons. Paid Ads is $89 a month. Its Slack page shows "Get early access". ## 4. Markifact Works across 14 ad platforms, in Markifact, Slack or WhatsApp. "Nothing goes live without you." It has a ready-made Meta Ads AI Slack Agent template. pro is $79 a month. ## 5. Madgicx A Meta-focused AI ads platform. Its AI Marketer comes with Launch buttons. No Slack feature found on its site. Price inside the app, 7-day trial. See [Madgicx compared](/compare/madgicx). ## 6. Polar Operator The Slack agent inside Polar Analytics, a Shopify-focused data platform. It reads Meta alongside Google Ads, Amazon Ads and Klaviyo, and holds any outside change for a person. ## 7. Birch Formerly Revealbot. Not an AI agent in the chat sense: it runs your rules, with "20+ actions, checked every 15 minutes". Essential is $49 a month. ## 8. Marxx We make Marxx. It reads the Meta account and tags creative by hook, angle, format and offer. Each client's Slack channel gets leads, alerts and competitor ads, and @Marxx answers there. It never changes ads from Slack. See [Marxx in Slack](/features/slack). ## Reads only or can change: how to decide Start read-only, then widen. Say your daily Meta budget is INR 20,000. 1. **Week 1 to 4, read-only.** Ask the agent questions and compare its answers with Ads Manager. 2. **Then allow changes with a yes.** Ryze and Markifact ask each time. Set a rule for yourself, such as any change over INR 2,000 a day needs a second person. 3. **Only then, more freedom.** Runneth has no per-change approval step once its switches are on, and we found none on Adstellar's site. Give that only once you trust the agent's calls. Before you connect anything, run the [Meta ads account audit checklist](/templates/account-audit-checklist-meta-ads).
