Our verdict (from published data)
Pick OtterlyAI if you want a predictable bill and daily tracking on the four engines it covers by default (ChatGPT, Google AI Overviews, Perplexity and Copilot), with Gemini, AI Mode and Claude as paid add-ons. Pick Rankscale if you want more engines without add-ons (17+ listed on every plan) and control over how often each prompt runs, and you're comfortable budgeting in credits.
Who should pick which
- Beginners who want a fixed price: OtterlyAI Lite, 15 prompts checked daily.
- SEOs who want Claude, Grok or DeepSeek: Rankscale. OtterlyAI doesn't list Grok or DeepSeek and charges extra for Claude.
- Agencies: both can work. OtterlyAI has unlimited team members on every plan and an agency partner program; Rankscale lets you split credits across brands and adds white-label dashboards on Growth.
