What is AgentSEO?
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.
What is Pieces?
Pieces is an AI productivity tool for developers built around a powerful idea: giving you a persistent, on-device memory of your work so you can capture, organize and recall the code snippets, context and materials you encounter throughout your day. Developers constantly deal with fragments — useful code snippets, error messages, links, commands, conversations — scattered across editors, browsers and chats, and lose enormous time re-finding or reconstructing them. Pieces acts as an intelligent long-term memory that helps you save and instantly retrieve all of it.
The tool lets you capture snippets and context with rich metadata automatically added by AI, then find them again through smart search and AI assistance. But its more ambitious feature is the "Long-Term Memory" copilot, which can passively remember your workflow — what you were working on, what you looked at, what you did — so you can ask it questions later like "what was that solution I found yesterday?" and get answers grounded in your own past activity. This addresses the very real problem of context loss and constant re-orientation that fragments a developer's focus.
Crucially, Pieces emphasizes running AI on-device for privacy, so your code and context stay local, and it integrates across the tools developers use — editors like VS Code and JetBrains, browsers, and more — to fit naturally into existing workflows. It also offers an AI copilot you can chat with about your code and saved materials. This makes it appealing to developers who want to reduce the friction of context switching, retain hard-won knowledge, and have an AI assistant that actually knows what they've been doing. As AI copilots become standard, ones with persistent, personal memory of your work stand out. For developers who want to capture their snippets and context and never lose track of what they did, Pieces offers a thoughtful, privacy-conscious and genuinely useful AI memory.
