Retriever AI
Retriever AI is a free AI browser agent that executes tasks on the open web and logged-in sites via Chrome extension, Cloud, API, MCP, and CLI/SDK, and returns completed results.
About Retriever AI
Retriever AI is a free AI browser agent that offers five ways to use it: Chrome extension, Cloud, API, MCP, and CLI & SDK. It executes tasks on the open web and on sites you're logged into, and returns completed results: for example, reading company websites, gathering evidence with sources, filling in forms, and scraping and organizing data. The free plan comes with 100 welcome credits and requires no credit card; Free Mode in the free tier means supported AI reasoning and Cloud browser time consume no credits, but a sponsored card is shown alongside results and daily fair-use limits apply. Paid plans provide ad-free operation and scheduled tasks, with credits issued monthly. You can also plug in your existing ChatGPT, Claude, API key, or local models to cover model calls, so those calls don't count against your daily fair-use allowance; you can also bring your own proxy when needed. In addition, agents.rtrvr.ai offers a store for AI agents with real-time pricing and self-service payment, where agents can make purchases with or without human approval.
Best for
Best use cases
Have an agent complete tasks on pages you're already logged into, with results returned directly — no need to interrupt your current work
Run scheduled tasks in bulk in the cloud on a schedule, such as posting daily, monitoring discussions, or following up with prospects every day
Use the API in your app to read job boards, fill in forms, and aggregate social information like calling a function, and return JSON
Via MCP in Claude, Codex, or Slack, give conversations the ability to access the web and do real work
Call the same agent from terminal scripts, pipelines, or your product backend
Compare before choosing
The official comparison page states: Browser Use gets stuck repeating the same steps, Firecrawl just outputs scraped URLs and may give wrong answers, while rtrvr plans a research path, verifies sources, and returns answers with citations.
The official comparison page states: Retriever AI is a free browser agent with built-in AI that can read company websites, gather evidence, and fill in forms on sites you're logged into; Clay organizes research around spreadsheets, data-enrichment vendors, and GTM workflows.
The official comparison page states: if your team already uses data-enrichment spreadsheets and needs a shared system for vendors, signals, and CRM updates, evaluate Clay first; Retriever's free tier includes Free Mode, purchased data and hosted agents may consume additional credits, and bringing your own API key is optional, not a requirement for free usage.
Features
Browser extension
Runs in your browser: on pages where you're already logged in and working, let Retriever carry out actions, with results returned while you work.
Cloud
Runs thousands of browsers in Retriever's cloud, executing on your schedule — ideal for tasks that need scale, such as posting daily, monitoring discussions, or following up with leads day by day.
API
Lets your apps access the web like calling a function: read job boards, fill in forms, and aggregate social information, returned as clean JSON.
MCP
Give Claude, Codex, or your Slack bot the ability to access the web and do real work through a single URL.
CLI & SDK
Use the same agent from your terminal, pipelines, or product backend — scriptable and schedulable.
Bring your own models & proxy
Connect ChatGPT, Claude, your own API key, or local models, with model calls covered by your provider and not counting against the daily fair-use allowance; you can also bring your own proxy when needed.
Store for AI agents
The agent store at agents.rtrvr.ai publishes prices, payment instructions, and everything needed to connect; agents can purchase autonomously or with human approval, and agents without a payment method can complete setup within the same session.
