What Synter Does
Attribution Data Plus Execution
Synter reads performance data from all 14 connected platforms and acts on it. If ROAS drops below threshold, the AI Agent adjusts bids. If a creative is underperforming, it pauses it and queues a replacement. Attribution informs execution.
AI Agents That Execute
Synter AI Agents do not surface recommendations and wait for you to act. They execute: campaign creation, bid changes, budget reallocation, audience uploads, and creative testing across all 14 platforms from a single conversational interface.
Direct API. No Middleware.
Synter connects directly to each ad platform API. No third-party data pipeline. No sync delays. When you instruct the agent to make a change, it executes immediately against the live platform.
MCP Server with 100+ Tools
Synter publishes an MCP server at syntermedia.ai/mcp with 100+ agent tools. Connect Claude Desktop or any MCP-compatible client to manage campaigns, pull cross-platform data, and adjust spend via natural language.
What Cometly Does Well
Multi-Touch Attribution
Cometly provides dedicated multi-touch attribution modeling, showing which channels and touchpoints contribute to conversions. For teams whose primary need is measurement accuracy across the full funnel, Cometly offers a focused attribution solution.
Server-Side Pixel Tracking
Cometly uses server-side event tracking to capture conversions that browser-based pixels miss. This helps with iOS and cookie restrictions. Synter does not offer a proprietary server-side pixel.
Revenue Attribution Dashboards
Cometly focuses on connecting ad spend to actual revenue, surfacing ROAS at the campaign and ad level. Teams whose primary challenge is attribution accuracy may find Cometly's dashboards purpose-built for that use case.
Limitations to Consider
Cometly does not execute campaigns, adjust bids, create ads, or make any changes to ad platforms. It is a measurement and analytics tool. Teams that want to close the loop between insight and action need an execution platform alongside it.
Who Should Choose Synter
- Teams that want AI Agents to act on performance data, not just display it
- Advertisers managing campaigns across multiple platforms from one interface
- Performance marketers who need execution, not just attribution
- Agencies that want to manage budgets, creatives, and audiences via natural language

Who Should Choose Cometly
