- Your media mix extends beyond Meta and Google: LinkedIn, Reddit, TikTok, X, Microsoft, Pinterest, Amazon, Spotify, and more.
- You want attribution plus execution in one product, with conversion data feeding agent decisions.
Use Cometly if...

Synter Replaces Cometly for Teams That Want Execution
Synter starts where Cometly stops. Cometly reports what happened. Synter makes the next thing happen. The AI Agents in Synter take the conversion data, decide what to do next, and execute the change directly in Google, Meta, LinkedIn, Reddit, TikTok, X, Microsoft, Snapchat, Pinterest, Amazon, Spotify, Taboola, YouTube, or Display without requiring a manual step in each ad manager.
Synter ships with 7-platform server-side tracking. That covers the core value Cometly provides: first-party conversion capture that survives browser-level privacy restrictions. The difference is that Synter feeds those conversion events into an agent that takes action, not a dashboard that waits for a human to interpret.

Where Synter Wins: Execution Across 14 Platforms
Synter connects through direct APIs to Google Ads, Meta, LinkedIn, TikTok, Microsoft Ads, Snapchat, Pinterest, Reddit, Taboola, X, Spotify, Amazon, YouTube, and Display. The AI Agents handle the platform-specific complexity. You describe what you want in plain English. The agents plan the campaign, generate creative, launch on the right platforms, and monitor performance.
Cometly is focused on Meta and Google attribution. For teams running LinkedIn for B2B, Reddit for community audiences, TikTok for younger demos, or Microsoft for lower-CPC search, Cometly does not provide tracking or execution. Synter does both.
Where Synter Wins: Attribution Plus Action
Attribution without execution leaves work on the table. A team using Cometly learns which ads drove revenue, then goes into Meta Ads Manager to shift budget. Synter skips that second step. The conversion data goes into the AI Agent, and the agent reallocates budget across platforms in the same session.
Attribution feeds agent decisions
Synter uses 7-platform server-side tracking to feed conversion signal into AI Agent decisions. When Meta CAPI returns a purchase, the agent adjusts Meta budget. When Google Enhanced Conversions fire, the agent updates Google bidding. You get attribution and the reallocation that should follow, in one product.
