Frequently asked questions

GEO (Generative Engine Optimization) is for answer engines like ChatGPT and Perplexity — AI that answers questions. AEO (AI Engine Optimization) is for action engines — coding agents like Claude Code, Codex, and Cursor that write and execute code. Sapient is the only platform that tracks both. Learn more: /blog/geo-for-developer-tools-is-different

Consumer GEO tools like Profound and Otterly track answer engines — whether ChatGPT mentions your brand. But for APIs and developer tools, mentions don't matter if the code doesn't work. Dev tools need to track action engines — whether Claude Code can actually use your API. That requires measuring tool call success rates, error recovery, and execution, not just brand mentions. Learn more: /blog/geo-for-developer-tools-is-different

17 platforms total: 7 answer engines (ChatGPT, Claude, Perplexity, Google AI Overviews, Google AI Mode, Gemini Search, Microsoft Copilot) and 10 coding agents (Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenClaw, OpenCode, Hermes, Pi, Kilo). See comparison: /blog/best-geo-tools-for-developer-tools-2026

Devtool Arena is our free, public leaderboard ranking APIs and developer tools by how well AI coding agents can use them. It's based on real benchmarks across discoverability, tool calls, and error rates. See results: /blog/we-tested-50-apis-in-coding-agents

Visibility Analytics tracks how often AI mentions your brand in conversations. API Performance measures how well AI coding agents can actually discover, call, and use your API endpoints—including tool calls, errors, and compatibility scores.

Common reasons: blocked AI crawlers in robots.txt, missing llms.txt file, no comparison content, or unclear error messages. We cover the 4 fixable reasons and step-by-step solutions: /blog/why-claude-code-not-recommending-your-library

There's a 4-layer decision stack: training data, web search, structured context (llms.txt, MCP), and execution feedback. Understanding this helps you optimize at each layer. Deep dive: /blog/how-coding-agents-decide-which-sdk-to-use

Start with the free Devtool Arena leaderboard to see where you rank. For continuous tracking, Sapient monitors 17 AI platforms daily and measures both visibility AND usability. Setup guide: /blog/how-to-track-ai-recommendations-for-your-api

Our lightweight middleware detects AI agents (Claude Code, OpenCode, ChatGPT, etc.) visiting your site. It takes one line of code to install and has zero impact on performance.

Yes. Sapient automatically identifies your competitors and tracks their visibility alongside yours. You'll see share of voice comparisons and opportunities where you can outrank them.

We offer plans for teams of all sizes, starting with a free tier to explore your visibility data. Paid plans scale based on the number of prompts, platforms, and competitors you track. Check our pricing page or book a demo for details.
