Otterly.AI vs Seen-By.AI (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

• Not for you if Google's AI Overviews or AI Mode are what you need checked
• Too light for agencies tracking clients week by week

• Watch out: prices are in pounds only, and results come from AI tools with no person checking them
