TL;DR
Synter is the AI Agent Operator for paid media. You direct, the agents execute. Synter plans campaigns, generates creative, launches ads, and optimizes performance across 27 platforms through direct API connections. Synter also includes server-side conversion tracking across 7 platforms, so attribution is built in.
Cometly is an attribution reporting tool focused on Meta and Google. It captures conversion events through a first-party pixel and shows which ads drove revenue.
Use Synter if...
- You want AI Agents that plan, launch, and optimize campaigns, not just a dashboard that reports on them.
- 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...
- Your only unsolved problem is Meta and Google attribution accuracy, and you already have a campaign workflow that works.
- You do not need agent execution and prefer a reporting-only product.
When Synter Can Replace or Complement Cometly
Synter is designed around campaign execution. Its AI Agents can take conversion data, recommend what to do next, and execute approved changes across supported connections in a 27-platform catalog. Cometly approaches the workflow from attribution first and is expanding execution through its newer AI Ads Manager.
Synter's server-side conversion router has 13 implemented destinations. It combines first-party event capture with an execution layer that can recommend and, with approval, act on what those events show. Cometly remains the more attribution-focused product, while Synter emphasizes the connection between measurement and campaign operations.

Where Synter Wins: Execution Across 27 Platforms
Synter connects through direct APIs to Google Ads, Meta, LinkedIn, TikTok, Microsoft Ads, Snapchat, Pinterest, Reddit, Taboola, X, Spotify, Amazon, YouTube, Display, and more. 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 remains attribution-first and now markets an AI Ads Manager, plus data sync for channels including LinkedIn and Microsoft. Its execution layer is newer and narrower than Synter's operating model, so teams should compare specific channel actions rather than treating either platform as universally complete.
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's server-side adapters send advertiser conversion events to supported ad platforms, including Meta through CAPI and Google through Enhanced Conversions. Verified conversion signals can then inform an approved budget or bidding change in the same workflow.

What is Cometly?
Cometly is an attribution-first platform built around first-party tracking and revenue attribution by ad, ad set, and campaign. It now also markets an AI Ads Manager, so it is no longer accurate to describe the product as reporting-only; attribution remains its established focus.
Our Recommendation: Synter
If broad, approval-gated campaign execution is the priority, Synter is the stronger fit. If attribution depth is the priority, evaluate Cometly's established reporting alongside its newer AI Ads Manager. Synter can replace Cometly where its tracking meets your needs, or sit alongside it when a team wants Cometly's attribution layer.
