Open Comet
Open Comet is a Chrome extension that acts as an autonomous AI browser agent for browsing, research, editing, and data extraction inside your existing browser. It supports multiple AI providers, including local Ollama setups, and offers a free plan plus a paid monthly option.
Overview
Open Comet is an autonomous AI browser agent delivered as a Chrome extension. It runs in a browser sidepanel and uses visual grounding plus DOM analysis to read pages, decide what to do next, and carry out multi-step tasks such as browsing, researching, editing, and extracting data.
The product is designed to work inside browsers people already use, including Chrome, Chromium, Brave, and Edge. It supports multiple AI providers and also offers a local setup with Ollama, which gives users the option to run the agent without a cloud API key.
Features
Autonomous browsing
Uses screenshot plus DOM grounding to click, type, scroll, and interact with pages inside the active tab.
In-page editing
Highlights a text field and lets you draft, refine, translate, or improve text directly on the page.
Data extraction
Extracts tables, lists, and structured page data to JSON, CSV, or plain text.
Skills system
Creates reusable agent behaviors or macros that can be triggered with one command.
Ask mode
Offers an approval-based mode where every browser action pauses for explicit user confirmation.
Use Cases
Shopping research
Use Open Comet to compare products, check prices across stores, and read reviews while staying on the current tab.
Multi-page research
Use the deep research workflow to gather information from multiple pages and turn it into a cited summary for a topic or question.
Structured data capture
Use the extraction tools to pull tables or lists from a webpage and export them as JSON, CSV, or plain text.
On-page writing assistance
Use in-page editing to draft or refine text in forms, content fields, or message boxes without leaving the page.
Supervised automation
Use Ask Mode when a task is sensitive and you want to approve each browser action before it executes.
