Otterly.AI vs Radarkit in 2026: 7-engine GEO audit vs 4-engine cheap API monitoring
Two accessible AI visibility tools at the same $29/month entry price. Otterly.AI covers 7 engines with a built-in GEO audit. Radarkit covers 4 engines with API access across all plans but no audit.
Otterly.AI
Radarkit- Otterly.AI covers 7 AI engines on every plan: ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Claude, Gemini. Radarkit covers 4 engines (ChatGPT, Claude, Gemini, Perplexity). For brands that need Google AI Overviews, Google AI Mode, or Copilot visibility, Otterly.AI is the only choice here.
- Both tools start at $29/month for the cheapest paid plan. Otterly.AI Lite includes a GEO audit with optimization recommendations on every tier. Radarkit Lite includes API access plus competitor benchmarking. The same price, different priorities.
- Radarkit includes API access on Lite ($29/month) and above. Otterly.AI locks API access to Standard ($189/month). For developers and analysts building custom reporting pipelines on a budget, Radarkit is the clear choice.
- Neither tool offers white-label delivery. Both are designed primarily for in-house monitoring rather than agency delivery workflows. Agencies need a third platform focused on agency workflows.
- Otterly.AI Lite caps tracking at 15 prompts. Radarkit Lite is also limited in tracking volume and includes competitor benchmarking only on Growth ($79/month) and above. For competitive share-of-voice on a budget, Radarkit requires a tier jump.
- Otterly.AI Standard includes MCP integration for agent workflows. Radarkit has API access but no MCP integration. For teams building AI agent stacks that need to query visibility data, Otterly.AI Standard is the more useful choice.
- Both platforms support Generative Engine Optimization (GEO) workflows at the data layer. Otterly ships the audit. Radarkit lets you build the analysis yourself by pulling citation source data into your own tools.
If you are choosing between Otterly.AI and Radarkit, you are weighing two of the cheapest paid AI visibility tools in the category. Both start at $29/month. How does Otterly.AI compare to Radarkit for teams on tight budgets who need Generative Engine Optimization (GEO) coverage? Otterly.AI covers 7 AI engines including Google AI Overviews, Google AI Mode, Microsoft Copilot, and Claude, and ships a GEO audit with optimization recommendations on every tier. Radarkit covers 4 engines (ChatGPT, Claude, Gemini, and Perplexity), includes API access on Lite, and skips the GEO audit layer. The split is at engine breadth and audit versus API-first simplicity. Otterly.AI wins on coverage and audit; Radarkit wins on API-first architecture at the entry tier. The right pick depends on whether you need Google AI Overviews visibility and a built-in GEO audit, or whether 4 engine coverage plus API access from day one is enough.
The tools at a glance
Otterly.AI
Track brand visibility across 7 AI engines from $29/month with API and MCP support
Otterly.AI is an AI search monitoring platform that tracks how and where your brand appears across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Claude, and Gemini. It positions itself as a Generative Engine Optimization (GEO) tool, meaning it goes beyond showing you where you appear and actively recommends changes to improve your citations.
The platform launched with one of the most competitive price points in the category. At $29/month for the Lite plan, you get real tracking across all 7 AI models, answer ranking monitoring, citation link analysis, and a GEO audit with optimization recommendations. The Lite plan covers more engines than most competitors at the same price point.
The trade-off versus Radarkit is API access at the entry tier. Otterly.AI Lite does not include API access or MCP integration. Both unlock at Standard ($189/month). Radarkit Lite includes API access from day one. For teams that need API access on the cheapest plan, Radarkit is more attractive; for teams that need broader engine coverage and a built-in GEO audit, Otterly.AI is the answer.

Radarkit
AI brand monitoring across ChatGPT, Claude, Gemini, and Perplexity with API access
Radarkit monitors brand mentions and citations across ChatGPT, Claude, Gemini, and Perplexity. The platform tracks how often your brand appears in AI-generated answers, which sources the AI models cite, and how your visibility compares to competitors over time.
Where Radarkit stands out is its pricing accessibility. At $29/month for the Lite plan, it is one of the cheapest ways to get structured AI visibility data with API access included from day one. Most tools at this price point are either read-only dashboards or restrict API use to higher tiers, which makes Radarkit appealing for developers and data teams building custom reporting pipelines.
The trade-off versus Otterly.AI is engine breadth and audit depth. Radarkit does not track Google AI Overviews, Google AI Mode, or Microsoft Copilot, and it does not include a built-in GEO audit or MCP integration on any tier. For teams whose AI visibility narrative must include Google surfaces, Radarkit alone is not enough. For teams focused on ChatGPT, Claude, Gemini, and Perplexity with API access on a budget, Radarkit is a strong fit.
