AgentSEO vs Greptile: Which Is Better in 2026?

AgentSEO gives teams and AI agents a way to work with SEO research and search visibility data through a developer-friendly API. It is designed for marketers, SEO practitioners, agencies, and developers who want to bring search research into their own applications and workflows instead of switching between separate tools for each task.

The product provides a REST API, a hosted Model Context Protocol (MCP) server, and client libraries for Node.js and Python. These interfaces let a developer or connected AI assistant request supported SEO data from a project or automation. AgentSEO focuses on practical research workflows such as keyword research, search engine results page (SERP) analysis, competitor research, rank tracking, content gap discovery, and visibility checks for AI-powered search experiences.

A team can use the API to gather search results for a topic, compare competing pages, find keyword opportunities, or connect ranking and visibility data to an internal dashboard. An agency can use it as a data layer within its own reporting or research process. Developers can connect the service to scripts, applications, and AI-agent workflows using the interface that fits their environment. The MCP server is intended for compatible AI clients, while the REST API and SDKs support direct integration from software.

AgentSEO is built for people who need structured search data that can be reused across workflows. Rather than presenting SEO as only a manual dashboard activity, it makes research capabilities available to software and agents through documented interfaces. Users should choose the relevant operation for their needs and review the returned data as part of their own analysis; search visibility changes over time and no tool can guarantee a specific ranking or business result.

AgentSEO offers a free entry tier alongside paid plans. Current plan limits and prices are listed on the official pricing page at agentseo.dev/pricing. Developers can review the documentation for API access, MCP setup, and SDK usage before integrating. Visit agentseo.dev to explore the product and documentation.

Greptile is an AI tool that deeply understands your entire codebase, using that full context to provide thorough AI code reviews and answer questions about how your code works. Its defining strength is whole-codebase comprehension: rather than looking at a single file or diff in isolation, Greptile builds an understanding of your whole repository, so its reviews and answers account for how changes affect the broader system — catching issues that tools with narrow context miss.

The most popular use of Greptile is AI code review. When a pull request is opened, Greptile reviews it with knowledge of the entire codebase, identifying bugs, potential problems and inconsistencies, and leaving detailed, context-aware comments — much like a senior engineer who knows the whole project would. Because it understands the relationships and conventions across your code, it can flag subtle issues that arise from how a change interacts with other parts of the system, not just surface-level problems in the diff. This makes its feedback notably more insightful than context-limited reviewers.

Beyond review, Greptile's codebase understanding powers the ability to ask questions about your code in natural language and get accurate answers grounded in your actual repository — useful for onboarding new developers, understanding unfamiliar areas of a large codebase, and reducing the time spent digging through code to figure out how something works. It integrates with code hosting platforms and fits into existing workflows. This makes Greptile valuable for engineering teams that want higher-quality, context-aware code review and faster codebase comprehension, especially in large or complex projects. As AI proves increasingly adept at understanding code at scale, tools that leverage full-codebase context for review and Q&A represent a meaningful step beyond simpler assistants. For teams that want an AI that truly understands their whole codebase to review code and answer questions, Greptile offers a powerful and differentiated solution.
