Otterly.AI vs Siteline (2026): which should you pick?

Pick Otterly.AI if

• Fits if a daily read on ChatGPT, Perplexity, AI Overviews and Copilot is what you need
• Works for agencies that brand client reports through Looker Studio, from Standard

Look elsewhere if

• Skip it if Gemini, AI Mode or Claude matter to you, as they're paid add-ons on every plan, and all seven engines add $227 a month on Standard
• Not for you if you need white-label reports, as there aren't any
• Tight if you start on Lite, with 15 prompts, one workspace, no API or MCP, and no extra prompt packs
• Pricey if you outgrow Lite, as Standard is $160 a month yearly and extra prompts are $99 per 100, with 300 at most before Premium at $422
• Watch out: Claude is tracked through its API using the Haiku model, and crawler analytics needs server log files you upload

Pick Siteline if

• Fits if you want measured AI agent traffic from your server, not only simulated prompts
• Works for developer tools that want to see which coding agents read their docs

Look elsewhere if

• Skip it if you need to know which AI engines are tracked before you pay, as the table doesn't name them
• Not for you if you can't change your hosting or CDN setup, since it collects on the server side
• Tight if you stay free: prompt tracking, MCP and the API all start on Starter at $49 a month
• Watch out: prices are monthly only, with no yearly saving and no stated trial on paid plans
• Tight if you want Slack support, which starts on Scale at $99 a month
