Everything Otto can do
A complete toolkit for browser automation powered by AI
Otto clicks buttons, links, and interactive elements just like you would.
Fill out forms, write messages, and enter data with natural language commands.
Navigate long pages and find content anywhere on the screen.
Open URLs, switch tabs, and browse the web autonomously.
Otto understands what's on screen using AI vision to make smart decisions.
Open, switch between, and close multiple browser tabs to handle complex multi-step tasks.
Works with Chrome, Brave, Arc, Edge, and all Chromium browsers.
Control your entire Mac with natural language commands from the terminal.
A smarter approach to automation
Otto uses text-based algorithms and fuzzy matching instead of expensive vision models
Much cheaper
By relying on text algorithms and fuzzy searches rather than image-based AI, Otto costs a fraction of other browser automation tools.
Much faster
Text processing is significantly faster than vision models. Otto executes tasks quickly without waiting for expensive API calls.
Early but evolving
Otto is new and actively developed. You may encounter rough edges, but we're shipping improvements fast. Your feedback shapes the roadmap.
