MultiOn
AI web agent that autonomously browses websites, fills forms, and completes multi-step online tasks from natural language instructions via browser extension or API.
MultiOn is an AI web agent platform that executes complex multi-step browser tasks autonomously from plain-English instructions - booking appointments, completing forms, scraping data, and navigating workflows without requiring Selenium code or RPA scripts. The platform combines a browser extension for interactive use with a developer API for embedding web automation into applications and LLM pipelines. MultiOn is built on a vision-language model that reads and interacts with web pages as a human would, handling dynamic JavaScript-rendered pages that traditional scraping tools cannot process. Backed by notable investors including Nat Friedman and Daniel Gross, MultiOn is used by developers building AI agents that require real-world web interaction capabilities.
Key Features
- Natural language web task execution - describe a task in plain English and the agent completes it autonomously
- Vision-language model that reads page layouts visually - works on JavaScript-rendered pages without DOM parsing
- Multi-step workflow completion across login walls, multi-page forms, and dynamic checkout flows
- Developer API for embedding web browsing capabilities into LLM applications and AI agent pipelines
- Chrome extension for supervised interactive use where users observe and guide agent task execution
- Task recording and replay for creating reusable automation scripts from single natural language runs
- Session isolation for concurrent agent instances running parallel web tasks without interference
Use Cases
- Developers building AI personal assistants that need to interact with web services without official APIs
- Operations teams automating repetitive data entry and form submission workflows across web portals
- Researchers collecting web data from dynamic pages that traditional scrapers and APIs cannot access
- Product teams testing web application flows with AI-driven exploratory automation rather than scripted Selenium tests
Pros
- Vision-based browser interaction handles dynamic JavaScript SPAs where traditional DOM-scraping tools fail completely
- Natural language task definition eliminates Selenium/Playwright scripting for common web automation use cases
- Developer API makes web browsing a composable capability for LLM agent pipelines - no infrastructure management required
Cons
- Autonomous web tasks can fail on complex multi-step workflows - human-in-the-loop supervision recommended for critical tasks
- Credit-based API pricing can become expensive for high-frequency or long web sessions with many page interactions
- Legal and terms-of-service considerations vary per website - automated access violates ToS on some platforms
