What is Synter?
Synter is an agentic advertising operations management platform that allows growth teams to run paid marketing campaigns across 43 advertising platforms using natural language instructions. Users describe their desired outcomes (e.g., 'pause campaigns with CPA over $150', 'shift budget to top-performing audiences') and AI agents execute approved actions in real-time through official platform APIs. Founder Joel Horwitz describes it as 'Cursor for Ads' - allowing marketers to work in natural language while AI handles execution.

Frequently asked questions
How is Synter different from other AI ad tools?
Synter agents execute in your ad accounts through official APIs - they don't just recommend actions. Each write goes through spend limits, approval gates, and an audit trail across 43 advertising platforms. It's not screen-scraping or browser automation.
Can I chat with my ad data like ChatGPT?
Yes. Ask in the Campaign IDE questions like 'which campaigns should I scale this week' or 'why did CPA move on Brand Search' and get answers backed by connected account data with recommended next actions.
Will the AI make changes without my approval?
You control the autonomy level. In conservative mode, all writes require approval. Routine optimizations can run automatically when enabled on the Scale plan. Major changes still need confirmation.
Which ad platforms does Synter support?
43 advertising platforms including Google Ads, Meta (Facebook & Instagram), LinkedIn, Microsoft Ads, Reddit, X, TikTok, Amazon, The Trade Desk, DV360, and retail media platforms like Walmart Connect and Instacart Ads.
How accurate are the AI recommendations?
Agents read live conversion and spend data from connected accounts. Every suggestion shows the evidence window and whether there's enough signal to act. Recommendations are based on actual account data, not generic advice.
How do I get started?
Sign up at synterai.com, add https://mcp.synterai.com/mcp as a connector in Claude Desktop or Claude Code, connect your ad accounts, then start asking your agent to manage campaigns. You can pull a 30-day report and launch campaigns in minutes.
