AI-assisted data annotation companion for faster, smarter labeling
The extension proposes likely labels or annotations as you work, so you can confirm a suggestion instead of classifying each item from zero.
Runs entirely in the browser via the Chrome Web Store, with no server setup, plugin dependencies, or account creation required.
Acts as a companion layer over the annotation pages you already use, so there is no need to migrate your dataset or tooling.
The developer declares that user data is not sold or shared and is not used for unrelated purposes.

Track page changes, price drops and back-in-stock alerts across e-commerce sites, with notifications when something moves.
Extract structured data from websites, fill forms, click through flows and trigger Zapier, Make.com, IFTTT or n8n chains.
Provides a richer all-in-one workspace with writing and painting tools, but is less focused on customizable scraping macros.
